Background: OME is an accumulation of serous or mucoid fluid in the middle ear cavity with an intact tympanic membrane and without any sign of acute infection., Aims: This study aimed to determine the prevalence of otitis media with effusion among preschool and school-age children aged 1-10 years in private and public schools in Calabar municipality and the correlations between otoscopic findings and Jerger's diagnostic criteria among study participants., Methods: This school-based descriptive cross-sectional study used a multistage sampling technique to recruit participants. The Institutional Ethical Committee approved the study. Consent and assent were obtained from parents/guardians of children aged < 6 years and >7 years, respectively. A structured questionnaire was used to obtain sociodemographic characteristics, symptoms, and possible risk factors for otitis media with effusion. In addition, ear, nose, and throat (ENT) examinations and tympanometry were performed for each participant. Jerger's type B and C tympanograms were the diagnostic criteria for otitis media with effusion. The data were analyzed using IBM SPSS version 25, and the threshold for statistical significance was set at P < 0.05., Results: The overall prevalence of OME was 13.8%, with P values ≤ 0.001, P = 0.597, and P = 0.007 for daycare (45.85%), public schools (14.7%), and females, respectively. Jerger type B tympanograms had a strong positive correlation with middle ear fluid (r = 0.777) on otoscopy, Jerger type C tympanograms with dull TM (r = 0.687), and retracted TM (r = 0.774)., Conclusion: Otitis media with effusion was more prevalent among preschool children aged 1-2 years in public schools and among female children in Calabar municipalit. The otoscopic results of otitis media with effusion were consistent with Jerger's diagnostic criteria in our study., (Copyright © 2024 Copyright: © 2024 Nigerian Journal of Clinical Practice.)

Objective: Since December 2021, the number of children with COVID-19 infections has increased. Sequelae in children have not been well-described. Our goal was to determine if children with a history of COVID-19 infection (C19 group) were more likely to present with recurrent acute otitis media (rAOM) or post-ventilation tube otorrhea (VTO) than children who had no history of COVID-19 infection (NoC19 group)., Methods: Charts of consecutive children presenting at a pediatric otolaryngology clinic from March-May 2022 were reviewed. Demographics, COVID-19 test history, comorbidities, ultimate diagnosis, physical exam findings, and management plan were included. No children had a known COVID-19 infection at the time of visit., Results: 524 children were included, 228 (43.5 %) girls and 296 (56.5 %) boys. Mean age was 5 years (95 % CI 4.6-5.4). 115 (21.9 %) had a history of COVID-19 infection. 104 (19.8 %) had a diagnosis of rAOM or VTO, 26.1 % (30/115) children in C19 and 18.1 % (74/409) children in NoC19 (Fisher's Exact p = .04, OR = 1.6). For children without ventilation tubes in place, 23.5 % (27/115) in C19 had rAOM versus 15.2 % (62/409) in NoC19 (p = .03, OR = 1.7). 18.3 % (21/115) of the C19 group had nasal congestion compared to 6.6 % (27/409) of the NoC19 group (p < .001, OR = 3.2). There was no difference in incidence of otitis media with effusion, tonsil/adenoid hypertrophy, sleep-disordered breathing, or epistaxis between the groups., Conclusion: Infection with COVID-19 may be associated with an increased risk of rAOM and VTO in children. This may affect healthcare utilization by increasing the need for pediatric and otolaryngologic care., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to disclose., (Copyright © 2024.

Objective: To assess the prevalence of otitis media with effusion (OME) among children who attended a tertiary level audiologic center 2 and 3 years after the COVID-19 lockdown, and to determine the impact of temporary interruption of day care center attendance on chronic OME., Study Design: Retrospective study., Setting: Tertiary level referral audiologic center., Methods: We assessed the prevalence of OME among children aged 6 months to 12 years in 3 different periods (May-June 2022, January-February 2023, and May-June 2023) and compared the results with those of the corresponding periods before the COVID-19 lockdown. We also compared the disease resolution rates between a subgroup of children with chronic OME who interrupted day care center attendance for a 2-month period (Subgroup A) and a similar subgroup who continued attending day care centers (Subgroup B)., Results: The prevalence of OME was 38.5% (138/358) in May-June 2022, 51.9% (193/372) in January-February 2023, and 40.9% (149/364) in May-June 2023. No significant prevalence differences were observed between the periods May-June 2019, May-June 2022, and May-June 2023 (P = .78), and between the periods January-February 2020 and January-February 2023 (P = .93). At the May-June 2023 assessment, the children belonging to Subgroup A presented a greater rate of disease resolution (85.7%, 18/21) than the children belonging to Subgroup B (32%, 8/25, P < .001)., Conclusion: This study suggests that the prevalence of OME has returned to prelockdown levels, and that interrupting day care center attendance for a 2-month period could be effective in resolving most cases of chronic OME., (© 2024 American Academy of Otolaryngology–Head and Neck Surgery Foundation.)

Background: Canine middle ear effusion (MEE) is usually asymptomatic, being an incidental finding when computed tomography or magnetic resonance imaging (MRI) of the head is performed for other reasons unrelated to otic disease. The clinical relevance of the presence of material in the tympanic bulla (TB) remains uncertain, and more detail about its prevalence and appearance in MRI are required., Objective: To assess the prevalence of presence of material within the TB of French bulldogs (FB) with no clinical signs suggestive of otitis (externa, media or interna) that underwent high-field MRI for other medical reasons., Animals: Two hundred fifty-two TB of 126 FB were included in this study., Materials and Methods: Nonexperimental retrospective study in which MRI images were evaluated by a board-certified veterinary radiologist., Results: Fifty-eight per cent of the dogs had material in the TB lumen (46% of the TB) and 59% were bilaterally affected. The signal intensity of this material related to the grey matter was variable on T1w and mainly hyperintense on T2w sequences., Conclusion and Clinical Relevance: FB are predisposed to MEE. This is important when assessing imaging studies of TB of FB with chronic otitis externa, as high percentage of cases may have concurrent MEE. MRI findings in FB with MEE are characterised by a hyperintense signal to the grey matter on T2w in most cases and variable on T1w sequences., (© 2024 ESVD and ACVD.)

Objective: This study aims to analyze the onset of otitis media secretory, the peak period of infection with the Omicron strain of SARS-CoV-2 virus, and the time of transmigration during a pandemic of the Omicron strain. Additionally, the study aims to investigate to study the presence of SARS-CoV-2 virus in the middle ear cavity of patients with otitis media secretory and the survival time through a new method for detecting SARS-CoV-2 virus antigen in middle ear effusion., Methods: Retrospective comparison of the incidence of otitis media secretory during infection with SARS-CoV-2 virus Omicron strain from December 15, 2022, to January 15, 2023, versus the noninfection period from December 15, 2021, to January 15, 2022. We used a questionnaire star application to investigate the demographic and epidemiological characteristics of the 40 patients with otitis media secretory who participated in this study were investigated. A novel coronavirus (2019-nCoV) antigen detection kit (colloidal gold method) was used to detect middle ear effusion in patients with otitis media secretory. The data were statistically analyzed using SPSS 29.0 software. The measurement data are expressed as x ± s , the count data are expressed as the number of cases (%), and the data were compared using the χ 2 test. p < 0.05 indicated a statistically significant difference., Results: During the SARS-CoV-2 virus Omicron strain pandemic, the incidence of otitis media secretory increased by 15% compared with the noninfection period. The peak infection period for the SARS-CoV-2 virus Omicron strain was December 25, 2022, and December 15, 2022, and the peak time of conversion was 7 to 9 days after the infection. Middle ear effusion SARS-CoV-2 virus antigen testing was performed in patients with otitis media secretory after conversion; 5 patients (12%) were positive, and 35 patients (88%) were negative. The disease duration in patients with negative results was more than 3 weeks., Conclusions: Otitis media secretory is one of the most common ear complications after infection with the Omicron strain of SARS-CoV-2 virus, and the significantly higher incidence is associated with middle ear viral infection. Middle ear effusion SARS-CoV-2 virus antigen test detected the virus, which survived longer in the middle ear effusion than in the nasal cavity. The middle ear effusion test can detect SARS-CoV-2 virus antigen and determine whether the organism contains virus residue., Competing Interests: Conflict of interest: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 The Author(s).

Objective: We previously reported pandemic year (2020) intraoperative middle ear effusion (MEE) rate at time of bilateral myringotomy tube (BMT) placement was 18% lower compared to pre-pandemic year (2019). After mandatory stay at home orders (MSHO) and pandemic social distancing precautions were relaxed, we aimed to assess the impact of a persistent pandemic with new COVID-19 variants on MEE presence during BMT., Methods: This study is a retrospective chart summary exempted by Nemours institutional review board at a single tertiary children's hospital. Children < 18 years who underwent BMT during March 1, 2019-June 31, 2019 (pre-COVID), March 1, 2020-June 31, 2020 (PY1), and March 1, 2021-June 31, 2021 (PY2) were included. Statistical analysis included chi-squared and KruskalWallis., Results: A total of 1069 BMTs were reviewed: 551 (52%) during pre-COVID, 227 (21%) during PY1, and 291 (27%) during PY2. There were no significant differences in age, sex, or BMI across comparison groups. Intraoperative MEE was significantly higher pre-COVID (83%) compared to PY1 (65%) and PY2 (69%) ( P < .001) despite a small rebound in PY2., Conclusion: Intraoperative MEE remains lower in subsequent pandemic years despite relaxed public health measures and may be impacted by persistent public health measures like masking, lower return to daycare, variable social distancing, and/or change to access to health care., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Aim: To evaluate the influencing factors of otitis media with effusion (OME) in children with adenoid hypertrophy and to provide evidence for clinical treatment and care of children with adenoid hypertrophy., Design: A retrospective study., Methods: Preschool children with adenoid hypertrophy treated in our hospital from 1 January 2021 to 30 July 2022 were included. We analysed the characteristics of OME and non-OME children with adenoid hypertrophy. Pearson correlation analysis and logistic regression analysis were performed to evaluate the risk factors for OME in children with adenoid hypertrophy., Conclusion: A total of 166 children with adenoid hypertrophy were included; the incidence of OME in children with adenoid hypertrophy was 34.94%. The incidence of OME decreased significantly with the increase in age (p = 0.014). Logistic regression analysis showed that age < 3 years (OR = 3.149, 95%CI: 2.812-3.807) and duration of adenoid hypertrophy ≥12 months (OR = 2.326, 95%CI: 2.066-2.612) were the risk factors of OME in children with adenoid hypertrophy (all p < 0.05)., Patient Contribution: The incidence of adenoid hypertrophy with OME is high in preschool children, and it is related to the age and duration of adenoid hypertrophy., (© 2024 The Authors.

