Introduction: The purpose of this study was to investigate whether patient, tumor and radiation therapy factors are associated with development of middle ear effusion (MEE) in nasopharyngeal carcinoma (NPC) patients. Methods: A retrospective review of NPC patients treated between January 2000 and June 2018 at Rabin Medical Center. Patient factors, tumor factors, radiation doses and radiation fields were collected and outlined if needed (middle ear, eustachian tube (ET), tensor veli palatini (TVP) and levator palatini (LVP) muscles), then analyzed and compared between patients with MEE and those without and between sides in patients with unilateral MEE. Results: 73 patients were enrolled. Most were males (71.2%) with advanced stage diseases (78%). At the time of diagnosis 14 patients (19.2%) presented with MEE and in 18 (24.6%) patients post radiation MEE was observed (15 ipsilateral to the tumor and 3 bilateral). Tumor stage, histology and laterality were not associated with development of MEE. Comparison of mean radiation field dosages including - gross target volume (GTV), clinical target volume (CTV) and patient target volume (PTV) showed no association with post radiation MEE. In addition, no difference was found in the radiation doses to the middle ear, ET or the LVP nor the TVP between ears with and without MEE. Conclusions: Postirradiation MEE remains a common adverse effect in NPC patients. Surprisingly, tumor stage, tumor laterality and histology were not associated with MEE. Similar findings were observed for total radiation doses and specific doses to the middle ear, ET and ET muscles.

Tumor satellites are defined as islands of tumor cells completely separated from the border of the main tumor. They are believed to be a sign of aggressive disease. Our goal was to investigate the association between tumor satellites and outcome in patients with oral squamous cell carcinoma.A retrospective analysis of all patients treated for oral squamous cell carcinoma at a university-affiliated tertiary care center between 2010 and 2018 was performed. Data collected included demographics, clinical and pathological features including tumor satellites, staging, treatment modalities, and outcomes.A total of 144 patients were included. The mean age of all patients was 63.5 and 50.7% were males. The mean follow-up time was 40.5 months. Seventeen patients (11.8%) had tumor satellites. These patients had a higher rate of involved margins, peri-neural invasion, lympho-vascular invasion, and extra-nodal extension. Tumor, nodal and overall classification were significantly more advanced in patients with satellites. Disease-specific and overall survival rates were significantly lower among satellites patients (28.7% vs. 59.7% and 28.7% vs. 54.9%, respectively).Tumor satellites are associated with several adverse features and advanced locoregional disease. Patients with satellites should be treated aggressively with a combination of surgery aimed at achieving free surgical margins and adjuvant treatment, as they have a worse prognosis compared with patients without satellites. Further prospective studies are mandatory to consolidate the importance of adjuvant treatment in these patients.3 Laryngoscope, 2022.

Surgical navigation technology combines patient imaging studies with intraoperative real-time data to improve surgical precision and patient outcomes. The navigation workflow can also include preoperative planning, which can reliably simulate the intended resection and reconstruction. The advantage of this approach in skull-base surgery is that it guides access into a complex three-dimensional area and orients tumors intraoperatively with regard to critical structures, such as the orbit, carotid artery and brain. This enhances a surgeon’s capabilities to preserve normal anatomy while resecting tumors with adequate margins. The aim of this narrative review is to outline the state of the art and the future directions of surgical navigation in the skull base, focusing on the advantages and pitfalls of this technique. We will also present our group experience in this field, within the frame of the current research trends.

An international survey was conducted to investigate the preferences for completion lymph node dissection (CLND) in head and neck melanomas.A questionnaire was sent through the American Society of HeadNeck Surgery (AHNS) and Canadian Society of Otolaryngology-Head and Neck Surgery (CSO).Hundred and forty-nine surgeons completed the survey. Response rate was 6.3% and 9.7% from AHNS and CSO members, respectively. When presented the scenario of a 47-year-old male with a clinical T3bN0 cheek melanoma, with 1/1 positive sentinel lymph node (SLN) with nodal deposit2 mm, 72 of respondents (48.3%) would perform a CLND. Reasons for CLND included multiples positive SLN (64.1%), size of nodal deposits (54.2%), and perceived lack of compliance to follow-up (54.2%). Surgeons with access to immunotherapy treatment were less likely to recommend CLND (p = 0.025).Following SLN biopsy, nearly half of the surveyed head and neck surgeons would recommend CLND, which contrasts with the current melanoma practice patterns in other anatomic locations. However, compared with an earlier study in the literature it does seem that there has been a shift away from completion neck dissection. Further investigation into understanding practice variations is warranted.

