Congenital aural atresia (CAA) is characterized by hypoplasia or aplasia of external auditory canal associated with auricular deformity. It also embodies a spectrum of temporal bone abnormalities including anomalies of middle ear, ossicles, facial nerve, oval window, round window, mastoid pneumatization, temporomandibular joint and occasionally inner ear and vascular anomalies. The management in such patients is variable and consists of rehabilitative hearing aids or surgical correction depending on various patient factors like associated temporal bone abnormalities, degree of hearing impairment and laterality. Surgical management if planned, depends on the extent of associated temporal bone anomalies and hence necessitates comprehensive knowledge about the normal and abnormal anatomy of these structures. High resolution computed tomography (HRCT) is the optimal investigation which provides required anatomical information and plays a pivotal role in deciding the management strategy. This pictorial review aims to review the spectrum of anomalies involving critical structures in CAA on HRCT along with their clinical significance.

Dyskeratosis congenita is a rare disease caused by telomerase dysfunction classically characterised by the triad: skin pigmentation, nail dystrophy and mucosal leukoplakia. Few cases are described in literature regarding patients with head and neck squamous cell carcinoma affected by dyskeratosis congenita, and the therapeutic decisions are not yet well defined. A review of the literature of the last 20 years (2001–2021) was performed, and it was analysed the case of a 38-year-old male patient affected by dyskeratosis congenita diagnosed with a squamous cell carcinoma of the inferior alveolar ridge, treated with surgery. The absence of complications and the good postoperative recovery of the patient comfort in saying that resection and reconstructive surgery can be safely performed. The occurrence of disseminated disease 6 months after the treatment warns about the extreme aggressiveness of the pathology, its often systemic nature and the necessity of a multidisciplinary approach as well as further studies.

Introduction: Squamous cell carcinoma of the external auditory canal is a rare entity. Previous studies have suggested predictors for tumor recurrence. However, most of the prognostic factors were from the clinicopathological aspect. Objective: This study aims to analyze the correlation between pre-operative peripheral inflammation markers and survival outcomes, in order to identify prognostic biomarkers for patients with squamous cell carcinoma of the external auditory canal. Methods: We retrospectively analyzed patients diagnosed with squamous cell carcinoma of the external auditory canal who underwent surgery at our institute. The pre-operative circulating inflammatory markers, such as the neutrophil, lymphocyte, platelet, and monocyte counts were measured and their ratios including neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio and lymphocyte-to-monocyte ratio were calculated. The prognostic value of the measured hematologic parameters in relation to the survival outcomes was also evaluated. Results: A total of 83 patients were included, of which 26 patients showed tumor recurrence and 57 without recurrence. Neutrophil counts and neutrophil-to-lymphocyte ratio were closely connected with tumor stage. In the patients with recurrence, neutrophil counts, neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio were elevated (p< 0.0001, p< 0.0001 and p = 0.001), while lymphocyte counts and lymphocyte-to-monocyte ratio were decreased (p = 0.013 and p = 0.016, respectively). The receiver operating curve analysis indicated that pre-operative neutrophil-to-lymphocyte ratio is a potential prognostic marker for recurrence of squamous cell carcinoma of the external auditory canal (area under curve = 0.816), and the cut-off points was 2.325. Conclusions: Pre-operative neutrophil and lymphocyte counts, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, lymphocyte-to-monocyte are significantly correlated with tumor recurrence in patients with external auditory canal squamous cell carcinoma. Furthermore, neutrophil-to-lymphocyte ratio may be unfavorable prognostic factors of this disease. Resumo Introdução: O carcinoma espinocelular do meato acústico externo é uma doença rara. Estudos anteriores sugeriram preditores de recorrência do tumor. Entretanto, a maioria dos fatores prognósticos se originou do aspecto clínico-patológico. Objetivo: Analisar a correlação entre marcadores inflamatórios periféricos pré-operatórios e os desfechos de sobrevida e identificar biomarcadores prognósticos para pacientes com carcinoma espinocelular do meato acústico externo. Método: Analisamos retrospectivamente pacientes com diagnóstico de carcinoma espinocelular do meato acústico externo submetidos à cirurgia em nosso instituto. Os marcadores inflamatórios circulantes pré-operatórios, como as contagens de neutrófilos, linfócitos, plaquetas e monócitos, foram medidos e as suas relações calculadas, inclusive as relações neutrófilos/linfócitos, plaquetas/linfócitos e linfócitos/monócitos. O valor prognóstico dos parâmetros hematológicos medidos em relação aos desfechos de sobrevida também foi avaliado. Resultados: Foram incluídos 83 pacientes, entre os quais 26 apresentaram recorrência tumoral e 57 não apresentaram. A contagem de neutrófilos e a relação neutrófilo/linfócito estavam intimamente associadas ao estágio do tumor. Nos pacientes com recorrência, a contagem de neutrófilos, a relação neutrófilos/linfócitos e a relação plaquetas/linfócitos eram elevadas (p < 0,0001, p > 0,0001 e p = 0,001), enquanto a contagem de linfócitos e a relação linfócitos/monócitos estavam diminuídas (p = 0,012 ep = 0,016, respectivamente). A análise da curva, Receiver Operating Characteristic, indicou que a relação neutrófilos/linfócitos pré-operatória era um potencial marcador prognóstico para a recorrência de carcinoma espinocelular do meato acústico externo (Área sob a curva = 0,816) e o ponto de corte foi de 2,325. Conclusão: A contagem pré-operatória de neutrófilos e linfócitos, as relações neutrófilos/linfócitos, plaquetas/linfócitos e linfócitos/monócitos estão significativamente correlacionadas com a recorrência do tumor em pacientes com carcinoma espinocelular do meato acústico externo. Além disso, a relação neutrófilos/linfócitos pode ser um fator prognóstico desfavorável dessa doença.

BACKGROUND: Sinus barotraumas are a common condition in aviation medicine, sometimes compromising flight safety and even permanently grounding aircrew. Considering this and the ever-increasing amount of commercial aviation, a thorough examination is required.METHODS: In this survey study, an anonymous, electronic questionnaire was distributed to commercial aircrew of the three major commercial airlines operating in Finland (N = 3799), covering 93% of the target population (i.e., all commercial aircrew operating in Finland, N = 4083). Primary outcomes were self-reported prevalence, clinical characteristics, and health and occupational effects of sinus barotraumas in flight. Secondary outcomes were adjusted odds ratios (OR) for frequency of sinus barotraumas with respect to possible risk factors.RESULTS: Response rate was 47% (N = 1789/3799), with 61% (N = 1088) of the respondents having experienced sinus barotraumas in flight. Of those affected, 59% had used medications, 18% had undergone surgical procedures, and 53% had been on sick leave due to sinus barotraumas (38% during the last year) in flight. Factors associated with sinus barotraumas were female sex [OR, 2.47; 95% confidence interval (CI) 1.35–4.50] and a high number of upper respiratory tract infections (≥3 vs. CONCLUSION: Sinus barotraumas were reported by 61% of commercial aircrew. They caused an increased need for medications, otorhinolaryngology-related surgical procedures, and sickness absence from flight duty. The possible risk factors were female sex and a high number of URTIs/yr.Lindfors OH, Ketola KS, Klockars TK, Leino TK, Sinkkonen ST. Sinus barotraumas in commercial aircrew.