Background: Predisposing factors for otitis media with effusion are multifactorial, ranging from genetic and anatomical abnormalities to environmental factors and inflammation of the nose and adjacent structures., Aim: The study determined the risk factors for otitis media with effusion (OME) among children in Calabar Municipality., Methods: This was a descriptive, cross-sectional, community-based study including children aged 1-10 years randomly selected from government and privately owned daycares, nurseries (preschool), and primary schools. The risk factors assessed included upper respiratory tract infection, allergic rhinitis, adenoid enlargement, acute otitis media, recurrent acute otitis media parental educational level, overcrowding (four children sleeping in a room), duration of breastfeeding, cleft palate, and Down's syndrome. Allergic rhinitis was diagnosed when a child had at least two of the rhinological symptoms: nasal congestion, running nose, sneezing, itching of the eye or nose, and at least one of the following: history of allergy, family history of allergy, and positive history of asthma. The questionnaire was the research instrument used to assess the risk factors for OME. OME diagnosis was made with otoscopy and tympanometry. Data were collected and analyzed with IBM SPSS version 25, and a P value <0.05 was considered statistically significant., Results: A total of 24 daycare pupils, 141 nursery pupils, and 155 primary pupils were recruited into the study. The prevalence of otitis media with effusion was more in younger children than in older children and the relationship was statistically significant (P < 0.001). Female children were more statistically affected than male children (P = 0.007). Children with allergic rhinitis accounted for a higher proportion of those with OME than those without allergic rhinitis (26.7% vs. 11.6%), and the difference was statistically significant (P = 0.007). The association between OME and upper respiratory tract infection, acute otitis media, and recurrent acute otitis media was not statistically significant (P > 0.05). Multivariate binary logistic regression was used to identify predictors for the otitis media with effusion., Conclusion: There are many endogenous and exogenous risk factors for OME, but notable risk factors in our study were age 1-2 years, female sex, and allergic rhinitis., (Copyright © 2024 Copyright: © 2024 Nigerian Journal of Clinical Practice.)

Within the constantly changing landscape of the coronavirus disease 2019 (COVID-19) pandemic, the emergence of new variants introduces novel clinical challenges, necessitating the acquisition of updated insights into their impacts on various health conditions. This study investigates the clinical features and therapeutic outcomes of otitis media with effusion (OME) in adults following infection with the Omicron variant of COVID-19, in the context of China ending its "Zero-COVID-19" policy. Conducted as a multicenter, retrospective analysis at two medical institutions in Eastern China from December 2022 to February 2023, the study included patients with confirmed Omicron infection who were diagnosed with OME within two months, adhering to guidelines from the American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF). Data on demographics, time from infection to OME manifestation, associated symptoms, and treatment outcomes were collected. Among 68 patients (73 affected ears) with OME post-Omicron infection, common symptoms included cough and nasal obstruction (69.1%). All reported ear fullness, with 86.8% experiencing hearing loss. Tympanic bullae were observed in 72.6% during otoscopy, and most tympanometry results showed a B-type tympanogram (80.0%). An integrated treatment strategy led to an 83.6% cure rate, although 8.2% experienced relapse within 2-3 months. Our findings highlight OME as a prevalent ear complication associated with COVID-19 during the Omicron pandemic, underscoring the necessity for further investigation into its complexities. While the integrated treatment approach proved effective, the 8.2% post-treatment recurrence rate underscores the importance of ongoing monitoring and signals an urgent need for more comprehensive research.

Background: This study examined the epidemiological correlations between secretory otitis media (SOM) and diseases of neighboring organs. We measured changes in disease incidences during the 2020 COVID-19 pandemic using Internet big data spanning from 2011 to 2021., Methods: This study used the Baidu Index (BI) to determine the search volume for the terms "secretory otitis media (SOM)", "tonsillitis", "pharyngolaryngitis", "adenoid hypertrophy (AH)", "nasopharyngeal carcinoma (NPC)", "nasal septum deviation (NSD)", "rhinosinusitis", "allergic rhinitis (AR)", and "gastroesophageal reflux disease (GERD)" in Mandarin from January 2011 to December 2021. The correlations between these terms were analyzed using Spearman's correlation coefficients. The results were compared search data from 2019 and 2021 to assess the effects of isolation on SOM in 2020., Results: The seasonal variations trends of SOM and other diseases coincided well ( P  < 0.05), except for AR. During the 11-year timeframe, the monthly searches for rhinosinusitis, NSD, tonsillitis, pharyngolaryngitis, and NPC were statistically correlated with SOM ( R  = 0.825, 0.594, 0.650, 0.636, 0.664, respectively; P  < 0.05). No correlation was found between SOM and AR, SOM and AH, or SOM and GERD ( R  =  - 0.028, R  = 0.259, R  = 0.014, respectively, P  > 0.05). The total search volumes for SOM, rhinosinusitis, NPC, and AH decreased in 2020 compared to 2019., Discussion: SOM exhibited a discernible epidemiological connection with rhinosinusitis, nasal septal deviation (NSD), tonsillitis, pharyngolaryngitis, and nasopharyngeal carcinoma (NPC). A decrease in public gatherings was observed to effectively reduce the incidences of SOM. This underscores the pivotal role of social measures in influencing the prevalence of SOM and emphasizes the intricate interplay between SOM and various associated health factors, with implications for public health strategies., Competing Interests: The authors declare there are no competing interests., (©2024 Guo et al.)

Objective: Otolaryngologists perform bilateral myringotomy and tube placement for surgical management for otitis media with effusion. This retrospective study aimed to address the extent to which the coronavirus disease 2019 pandemic and season impact the number of bilateral myringotomy and tube placement procedures performed at a tertiary care centre., Methods: A total of 1248 charts of children who underwent bilateral myringotomy and tube placement from January 2018 through February 2021 were reviewed., Results: The cohort included 41.6 per cent females and 58.4 per cent males, with 63.7 per cent having private insurance. The median age at surgery was 2.6 years. The spring season had the most bilateral myringotomy and tube placement procedures per week. The number of bilateral myringotomy and tube placement procedures performed per week after the onset of the coronavirus disease 2019 pandemic was significantly lower compared to the years prior. There was no difference in number of intra-operative effusions pre-pandemic versus after the pandemic onset., Conclusion: This study sheds light on the impact of the coronavirus disease 2019 pandemic and seasonality on the rates of tympanostomy tube procedures, vital for understanding the temporality of ear infections.

Objectives: Otitis media with effusion (OME) is common, affecting up to 90% of children. Around 25% will have a persistent effusion with conductive hearing loss which can impact their development. Ventilation tubes (VTs) can improve their hearing in the short term. This study aims to analyse the trends in VT insertion rates across Scotland., Design: Retrospective observational study., Setting: All mainland Scottish health boards., Participants: All children aged 0-16 who underwent a VT insertion procedure from 2001 to 2018 were included., Main Outcome Measures: Data were provided by the Scottish Public Health Observatory, using Scottish Morbidity Records. Mid-year population estimates were obtained from the National Records Office of Scotland. Socioeconomic deprivation was estimated based on area of residence using the Scottish Index of Multiple Deprivation. VT insertion rates were calculated and trends analysed., Results: A total of 35 878 VT procedures were performed in total with a mean rate of 2.02 per 1000 children per year. The highest insertion rates were observed in children aged 4-6. VT insertion rates reduced during the study period (R = -0.729, p = .001). Variability in VT insertion rates between health boards reduced. There was a significant association between socioeconomic deprivation and VT insertion rate, with the most deprived children having the highest rate (p < .001)., Conclusions: VT insertion rates and the variability between Scottish health boards have reduced over the past two decades, suggesting a more equitable system. Our data intimates that the decision to perform VT insertion is based upon disease prevalence rather than clinician preference., (© 2023 John Wiley & Sons Ltd.)

Objective: The purpose of this study is to compare patient trends in otitis media with effusion (OME) symptoms and diagnoses before and after the COVID-19 pandemic in order to investigate the effects of the coronavirus disease of 2019 (COVID-19)., Methods: A retrospective, multi-center, observational study was carried out between January 2018 and December 2022 at hospitals in the Iwate Prefecture with full-time doctors. All patients were initially separated into two groups, one for the pre-COVID-19 era (from January 2018 to June 2020), and the other for the COVID-19 era (from July 2020 to December 2022)., Results: In the pre-COVID-19 era, 132 patients had tympanostomy tubes (TT) placed, while 64 patients had them placed in the COVID-19 era. Between the pre-COVID-19 and COVID-19 eras, there were no statistically significant differences in terms of age, sex, side, craniofacial deformity, or adenoidectomy. Children in elementary school showed a greater decline than those in preschool (42-11 patients in elementary school (74%) and 49 to 32 patients in preschool school (35%); p = 0.025)., Conclusions: The percentage of TT placements for OME dropped to roughly half during the COVID-19 epidemic. This was particularly obvious in elementary school students., Competing Interests: Declaration of competing interest All authors state no conflict of interest.