purpose: The purpose of this study was to evaluate whether induction of temporary threshold shift (TTS) with aspirin prior to cisplatin exposure can prevent or minimize cisplatin detrimental effects on hearing.Methods: We randomly divided BALB mice into three groups: ]1[ cisplatin only, ]2[ aspirin only, and ]3[ combined aspirin/cisplatin. Cisplatin was administered as a single intraperitoneal injection of 14 mg/kg. Aspirin was administered for three weeks via intraperitoneal injection of 200 mg/kg sodium salicylate, twice daily. Air conduction thresholds were recorded using Auditory Brainstem Responses (ABR). Cochleae were harvested and cochlear hair cells were counted using a scanning electron microscope (SEM).Results: Aspirin-induced TTS have reached an average of 30.05±16.9 dB after two weeks. At 60 days, cisplatin-only treated mice experienced an average threshold shifts of 50.7 dB at 4 kHz, 35.16 dB at 8 kHz, 70dB at 16 kHz, 53.1 dB at 32 kHz. All threshold shifts were significantly worse than for cisplatin/aspirin treated mice with TTS of 11.85 dB at 4 kHz, 3.58 dB at 8 kHz, 16.58 dB at 16 kHz, 20.41dB at 32 kHz (pConclusion: Aspirin induced TTS can protect from cisplatin-induced ototoxicity. This beneficial effect was demonstrated by auditory thresholds as well as SEM. Larger pre-clinical and clinical studies are still needed to confirm these findings.

Purpose: Osteomyelitis of the cervical spine and skull base are rare, devastating complications of radiotherapy for head and neck cancer. The study evaluated patient characteristics, risk factors and described the disease course and management. Material and methods: A clinical case series from a tertiary cancer center. We conducted a retrospective review of the medical files from 2012 to 2021, including clinical characteristics, treatment, and outcome data. Descriptive statistics were applied. Results: Nine patients (78% male) with post-radiation cervical osteomyelitis were reviewed. Median patient age was 68 years. The maximal radiation dose was 61.71Gy. The mean delay in diagnosing osteomyelitis was 6.32 years from the first radiotherapy course and 2.9 years from the last period. Sites affected were the cervical vertebrae (6 patients) and the clivus, clavicle, and sternum (1 patient each). The main symptoms were dysphagia and cervicalgia (55%). A medical or surgical event preceded the diagnosis in 6 patients (66%) by a mean of 51.33 days. Common imaging findings were free to air within the cervical structures and fluid collection. Cultures grew mainly typical polymicrobial flora. Treatment consisted of surgery and antibiotics or long-term broad-spectrum intravenous antibiotics alone. Eight patients have recovered from osteomyelitis during the follow-up within an average of 100 days. Five patients have died during the follow-up period. Conclusion: Post-radiation osteomyelitis is characterized by a subtle presentation, challenging diagnosis, prolonged treatment, and poor outcome. Clinicians should maintain a high index of suspicion for the long term after radiotherapy. Multidisciplinary evaluation and management are warranted.

Objective There is limited information regarding the recurrence patterns and efficacy of surveillance modalities in patients with sinonasal malignancies. Methods A retrospective study was conducted between the years 2001–2018 at a tertiary care center. Included were all patients with sinonasal malignancies treated in our institution. Data regarding recurrence and survival were analyzed. Results Eighty-one patients were included. Multimodal treatment was administered to the majority of patients. 24 (35.3%) patients recurred with a median time of 17 months (range, 4–180). Although the majority of recurrences occurred within the first 5 years (83.3%), 4 (16.6%) recurred later on (5−15 years). Recurrences were local in 83.3%, regional in 20.8% and distant in 16.6%. All local recurrences occurred within the radiation treatment field and all patients with distant failure had mucosal melanoma. The majority of recurrences (70.6%) were diagnosed clinically or endoscopically, mainly in patients with SCC during the first 2 years of follow up. MRI or PET-CT were crucial in detecting extra-sinus and distant failures. Salvage surgery was feasible in the majority of patients (58.3%). Overall, 5 years survival (OS) rate was 60.9%. Conclusions Frequent clinic visits with nasal endoscopy combined with frequent imaging studies should be routinely practiced as part of a long-term surveillance plan. Longer follow up duration should be considered in these patients.