OBJECTIVE To describe the audiological results and complications following active middle ear implant (AMEI) surgery in users with bilateral ear atresia. STUDY DESIGN Observational and retrospective longitudinal follow-up. SETTING A tertiary referral hospital for hearing rehabilitation and craniofacial malformations. PATIENTS Medical records of 27 patients with bilateral congenital aural atresia (34 ears) who underwent surgery for AMEI were reviewed. Data were analyzed using descriptive and inferential statistics. The alpha error was assumed to be 5%. OUTCOME MEASURES Medical and technical complications and audiological results were observed during follow-up. RESULTS The median postoperative follow-up was 37.5 months (27.7-75.5 mo). Medical or technical complications occurred in 35.3% (n = 12) of patients during follow-up, 14.7% (n = 5) required surgical revision. The auditory thresholds in the free field improved from 53.75 dB (46.87-56.25) to 25 dB (21.25-32.5) after 6 months using the AMEI (p

Background: European health-care systems are faced with a backlog of surgical procedures following the suspension of routine surgery during the COVID-19 crisis. Routine rhinology surgery under general anaesthetic (GA) is now faced with significant challenges which include limited theatre capacity, the negative ramifications of surgical prioritization, reduced patient throughput in secondary care, and additional personal protective equipment requirements. Delayed surgery in rhinology, particularly with regards to chronic rhinosinusitis, has previously been shown to have poorer surgical outcomes, a detrimental effect on quality of life and long-term negative health socio-economic effects. Awake rhinology surgery under local anaesthetic (LA) provides an ideal alternative to GA. It provides a means of operating on patients in a setting alternative to currently oversubscribed main theatres, by utilizing satellite facilities, while ensuring identical surgical outcomes for patients who may otherwise have been forced to wait a long time for their procedure. It also confers additional benefits in terms of shorter recovery time and hospital stay for patients. Objectives: We have developed a set of recommendations that are intended to help support clinicians and managers to better adopt LA rhinology protocols and minimize the risk to the patient and health-care professionals involved. Methodology: International roundtable forums were conducted and supplemented by individual interviews. The international board consisted of 12 rhinologists experienced in awake rhinology surgery. Feedback was analysed and shared to develop a consensus of best practice. Recommendations: Local and national guidelines need to be adhered to with specific focus on patient and clinician safety. When performing awake rhinology procedures in the COVID-19 recovery process, consider implementing specific safety measures and workflow practices to safeguard patients and staff and minimize the risk of infection. Conclusion: Awake surgery potentially provides quicker access to routine rhinology surgery in the post-COVID-19 recovery phase, ensuring patients are treated in a timely matter, thereby avoiding higher downstream costs, and improving outcomes.

Background The aim of the study was to identify the value of extensive resection and reconstruction with flaps in the treatment of locoregionally advanced lateral skull-base cancer. Patients and methods The retrospective case review of patients with lateral skull-base cancer treated surgically with curative intent between 2011 and 2019 at a tertiary otorhinolaryngology referral centre was made. Results Twelve patients with locoregionally advanced cancer were analysed. Lateral temporal bone resection was performed in nine (75.0%), partial parotidectomy in six (50.0%), total parotidectomy in one (8.3%), ipsilateral selective neck dissection in eight (66.7%) and ipsilateral modified radical neck dissection in one patient (8.3%). The defect was reconstructed with anterolateral thigh free flap, radial forearm free flap or pectoralis major myocutaneous flap in two patients (17.0%) each. Mean overall survival was 3.1 years (SD = 2.5) and cancer-free survival rate 100%. At the data collection cut-off, 83% of analysed patients and 100% of patients with flap reconstruction were alive. Conclusions Favourable local control in lateral skull-base cancer, which mainly involves temporal bone is achieved with an extensive locoregional resection followed by free or regional flap reconstruction. Universal cancer registry should be considered in centres treating this rare disease to alleviate analysis and multicentric research.

OBJECTIVE Congenital aural atresia causes severe conductive hearing loss disturbing auditory development. The differences in speech recognition were investigated between bilateral and unilateral aural atresia. DESIGN The maximum speech recognition scores (SRSs) were compared between patients with bilateral and unilateral aural atresia. In patients with unilateral aural atresia, the maximum SRSs were compared between the atretic and unaffected ears. Furthermore, the correct response rates for test material monosyllables were compared with those of patients with sensorineural hearing loss (SNHL), which had been previously obtained. STUDY SAMPLE Twenty-four patients with aural atresia (8 bilateral, and 16 unilateral) participated. RESULTS The maximum SRS in unilateral atretic ears (median: 72%) was significantly lower than that in unaffected ears (median: 89%) (p

ObjectiveThis case series, conducted during the coronavirus disease 2019 pandemic, investigates the impact of leaving aural foreign bodies in situ for a prolonged period of time, including the risk of complications and success rates of subsequent removal attempts.MethodA retrospective study of aural foreign body referrals over a six-month period was carried out.ResultsThirty-four patients with 35 foreign bodies were identified (6 organic and 29 inorganic). The duration of foreign bodies left in situ ranged from 1 to 78 days. Four patients suffered from traumatic removal upon initial attempts. First attempts made by non-ENT specialists (68.8 per cent) all failed and were associated with a high risk of trauma (36.4 per cent).ConclusionBecause of the coronavirus disease 2019 pandemic, this is the first case series to specifically investigate the relationship between the duration of aural foreign bodies left in situ and the risk of complications. Our data suggest that prolonged duration does not increase the incidence of complications.

ObjectiveThis study investigated how the coronavirus disease 2019 pandemic has impacted on presentations to ENT first-on-call services.MethodsAll appointments to a rapid access triage clinic from 1 June to 31 August in 2019 and 2020 were reviewed retrospectively and their reasons for consultation classified. A binomial proportion test was used to determine whether the proportions of consultations per presentation differed significantly between years. This analysis was repeated with the number of unique patients per presenting complaint.ResultsThe proportions of nine reasons for consultation differed significantly between 2019 and 2020, including an increase in otitis media and nasal trauma presentations, and a decrease in otitis externa and tonsillitis presentations. Reattendances caused some variation in the frequency of certain diagnoses.ConclusionOur data suggest a shift in the presentations to first-on-call services, which may be a result of changes in patient behaviour and access to healthcare services.

Spitz nevi of special sites, such as the ear, appear rarely and pose a challenge with worrisome clinical, dermoscopic, or histopathological features. Our aim was to evaluate the morphological findings of a series of Spitz nevi of the ear in order to obtain more knowledge about their clinical-dermoscopic patterns. Of a total of six cases, three main dermoscopic structures were found: pseudonetwork, structureless areas, and cobblestone pattern. Our preliminary findings suggest that dermoscopy may be helpful in improving the diagnostic accuracy of Spitz nevus of the ear and minimize surgery in a sensitive location.

The auditory biology of Monachinae seals is poorly understood. Limited audiometric data and certain anatomical features suggest that these seals may have reduced sensitivity to airborne sounds compared to related species. Here, we describe the in-air hearing abilities of a Hawaiian monk seal (Neomonachus schauinslandi) trained to participate in a psychophysical paradigm. We report absolute (unmasked) thresholds for narrowband signals measured in quiet conditions across the range of hearing and masked thresholds measured in the presence of octave-band noise at two frequencies. The behavioral audiogram indicates a functional hearing range from 0.1 to 33 kHz and poor sensitivity, with detection thresholds above 40 dB re 20 µPa. Critical ratio measurements are elevated compared to those of other seals. The apparently reduced terrestrial hearing ability of this individual—considered with available auditory data for a northern elephant seal (Mirounga angustirostris)—suggests that hearing in Monachinae seals differs from that of the highly sensitive Phocinae seals. Exploration of phylogenetic relationships and anatomical traits support this claim. This work advances understanding of the evolution of hearing in amphibious marine mammals and provides updated information that can be used for management and conservation of endangered Hawaiian monk seals.