Purpose: We aimed to identify the role of bacterial biofilms in the chronicity of otitis media with effusion and its resistance to antibiotics. We illustrated this role by reviewing, analyzing, and correlating the findings with the results of the included studies to reach clear evidence., Methods: A comprehensive search of electronic databases (Scopus, PubMed, Web of Science, Cochrane, and GHL databases) was performed for all studies using the following strategy till April 2021 with the search terms: Biofilm and Middle ear effusion. We found 935 references, 421 were duplicates, and 514 were needed for further screening, and it was as follows: PubMed 215, Scopus 18, Cochrane 130, Web of Science 136, and GHL 15., Results: The pooled prevalence of culture-positive effusions was estimated to be 40% (95% CI [28%, 53%]) of the total OME population. Overall, the prevalence of PCR-positive effusions was estimated to be 97% (95% CI [95%, 99%]) of the total OME population. The pooled prevalence of EM-positive effusions was estimated to be 82% (95% CI [69%, 95%]) of the total OME population., Conclusion: The data presented in this study coincide with the significant role of bacterial biofilms in the pathogenesis of chronic otitis media with effusion. The involvement of bacterial biofilm as a component of the OME pathogenic process can help us to explain why antimicrobial therapy is not always effective in the eradication of the disease process and, also explain the recurrence of middle ear effusion after treatment with tympanostomy tubes either with or without adenoidectomy., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objectives: The purpose of this study was to investigate the fluctuations in the prevalence of individuals diagnosed with otitis media with effusion (OME) during the SARS-CoV-2 pandemic, while also evaluating the persistence of SARS-CoV-2 in middle ear effusion (MEE) and assessing the effectiveness of tympanocentesis as a treatment modality for OME in this specific period., Methods: The total number of outpatients and patients diagnosed with OME in our department was recorded for January 2022 and January 2023. Thirty patients (aged 15-86 years) were categorized into two groups: group A (n = 12), who developed OME during their SARS-CoV-2 infection and group B (n = 18), who experienced OME after the resolution of SARS-CoV-2 infection. All patients underwent otoendoscopic tympanocentesis (without a ventilation tube), where MEE and nasopharyngeal secretions were simultaneously collected for SARS-CoV-2 detection by polymerase chain reaction. The time interval from SARS-CoV-2 infection to tympanocentesis, results of SARS-CoV-2 detection, preoperative and postoperative average hearing threshold, and Eustachian Tube Dysfunction Questionnaire (ETDQ-7) scores were documented., Results: The proportion of outpatients with OME in January 2023 was higher than that in January 2022. There were five patients who had positive test results for SARS-CoV-2 on MEE after tympanocentesis. These 5 patients underwent tympanocentesis at a mean of 28 ± 7.28 days following confirmation of SARS-CoV-2 infection. The ETDQ-7 scores of group A exhibited a reduction from 21.85 ± 4.8 to 10.00 ± 4.07 following tympanocentesis, while the ETDQ-7 scores of group B also demonstrated a decrease from 21.22 ± 4.65 to 10.11 ± 3.68 after undergoing tympanocentesis. The tympanocentesis was effective in both groups., Conclusions: The study confirmed that the proportion of outpatients with OME in the Clinics of Otolaryngology during the SARS-CoV-2 epidemic increased significantly. SARS-CoV-2 RNA was detectable in MEE of COVID-19-related OME patients. Tympanocentesis was therapeutic for OME during SARS-CoV-2 infection, which facilitated viral clearance in MEE., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: To assess the effect of the coronavirus disease 2019 pandemic on paediatric bilateral myringotomy and tube insertion rates in New Brunswick, Canada., Methods: All paediatric bilateral myringotomy and tube insertion cases from 1 July 2015 through 30 June 2021 were provided by New Brunswick Medicare. The numbers of otolaryngologists, cataract surgical procedures, total hip arthroplasties and thyroidectomies were collected to assess the availability of operating theatres and otolaryngologists. Negative binomial logarithmic regressions were used for analyses., Results: Of the 5175 paediatric bilateral myringotomy and tube insertion cases that were included, the bilateral myringotomy and tube insertion rate significantly decreased by 2.9 times ( p < 0.001) during the pandemic. Thyroidectomies, cataract surgical procedures and total hip arthroplasties did not significantly decrease. The number of otolaryngologists increased (20 vs 16-17)., Conclusion: Paediatric bilateral myringotomy and tube insertion rates significantly decreased during the pandemic. This cannot be accounted for by reduced otolaryngologists or operating theatre availability. The paediatric bilateral myringotomy and tube insertion rate decrease is likely due to public health measures reducing the transmission of upper respiratory tract infections, resulting in fewer indications for paediatric bilateral myringotomy and tube insertion.

Cleft palate is associated with a high prevalence of middle ear dysfunction, even after palatal repair. The aim of this study was to evaluate the effects of robot-enhanced soft palate closure on middle ear functioning. This retrospective study compared two patient groups after soft palate closure with a modified Furlow double-opposing Z-palatoplasty technique. Dissection of the palatal musculature was performed using a da Vinci robot in one group and manually in the other. Outcome parameters were otitis media with effusion (OME), tympanostomy tube use, and hearing loss during 2 years of follow-up. At 2 years post-surgery, the percentage of children with OME had reduced significantly to 30% in the manual group and 10% in the robot group. The need for ventilation tubes (VTs) decreased significantly over time, with fewer children in the robot group (41%) than those in the manual group (91%) needing new VTs during postoperative follow-up (P = 0.026). The number of children presenting without OME and VTs increased significantly over time, with a faster increase in the robot group at 1 year post-surgery (P = 0.009). Regarding hearing loss, significantly lower hearing thresholds were recorded in the robot group from 7 to 18 months postoperatively. To conclude, beneficial effects of robot-enhanced surgery were recorded, suggesting a faster recovery when the soft palate was reconstructed using the da Vinci robot., (Copyright © 2023 International Association of Oral and Maxillofacial Surgeons.

Purpose of Review: In the clinical practice, patients affected by chronic rhinosinusitis (CRS) commonly complain of otologic symptoms. This review aims to describe the available literature evidence assessing the relationship between CRS and ear illnesses published in the last 5 years., Recent Findings: Available evidence suggests a higher prevalence of otologic symptoms in patients suffering from CRS, affecting up to 87% of patients. These symptoms may be related to Eustachian tube dysfunction, which improves after treatment for CRS. A few studies suggested a potential but not confirmed role of CRS in cholesteatoma, chronic otitis media, and sensorineural hypoacusis. A special type of otitis media with effusion (OME) may occur in patients with CRS, which seems to respond well to new biologic therapy. Ear symptoms appear to be highly prevalent in patients with CRS. So far, the available evidence is robust only for Eustachian tube dysfunction, which has been shown to be particularly impaired in CRS patients. Additionally, the Eustachian tube function appears to improve after treatment for CRS. Finally, interesting preliminary data were described for eosinophilic otitis media, as it appears to respond well to the treatment with biologics., (© 2023.

Objective: The aim of this study was to investigate the correlation between obstructive sleep apnea (OSA) and otitis media with effusion (OME) in Chinese children and identify risk factors for OME to support the development of standardized diagnostic and treatment methods., Patients and Methods: Clinical data of 1,021 children with OSA admitted to our hospital between January 2019 and December 2020 were collected. The prevalence of OME was assessed based on age groups and different grades of adenoid hypertrophy (AH). Multivariate logistic regression was performed to determine risk factors for OME in this population., Results: Among the patients, only 73 (6.15%) reported hearing loss as the main complaint, while 178 (17.43%) were diagnosed with OME after the examination. Acoustic immittance showed higher detection rates for OME compared to those of otoscopy and pure tone audiometry. In addition, the incidence of OME did not increase with AH grade but was higher in children with OSA with AH grade IV. Multivariate regression analysis showed that the younger age group (2-5 years), AH grade IV, nasal inflammatory disease, and passive smoking were significant risk factors for OSA and OME. However, sex, age of 6-12 years, and presence of chronic tonsillitis/tonsillar hypertrophy had no significant impact on the prevalence of OME., Conclusions: OME is highly prevalent in children with OSA. Clinicians should be vigilant in diagnosing OME, should conduct routine audiological examinations, and actively screen for middle ear fluid in all children with OSA, especially in younger children (2-5 years) with nasal mucosa inflammation and a history of passive smoking. This will help improve the detection rate of OME, as early intervention is paramount for preventing complications.

Background: In our practice as ENT specialists, people living with Human immunodeficiency Virus/acquired immunodeficiency syndrome (HIV/AIDS) have presented at the clinics with symptoms suggestive of otitis media with effusion such as the sensation of fluid in the ear, aural fullness and hearing loss. Eustachian tube dysfunction which is often the beginning of middle ear pathology could be caused by nasal allergy, upper respiratory tract infection, or obstruction by a nasal pharyngeal lesion such as lymphoid hyperplasia which is a common feature in people living with HIV/AIDS. Tympanometric findings give a measure of the objective assessment of middle ear function., Aim and Objective: This study was designed to determine tympanometric findings among adult patients undergoing short-term treatment with HAART in Port Harcourt., Patients and Methods: A hospital-based study involving 150 HIV-positive patients that received the same HAART treatment over 6 months and a control group of 150 HIV-negative individuals in Port Harcourt. The data extracted includes; the patient's ear symptoms, otoscopic findings, and tympanogram. Data were analyzed using SPSS version 20 and statistical significance was set at P > 0.05., Results: There was a high proportion of type B-Typanogram at baseline (Rt ear 24[16.0%], left ear 23 [15.3%]) and at repeat (Rt ear 23 (15.3%), Lt ear 21 (14%) evaluations. Also, there was a relatively high proportion of type C- tympanogram at baseline {right ear 18 (12%), left ear 15 (10%)} and at repeat Rt ear 14 (9.3%), Lt ear 10 (6.7%)} evaluations., Conclusion: One out of every eight patients living with HIV infection may likely have Eustachian tube dysfunction while one out of every five may have developed otitis media with effusion already. There was no significant change in tympanometric findings after treatment with HAART., Competing Interests: None