Several studies have reported that younger children suffer from increased incidence and more severe episodes of acute mastoiditis (AM) than older children, whereas other researchers have found the opposite. The aim of our study was to describe the occurrence, clinical, and microbiological aspects of AM in children 6 months or younger, and compare them with the results in an older reference age band. The medical files of children hospitalized with a diagnosis of AM during 2001–2016 were retrospectively reviewed. Diagnosis of AM was based on the presence of clinical signs of acute otitis media (AOM) accompanied by two or more of the following: auricle protrusion, retro-auricular erythema, swelling, and local tenderness. Children were divided into two age bands, 6 months or younger, and older than 6 months. Fifty patients in the young age band and 335 in the older reference age band were included. Bilateral AOM was identified in 14 (28%) children under 6 months, and 50 (14.9%) in the reference age band (p

Positive margins have been reported up to 80% in advanced maxillary cancers. Intraoperative navigation (IN) aims to improve margins, but provides a two-dimensional view of a registered instrument without anticipating any cutting directions, and the information is displayed in monitors outside surgical field. Augmented Reality (AR) can delineate margins while addressing the gaze-toggling drawback of IN. In a preclinical setting, we implemented preoperative-planned osteotomies needed for maxillectomies and projected this information on the surgical field using AR. We aimed to improve negative margin rates while retaining the benefits of AR.Five maxillary tumor models were built. Five fellowship-trained surgeons completed virtual unguided and AR-guided maxillectomies. Comparisons in terms of intratumoral cuts, close, adequate, and excessive distances from the tumor were performed. Differences between "ideal" cutting-plan and the AR-guided virtual osteotomies was obtained. Workload questionnaires to evaluate the technology were completed.115 virtual osteotomies were analyzed. Intra-tumoral and "close" margins were lower for the AR-assisted osteotomies (0.0% vs 1.9% p 0.0001 and 0.8% vs 7.9% p 0.0001). Proportion of "adequate" margins were higher in the AR simulations (25.3% vs 18.6%, p = 0.018). The AR osteotomies had high similarity with the pre-planned with interclass correlation index close to 1 in "adequate" margins 0.893 (95% CI: 0.804-0.949). Workload scores were better for AR-guided simulations for the domains of mental demand, performance, effort and frustration.The projector-based AR method improved margin delineation, and preoperative planning was accurately translated to the simulations. Clinical translation will aim to consolidate our preclinical findings to improve outcomes.

Background: The role of intra-operative parathyroid hormone (IOPTH) monitoring during parathyroidectomy for primary hyperparathyroidism has long been debated. Objectives: Our main goal was to investigate the cure rates of parathyroidectomy for primary hyperparathyroidism with and without IOPTH monitoring. Our secondary goal was to investigate if operating room time can be saved when not using IOPTH monitoring. Design: A retrospective analysis of patients who underwent parathyroidectomy for PHPT for a single adenoma between 2004-2019 was performed. Cure rates and operating room time were compared. Results: 423 patients were included. IOPTH was used in 248 patients (59%). Four patients were not cured, two from each group, with no significant difference between the groups (98.8% vs. 99.1%, p=0.725). Surgery time was significantly longer in the IOPTH group, p

Objectives:The aim of this study was to investigate the audiometric outcomes of tympanomastoidectomy in children with cholesteatoma and to evaluate factors that may affect outcomes.Methods:A retrospective cohort study was conducted. All pediatric patients diagnosed with cholesteatoma who underwent primary canal wall-up tympanomastoidectomy with or without ossicular reconstruction from 2009 to 2016 at a tertiary university-affiliated pediatric medical center were included. Pure tone average (PTA) and air-bone gap (ABG) at 0.5, 1, 2, and 4 kHz were compared before and after surgery.Results:The cohort included 100 children (104 tympanomastoidectomies) of mean age 10.35 ± 3.6 years. The mean duration of follow-up was 35.4 ± 24.1 months. At surgery, 22 patients (21.2%) had intact ossicular chains, and 82 (78.8%) had ossicular discontinuity. Fifty-three patients (51%) underwent ossicular reconstruction, either partial (34 patients [64.1%]) or total (19 patients [35.8%]). In comparison with preoperative audiometry, there was a statistically significant improvement in PTA-ABG at the first postoperative examination (27.5 ± 12.7 vs 21.1 ± 11.1 dB, P = .001) and at the end of follow-up (20.2 ± 12.7 dB, P = .003) . Overall, values of less than 20 dB were measured in 34% of patients preoperatively and 73% postoperatively. On subgroup analysis, in patients who underwent any ossicular reconstruction, PTA-ABG was significantly improved relative to the preoperative value (28.1 ± 14.7 dB) at both the first (19.1 ± 11.9 dB, P = .006) and last (22.4 ± 15.1 dB, P = .011) audiometry examinations.Conclusions:Hearing outcomes after pediatric cholesteatoma surgery are diverse and related to several factors. The authors found that ossicular reconstruction improves audiometric outcomes, and the changes remain stable over time.Level of Evidence:IIB