Objective: To evaluate early results on hygiene, safety and functional outcome in a population undergoing a canal wall up technique with bony obliteration of the mastoid and epitympanic space (CWU-BOT) for extensive cholesteatoma, performed by a single surgeon. This study compares different techniques of tympanic membrane reconstruction, viz. allografts and autografts. Patients: A consecutive series of 61 ears with acquired cholesteatoma treated with primary or revision CWU-BOT surgery from 2009 to 2014. Intervention: Obliteration was performed by the use of cortical bone-chips and bone pâté. Patients were followed up with micro-otoscopy and MRI with diffusion-weighted imaging. Ossicular reconstruction was performed using a remodelled autologous or allogenic incus or malleus. Main outcome measures: Residual and recurrence rate and short- and mid-term hearing outcome prior to any revision tympanoplasty were analysed, the effect of type of tympanic membrane reconstruction was considered. Results: 44 Ears were primary cholesteatoma cases, 17 cases were referred for revision surgery. Mean postoperative follow up was 45 months (SD 18.08) and mean follow-up until the last non-EP DW MRI 42 months (SD 17.72). Recurrent disease was present in 3%, no residual disease was present. An AC gain was seen in 75% of all ears undergoing ossicular reconstruction. Conclusion: Reproducible safety, hygiene and hearing results with limited recurrence and residual disease can be obtained by younger otologic surgeons performing the BOT-CWU for extensive cholesteatoma while using a variety of grafts for tympano-ossicular reconstruction. The tympano-ossicular allograft nevertheless shows superior hearing results when a mobile intact stapes is present. Level of evidence: Level 4

BackgroundEar disease is a major cause of preventable hearing loss and is very common in rural communities, estimated to affect 1.3 million Australians. Rural community pharmacists are well placed to provide improved ear health care to people who are unable to easily access a general practitioner (GP). The purpose of this study is to apply an ear health intervention to the rural community-pharmacy setting in Queensland, Australia, to improve the management of ear disease. The aims are the following: (1) to evaluate the feasibility, potential effectiveness and acceptability of a community pharmacy-based intervention for ear health, (2) to evaluate the use of otoscopy and tympanometry by pharmacists in managing ear complaints in community pharmacy and (3) to evaluate the extended role of rural pharmacists in managing ear complaints, with the potential to expand nationally to improve minor ailment management in rural communities.Methods/designThis is a longitudinal pre- and post-test study of a community-pharmacy-based intervention with a single cohort of up to 200 patients from two rural community pharmacies. Usual care practices pertaining to the management of ear complaints will be recorded prior to the intervention for 8 weeks. The intervention will then be piloted for 6 weeks, followed by a 12 month impact study. Patients aged > 13 years presenting to the pharmacies with an ear complaint will be invited to participate. Trained pharmacists will conduct an examination including a brief history, hearing screening, otoscopy and tympanometry assessments. Patients will be referred to a general practitioner (GP) if required, according to the study protocol. Patients will complete a satisfaction survey and receive a follow-up phone call at 7 days to explore outcomes including prescribed medications and referrals. Pharmacists and GPs will complete pre- and post- intervention interviews. Patient, pharmacist and GP data will be analysed using descriptive statistics and thematic analysis for the qualitative data.DiscussionThis study will demonstrate the implementation of a screening and referring ear health intervention in rural community pharmacy. Feasibility, potential effectiveness and acceptability of the intervention will be assessed.Trial registrationAustralian and New Zealand Clinical Trial Registry Number:ACTRN12620001297910.

American Cocker Spaniels (ACSs) develop aural ceruminous gland hyperplasia and ectasia more often than dogs of other breeds. Data on the cause and development of these breed characteristic histopathological changes are lacking. We performed video-otoscopic examinations and dermatological work-up on 28 ACSs, obtained aural biopsies from each dog and assessed the statistical associations between the presence of ceruminous gland hyperplasia and ectasia and disease history, clinical or microbiological findings and underlying cause of otitis externa (OE). Histological lesions of ceruminous gland hyperplasia and ectasia were observed in aural biopsies from 6/13 clinically healthy ears and 13/15 ears with OE from 19/28 examined dogs. Nine of 28 dogs had histologically normal ceruminous glands (odds ratio [OR] 6.2, 95% confidence interval [CI] 1.1-36.6). Bacterial growth in microbiological culture of aural exudate (OR 14.1, 95% CI 2.1-95.3) was associated with ceruminous glandular changes, whereas previous history of OE, cutaneous findings or underlying allergies were not. Pedigree analysis and a genome-wide association study (GWAS) were performed on 18 affected and eight unaffected dogs based on histopathological diagnosis. While the GWAS indicated a tentative, but not statistically significant, association of ceruminous gland hyperplasia and ectasia with chromosome 31, a larger cohort is needed to confirm this preliminary result. Based on our results, ceruminous gland hyperplasia and ectasia may also precede clinical signs of OE in ACSs and a genetic aetiological component is likely Further studies with larger cohorts are warranted to verify our preliminary results.

Introduction:To investigate the relationship between morphometric variants of the cochlear nerve (CN) and the hearing level. To investigate the confounding effects of age, sex, and audiometric variables on the relationship between CN morphometrics and hearing loss, if present.Methods:Audiological data and magnetic resonance imaging findings of 127 patients with asymmetrical sensorineural hearing loss (ASNHL) were reviewed retrospectively. According to pure tone average (PTA) frequencies of each ear, difference above 25 dB were accepted as ASNHL. The vertical (Vd) and horizontal diameters (Hd) and the cross-sectional area (CSA) of the CN were measured.Results:The difference in CSA and Vd between ears showed a negative correlation with age. The mean CSA was 1.57 in AE and 1.60 in NE. Mean Hd was 1.00 in AE and 1.00 NE. Mean Vd was 1.40 in AE and 1.50 in NE. There was no correlation between the difference ratios of thresholds and CN diameter parameters. There was no significant correlation of CSA, Vd, and Hd with PTA thresholds at each frequency.Conclusion:Aging is associated with losses in Vd diameter and CSA. The degree of hearing loss was not correlated with the morphometric features of the CN. The morphometry of the CN should be interpreted together with the etiology of hearing loss.

Background: Fetal ear length measurement has been associated with some clinical values: sonographic marker for chromo- somal aneuploidy and for biometric estimation of fetal gestational age. Objectives: To establish a baseline reference value for fetal ear length and to assess relationship between fetal ear length and gestational age. Methods: Ear length measurements were obtained prospectively from fetuses in 551 normal singleton pregnancies of 15 to 41 weeks gestation. Normal cases were defined as normal sonographic findings during examination plus normal infant post-delivery. The relationship between gestational age (GA) in weeks and fetal ear length (FEL) in millimeters were analyzed by simple linear regression. Correlation of FEL measurements with GA, biparietal diameter (BPD), Head circumference (HC), Abdominal Circumference (AC), Femur Length (FL) and maternal age (MA) were also obtained. Results: Linear relationships were found between FEL and GA (FEL=0.872GA-2.972). There was a high correlation between FEL and GA (r = 0.837; P = .001). Good linear relationship and strong positive correlation were demonstrated between FEL and BPD, AC, HC, and FL (p