Otitis media with effusion (OME) is a type of otitis media (OM) characterized by the presence of fluid behind intact tympanic membrane and is one of the most common diseases of early childhood. It is an infectious disease associated with the presence of many pathogenic bacteria in the middle ear of affected individuals. This study was aimed to determine the prevalence of Gram-positive bacteria from the middle ear of OME patients in the population of Southern Punjab, Pakistan. The incidence of OME under comprehensive healthcare setting was investigated in patients who consulted at the department of ear, throat and nose, Bahawal Victoria Hospital (BVH), Bahawalpur, from December, 2019 to May, 2021. Ear swabs were taken from affected and normal individuals. After culturing bacteria from the ear swabs, microscopic analysis and biochemical tests were performed to characterize the cultured Gram-positive bacteria. Out of 352 patients examined, 109 (30.9%) patients had OME. Age of the participants ranged from 14 to 50 years; individuals between the ages of 14 and 22 years had the highest infection rates, while individuals between 40 and 50 years had the lowest rate of infection. Tympanic membrane perforation, fever, cough, sore throat, ear pain and hearing problem showed association with symptoms of OME. Microscopic analysis and biochemical characterization showed the presence of streptococci and staphylococci in all the studied samples. The most frequently isolated bacteria were Streptococcus pneumoniae, Streptococcus pyogenes, and Staphylococcus aureus with percentage of 53.3%, 20% and 13.3% respectively. Enterococcus faecalis (6.6%) and Staphylococcus epidermidis (6.6%) were also identified in the studied samples. This study will help in the better medical administration of OME affected individuals.

Background: Allergic rhinitis (AR) is a multifocal IgE-mediated type I hypersensitivity reaction involving nasal mucosa characterized by excessive sneezing, watery rhinorrhea, nasal itching, nasal stuffiness, and eyes itching. Tympanometry is a simple, rapid, and objective test that can be easily carried out. The use of tympanometry in clinical setting can improve detection of middle ear effusion and other middle ear abnormalities. AR has been found to be one of the predisposing factors to developing Otitis Media with Effusion (OME) in children., Patients and Methods: A case-control study was used to determine the prevalence of OME among children with AR as cases and those without allergy as controls. The study participants were children aged 4-12 years with clinical diagnosis of AR attending ENT clinics of Aminu Kano Teaching Hospital, whereas controls were children age 4-12 years without history of AR, ear diseases, or other respiratory system related ailments attending general outpatient clinics in Aminu Kano Teaching Hospital. An interviewer-administered score for AR (SFAR) questionnaire was filled out for all the participants, those with score of 6 and above were selected as cases. The two groups had complete ENT examination and tympanometry done, findings were recorded, and analyzed using SPSS version 21., Results: The mean age of the cases was 6.8 ± 2.1 years, whereas it was 7.5 ± 2.6 years for the controls. The mean difference was 0.7 and was not statistically significant (t = 2.35, df = 258, P value = 0.20). Type B tympanogram suggesting OME was found in 7.3% of subjects and in 2.8% of controls. Type C tympanogram suggesting negative middle ear pressure was found in 15.5% of subjects and in 4.6% of controls. Type A tympanogram suggesting normal middle ear pressure was found in 75% of subjects and in 90% of controls. Acoustic reflex was found to be absent in 29.6% of subjects and in 15.4% of controls and this found to be statistically significant (χ 2 = 7.77, df = 1, P value = 0.001). The difference between type A, B, and C tympanograms of subjects and that of controls was found to be statistically significant (Type A χ 2 = 14.62, df = 4, P value = 0.01, Type B χ 2 = 14.06, df = 4, P value = 0.01, Type C χ 2 = 17.01, df = 6, P value = 0.01). Type B tympanogram was used as an indicator to suggest OME for the purpose of this study., Conclusion: Participants with AR were found to have more abnormalities of tympanometric parameters and higher prevalence of type B tympanogram suggesting OME than controls., Competing Interests: None

The aim of this study was to investigate the relationship between obesity and otitis media with effusion. 471 cases with ages between 4 and 12 years were included. Of the 471 cases, 204 cases (97 girls, 107 boys) were diagnosed OME, the study group, 267cases (127 girls, 140 boys) were the control group. Body mass index of the two groups were compared to each other. The average body mass index for girls in all age groups was 17.93 ± 1.92 (n: 97) for cases with OME and 16.67 ± 1.28 (n: 127) for the control group.(p < 0.05). The average BMI for boys in all age groups was 18.25 ± 1.98 (n: 107) for cases with OME and 16.30 ± 1.26 (n: 140) for the control group. (p < 0.05). Children with a BMI greater than or equal to the 85th percentile were considered to be overweight or obese. Regarding the girls, of the 97 cases with OME, 23 cases were overweight, whereas of the 127 control cases, 7 cases were found to be overweight. This difference was statistically significant (p < 0.05). Regarding the boys, of the 107 cases with OME, 29 cases were overweight, whereas of the 140 control cases, 13 cases were found to be overweight. This difference was also statistically significant (p < 0.05). It is concluded that childhood obesity and overweight may play a role as a predisposing factor in the development of OME. It is also noted that even if a child is in the normal range of BMI percentile (less than 85th percentile; not obese or overweight), as the BMI increases, the relative risk of developing OME increases., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier B.V.

Objective:  Multiple, breeding-related malformations of the skull of brachycephalic dogs are well-known. Whereas the eye-catching deformities of the nose that lead to dramatic respiratory problems are obvious, changes of the middle ear are often an incidental finding on CT examinations and usually clinically inapparent. The objectives of this work were to investigate the prevalence and characteristics of middle ear effusion in brachycephalic dog breeds presented for multilevel surgery of upper airway obstructions., Material and Methods:  Brachycephalic dogs with incidental middle ear effusion detected on CT scans obtained prior to surgical treatment of brachycephalic airway syndrome were prospectively enrolled. A perendoscopic tympanocentesis followed by macroscopic description, microscopic cytology and bacteriological analysis of the fluid was performed., Results:  Prevalence of middle ear effusion in all dogs presented to the department during the study period was 55/170 (32 %) in 86 middle ears. The only breeds suffering from MEE were French Bulldogs (FB) with a prevalence of 35/66 (53 %) and Pugs with a prevalence of 20/79 (25 %). Tympanocentesis was performed in 80 ears. In the majority of cases the effusion was either mucoid or serous, with a honey-like or ochre colour.Bacteriology was available for 76 ears and tested positive in 34 (45 %) cases. Cytology was performed in 73 ears and revealed all effusions to contain inflammatory cells with a high concentration in 23 (31.5 %) cases., Conclusions and Clinical Relevance:  Brachycephalic dogs presented for surgical treatment of brachycephalic airway syndrome have a high prevalence of incidental middle ear effusions. Cytological findings differ from previously reported analyses of effusions in Cavalier King Charles spaniels with clinical symptoms of primary secretory otitis media, where usually cell-free effusions are found. A study comparing effusions of brachycephalic dogs with vestibular disease to those found as an incidental condition is warranted., Competing Interests: Disclosure The authors report no conflicts of interest in this work., (Thieme.

Objective: Identify the risk factors for otitis media with effusion (OME), especially laryngopharyngeal reflux (LPR), adenoid hypertrophy and allergic rhinitis, that could be used to develop prevention strategies in children., Design: A comparative cross-sectional study was conducted to make sure the adequacy of proportions of OME and non-OME cases in finding the related factors., Setting: History taking, ear/nose/throat (ENT) examination, and tympanometry were performed in preschool and elementary schools. Flexible fibreoptic nasopharyngolaryngoscopy was performed in a bronchoesophagology outpatient clinic in a tertiary referral hospital in Jakarta, Indonesia., Participants: Preschool and elementary children in East Jakarta, Indonesia were recruited for this study. A total of 2016 participants underwent history taking, ENT examination and tympanometry. The case group was 46 children with OME, and the control group was 46 children without OME. The number of subjects fulfilled the minimum sample size for two proportions comparison., Main Outcome Measures: A type B tympanogram indicated OME. A Reflux Finding Score of more than 7 indicated LPR. Adenoid hypertrophy was diagnosed using flexible fibreoptic nasopharyngolaryngoscopy. Allergic rhinitis was diagnosed using a questionnaire based on the International Study of Asthma and Allergies in Childhood phase III that has been validated for Indonesians., Results: The proportion of LPR in the OME group was significantly higher than in the non-OME group, at 78.3% and 52.2%. The probability of OME occurrence in patients with LPR was 3.3 times higher than in patients without LPR (OR 3.3; 95% CI 1.33 to 8.189; p=0.01). There was no significant relationship between adenoid hypertrophy and OME (p=0.211; 95% CI 0.71 to 3.97), and also between allergic rhinitis and OME (p=0.463; 95% CI 0.61 to 4.28)., Conclusion: The probability of OME occurrence in patients with LPR was 3.3 times higher than in patients without LPR. LPR should be considered in patients with OME and vice versa., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022. Re-use permitted under CC BY-NC.