Background There is uncertainty regarding the effectiveness of tonsillectomy for recurrent tonsillitis in the adult population. Several studies have described a reduced number and severity of tonsillitis episodes; however, the impact of tonsillectomy on healthcare burden has yet to be studied. The aim of the present study was to evaluate the long-term outcomes of tonsillectomy in the adult population. Methods A retrospective review of the central database of Clalit Health Services, Tel Aviv, Israel, between 2003 and 2009 was performed. The study included all adult patients (>18 years) who underwent tonsillectomy due to recurrent tonsillitis. Clinical and epidemiological data from 3 years before and after surgery were collected and analyzed. Results A total of 3,701 patients were included in the study. Mean age was 37.4 years, and 42.9% were males. Following surgery, there was a significant decrease in the total number of tonsillitis episodes, otolaryngologist clinic visits, consumption of pertinent antibiotics, and respiratory complaints. Moreover, a reduced number of hospitalizations to the otolaryngology department and shorter hospitalization duration were also noted. Although the total number of hospitalizations was unaffected, there was an increase in the number of primary care office visits. Finally, a break-even time analysis revealed an average of 2.7 years following tonsillectomy. Conclusion Tonsillectomy for recurrent tonsillitis is effective in decreasing the number and severity of tonsillitis episodes and might also have an economic benefit. The impact of tonsillectomy on general health needs to be further evaluated; however, it appears that there is no increase in overall morbidity. Level of evidence NA Laryngoscope, 130:328-331, 2020.

Non-echo-planar diffusion weighted magnetic resonance imaging (Non-EPI DWI MRI) is commonly used for follow-up after cholesteatoma surgery. MRI has a critical role in the evaluation of residual disease, where physical examination will commonly demonstrate an intact tympanic membrane. The aim of our study was to assess the timing of residual cholesteatoma identification on serial MRI scans and the yield of MRI follow up after canal wall up tympano-mastoidectomy.A retrospective chart review of children that underwent canal wall up tympano-mastoidectomy due to cholesteatoma in Schneider Children's Medical Center during 2004-2016, and were followed up both clinically and with MRI.Seventy-seven children (89 ears) were included, who altogether underwent 166 surgeries (77 revisions). Average follow-up was 66 ± 34.4 months. During follow up, 244 scans were performed; 19 cases of residual disease were diagnosed by MRI and confirmed in surgery. The mean time from surgery and an MRI positive for residual disease was 29.7 ± 16 months (range: 10-66). In 9/19 cases (47%), at least one negative MRI preceded the scan positive for residual disease, and in 4 cases at least two initial scans were negative.MRI plays an important role in the diagnosis of residual disease after cholesteatoma surgery. In our cohort. Almost half of the cases diagnosed with residual disease had at least one negative scan prior to the positive one, emphasizing the importance of close radiological follow-up with serial scans after surgery.

To investigate complication rates in elderly cancer patients undergoing major head and neck surgeries.A retrospective, matched-control, analysis. For each elderly (≥70 years) patient, a younger, (70 years) patients were matched based on sex, tumor location, disease stage, and operation time. Post-operative complication and survival analyses were performed.Of 225 patients, 75 (33.3%) were elderly (mean age 76.2 (70-88) years) and compared with a match control group (53.2 (23-69) years). A higher rate of cardio-vascular comorbidity was noted in the elderly group (70.6% vs. 34%, respectively, P 0.001). The majority (62.7%) of elderly patients required reconstruction with 24% receiving vascularized flap reconstruction. Total postoperative complication rate was 49.9% in the study versus 42.3% in the control group, with a major complication rate of 22.5% in the elderly versus 11.9% in the control group (P = 0.154). Mean follow-up was 41 (0-144) months. Five-year disease-specific (67.1% vs. 80.7%, P 0.001) and overall survival rates (48.6% vs. 75.4%, P 0.001) were significantly lower among elderly patients.Major head and neck surgery in the elderly population does not entail higher complication rate, compared with younger patients, and should be allowed when curative intent is feasible and patient's general condition allows.