Recalcitrant auricular keloids are keloids that have recurred after any previous treatment. They have been shown to have an increased likelihood of recurrence. There is no consensus on how best to treat recalcitrant auricular keloids. Here, we perform the first systematic review and meta-analysis investigating the evidence for treating recalcitrant auricular keloids.We searched MEDLINE, EMBASE, CINAHL, and EBM Reviews using specific keywords. Prespecified inclusion and exclusion criteria were used to assess article eligibility. Data were extracted for number of recalcitrant keloids, treatment modality, recurrence, and minimum follow-up time. Included articles were stratified by treatment and assigned a level of evidence (LOE) based on the Oxford Centre for Evidence-Based Medicine guidelines. A meta-analysis was performed to estimate recurrence rates with 95% confidence intervals for each treatment modality.A total of 887 unique articles were identified and 13 included. Eleven were LOE III and 2 were LOE IV. Recurrence rates were found to be 9% (95% CI: 3%-25%) for excision with adjuvant brachytherapy, 14% (95% CI: 12%-17%) for excision with adjuvant compression therapy, 17% (95% CI: 3%-56%) for excision with adjuvant external beam radiation, and 18% (95% CI: 4%-53%) for excision with adjuvant steroid injections. No statistical significant difference was found.Data for treatment of auricular keloids are heterogeneous with few high-quality studies. Excision with adjuvant brachytherapy has the lowest recurrence rate in our analysis. Narrow confidence intervals reported here for brachytherapy and compression therapy may help surgeons more confidently recommend either of these treatment modalities to patients.Les chéloïdes auriculaires récalcitrantes sont celles qui se manifestent de nouveau après un traitement. Il est démontré que leur risque de récurrence est plus élevé. Il n’y a pas de consensus au sujet de leur traitement. Les chercheurs procèdent à la première analyse systématique et méta-analyse sur les données probantes relatives au traitement des chéloïdes auriculaires récalcitrantes.Les chercheurs ont fouillé les bases de données MEDLINE, EMBASE, CINAHL et EBM Reviews au moyen de mots-clés précis. Ils ont utilisé des critères d’inclusion et d’exclusion préétablis pour évaluer l’admissibilité des articles. Ils ont extrait les données relatives au nombre de chéloïdes récalcitrantes, à la modalité thérapeutique, à la récurrence et à la durée minimale du suivi. Ils ont stratifié les articles retenus d’après le traitement utilisé et leur ont attribué une qualité de preuve (QdP) en fonction des directives de l’Les chercheurs ont relevé 887 articles uniques et en ont retenu 13. De ce nombre, 11 avaient une QdP III et deux, une QdP IV. Ils ont constaté un taux de récurrence de 9 % (IC à 95 %, 3 % à 25 %) après une excision et une curiethérapie adjuvante, de 14 % (IC à 95 %, 12 % à 17 %) après une excision et une thérapie de compression adjuvante, de 17% (IC à 95 %, 3 % à 56 %) après une excision et une radiothérapie externe adjuvante, et de 18 % (IC à 95 %, 4 % à 53 %) après une excision et des injections adjuvantes de stéroïdes. Ils n’ont constaté aucune différence statistiquement significative.Les données relatives au traitement des chéloïdes auriculaires sont hétérogènes, et peu d’études sont de qualité. À l’analyse, l’excision avec curiethérapie adjuvante présente le taux de récurrence le plus faible. Les faibles intervalles de confiance liés à la curiethérapie et à la thérapie de compression pourraient inciter les chirurgiens à recommander avec conviction l’une de ces deux modalités thérapeutiques aux patients.

To present a large series ears with tympanic membrane perforations (TMP), to describe their characteristics, and to propose a new classification system based on the pathogenesis of TMP. This cross-sectional study was conducted at a tertiary university hospital with 1003 ears (792 consecutive patients with TMP in at least 1 ear). Otoendoscopy and audiometry were performed. Perforation measurements and their locations were digitally assessed. TMP with no suggestive signs of previous retraction were classified as Group 1, and those with possible previous retraction were classified as Group 2. Signs of retraction previous to the TMP, symptom length, perforation size and location, status of the contralateral ear, and hearing status were compared. Group 1 comprised 63.5% of the included ears. Compared to Group 2, Group 1 presented a higher rate of central perforations (99% vs. 53%), a shorter duration of symptoms, smaller perforations (mean area: 18.5% vs. 41.4%), a higher rate of perforations in the anterior quadrants, better hearing levels (mean tritonal gap: 23.9 dB vs. 29.2 dB), and a lower rate of abnormal contralateral ears (28% vs. 66%). The classification of TMP into two groups based on signs of previous retractions is feasible and indicates two different levels of disease severity. While the group without previous signs of retraction comprises ears with more limited disease, membranes with previous retraction seem to show more severe disease and, consequently, a less functional middle ear.

Objective To explore the behavioural and functional performance of a group of children with conductive unilateral hearing loss (UHL) due to congenital aural atresia. Method Twelve children aged 7 to 16 years (Mage 10.0, SD 3.1 years) formed the UHL group and 15 age-matched children (Mage 9.5, SD 3.6 years) with normal hearing formed the control group. Auditory skills were assessed using tests of sound localisation, spatial speech perception in noise, and self-ratings of auditory abilities (Listening Inventory for Education; LIFE and Speech, Spatial and Qualities of Hearing scale; SSQ). Results When speech was directed to the good ear, performance was poorer than for normal hearing controls. Sound localisation abilities were impaired in children with UHL. Children with UHL reported higher levels of difficulties in classroom settings compared to children with normal hearing, particularly for activities involving listening in noise and focused listening activities. Older children self-report and parents report difficulties for their children across all SSQ scales. Conclusions Children with UHL showed a wide range of auditory difficulties. As expected, speech recognition in noise differed from controls. Sound localisation abilities were variable; greater variability was seen for right ear hearing losses suggesting that some of these children may have developed compensatory mechanisms. Younger children identified listening difficulties for school situations where focussed auditory attention was needed. Older children and parents reported greatest difficulty for activities requiring perception of the direction, distance, and movement of sound. Higher levels of effort and inability to ignore sounds were reported as major difficulties.

In patients who require a gastric pull‐up, despite bilateral injury to the vocal cords and regurgitation, preservation of the larynx can improve their quality of life.

BackgroundCoronavirus disease 2019 imposed dramatic changes on ENT service delivery. Pre-pandemic, such changes would have been considered potentially unsafe. This study outlines the impact of lockdown on the incidence and management of ENT emergencies at a large UK centre.MethodsAfter modification of pre-pandemic guidelines, ENT emergency referrals data during the UK lockdown were prospectively captured. A comparative analysis was performed with retrospective data from a corresponding period in 2019.ResultsAn overall reduction (p< 0.001) in emergency referrals (n= 119) and admissions (n= 18) occurred during the lockdown period compared to the 2019 period (432 referrals and 290 admissions). Specifically, there were reduced admission rates for epistaxis (p< 0.0001) and tonsillar infection (p< 0.005) in the lockdown period. During lockdown, 90 per cent of patients requiring non-dissolvable nasal packing were managed as out-patients.ConclusionsCoronavirus disease 2019 compelled modifications to pre-pandemic ENT guidelines. The enforced changes to emergency care appear to be safe and successfully adopted. Arguably, the measures have both economic and patient-related implications post-coronavirus disease 2019 and during future similar pandemics and lockdowns.

Implantable bone-conduction hearing aids (BCHA) are effective in patients with congenital ear malformations.However, there is no large sample study to verify the efficacy of Bonebridge in patients with congenital oval window atresia.To investigate efficiency of implantable bone-conduction hearing aids in Mandarin-speaking patients with congenital oval window atresia.We retrospectively analyzed 15 patients, who were confirmed with either unilateral or bilateral congenital oval window atresia by temporal bone CT. All patients were implanted with a bone-conduction hearing device between July 2016 and July 2019 at Beijing Tongren Hospital, Capital Medical University. Pure tone audiometry (PTA), air-bone gap (ABG), speech discrimination scores (SDSs), and hearing thresholds were performed.Postoperative complications including facial paralysis were particularly rare. Unaided mean sound field threshold was 62.2 ± 10.5 dBHL and that with implantable bone-conduction hearing aids was 39.1 ± 13.2 dBHL (Patients with congenital oval window atresia often show moderate to severe conductive hearing loss. Implantable bone-conduction hearing aids are considerably safe and stable for hearing rehabilitation. It is a novel treatment modality for Mandarin-speaking patients with congenital oval window atresia.