Purpose: Otitis media with effusion (OME) is common in young children and is associated with Streptococcus pneumoniae infection. We aimed to determine the impact of pneumococcal conjugate vaccine (PCV) introduction on the prevalence of OME and OME associated with vaccine-type (VT) or non-VT., Methods: Population-based cross-sectional surveys were conducted in pre- (2016) and post-PCV periods (2017, 2018, and 2019) at selected communes in Nha Trang, Vietnam. For each survey, we randomly selected 60 children aged 4-11 months and 60 aged 14-23 months from each commune. Nasopharyngeal sample collection and tympanic membrane examination by digital otoscope were performed. S. pneumoniae was detected and serotyped by lytA qPCR and microarray. Odds ratios (OR) and 95% confidence intervals (CIs) were calculated using Firth's logistic regression, stratified by age group., Results: Over the four surveys, 2089 children had a bilateral ear examination. Compared to pre-PCV, the prevalence of OME reduced in 2018 (OR 0.51, 95 %CI 0.28-0.93) and in 2019 (OR 0.53, 95 %CI 0.29-0.97) among the <12-month-olds, but no significant reduction among the 12-23-month-olds. The prevalence of OME associated with VT pneumococcus decreased in 2018 and 2019 (2018: OR 0.14, 95 %CI 0.03-0.55; 2019: OR 0.20, 95 %CI 0.05-0.69 in the <12-months-olds, 2018: OR 0.05, 95 %CI 0.00-0.44, 2019: OR 0.41, 95 %CI 0.10-1.61 in the 12-23-months-olds). The prevalence of OME associated with non-VT pneumococcus increased in the 12-23-month-olds in 2017 (OR 3.09, 95 %CI 1.47-7.45) and returned to the pre-PCV level of prevalence in 2018 and 2019 (OR 0.94, 95 %CI 0.40-2.43 and 1.40, 95 %CI 0.63-3.49)., Conclusion: PCV10 introduction was associated with a reduction of OME prevalence in infants but not in older children., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: [Catherine Satzke and Kim Mulholland are investigators on a Merck Investigator Studies Program grant funded by MSD on pneumococcal serotype epidemiology in children with empyema and a clinical research collaboration on PCV vaccination in Mongolia funded by Pfizer.

Objectives: Atelectatic eardrum and adhesive otitis media in children are related to persistent otitis media with effusion (OME) and eustachian tube dysfunction in infancy. However, the pathogenesis of these diseases is not fully understood, and some cases even progress to pars tensa cholesteatoma. This study analyzed the clinical characteristics of children with atelectatic eardrum and adhesive otitis media to clarify associated causes of and risk factors for progression of these middle ear pathologies in children., Patients and Methods: This retroactive study included 38 ears of 31 children with atelectatic eardrums (atelectasis group), and 19 ears of 17 children with adhesive otitis media (adhesive OM group). Thirty-two contralateral non-cholesteatoma ears of 32 children with congenital cholesteatoma were also examined as a control group. Participants were aged 15 or younger. Life history (obtained via questionnaire), associated diseases, hearing acuity, aeration and development of the temporal bone were investigated., Results: All children in the atelectasis and adhesive OM groups had a history of recurrent acute otitis media (rAOM) and/or OME. The prevalence of perennial allergic rhinitis was 18 cases (58%) in the atelectasis group and 16 cases (94%) in the adhesive OM group. The prevalence of perennial allergic rhinitis was significantly higher in the adhesive OM group compared to the control group (P < 0.01). The development of mastoid air cells, categorized by MC classification, showed MC0 + MC1 (poor pneumatization) in 19 ears (50.0%) with atelectatic eardrums and 12 ears (63.2%) with adhesive OM. Poor pneumatized mastoid was more frequently observed in the ears of the atelectasis and adhesive OM groups compared to the control group (P < 0.01). No significant difference was found in regards to aeration of the middle ear between the two groups; however, aeration was significantly poorer in both groups compared to the control group (P < 0.01). Three characteristics were analyzed using multivariate logistic regression: perennial allergic rhinitis (odds ratio [OR] 4.319, P = 0.013), poor mastoid pneumatization (OR 8.457, P = 0.012), and pars flaccida retraction pocket (OR 20.897, P = 0.006). These characteristics were shown to be significant risk factors for atelectatic eardrums and adhesive OM. In addition, the predisposition to perennial allergic rhinitis was shown to be the most important factor in the progression from atelectatic eardrum to adhesive otitis media (OR 16.615, P = 0.012)., Conclusion: Children with perennial allergic rhinitis, poor development of mastoid air cells, poor aeration of the temporal bone, and with pars flaccida retraction pocket were at an increased risk of developing an atelectatic eardrum and adhesive OM. In particular, perennial allergic rhinitis was shown to be a significant risk factor in the progression from atelectatic eardrum to adhesive otitis media. Allergic inflammation may affect not only the nasal passages but also the eustachian tube, resulting in persistent middle ear dysfunction. Therefore, children with rAOM/OME who have these risk factors should be carefully monitored and treat over time in effort to prevent progression of pathology., (Copyright © 2022 Elsevier B.V.

Objectives: In the COVID-19 era, extreme measures of social distancing have contained the spread of common viral respiratory infections, which are involved in the pathogenesis of Adenotonsillar Hypertrophy (ATH), and Chronic Otitis Media with Effusion (COME), the two commonest chronic ENT diseases of childhood. This study examines the lockdown effect on the number of procedures performed for these two conditions., Methods: The consecutive charts of 650 and 195 children being operated respectively for ATH and COME during the quarantine (05/2020-02/2021) and unrestrained (05/2019-02/2020) periods were retrospectively reviewed. Surgical treatment of ankyloglossia, performed in 103 patients during the same periods was employed as a control procedure., Results: Adenotonsillectomies and tympanostomies significantly decreased in the lockdown phase by 52% (P < 0.001) and 74% (P < 0.001), respectively, whereas control procedure counts increased by 25%. In terms of seasonal variation, ATH-related surgeries were significantly reduced during the winter season of the pandemic by 73% (P < 0.001), in comparison with the corresponding months of the unrestrained period. School-aged children received significantly fewer operations for ATH (-59%) than preschoolers (-42%), as a result of the lockdown (P = 0.044)., Conclusion: When the child's exposure to respiratory pathogens is minimal, as in the case of lockdown, a noticeable decline occurs in the incidence of ATH and COME indicated for surgical treatment. Chronic low-grade inflammation, boosted by repetitive viral infections seems to underlie both conditions. Timely, effective isolation measures might reverse the disease process and keep the child away from the Operating Room., (Copyright © 2022 Elsevier B.V. All rights reserved.)

Background: Otitis media with effusion (OME) is common in children aged between 6 months to 4 years, and it is one of the causes of hearing loss (HL) in children worldwide. OME is a type of inflammation of the middle ear in which there is a collection of fluid. The latter causes HL which interferes with speech and language development, communication skills, school performance, psychosocial skills, and quality of life of children., Methods: This was a prospective cross-sectional study on 246 children aged 2 -12 years, attending the Mulago National Referral Hospital (MNRH). A consecutive sampling procedure was used to reach each participant under ethical considerations until the sample size was reached. All children aged 2-12 years who meet inclusion criteria were examined first by the Pediatrician and then by the Principal Investigator. Patients with tympanogram type B (flat curve) were diagnosed to have OME. The prevalence of OME was summarized as a proportion and multivariate analysis was used to determine the factors associated with OME. Data were analyzed using the STATA version 13.0., Results: A total of 246 children were recruited for the study. Of the 246 children, 60% were male. The median age of the participants was 4.8 ± 2.8 years. The prevalence of OME was found to be 11%. Upper respiratory tract infections (URTI), recurrent AOM (p = 0.005, OR:5.14, 95% CI: 1.66-15.96), and snoring (p = 0.000, OR: 6.32, 95% CI: 2.32-17.26) were found to be strongly associated with OME in children aged 2-12 years attending the Mulago National Referral Hospital., Conclusions: The prevalence of OME among children aged 2-12 years attending MNRH was found to be 11%. There is an association between OME and URTI, recurrent AOM, and snoring in children aged 2-12 years attending MNRH., (© 2022. The Author(s).)

Objectives: The objectives of this study were to: (1) determine the prevalence of otitis media with effusion in patients with nonsyndromic craniosynostosis; (2) determine the prevalence of hearing loss in patients with nonsyndromic craniosynostosis; and (3) identify potential patterns and outcomes in patients with nonsyndromic craniosynostosis., Methods: A retrospective chart review was conducted at 2 academic institutions, St Christopher's Hospital for Children and SUNY Upstate Medical University, from January 2015 through August 2018, to identify patients having nonsyndromic craniosynostosis with a concurrent diagnosis of otitis media and/or hearing loss. The demographic data and categorical variables were analyzed using descriptive statistics and chi-square testing, respectively., Results: In the entire cohort of patients (N = 113, age range 0-123 months), 36% had otitis media with effusion on either history, physical examination, tympanometry, and/or imaging. Half (50%) of patients with coronal synostosis had otitis media with effusion compared to sagittal (40.7%), metopic (26.3%), multiple (25%), and lambdoid (0%). However, these differences were not statistically significant ( P = .190). Most patients had normal hearing (91%), while a minority had either conductive (7%) or sensorineural (2%) hearing loss., Conclusion: The presence of otitis media in our cohort of patients with nonsyndromic craniosynostosis appears to be at the upper limit of normal when compared to historical rates in normocephalic children. Synostosis subtype did not appear to predict the presence of otitis media. Only 9% of patients with nonsyndromic craniosynostosis were found to have a hearing loss.

Objective: Cleft palate (CP) in children is frequently complicated by otitis media with effusion (OME) due to Eustachian tube dysfunction. Although tympanostomy tube (TT) placement can be beneficial in the treatment of OME to prevent short-term hearing loss, there is no consensus regarding the indications for and timing of TT insertion. The present study was performed to define the safety and effectiveness of simultaneous TT placement with palatoplasty during the language-acquisition period., Methods: We retrospectively reviewed the medical charts of pediatric patients who underwent palatoplasty for CP in a tertiary medical center, Kyoto University Hospital, from June 2010 to October 2018. The TT retention time was estimated using the Kaplan-Meier method. The incidence of OME recurrence was compared among four Veau classification groups based on the patients' sex, type of CP, median TT retention time, and type of fluid., Results: Seventy-six subjects (150 ears) were enrolled in the study. The median follow-up duration was 48.7 months (range, 18.2-108.0 months) after the first TT placement. A first TT retention time of <20.1 months was a significant risk factor for OME recurrence. Subjects with maxillofacial anomaly complex and subjects with cleft lip and palate and an alveolar cleft showed a significantly higher OME recurrence rate than subjects with clefts only in the hard and/or soft palate. There was no significant difference in the occurrence of sequelae between subjects with only a single TT placement and subjects with more than one TT placement., Conclusions: Based on the findings of the present study, it is reasonable to perform TT insertion at the same time as palatoplasty on patients who meet the indications. This technique may reduce the number of times the patient requires general anesthesia and maintain good middle ear condition during the period of language acquisition between 1 and 3 years of age., (Copyright © 2022 Elsevier B.V.