Several studies have reported that younger children suffer from increased incidence and more severe episodes of acute mastoiditis (AM) than older children, whereas other researchers have found the opposite. The aim of our study was to describe the occurrence, clinical, and microbiological aspects of AM in children 6 months or younger, and compare them with the results in an older reference age band.The medical files of children hospitalized with a diagnosis of AM during 2001-2016 were retrospectively reviewed. Diagnosis of AM was based on the presence of clinical signs of acute otitis media (AOM) accompanied by two or more of the following: auricle protrusion, retro-auricular erythema, swelling, and local tenderness. Children were divided into two age bands, 6 months or younger, and older than 6 months.Fifty patients in the young age band and 335 in the older reference age band were included. Bilateral AOM was identified in 14 (28%) children under 6 months, and 50 (14.9%) in the reference age band (p 0.001). Fever, mean WBC, and CRP values were similar in both age bands; 4 (8%) children under 6 months had pre-auricular/zygomatic area swelling, as compared to 1(0.02%) in the reference age band (p 0.001). Complication rates (subperiosteal abscess, sinus vein thrombosis, and epidural abscess) were similar in both age bands. All children were treated with myringotomy and IV antibiotics. Cortical mastoidectomy with the insertion of ventilation tube was performed in 10 (20%) children in the younger age band and 58(17.3%) in the reference age band. Streptococcus pneumoniae was the most common (38%) isolated bacteria in the younger age band, and Group A streptococcous (GAS) (20.6%) in the reference age band.AM in children 6 months or younger has similar presentation and characteristics as in older children. Pre-auricular swelling and bilateral AOM are more typical in the younger age band; Streptococcus pneumoniae is the most common pathogen in the younger children. We suggest that the treatment approach should be the same for both groups.

In this retrospective cohort study of 1716 cases of women undergoing infertility treatment between the years 1999-2012, we aimed to identify whether parturients with a previous surgical history are at a higher risk for tubal abnormalities as determined by hysterosalpingography (HSG) in this infertile population. Amongst the study population, tubal obstruction was identified on HSG in 15.8% of patients with no past history of an abdominal surgery and 16.3% of patients with a previous caesarean section (CS) delivery. These rates were significantly lower than those for women with a previous gynaecological surgery (34.7%) or abdominal surgery (27%) (p .001 for all comparisons). Our results suggest that past history of CS poses no additional risk for tubal abnormality within the infertile population, whereas a history of other abdominal or gynaecological surgical procedures doubles this risk. Impact Statement What is already known on this subject? While numerous risk factors for tubal factor infertility have been established, to date, the relation between previous abdominal surgeries and the risk for tubal factor infertility remains inconclusive. What the results of this study add? In this study, we aimed to evaluate the correlation between previous CS history and the risk for having tubal factor infertility. Our results demonstrated that previous caesarean section delivery does not increase the risk for tubal factor infertility in the infertile population, whereas history of other abdominal or gynaecological surgical procedures doubles this risk. What the implications are of these findings for clinical practice and/or further research? Further research is needed for further evaluation of this association and its clinical implications.

Objective Epistaxis is a common complaint, yet few studies have focused on the incidence and risk factors of recurrent epistaxis. Our objective was to determine the patterns of incidence and risk factors for recurrent epistaxis admission (REA). Study Design Case series with chart review. Settings Single academic center. Subjects and Methods The medical records of patients admitted for epistaxis between 1999 and 2015 were reviewed. The follow-up period was defined as 3 years following initial admission. REAs were categorized as early (30 days) and late (31 days to 3 years) following initial admission. Logistic regression was used to identify potential predictors of REAs. Results A total of 653 patients were included. Eighty-six patients (14%) had REAs: 48 (7.5%) early and 38 (6.5%) late. Nonlinear incidence curve was demonstrated for both early and late REAs. Based on logistic regression, prior nasal surgery and anemia were independent risk factors for early REAs. According to multivariate analysis, thrombocytopenia was significantly associated with late REAs. Conclusion Early and late REAs demonstrate different risk predictors. Knowledge of such risk factors may help in risk stratification for this selected group of patients. All patients at risk should be advised on possible preventive measures. Patients at risk for early REA may benefit from a more proactive approach.