Patients affected by severe atresia auris (AA) can be a challenge during hearing restoration surgery due to the abnormal position of vascular and nervous structures in the bone. A 3D reconstruction model of malformed temporal bones can be helpful for planning surgery and optimizing intra-, peri-, and post-operative results. A 5-year-old girl with severe AA on the right side was implanted with a Bonebridge transcutaneous bone conduction implant (tBCI). 3D printing was used to reproduce the malformed temporal bone, find a good position for the tBCI and plan out the surgical details in advance. Hearing tests were performed before and after surgery and information about intra-, peri-, and post-operative outcomes were collected. The patient did not show any negative outcomes and, thanks to the Bonebridge, completely recovered hearing on the right side. 3D printing is a useful tool for planning surgery in AA patients and for preventing possible risks related to the unknown malformed anatomy.

Cochlear implants are very well established in the rehabilitation of hearing loss and are regarded as the most successful neuroprostheses to date. While a lot of progress has also been made in the neighboring field of specific vestibular implants, some diseases affect the entire inner ear, leading to both hearing and vestibular hypo- or dysfunction. The proximity of the cochlear and vestibular organs suggests a single combined implant as a means to alleviate the associated impairments. While both organs can be stimulated in a similar way with electric pulses applied through implanted electrodes, the typical phase durations needed in the vestibular system seem to be substantially larger than those typically needed in the cochlear system. Therefore, when using sequential stimulation in a combined implant, the pulse stream to the cochlea is interrupted by comparatively large gaps in which vestibular stimulation can occur. We investigate the impact of these gaps in the auditory stream on speech perception. Specifically, we compare a number of stimulation strategies with different gap lengths and distributions and evaluate whether it is feasible to use them without having a noticeable decline in perception and quality of speech. This is a prerequisite for any practicable stimulation strategy of a combined system and can be investigated even in recipients of a normal cochlear implant. Our results show that there is no significant deterioration in speech perception for the different strategies examined in this paper, leaving the strategies as viable candidates for prospective combined cochleo-vestibular implants.

OBJECTIVE To determine reasons for premature termination in surgery for congenital aural atresia (CAA). STUDY DESIGN Retrospective chart review. SETTING High-volume tertiary care center. PATIENTS Patients undergoing primary surgical repair of CAA whose surgeries were aborted for various indications. INTERVENTION Patients with CAA who underwent elective aural atresia surgery at the University of Virginia from July 2004 to January 2020 were identified from the medical record and an institutional database of patients with CAA. Patients undergoing revision surgery or surgery not for hearing correction were excluded. All included candidates were noted to be good surgical candidates for atresia repair based on preoperative Jahrsdoerfer score of 6 or greater. Reasons for terminating surgery prematurely were categorized by anatomical constraints (inability to identify middle ear space, position of the facial nerve, or other anatomic abnormality), stapes fixation, and middle ear and/or mastoid inflammatory disease. MAIN OUTCOME MEASURES Reasons for premature termination in CAA surgery. RESULTS Over the interval, 319 patients underwent primary surgery for CAA. Surgery was terminated prematurely without completing the primary objective in 14 patients (4.4%); surgery was terminated in 8 (57%) due to anatomic constraints, 4 (29%) due to stapes fixation, and 2 (14%) due to middle ear space and/or mastoid inflammatory disease. CONCLUSIONS Premature termination in surgery for CAA is a rare occurrence with careful study of the preoperative high-resolution computed tomography of the temporal bone. Of the reasons for premature termination, anatomic constraints were the most common. Knowing limitations in surgery-both technical and anatomic-is critical to optimize outcomes and prevent complications.

Pain is a major public health problem, causing heavy social and economic burdens to patients and society while consuming tremendous medical resources at the same time. Thus, there is a critical need to find low-cost, efficacious, and therapeutic approaches to help manage pain. While acupuncture is increasingly recognized as a promising pain-relieving method, less is known about a specific form of auricular acupuncture known as Battlefield Acupuncture (BFA). The BFA technique involves the sequential placement of semi-permanent, single-use, French ASP[Formula: see text] golden needles to five specific acupoints in one or both ears, where they are left in place for 3–4 days or longer [Niemtzow, R.C., Battlefield acupuncture. Med. Acupunct. 19: 225–228, 2007]. The BFA needles (more accurately described as tiny conical darts) pierce the ear in designated locations in a particular order [Levy, C.E., N. Casler and D.B. FitzGerald. Battlefield acupuncture: an emerging method for easing pain. Am. J. Phys. Med. Rehabil. 97: e18–e19, 2018.]. (Figs. 4 and 5) It was developed by Dr. Richard C. Niemtzow in 2001, as a subgroup form of an auricular acupuncture technique based on the somatotopic arrangement of an inverted fetus pattern on the external ear [Romoli, M. Ear acupuncture: historical abstract–differences of ear cartography between the east and the west. Dtsch. Z. Akupunkt. 53: 24–33, 2010.]. Currently, BFA is widely used in the US military, but to our knowledge, there is no review which comprehensively synthesizes the current publications surrounding pain management. This review aims to investigate the effects and safety of BFA in adults with pain. Electronic databases were searched for randomized controlled trials (RCTs) published in English evaluating efficacy and safety of BFA in adults with pain, from database inception to September 6, 2019. The primary outcome was pain intensity change, and the secondary outcome was safety. Nine RCTs were included in this review, and five trials involving 344 participants were analyzed quantitatively. Compared with no intervention, usual care, sham BFA, and delayed BFA interventions, BFA had no significant improvement in the pain intensity felt by adults suffering from pain. Few adverse effects (AEs) were reported with BFA therapy, but they were mild and transitory. BFA is a safe, rapid, and easily learned acupuncture technique, mainly used in acute pain management, but no significant efficacy was found in adult individuals with pain, compared with the control groups. Given the poor methodological quality of the included studies, high-quality RCTs with rigorous evaluation methods are needed in the future.

Bear attacks, although rare, can inflict life-threatening injuries. We present the case of a 50-y-old woman from rural Pennsylvania who was attacked by a North American black bear, Ursus americanus. She sustained multiple complex injuries including near-complete scalp avulsion, bilateral ear avulsions, and fractures of the face, ribs, and pelvis. These injuries are similar to those sustained in other bear maulings reported in the literature and required both acute intervention and a multidisciplinary approach to recovery.

Bonebridge is an suitable option for conductive hearing loss, however, the traditional approach cannot accomplished a satisfying implantation for patients with congenital malformation or radical mastoidectomy.To evaluate the clinical application of retrosigmoid sinus approach in Bonebridge implantation and postoperative evaluation.11 patients who underwent retrosigmoid sinus approach Bonebridge implantation from March 2016 to September 2019 were retrospectively analyzed, including 6 males and 5 females, aged 12-54 years old (30.6 in average). Among them, 4 cases had undergone bilateral radical mastoidectomy, 6 cases had bilateral congenital aural atresia or stenosis, and 1 case had unilateral congenital aural atresia.All patients underwent Bonebridge implantation through retrosigmoid sinus approach according to the preoperative image reconstruction and plan. There was no surgical injury of sigmoid sinus or cerebrospinal fluid leakage during the operation. The aided threshold obtained an increase of 32.32 dB HL; the speech recognition rates of bisyllabic words, monosyllabic words and sentence were 79.6%, 67.8% and 75.0%, respectively. After 11-53 months of follow-up, the hearing effect was stable and no long-term complications occurred.The retrosigmoid sinus approach is an effective surgical approach for patients with congenital ear deformities or radical cavity after mastoidectomy.