Otitis media with effusion (OME) is amongst the most common pediatric diseases and the most common cause of hearing loss in children. It is accepted that adenoid hypertrophy (AH) is related to OME incidence. Better understanding of the correlation between the relative size of AH and the incidence of persistent OME may provide evidence to support a more standardized approach to the diagnosis and treatment of OME. A retrospective study carried out between April 2016 and April 2018 collected data on 65 children aged 2-12 years, diagnosed with chronic OME and symptoms of AH, where conservative therapy failed. Pre-diagnostic data were collected from patient history, otoscopy, rhinoscopy, and oropharyngoscopy findings. Diagnostic workup included tympanometry, audiometry, and flexible nasal fiberoptic endoscopy. Adenoid grading was performed according to Cassano method after endoscopic visualization. Of the 65 patients, 37 were male and 28 were female. There was no statistically significant difference according to gender or average age. The highest incidence of persistent OME with AH was recorded in the youngest age groups (2-5 and 6-9 years). The most frequent AH grades were grade II (35.38%) and grade III (50.77%), yielding a statistically significant result. The most common presenting symptoms were hearing impairment, snoring, and nasal obstruction (100%, 64.62% and 60%, respectively). Higher AH grades are critical for persistence of OME and may cause conservative therapy failure.

Objective: To evaluate the role of social isolation during the lockdown due to the SARS-CoV-2 outbreak (severe acute respiratory syndrome coronavirus 2) in modifying the prevalence of otitis media with effusion (OME) and the natural history of chronic OME., Study Design: Retrospective study., Setting: Tertiary level referral audiologic center., Methods: We assessed the prevalence of OME among children aged 6 months to 12 years who attended the outpatient clinic for hearing or vestibular disorders during 2 periods before the lockdown, May-June 2019 (n = 350) and January-February 2020 (n = 366), and the period immediately after the lockdown, May-June 2020 (n = 216). We also compared the disease resolution rates between a subgroup of children with chronic OME (n = 30) who were diagnosed in summer 2019 and reevaluated in May-June 2020 and a similar subgroup (n = 29) assessed in 2018-2019., Results: The prevalence of OME in this clinic population was 40.6% in May-June 2019, 52.2% in January-February 2020, and 2.3% in May-June 2020. Children with chronic OME had a higher rate of disease resolution in May-June 2020 (93.3%) than those examined in May-June 2019 (20.7%, P < .001)., Conclusion: Closure of schools and the physical distancing rules were correlated with a reduction in the prevalence of OME and favored the resolution of its chronic forms among children who attended the outpatient clinic. These data could suggest that in the presence of chronic OME, keeping young children out of group care settings for a period might be beneficial to allow for OME resolution.

Objectives: Children with Down syndrome (DS) have a higher incidence of tympanostomy tube insertion (TTI) than children in the general population. As there were no studies investigating factors that are associated with multiple TTIs in children with DS, we sought to determine what factors increase or decrease the likelihood of repeat TTI in children with DS., Methods: A retrospective case-control study was performed on consecutive children with DS from 2007 to 2018 with first TTI at a large tertiary children's hospital and follow-up duration at least 27 months since first TTI., Results: 277 patients met the inclusion criteria. Repeat TTI rate was 61.4%. Having an indication of chronic otitis media with effusion (COME) at first TTI was an adjusted risk factor for increased rate of repeat TTI (OR: 2.01, 95%CI: 1.15-3.51, p = .014), while being older at first TTI was an adjusted protective factor for decreased rate of repeat TTI (OR: 0.84, 95%CI: 0.74-0.95, p = .004). Adenotonsillectomy at or before first TTI was not an adjusted protective factor for decreased rate of repeat TTI (OR: 0.915, 95%CI: 0.448-1.872, p = .809) and bilateral intra-operative fluid was not an adjusted risk factor for repeat TTI (OR: 1.97, 95%CI: 0.99-3.90, p = .054)., Conclusion: Children with DS were more likely to undergo repeat TTI if they were of younger age and if the indication for surgery was COME. The repeat TTI rate for children with DS was high at 61.4%. Prospective studies are warranted to more precisely investigate factors associated with repeat TTIs in this unique patient population., (Copyright © 2021 Elsevier B.V. All rights reserved.)

Objectives: To investigate the relationship between laryngopharyngeal reflux (LPR) and recurrent (ROM) or chronic otitis media with effusion (COME)., Databases: PubMed, Scopus, and Cochrane Library., Methods: Three authors searched articles published between January 1980 and September 2020 about the association between LPR and the development of recurrent or chronic otitis media. Inclusion, exclusion, diagnostic criteria, and clinical outcome evaluation of included studies were analyzed using PRISMA criteria. The bias analysis of included studies was evaluated with the Tool to assess Risk of Bias of the CLARITY group., Results: Twenty-six clinical and three experimental articles met our inclusion criteria, accounting for 1,624 children and 144 adults with COME or ROM. According to the pH study type, the prevalence of LPR and gastroesophageal reflux disease (GERD) in OM patients were 28.7% (range, 8-100%) and 40.7 (range, 18-64%), respectively. The majority of studies identified pepsin or pepsinogen in middle ear effusion, with a range of mean concentrations depending on the technique used to measure pepsin. There was an important heterogeneity between studies regarding definition of COME, ROM, and LPR, exclusion criteria, methods used to measure pepsin/pepsinogen in middle ear secretions and outcome assessments., Conclusion: The association between LPR and OM is still unclear. Future clinical and experimental studies are needed to investigate the association between LPR and OM in both children and adults through extensive gastric content analysis in middle ear suppurations and impedance-pH monitoring considering acid, weakly acid, and alkaline reflux events., Competing Interests: The authors disclose no conflicts of interest., (Copyright © 2021, Otology & Neurotology, Inc.)

Background: Management of pediatric otitis media with effusion (OME) and recurrent otitis media typically includes observation up to 3 months. Bilateral myringotomy and tube (BMT) placement is performed due to persistent effusion with associated symptoms such as decreased hearing. With the COVID-19 pandemic and mandatory stay at home orders (MSHO), children were quarantined at home and many remained home after MSHO. We reviewed the prevalence of middle ear effusion (MEE) at the time of BMT during similar time periods in the year before, during and after MSHO in this pandemic year., Study Design: Retrospective summary of BMT cases at a single tertiary children's hospital., Methods: All children <18 years who underwent BMT between March 1, 2020 and July 1, 2020 and between March 1, 2019 and July 1, 2019 were included. Statistical analysis included chi-squared and Mann-Whitney U tests., Results: A total of 778 cases were reviewed; 551 (71%) were performed pre-pandemic and 227 (29%) during onset of pandemic (N = 778). There were no significant differences in gender, age, and BMI between groups, but significantly fewer Caucasians (58% vs. 45%, p < 0.05) and more Hispanics (20% vs. 33%, p < 0.05) during-COVID. The prevalence of intraoperative effusion during-COVID was significantly lower compared to pre-COVID (65% vs. 83%, p < 0.001)., Conclusion: Pandemic and COVID-19 MSHO were associated with significantly lower intraoperative OME prevalence. Further research may elucidate the impact of face covering, social distancing, and virtual schooling on the incidence of pediatric ROM, OME, and ENT symptoms., (Copyright © 2021 Elsevier B.V.

Background: Mucopolysaccharidoses (MPSs) are lysosomal storage disorders wherein glycosaminoglycans accumulate because the enzymes that degrade them are insufficient. The earliest symptoms, which are the main reasons for seeking consultation, are otorhinolaryngological and commonly occur in MPS I, II, IV, and VI. This retrospective study aimed to determine the occurrence of otorhinolaryngological manifestations in MPS patients in Taiwan and to analyze the prognosis of surgical intervention, including its effect on symptoms. Methods: We reviewed 42 patients (30 males and 12 females), with a median age of 20.5 years, who had MPS (16.7% type I, 35.7% type II, 19.0% type IIIB, 21.4% type IVA, and 7.2% type VI). The following otorhinolaryngological manifestations were collected: annual number of upper respiratory tract infections (URTIs) and otitis media with effusion (OME) episodes, adenoid size, tonsillar size, and apnea-hypopnea index (AHI). Results: Among 42 patients, we found recurrent otitis media in 42.9% of the patients, hearing loss in 83.3% (mixed: 52.4%, conductive: 21.4%, and sensorineural: 9.5%), frequent URTIs in 47.6%, and obstructive sleep apnea syndrome in 35.7%. Moreover, 76% of the patients underwent ear, nose, and throat (ENT) surgery, including adenoidectomy, tonsillectomy, tympanostomy with ventilation tube insertion, tracheotomy, and supraglottoplasty. Conclusions: MPS patients had a high incidence of ENT problems. ENT surgery reduced the severity of hearing loss, degree of symptoms related to upper airway obstruction, and severity of respiratory tract and otological infections of patients with MPS., Competing Interests: Competing Interests: The authors have declared that no competing interest exists., (© The author(s).)