Objective To determine if the clinical behavior of T1 glottic squamous cell carcinoma varies by its location on the medial free edge or upper aspect of the vocal cords. Study design Retrospective cohort. Setting Single tertiary university-affiliated medical center. Subjects and methods Clinical, treatment, and outcome data were collected for 104 patients with T1N0M0 glottic squamous cell carcinoma who were treated and followed at our center in 1995–2013. Findings were compared between those with a tumor on the medial ( n = 60, 57.7%) or superior ( n = 44, 42.3%) aspect of the cords. Results Mean follow-up time was 4.15 years. No between-group differences were found in demographic or risk factors. There was a significant association of anterior commissure involvement with disease recurrence ( P = 0.0012) and of superior (vs medial) location with higher rates of anterior commissure involvement ( P P = 0.01) and shorter time to recurrence ( P Conclusions T1 squamous cell carcinomas on the superior aspect of the vocal cords have a poorer prognosis than medial tumors and should be closely monitored for recurrence.

Introduction The incidence of head and neck melanoma is increasing. Various factors influence prognosis. Objective We sought to investigate the subgroup of patients with head and neck melanoma who fail primary treatment and to define the patterns of failure. Methods The database of a tertiary medical center was reviewed for patients diagnosed and surgically treated for cutaneous head and neck melanoma in 1995–2014. Regional disease failure was defined as disease confirmed in positive SLNB at first assessment or at recurrence. Results The cohort included 141 patients followed for a median duration of 6.8 years (range 1–20 years). Median tumor thickness was 2.1 mm (range 0.5–12 mm). Ulceration was documented in 38 patients (26.9%). Sentinel lymph node biopsy (SLNB) was positive in 18 patients (12.8%). Total disease failure rate was 32.6% with similar rates of regional (n = 26, 18.4%) and distal (n = 22, 15.6%) failure. Most patients (86.3%) with systemic recurrence had a negative SNLB as did 6/26 patients (23%) with regional failure. Forty-three patients (30.4%) died during follow-up, half of them (23 patients, 16.3%) of melanoma. On multivariate analysis, Breslow thickness was the only significant predictor of outcome. Conclusions The pattern of treatment failure in patients with head and neck melanoma relate predominantly to Breslow thickness. The high false-negative rate of SNLB and the relatively high rate of systemic failures in patients with negative SNLB indicate a low predictive value of this procedure. Efforts to detect systemic disease during follow-up need to be intensified.

Fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) has been increasingly used in the past decade. Incidental FDG-avid findings are encountered in these studies, several of which with clinical significance. However, the significance of incidental FDG-avid sinonasal findings has not been studied to date.Retrospective cohort study.A single tertiary medical center.The medical records were reviewed of patients with incidental sinonasal positive FDG uptake between 2007 and 2016 who referred for further otolaryngological diagnostic workup.A total of 26 patients were identified, all of whom underwent a diagnostic surgical procedure. Histopathology revealed chronic inflammation (n = 12, 46.1%), malignancy (n = 7, 26.9%), inverted papilloma (n = 4, 15.5%), and fungal infections (n = 3, 11.5%). A unilateral maxillary sinus with FDG uptake was documented for 16 (61.5%) patients. CT evidence of bilateral disease and mucosal or sinus wall thickening correlated with inflammatory disease.Incidental lesions with positive FDG uptake in the sinonasal cavities are at a high risk (40%) of being neoplastic. A diagnostic biopsy is advocated in these cases.

Background: Head and neck patients are prone to malnutrition. Perioperative fluids administration in this patient group may influence nutritional status. We aimed to investigate perioperative changes in patients undergoing major head and neck surgery and to examine the impact of perioperative fluid administration on body composition and metabolic changes using bioelectrical impedance. Furthermore, we sought to correlate these metabolic changes with postoperative complication rate. In this prospective observational pilot study, bioelectrical impedance analysis (BIA) was performed preoperatively and on postoperative days (POD) 2 and 10 on patients who underwent major head and neck surgeries. BIA was completed in 34/37 patients, mean total intraoperative and post-anesthesia fluid administration was 3682 ± 1910 mL and 1802 ± 1466 mL, respectively. Total perioperative fluid administration was associated with postoperative high extra-cellular water percentages (p = 0.038) and a low phase-angle score (p &lt, 0.005), which indicates low nutritional status. Patients with phase angle below the 5th percentile at POD 2 had higher local complication rates (p = 0.035) and longer hospital length of stay (LOS) (p = 0.029). Multivariate analysis failed to demonstrate that high-volume fluid administration and phase angle are independent factors for postoperative complications. High-volume perioperative fluids administration impacts postoperative nutritional status with fluid shift toward the extra-cellular space and is associated with factors that increase the risk of postoperative complications and longer LOS. An adjusted, low-volume perioperative fluid regimen should be considered in patients with comorbidities in order to minimize postoperative morbidity.