Objectives The objective of this study was to describe wideband absorbance (WBA) findings in patients with cholesteatomas and retraction pockets (RPs). Design In this prospective study, tympanometry, audiometry, and wideband tympanometry (WBT) were performed on 27 ears with an RP (eight with epitympanic RP and 19 ears with mesotympanic RP), 39 ears with a cholesteatoma (23 ears with epitympanic and 16 ears with mesotympanic cholesteatomas [MCs]), and 49 healthy ears serving as controls. Results Mean WBA at ambient pressure (WBAamb) of both experimental groups was reduced significantly between 0.8 and 5 kHz relative to the control group. The difference between mean WBAamb and mean WBA at tympanometric peak pressure (WBATPP) was greater for the RP (0.12–0.16 between 0.5 and 1.5 kHz) than for the cholesteatoma group (0.03–0.11 between 0.6 and 3 kHz). Mean WBAamb of both epitympanic RP (ERP) and epitympanic cholesteatoma (EC) subgroups was significantly lower than that of the control group. Mean WBATPP of the ERP subgroup attained normal levels as per the control group, while mean WBATPP of EC subgroup was significantly lower than that of the control group at 0.8 to 1.5 kHz and 4 to 5 kHz. In contrast, both mesotympanic RP and MC subgroups demonstrated similar mean WBAamb and WBATPP values. No significant differences in WBAamb and WBATPP results between the RP and cholesteatomas groups were observed. Receiver operating characteristic (ROC) analyses indicated that the area under the ROC curve for distinguishing between the RP and cholesteatomas groups ranged from 0.44 to 0.60, indicating low accuracy in separating the two groups. Conclusion While it is not possible to distinguish between the RP and cholesteatomas groups based on the WBAamb and WBATPP results, it is potentially feasible to differentiate between the EC and ERP conditions. Further study using a large clinical sample is recommended to determine the sensitivity and specificity of the WBA test to identify the EC and ERP conditions.

Detailed studies have not been conducted on sound localization and speech perception in noise in patients with unilateral congenital aural atresia (UCAA).To evaluate the benefits of the use of the Vibrant Soundbridge (VSB) for UCAA by performing audiometric and sound localization tests.Four children with UCAA underwent VSB (VORP 503) implantation from 2018 to 2019. Speech perception tests in noise were conducted using the Japanese monosyllable test. The spatial configuration for speech testing consisted of speech presented from the front and noise presented into the normal ear (SThe children's speech perception in noise 6 months after VSB activation was significantly better than before activation (The benefits of VSB use in children with UCAA were revealed using audiometric and sound localization tests.

Recurrent nerve laryngeal schwannoma is a rare benign tumor that, in expert hands, can be treated by transoral CO2 laser surgery.

ObjectivesThe objective of this descriptive review was to determine the quality, readability, and suitability of ear and hearing health information and materials for patients and their significant others.MethodA literature search was conducted between August 2018 and April 2019 in the databases CINAHL Complete, MEDLINE, and PsychInfo. Inclusion and exclusion criteria were used to shortlist studies. Data regarding quality, suitability, and readability were extracted from the included studies. Data were assessed qualitatively.ResultsThere were 34 studies included in this review. Of those, eight examined quality, 33 assessed readability, and four investigated the suitability of materials. The range of materials assessed included diagnostic reports, patient education materials (PEMs), patient-reported outcome measures, and websites. Quality elements were examined in studies focusing on website information. Findings indicated that most websites were of poor quality. Suitability was examined in studies focusing on PEMs such as hearing aid user guides. Findings indicated that most of the existing materials were not suitable for the intended populations. The reading grade level of information across all four categories was found to be higher than the recommended fifth or sixth reading grade level for health-related materials. Revisions of some diagnostic reports and PEMs showed that improvements are possible.ConclusionsThis review suggests that ear- and hearing-related materials generally have lower quality and suitability with higher readability (more difficult to read). Development of materials that are suitable, of high quality, and at the appropriate readability levels is required to improve accessibility of ear- and hearing-related materials.

Olfactory neuropathy spectrum disorder is characterized by hyposmia or anosmia and hypoplastic or absent olfactory bulbs. There may be an association between olfactory neuropathy spectrum disorder and Wolff‐Parkinson‐White syndrome.

Background: Traditionally, patients are seen by an ear, nose and throat (ENT) surgeon prior to allied health referral for treatment of swallowing, voice, hearing and dizziness. Wait-times for ENT consultations often exceed those clinically recommended. We evaluated the service impact of five allied health primary contact clinics (AHPC-ENT) on wait-times and access to treatment. Setting: A metropolitan Australian University Hospital Outpatient ENT Department. Participants: We created five AHPC-ENT pathways (dysphonia, dysphagia, vestibular, adult and paediatric audiology) for low-acuity patients referred to ENT with symptoms of dysphonia, dysphagia, dizziness and hearing loss. Main outcome measures: Using multiple regression analysis, we compared waiting times in the 24-month pre- and 12-month post-implementation of the AHPC-ENT service. In addition, we measured the number of patients requiring specialist ENT intervention after assessment in the AHPC-ENT, adverse events and evaluation of service delivery costs. Results: Seven hundred and thirty-eight patients were seen in the AHPC-ENT over the first 12 months of implementation (dysphagia, 66; dysphonia, 153; vestibular, 151; retro-cochlear, 60; and paediatric glue ear, 308). All pathways significantly reduced the waiting times for patients by an average of 277 days, compared with usual care. The majority of patients were able to be discharged without ongoing ENT intervention (72% dysphagia; 81% dysphonia; 74% vestibular; 53% retro-cochlear; and 32% paediatric glue ear). No adverse events were recorded. Conclusions: The AHPC-ENT improved waiting times for assessment and access to treatment. Future research on cost-effectiveness and diagnostic agreement between AHPs and ENT clinicians would provide further confidence in the model.

BACKGROUND This study aimed to develop a novel temporal bone squamous cell carcinoma (TBSCC) prognosis scoring system and compare it with the revised Pittsburgh staging system. METHODS Forty-four consecutive TBSCC patients were assessed to identify predictors of recurrence. Each predictor's hazard ratio for recurrence was used to develop our novel scoring system. RESULTS Based on variables with P

Objectives: Veterans Health Administration encourages auricular acupuncture (Battlefield Acupuncture/BFA) as a nonpharmacologic approach to pain management. Qualitative reports highlighted a “gateway hypothesis”: providing BFA can lead to additional nonpharmacologic treatments. This analysis examines subsequent use of traditional acupuncture. Research Design: Cohort study of Veterans treated with BFA and a propensity score matched comparison group with a 3-month follow-up period to identify subsequent use of traditional acupuncture. Matching variables included pain, comorbidity, and demographics, with further adjustment in multivariate regression analysis. Subjects: We identified 41,234 patients who used BFA across 130 Veterans Health Administration medical facilities between October 1, 2016 and March 31, 2019. These patients were matched 2:1 on Veterans who used VA care but not BFA during the same period resulting in a population of 24,037 BFA users and a comparison cohort of 40,358 non-BFA users. Patients with prior use of traditional acupuncture were excluded. Results: Among Veterans receiving BFA, 9.5% subsequently used traditional acupuncture compared with 0.9% of non-BFA users (P