Abstract: This study aimed to evaluate the risk of developing chronic otitis media with effusion (OME) in individuals with gastroesophageal reflux disease (GERD).A retrospective propensity score-matched cohort study was performed using data from the Korea National Health Insurance Service. The GERD group (n = 3532) included certain individuals who had been diagnosed with GERD between January 2002 and December 2005. A comparison control group (n = 14,128) was calculated by 1:4 Propensity Score (PS) matching considering age, sex, and comorbidities and year of enrolment. Each patient was monitored until 2013. Survival analysis, the log-rank test, and Cox proportional hazard regression models were used to calculate the incidence, survival rate, and hazard ratio (HR) of chronic OME for each group.Among the 17,660 individuals included in the study population (53.2% male), the overall incidence of chronic OME during the 11-year follow-up was 1.84-fold higher in the GERD group than in the non-GERD group (1.8 vs 3.0 per 1000 person-year; adjusted HR 1.84; 95% confidence interval [CI], 1.46-2.31). Moreover, the adjusted HRs of developing chronic OME (allergic rhinitis, 1.69 [95% CI, 1.37-2.10]; asthma, 1.29 [95% CI, 1.02-1.64]; chronic rhinosinusitis, 1.61 [95% CI, 1.26-2.05]) were greater in study population with comorbidities.From long-term follow-up, the prevalence of chronic OME in adults was 1.84 times higher in the GERD group compared with the non-GERD group. Specifically, it found that allergic rhinitis, asthma, or chronic rhinosinusitis showed increase the risk of developing chronic OME than those without these conditions., Competing Interests: The authors have no conflict of interest to disclose., (Copyright © 2021 the Author(s).

Purpose: Otitis media with effusion (OME) commonly occurs and persists in young children. It can cause hearing impairment and damage to the tympanic membrane without treatment. We aimed to determine the prevalence and association of Streptococcus pneumoniae in the nasopharynx of healthy children before the introduction of a pneumococcal conjugate vaccine., Methods: In October 2016, nasopharyngeal swabs collection and otoscope examinations by an otolaryngologist were conducted in children aged less than 24 months in Nha Trang, Vietnam. OME was diagnosed as the presence of middle ear fluid using a digital otoscope equipped with a pneumatic otoscope. Quantitative PCR targeting pneumococci-specific lytA (the major autolysis gene) and bacterial culture were performed to detect S. pneumoniae. The point prevalence of OME in the study area was estimated. The association between OME and S. pneumoniae in the nasopharynx was evaluated using a multivariable logistic regression model., Results: Among the 274 children who underwent bilateral ear examinations and nasopharyngeal swab collections, 47 had OME (17.2%, 95% confidence interval [CI] 12.9-22.1%) and 96 were colonized with S. pneumoniae (35.0%, 29.4-41.0%). OME and nasopharyngeal S. pneumoniae carriage were positively associated in children aged less than 12  months (adjusted odds ratio [aOR] 3.83, 1.40-10.51). Day-care attendance and living in a rural area were independently associated with OME (aOR 5.87, 2.31-14.91, and aOR 3.77, 1.58-8.99, respectively)., Conclusions: The nasopharyngeal pneumococcal carriage was associated with OME among children aged  <12 months. A further study after introducing a pneumococcal conjugate vaccine (PCV) is required to better understand the effect of PCV and S. pneumoniae carriage on OME in young children., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier Ltd.

Introduction: The prevalence of middle ear disease and its risk factors have been the subject of multiple studies. High prevalence of middle ear disease has been described among North American natives, especially chronic otitis media. Such studies have not been carried out in South America., Objective: To describe the prevalence of middle ear pathology and risk factors in native schoolchildren from southern Chile who belong to the Mapuche ethnic group, as well as the impact of socio-economic and demographic changes after 14 years of development., Material and Methods: Two otologic evaluations with an interval of 14 years were performed in schoolchildren with a percentage of indigenous population above 85%. Socioeconomic and demographic data were collected from national official statistical data., Results: A total of 1067 schoolchildren were examined. Many described risk factors for ear pathology were found. An overall prevalence of 0.19% for tympanic membrane perforation, 5.6% for pars tensa retraction pockets, 1.5% for pars flaccida retraction pockets and 11.1% of otitis media with effusion was found. There were several socioeconomic improvements after 14 years. The difference between the prevalence of symptoms and the presence of otitis media with effusion was statistically significant (p<0.001)., Conclusions: Despite the presence of several risk factors for middle ear disease, this study population showed a low prevalence of middle ear disease. The ethnic-racial factor seems to be a protective factor., (Copyright © 2021 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial. Published by Elsevier Editora Ltda.

Background: Otitis media with effusion (OME) is a known side effect of radiation therapy in patients with head and neck cancer., Aims/objectives: To investigate the incidence rate and clinical course of radiation-induced OME, we have reported on the long-term characteristics of OME in patients with parotid gland malignancy., Material and Methods: This cohort study assessed 200 patients who underwent post-parotidectomy radiation therapy from January 2010 to December 2019 in a tertiary referral center. Postoperative radiation therapy was performed at 6 weeks post-surgery. Serial magnetic resonance images were collected to detect otitis media. Two blinded otologists individually assessed data from radiation therapy initiation to 36 months of post-radiation therapy., Results: A total of 121 patients were enrolled (male, 61 [50.4%]; mean age, 46.98 ± 15.69 years), of which 14 developed otitis media (11.6%) within 6 months after radiation therapy. Spontaneous remission occurred without intervention within 1 year, excluding one patient who sustained otitis media for 2 years., Conclusions and Significance: Radiation-induced OME occurred in 11.6% of patients and it remitted within 1 year without intervention. Therefore, cooperation between otolaryngologists and radiation oncologists is required and invasive intervention should be considered with careful risk-benefit evaluation.

Objective: To compare the prevalence of middle ear abnormalities in pugs and in French bulldogs and evaluate the influence of nasopharyngeal dimensions on middle ear effusion., Study Design: Retrospective study., Animals: Thirty pugs and 30 French bulldogs with brachycephalic airway syndrome and no known history of ear disease., Methods: Computed tomographic (CT) studies were reviewed for middle ear effusion, mucosal contrast enhancement, signs of osteitis, and tympanic wall thickness. Soft palate thickness and cross-sectional areas of the nasopharynx at the opening of the auditory tube were measured and normalized to each individual's skull index before statistical comparison between breeds. Statistical dependence of middle ear abnormalities and nasopharyngeal dimensions was assessed by using Spearman's rank correlation tests., Results: Middle ear effusion was observed in 17 of 30 (56.7%) French bulldogs and five of 30 (16.7%) pugs. Contrast enhancement of the tympanic bulla was noted in 25 of 60 (41.6%) French bulldog ears and three of 60 (5.0%) pug ears. The cross-sectional airway dimensions (difference [Δ] = 0.31 cm 2 , P < .0001) and soft palate thickness (Δ = 0.44 cm, P < .0001) were reduced in pugs compared with in French bulldogs. Weak correlations were detected between soft palate thickness and nasopharyngeal dimensions and presence of tympanic bulla effusion (r = 0.324 and r = 0.198, respectively) or contrast enhancement (r = 0.270 and r = 0.199, respectively)., Conclusion: Middle ear effusion and inflammation were more common in French bulldogs than in pugs and did not seem related to nasopharyngeal dimensions., Clinical Significance: French bulldogs with brachycephalic airway syndrome seem predisposed to middle ear effusion and inflammation., (© 2021 The American College of Veterinary Surgeons.)

Objective: The aim of our study was to contribute to the literature about the prevalence of OME by conducting a research in a wide geography examining most of the associating factors together with a questionnaire. Additionally, possible effects of altitudes and latitudes, concordance between the otoscopic examination findings and tympanometric and acoustic reflex test results were evaluated in 4-7 years old children in the same season in different countries., Methods: In the randomly sampled schools from different regions of different cities where people of different scoioecomonic statuses live, 4-7 year-old children were included in the study. The results of the questionnaire covering the potential factors in OME etiology were evaluated together with the results of the otoscopic examination and tympanometry findings, and also the acoustic reflex findings to direct the interpretation in cases of low amplitude - blunted peak tympanograms which can be interpreted as a "Type B" or "Type As". All the results were gathered in the same season., Results: Ten centers from nine countries participated in the study. A total of 4768 children were evaluated. The frequency of OME diagnosed by otosopic examination was 22.48% (n=1072) and the diagnosis rate when otoscopic examination plus type B tympanometry were taken into account was found as 11.3% (n=539) in general population. Factors increasing the prevalence of OME were found as; mother's educational level (p=0.02), child's age (p=0.006), history of upper respiratory tract infection (p=0.001), smoking father (p=0.01), mother being a housewife or laborer (p=0.01), history of allergy (p=0.001), asthma (p=0.04), or allergy symptoms (p=0.02). No direct relationship was found between altitudes or latitudes and prevalence of OME., Conclusion: The important affecting factors found after analyzing all of the potential risk factors in the same model are secondhand smoke exposure, low level of mother's education, mother's occupation, positive history of URTI, and age of the child being less than 7. By paying attention to the factors that increase the prevalence of OME, putting particular emphasis on the preventable ones such as smoking, education, and fighting with allergies could decrease the prevalence of this public health issue., (Copyright © 2021 Elsevier B.V.

Objectives: To estimate the burden, and clinical factors associated with development of Otitis media with effusion (OME) in children with enlarged adenoids., Methods: Consecutive eligible patients with adenoid (sometimes with tonsillar) enlargement managed operatively in a period of five years. Patients had no complaints suggestive of hearing impairment. Age, sex, clinical diagnosis, and weight of patients were recorded. Otoscopic, audiometric, and radiological examinations findings were recorded. Tympanometry patterns were classified according to Jerger's classification; type B and C tympanograms represented OME. Some patients had Pure Tone Audiometry (PTA). Plain nasopharyngeal X-ray assessed the adenoid: nasopharyngeal (AN) ratio with >0.5 regarded as obstructive adenoid., Results: 216 ears of 108 children were assessed. 49.1% of children were in age range 1-3 years, mean 3.6 ± 2.6 years. 62.0% were males, weight ranged from 7.8 to 31.0 kg, mean was 14.3 ± 5.2 kg. 63.9% had associated tonsillar enlargement. Mean AN ratio was 0.69 ± 0.07. Tympanometric findings showed prevalence of OME in all ears was 63/216 = 29.2%, consisting of 30.5% with unilateral (Right ear 19.4%, Left ear 11.1%), and 13.9% with bilateral OME. Acoustic reflexes were absent in both ears in 32 (29.6%) of the patients. There was normal hearing in 16/38 ears (42.1%), while others had different types of hearing loss. Two factors namely increased age and weight were significantly associated with OME in patients with Adenoid enlargement., Conclusions: 29.2% of children with adenoid enlargement had a co-morbidity of asymptomatic OME. The factors associated with OME were increased age and weight of the patients., (Copyright © 2020 National Medical Association. Published by Elsevier Inc. All rights reserved.)