Background Recurrent periorbital cellulitis (RPOC) associated with rhinosinusitis is rarely noted and scarcely discussed in the literature. The aim of our study was to analyze the characteristics and disease course of a group of pediatric patients with RPOC. Methods The medical records of all pediatric patients with a diagnosis of RPOC treated in a tertiary children's hospital were retrieved. Included were patients with a history of two or more episode of RPOC. Results A total of 14 children were included. Mean follow up was 3 years (SD ± 2.5). Median age of first POC episode was 12 months (range 5 months–12 years). Overall, 75 events of RPOCs were documented. A median of 3 events per patient was noted (range 2–16). Preseptal cellulitis was diagnosed in all but five patients, in whom orbital cellulitis or subperiosteal abscess were identified, one following failure of conservative treatment, and the remaining at first presentation or recurrence. Rhinorrhea was present in only five patients (35%). The majority of patients were treated with intra-venous antibiotics. Imaging studies were performed in all patients revealing ethmoidal sinusitis in all patients, with lamina papyracea dehiscence in two patients. Immune deficiency was diagnosed in one patient. Endoscopic sinus surgery was performed in seven patients, in four as preventive procedure and in three during an acute phase. Post-operative recurrent disease was noted in two patients that were operated during the acute phase. Conclusions RPOC is a rare entity. Rhinosinusitis should be suspected in events of recurrent preseptal cellulitis even in the absence of nasal symptoms. CT scan is diagnostic for sinus origin of disease and possible anatomical abnormalities. In the majority of patients no evident etiology was identified. Elective Surgery or prophylactic antibiotic treatment should be strongly considered in this subgroup of patients as it seems beneficial.

BACKGROUND: Endoscopic sinus surgery (ESS) is often recommended for symptomatic patients with recurrent acute or chronic rhinosinusitis who have failed conservative treatment. Postoperative care has been felt to be critical for both maintaining the surgical patency of the operated sinuses and improving patient symptoms. Debridement of the sinonasal cavities is one such postoperative care measure that has frequently been studied in the literature, often with conflicting conclusions. OBJECTIVES: To assess the effects of postoperative sinonasal debridement versus no debridement following endoscopic sinus surgery. SEARCH METHODS: The Cochrane ENT Information Specialist searched the ENT Trials Register; Central Register of Controlled Trials (CENTRAL, via the Cochrane Register of Studies); PubMed; EMBASE; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 21 May 2018. SELECTION CRITERIA: Randomised controlled trials comparing postoperative nasal debridement versus no debridement in adult patients with recurrent acute or chronic rhinosinusitis undergoing endoscopic sinus surgery. We included studies in which the patients acted as self‐controls (i.e. one side of the nose underwent debridement and the other side did not) only for the secondary endoscopy outcomes. DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by Cochrane. Our primary outcome measures were: health‐related quality of life, disease severity (patient‐reported symptom scores) and significant adverse effects (bleeding requiring intervention, severe pain, iatrogenic injury). Secondary outcomes were: postoperative endoscopic appearance of the sinonasal surgical cavities (endoscopic scores), recorded use of postoperative medical treatment and rate of revision surgery. We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics. MAIN RESULTS: We included four studies (152 participants), with a follow‐up duration ranging from three months to 12 months. In two studies patients acted as self‐controls, i.e. one side of the nose underwent debridement and the other side did not ('split‐nose' studies). The risk of bias in all studies was high, mostly due to the inability to blind the patients to the debridement procedure. Primary outcomes Disease‐specific health‐related quality of life scores Only one study (58 participants) provided data for disease‐specific health‐related quality of life. At six months follow‐up, lower disease‐specific health‐related quality of life scores, measured using the Sino‐Nasal Outcome Test‐22 (SNOT‐22, range 0 to 110), were noted in the debridement group but the difference was not statistically significant (9.7 in the debridement group versus 10.3 in the control group, P = 0.47) (low‐quality evidence). Disease severity (patient‐reported symptom score) Only one study (60 participants) provided data for disease severity measured by visual analogue scale (VAS) score. No significant differences in total symptom score were observed between groups postoperatively (low‐quality evidence). Significant adverse effects Significant adverse effects related to the debridement procedure were not reported in any of the included studies, however it is not clear whether data regarding adverse effects were not collected or if none were indeed observed in any of the included studies. Secondary outcomes All four studies assessed thepostoperative endoscopic appearance of the sinonasal cavities using the Lund‐Kennedy score (range 0 to 10). A pooled analysis of endoscopic scores in the two non 'split‐nose' studies revealed better endoscopic scores in the debridement group, however this was not a statistically significant difference (mean difference ‐0.31, 95% confidence interval (CI) ‐1.35 to 0.72; I² = 0%; two studies; 118 participants) (low‐quality evidence). A sub‐analysis of the adhesion formation component of the endoscopic score was available for all four studies and revealed a significantly lower adhesion rate in the debridement group (risk ratio 0.43, 95% CI 0.28 to 0.68; I² = 29%; four studies; 152 participants). Analysis of the number needed to treat to benefit revealed that for every three patients undergoing debridement, the endoscopic score would be decreased by one point in one patient. For every five patients undergoing debridement adhesion formation would be prevented in one patient. Use of postoperative medical treatment was reported in all studies, all of which recommended nasal douching. Steroids (systemic or nasal) were administered in two studies. However, the data were very limited and heterogeneous, therefore we could not analyse the impact of concomitant postoperative medical treatment. The rate of revision surgery was not reported in any of the included studies, however it is not clear whether these data were not recorded or if there were no revision surgeries in any of the included studies. AUTHORS' CONCLUSIONS: We are uncertain about the effects of postoperative sinonasal debridement due to high risk of bias in the included studies and the low quality of the evidence. Sinonasal debridement may make little or no difference to disease‐specific health‐related quality of life or disease severity. Low‐quality evidence suggests that postoperative debridement is associated with a significantly lower risk of adhesions at three months follow‐up. Whether this has any impact on longer‐term outcomes is unknown.