STATEMENT OF PROBLEM: Implant-retained auricular prostheses, on a bar-clip or with a magnetic retention system, are considered successful treatment for missing ears. However, which of these 2 retention systems is preferred by patients is unknown.PURPOSE: The purpose of this clinical study was to assess which retention system is mostly preferred by patients wearing implant-retained auricular prostheses: bar-clip retention or magnetic retention.MATERIAL AND METHODS: All consecutive patients visiting the clinic between March 2014 and November 2014 for a routine follow-up of their implant-retained auricular prostheses on a bar-clip retention system were asked to enroll in this descriptive study comparing patient preference for the retention system: bar-clip versus magnets. Participants were asked to complete a questionnaire to obtain patient satisfaction scores regarding their auricular prosthesis before and 3 months after changing to a magnetic-retained auricular prosthesis. After 3 months, participants were asked to state their preference for either their previous bar-clip system or the new magnetic system. If they did not prefer the magnetic system, participants were able to return to their previous bar-clip system. The study follow-ups were performed at 6, 12, 24, and 36 months. Again, patient satisfaction was scored with the aid of the same questionnaire, and prosthetic care and aftercare were also assessed.RESULTS: Of 20 eligible patients, 17 participants (12 men, 5 women) enrolled in the study. The mean score for patient satisfaction for the bar-clip system at the start of the study was high (8 ±1.62). After 3 months, 2 participants wanted to return to their previous bar-clip system, followed by 1 more at the 6-month evaluation and 2 more at the 1-year evaluation. After 3 years, 9 of 16 participants (57%) preferred the magnetic-retained auricular prosthesis. During the 3 years of follow-up, aftercare was considered minor for both the bar-clip and the magnetic system. No participants developed peri-implantitis. All participants indicated that cleaning and placing the magnetic-retained auricular prosthesis was easier than the bar-clip system.CONCLUSIONS: The majority of the participants (59%) in this study, especially the elderly participants, preferred the magnetic retention system. When compared with the bar-clip system, no additional aftercare was needed.

Available data on dichotic listening using tonal Chinese words have been limited, and conflicting results on a right-ear advantage (REA) have been reported. The current study developed a set of Mandarin CV-words based on the Bergen dichotic listening paradigm.The test materials consisted of two sets of stimuli. The English set, derived from the iDichotic application, consisted of six nonsense syllables with plosives conjugated to /a/. The Mandarin set had these 6 CV-syllables spoken as real words according to the Mandarin phonology.The mean difference of correct recognition responses between two ears indicated a REA with both sets of stimuli for the right-handers, but not for left-handers. For the right-handers, performance with the Mandarin set was significantly better than performance with the English set. Dichotic listening with the Mandarin set had strong correlation between two time points,Performance using the Mandarin set is reliable in dichotic listening; a REA is observed for the right-handers.

Objectives: To analyze the data of patients with otorhinolaryngological foreign bodies and to evaluate the management and outcomes of foreign bodies to prevent complications. Methods: A retrospective study was conducted over 8 years at Aseer Central Hospital to examine all admitted cases with foreign bodies in the ear, nose, throat, esophagus and bronchus during the period from January 2011 to January 2019. Patient demographic data, type of foreign body, and most common site were analyzed. Results: A total of 184 patients were admitted, including 72 (39.1%) males and 112 (60.9%) females. The age range was from one year old to 70 years old; the mean±standard deviation of age was 10.6±12.55 years. Foreign bodies were most commonly located in the esophagus (n=97, 52.7%), followed by the bronchus (n=55, 29.9%). A statistically significant difference was found, with a p-value of 0.00001. The most common site in children was the bronchus (n=39, 21%); the most common site in adults was the esophagus (n=18, 72%). Conclusion: Otorhinolaryngological foreign bodies are found most frequently in preschool-aged children. The most common site in children was the bronchus, and the most common site in adults was the esophagus. Prevention measures are essential to reduce the risk of ingestion and admission, which can be challenging.

Background. Although Botulinum Toxin Type A (BTXA) has been applied to scar prevention and treatment, the mechanisms still require further exploration. Objective. To investigate the effects of BTXA on microvessels in the hypertrophic scar models on rabbit ears. Methods. Eight big-eared New Zealand rabbits (males or females) were selected to establish scar models. One ear of each rabbit (4 models in each ear) was selected randomly to be injected with BTXA immediately after modeling and included in the treated group, while the opposite ear was untreated and included in the control group. The growth of scars in each group was observed and recorded, and 4 rabbits were sacrificed on days 30 and 45 after modeling. Then, scar height was measured by hematoxylin-eosin (HE) staining, vascular endothelial growth factor (VEGF) expression was detected by immunohistochemical (IHC) testing, and microvessel density (MVD) was calculated based on CD34 (human hematopoietic progenitor cell antigen). Results. The wounds in each group were well healed and free from infection or necrosis. On days 30 and 45, the scar height, MVD value, and VEGF expression in the treated group were lower than those in the control group (P<0.05). For the treated group, the above indicators on day 45 were lower than on day 30 (P>0.05). Besides, there was a positive correlation between the MVD value and the VEGF expression in the treated group (P<0.05). Conclusion. The injection of BTXA immediately after modeling inhibits VEGF expression and reduces angiogenesis, thereby inhibiting hypertrophic scar formation.

Objective: To evaluate the long-term safety and efficacy of the Clip coupler attached to the stapes head in patients with unilateral congenital aural atresia (CAA). Methods: This single-center retrospective study included 16 Mandarin-speaking patients who had unilateral microtia accompanied by CAA. All patients were divided into two groups: the short-term follow-up group (n = 9) and the long-term follow-up group (n = 7). The floating mass transducer of the Vibrant Soundbridge (VSB) was positioned in the stapes head by the Clip coupler. The safety of the VSB was investigated by comparing preoperative and postoperative bone-conduction (BC) thresholds as well as by complications. The effectiveness was evaluated by functional gain (FG), word recognition score (WRS), speech reception threshold (SRT) and signal-to-noise ratio (SNR). Results: Pre- and post-operative BC thresholds were no different in all patients. And no complications developed. VSB-aided thresholds in the free-field had improved significantly in both short- and long-term follow-up groups. The improvements of WRS were observed in two groups. The monosyllabic VSB-aided WRS in the long-term follow-up group was significantly higher than that in the short-term follow-up group. When speech was from the impaired ear and noise presented to the side of normal ear (SVSBNCL), lower SNRs were found in two groups after VSB implantation. However, there was no statistical difference in aided SNR between the two groups at SVSBNCL status. Conclusions: Our results show that the FMT connected to the stapes head is a secure and useful device for patients with unilateral CHL/MHL, not only in terms of improved hearing thresholds, but also improved speech intelligibility in quiet and noisy environments.

This study compared the language, reading, classroom, and quality of life outcomes of primary school-aged children with aural atresia (AA) to matched controls. Participants included 10 children with AA (eight unilateral) and 10 children with typical hearing matched by chronological and mental age. All children with AA had been fitted with an amplification device. Outcome measures included standardized tests of language, reading, and functional communication questionnaires of children’s classroom performance and hearing quality of life. The children with AA recorded significantly reduced hearing quality of life. The two groups did not differ on any other measures. The present preliminary findings suggest that children with AA who receive early amplification have similar language, communication, reading, and classroom outcomes as their typically hearing peers. Despite these promising outcomes, however, the children’s quality of life is significantly reduced. Further research is needed to further elucidate these findings.