Background: Otitis media with effusion (OME) can cause serious complications such as hearing impairment or development delays. The aim of the study was to assess the microbiological profile of organisms responsible for OME and to determine if a biofilm formation can be observed., Methods: Ninety-nine samples from 76 patients aged from 6 months to 12 years were collected for microbiological and molecular studies., Results: In microbiological studies, pathogenic bacteria Haemophilus influenzae (38.89%), Streptococcus pneumoniae (33.33%), and Staphylococcus aureus MSSA (27.78%), as well as opportunistic bacteria Staphylococcus spp. (74.14%), Diphtheroids (20.69%), Streptococcus viridans (3.45%), and Neisseria spp. (1.72%) were found. The average degree of hearing loss in the group of children with positive bacterial culture was 35.9 dB, while in the group with negative bacterial culture it was 25.9 dB ( p = 0.0008). The type of cultured bacteria had a significant impact on the degree of hearing impairment in children ( p = 0.0192). In total, 37.5% of Staphylococcus spp. strains were able to form biofilm., Conclusions: Staphylococcus spp. in OME may form biofilms, which can explain the chronic character of the disease. Pathogenic and opportunistic bacteria may be involved in the etiopathogenesis of OME. The degree of hearing loss was significantly higher in patients from which the positive bacterial cultures were obtained.

Background: Insertion of middle ear ventilation tubes (MEVT), tympanostomy tubes or grommets is one of the most common paediatric surgical procedures performed by ENT surgeons worldwide. Outcomes may be complicated by postoperative otorrhoea and ventilation tube blockage., Objective: To identify risk factors associated with early postoperative complications of MEVT insertion., Method: In a case-control study, set in a tertiary hospital in Melbourne, Australia, 590 paediatric patients undergoing grommet insertion between February 2017 and February 2018, 311 patients (205 males & 106 females; median age of 3.86 years) met the inclusion criteria and had identical middle ear status bilaterally., Intervention: Tympanostomy tube insertion and postoperative topical otic antibiotic drops., Main Outcome and Measures: Patient age, gender, weight/BMI percentile, intraoperative middle ear status, number of previous grommets, type of surgery, season of surgery, diagnosis and time to first medical review were examined. The duration of topical otic antibiotic drops used and tube patency and presence of otorrhoea at 6-week postoperative review were also recorded., Results: At the first medical review, 8.7% of patients (n = 27) developed otorrhoea from one or both ears, 6.4% of patients (n = 20) had an obstructed MEVT in one or both ears. Exposure to intraoperative [IO] and postoperative [PO] antibiotic drops were significantly less associated with developing postoperative otorrhoea compared to non-exposure (IO: Odds Ratio [OR] = 0.15, 95%CI 0.04 to 0.57, p = 0.005; PO: OR = 0.21, 95%CI 0.58 to 0.76, p = 0.017). There were no statistically significant associations between antibiotic drop exposure and grommet blockage (p > 0.05). There was a significant association between developing postoperative otorrhoea and patients receiving surgery during the colder months of Winter/Autumn (OR = 3.17, 95%CI 1.14 to 8.84, p = 0.028), as well as patients aged less than 3 years (OR = 2.66, 95%CI 1.01 to 7.03, p = 0.049). There was a statistically significant association between serous effusions and grommet blockage compared to no effusion (OR = 4.03, 95%CI 1.03 to 15.7, p = 0.045). There were no statistically significant associations identified between otorrhoea and gender, weight/BMI percentile, intraoperative middle ear status, number of previous grommets, type of surgery, diagnosis and time to first medical review. There were no statistically significant associations between grommet blockage and age, gender, indication for surgery, concurrent surgery, season or number of previous grommets., Conclusions: 8.7% of patients developed otorrhoea within 6 weeks post-operatively. Undergoing the procedure during winter/autumn, age <3 years were associated with developing otorrhoea. Topical antibiotic exposure was inversely associated with developing postoperative otorrhoea. 6.4% of patients had grommet blockage. Presence of serous middle ear effusion intraoperatively was a statistically significant indicator for developing grommet blockage., (Crown Copyright © 2020. Published by Elsevier B.V.

Objective: Recent studies have investigated the mechanism by which refluxed gastric materials reach the middle ear, to establish otitis media with effusion (OME) causal relation between them in both children and adults. Therefore, the relationship between OME and gastro-esophageal reflux disease (GERD) should be further studied extensively., Methods: To identify eligible original articles, we searched a range of computerized databases, including Medline via PubMed, EMBASE, CNKI, and Web of Science with a systematic searching strategy. Subgroup analysis was performed to analyze heterogeneity and Egger and Begg funnel plot to assess the publication bias of the included articles., Results: The meta-analysis had an overall sample size of 1961. We identified a significant relationship between OME and GERD, with a pooled odds ratio (OR) of 4.52 (95% confidence interval [CI]: 2.42-8.44; p < 0.001). The pooled data were calculated with the random-effects model as a high significant heterogeneity was found among the studies and there was no significant publication bias observed., Conclusions: The meta-analysis suggested that there was a significant association between otitis media with effusion and gastroesophageal reflux disease., Competing Interests: The authors disclose no conflicts of interest., (Copyright © 2020, Otology & Neurotology, Inc.)

Objective: To evaluate the factors contributing to middle ear pathology, hearing and speech development among cleft palate children treated for middle ear effusion., Method: A prospective cross-sectional otoscopic and audiological analysis was conducted on 102 cleft palate children (204 ears) aged 1-18 years old who were treated for middle ear effusion at our centre. Retrospective chart review was done to determine patient characteristics and prior patient management. The aim was to assess the effect of ventilation tube insertion (VTI) on hearing, speech and chronic otitis media; comparing the timing and number of ventilation tubes per ear and determining other factors affecting the short-term and long-term outcome., Results: 68 children or 130 ears (63% of all cases) were selectively treated with ventilation tube insertion. Repeat procedures (more than 2) were performed in 41 ears. Among children with VTI performed, the incidence of chronic otitis media in children after the age of 4 was 17%. Overall, abnormal tympanic membrane findings and hearing loss were detected in nearly half the cases who were previously treated with VTI. Early ventilation tube insertion at less than 1 year of age, resulted in a better middle ear and hearing outcome in children less than 4 years old (p < 0.05), however there was no significant difference in children more than 4 years old. Early surgical repair of cleft palate prior to the age of one year resulted in favourable results in both age groups (p < 0.05). There was a higher prevalence of chronic otitis media with repeated grommet insertion (3 or more) (p < 0.05). Speech and language milestones were achieved in 94% of all children above the age of four., Conclusion: Treatment with early ventilation tube insertion prior to the age of one year provides a hearing benefit in children less than 4 years of age, but no significant difference after 4 years of age. Factors significantly affecting the outcome after 4 years of age was the timing of palatal closure and total number of tube insertions. We recommend a conservative approach especially when considering repeated tube insertions. A long-term follow-up paired with interval hearing assessment is advocated until early adulthood., (Copyright © 2020 Elsevier B.V. All rights reserved.)

Aim: To evaluate the feasibility of a two-stage screening strategy for otitis media with effusion (OME) in pre-school and school children. The risk factors of OME were also studied., Methods: One hundred and eighty-nine children aged 4-8 years were recruited. The two-stage screening consisted of an on-site screening with a portable otoscopy along with a questionnaire to both diagnose children with OME and identify children at risk, and a standard screening performed at a regional hospital for final diagnosis. The prevalence detected from the two-stage screening approach was compared to the actual prevalence., Results: The detection rate of OME through the two-stage screening approach was not significantly different from the actual prevalence rate (12.7% vs. 13.4%, P = 0.847). Children from the urban area had a lower risk for OME than that from the rural area (P = 0.007, odds ratio (OR) = 0.28, 95% confidence interval (CI): 0.11-0.74). Compared to childcare dining, family dining helped to reduce the chance of OME (P < 0.001, OR = 0.15, 95% CI: 0.06-0.38)., Conclusions: The two-stage screening strategy was effective for screening for OME among pre-school and school children. It can be used in rural areas that have a high prevalence of OME and limited medical resources., (© 2020 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).)

Background: Studies have shown that Helicobacter pylori (H. pylori) infection may be associated with the occurrence of otitis media with effusion (OME) in children., Objective: This is a systematic review of the relevant published literature to explore the relationship between H. pylori infection and OME in children., Method: Articles published before October 30, 2019 in the PubMed, Web of Science, Ovid, the China National Knowledge Infrastructure (CNKI) database, and Wanfang databases were retrieved. Articles were screened based on prespecified inclusion and exclusion criteria. Quality assessment was applied to the included studies. Data in the included studies were extracted and classified for qualitative analysis., Results: Ten studies, which enrolled a total of 397 cases and 334 controls, were included; all were case-control studies of varying quality. We summarized and compared H. pylori infections in different specimens from pediatric patients with OME. Due to the apparent heterogeneity between the included studies, meta-analysis was not appropriate, hence we carried out only a qualitative analysis., Conclusion: The detection rate of H. pylori in the middle ear, tonsil and gastric juice in children with OME was higher than that in children without OME. There is no clear and reliable conclusion as to whether there is a difference in the detection rate of H. pylori in adenoid specimens of children with or without OME. Eradication of H. pylori may improve symptoms of drug-resistant OME. Nevertheless, more studies of higher quality are needed to improve the conclusions., Competing Interests: Declaration of competing interest None., (Copyright © 2020 Elsevier B.V. All rights reserved.)