Malignant otitis externa (MOE) is a rare and potentially life-threatening disease of the ear and temporal bone. Bilateral simultaneous MOE is extremely rare. Due to bilaterally symmetrical facial nerve palsy, it can easily be missed at the initial presentation, causing delay in management. Here, we report a case of bilateral MOE managed aggressively with regular ear toileting, ear packing with a ribbon gauze soaked with topical antimicrobials, and long-term intravenous and oral antibiotics. The patient showed good improvement in pain control, facial nerve status, and ear findings.

OBJECTIVE Describe long-term trends and stability of hearing outcomes for patients undergoing primary congenital aural atresia (CAA) repair. STUDY DESIGN Retrospective chart review. SETTING Single academic, tertiary referral center. PATIENTS Children and adults who underwent primary CAA repair between 1980 and 2017. INTERVENTION CAA repair. MAIN OUTCOME MEASURES Long-term (> 1 yr) postoperative three-tone (500, 1000, 2000 Hz) air conduction pure-tone average (AC PTA) compared with the immediate (within 90 d of surgery) postoperative audiogram. RESULTS The mean preoperative AC PTA was 59.6 dB HL. CAA repair improved hearing an average of 30.5 dB, but hearing declined by 8.2 dB over the long-term follow-up period (mean 4.4 yr; range 1-15.7 yr), leaving a final mean improvement of 22.2 dB (final mean AC PTA 37.3 dB HL). Two-thirds (92 of 138 ears) had an AC PTA ≤ 30 dB HL recorded in the first year after surgery. At the last follow-up test, 64% had "stable" hearing defined as no more than a 10 dB decline in AC PTA compared with the immediate postoperative audiogram; 21% had a 10 to 20 dB decline, 8% a 20 to 30 dB decline, and 7% declined > 30 dB. CONCLUSIONS All patients enjoyed improvement in AC PTA after surgery (preoperative minus the best postoperative PTA, mean = 34 dB, range = 3.3-52 dB). Hearing declined by an average 8.2 dB over the long-term leaving a final average AC PTA of 37.4 dB HL. Sixty-four percent of patients exhibited stable (< 10 dB loss) hearing over time; 36% lost 10 dB or more over the long-term follow-up period. Hearing results typically stabilize over time with most of the change occurring in the first 3 years after CAA repair. Bone conduction thresholds remained stable over the study period.

We examined the language and reading progress of 336 young DHH children in kindergarten, first and second grades. Trained assessors tested children’s language, reading, and spoken and fingerspelled phonological awareness in the fall and spring of the school year. Children were divided into groups based on their auditory access and classroom communication: a spoken-only group (n = 101), a sign-only group (n = 131), and a bimodal group (n = 104). Overall, children showed delays in language and reading compared to norms established for hearing children. For language, vocabulary standard scores were higher than for English syntax. Although delayed in language, children made expected gains based on hearing norms from kindergarten to second grade. Reading scores declined from kindergarten to second grade. Spoken-only and bimodal children had similar word reading and reading comprehension abilities and higher scores than sign-only children. Spoken-only children had better spoken phonological awareness and nonword reading skills than the other two groups. The sign-only and bimodal groups made similar and significant gains in ASL syntax and fingerspelling phonological awareness.

OBJECTIVES: This study aims to characterize lateralization of sounds and localization of sounds in children with bilateral conductive hearing loss (BCHL) when listening with either one or two percutaneous bone conduction devices (BCDs). DESIGN: Sound lateralization was measured with the minimum audible angle test in which children were asked to indicate from which of the two visible speakers the sound originated. Sound localization was measured with a test in which stimuli were presented from speakers that were not visible to the children. In the sound localization test, 150 ms broadband noise bursts were presented, and sound level was roved over a 20-dB range. Because speakers were not visible the localization response was not affected by any visual cue. The sound localization test provides a clear distinction between lateralization and localization of sounds. Ten children with congenital BCHL and one child with acquired BCHL participated. RESULTS: Both lateralization and sound localization were better with bilateral BCDs compared with the unilaterally aided conditions. In the bilateral BCD condition, lateralization was close to normal in nearly all the children. The localization test demonstrated lateralization rather than sound localization behavior when listening with bilateral BCDs. Furthermore, in the unilateral aided condition, stimuli presented at different sound levels were mainly perceived at the same location. CONCLUSIONS: This study demonstrates that, in contrast to listening with two BCDs, children demonstrated difficulties in lateralization of sounds and in sound localization when listening with just one BCD (i.e., one BCD turned off). Because both lateralization and sound localization behavior were tested, it could be demonstrated that these children are more able to lateralize than localize sounds when listening with bilateral BCDs. The present study provides insight in (sub-optimal) sound localization capabilities of children with congenital BCHL in the unilateral-aided and bilateral-aided condition. Despite the sub-optimal results on sound localization, this study underlines the merits of bilateral application of BCDs in such children.In patients with congenital bilateral conductive hearing loss (BCHL), bilateral application of bone conduction devices (BCDs) is not the standard treatment (Liu et al. 2013). Based on systematic reviews of the existing literature, several authors have concluded that more studies are needed to provide convincing evidence on the advantage of bilateral BCD application over listening with a unilateral BCD (Colquitt et al. 2011; Janssen et al. 2012; Johnson et al. 2017). Patients with BCHL cannot access binaural cues when listening with only one BCD. With two BCDs, these patients may gain increased access to binaural cues, allowing for improved localization abilities (Zeitooni et al. 2016). Binaural processing of our auditory world provides important benefits like, improved directional hearing, increased safety (Stelling-Kończak et al. 2016), feelings of comfort and understanding of speech in noisy listening conditions (Avan et al. 2015). Hence, it is important to provide patients with BCHL and their caretakers with evidence on the merits of hearing rehabilitation with two BCDs.

Group B Streptococcus (GBS) vertical transmission causes fetal and neonatal colonization and diseases. However, there is scarcity of data in low-income countries including Ethiopia. We conducted a cross-sectional study on 98 GBS positive mothers, and their newborns to find proportion of vertical transmission. GBS was identified from swabs by using recommended methods and vertical transmission at birth was confirmed by the culture of body surface swabs of newborns within 30 minutes following birth. GBS positivity among swabbed specimens collected for other purposes was 160/1540 (10.4%); 98 were from 385 recto-vaginal swabs of pregnant women, and 62 were from 1,155 swabs of the 385 births. Of the 98 GBS positive cases, 62 newborns were GBS colonized with vertical transmission proportion of 63.3%(95% CI: 54.1–72.4%). We identified that the proportion of vertical transmission in this study was within the range of other many global studies, but higher than recently published data in Ethiopia. Maternal educational level, employment and lower ANC visit were significantly associated risk factors to GBS vertical transmission. Efforts need to be made to screen pregnant women during antenatal care and to provide IAP to GBS positive cases to reduce mother to newborn vertical transmission.

Background Necrotizing soft tissue infection of the ear following ear piercing is a very rare condition. It is easily misdiagnosed leading to reconstructive morbidities and mortality in neonates. High clinical suspicion is important for early diagnosis. Our knowledge, this is the first case reported in the literature in this unique initial presentation. We hope to heighten the awareness of necrotizing soft tissue infection of the ear following ear piercing to ensure early aggressive intervention. Case presentation We report a set of 19-day-old female twin neonates who developed bilateral ear sores following ear piercing in a primary healthcentre without adherence to surgical asepsis. Examination findings showed features consistent with necrotizing soft tissue infections of the ears. They were successfully managed with antibiotics and wound care. Conclusion Necrotizing soft tissue infections is a very rare complication of neonatal ear piercing. It may occur following suboptimal aseptic procedure and a high index of suspicion is necessary to make this diagnosis to ensure early intervention and to forestall the potential reconstructive morbidities and mortality associated with late recognition. Adherence to basic aseptic surgical principles is the key to prevention of necrotizing soft tissue infections.