Introduction Survival rates of solid organ transplant recipients are steadily increasing. Chronic immunosuppression is a key to sustain the transplanted organ. Thus, these patients are at a higher risk for fulminant disease and severe complications of rhinosinusitis (RS). Surprisingly, this has been scarcely discussed in the literature. Objective To analyze the characteristics and disease course of RS in solid organ transplant recipients. Materials and Methods Retrospective study. Medical records of all solid organ transplant recipients with a diagnosis RS treated at a national transplant center between the years 2001 and 2016 were reviewed. Results Of 4562 solid organ transplant recipients, a documented diagnosis of RS was identified only in 61 (1.3%) patients. Sixty-four patients presented with posttransplantation RS; of them, 54.5% had chronic RS (CRS) and the remaining 45.5% patients were diagnosed with acute RS. Microbial cultures grew almost exclusively bacterial pathogens. A documented invasive fungal infection was noted in only 2 patients. A total of 24 (40%) patients underwent endoscopic sinus surgery, the majority (22) for CRS. On subgroup analysis, surgical intervention was more frequent in lung transplant recipients ( P = .005). Neither specific disease nor surgical complications were found. Conclusions Interestingly, acute fulminant infection or sinusitis complications in solid organ transplant patients were much lower than expected. CRS in this patient group was less frequent than expected as well. Whether chronic immunosuppression minimizes the likelihood for CRS deserves further investigation. A more surgically oriented approach in CRS patients may be favored early in the management course of medically refractory patients in light of patients excellent outcomes.

Ultrasonography (US) is a reliable tool for the preoperative localization of parathyroid adenomas (PTAs). The aim of this study was to evaluate the accuracy of US for estimating both the size and the location of PTAs and the effect of operator expertise.Retrospective cohort study.A single tertiary medical center.All patients who underwent parathyroidectomy for primary hyperparathyroidism between 1996 and 2012 were included. The estimated PTA localization and size by preoperative ultrasound were compared with the intraoperative findings and pathology report.The cohort included 410 patients. US correctly localized the adenoma in 76% of cases with a sensitivity of 76.2% and a positive predictive value of 86.8%. Measurements were least accurate for adenomas measuring1 cm in diameter (24%). Scans made by a single senior operator specializing in the neck had a higher accuracy rate than scans made by multiple operators, with a significant difference for small adenomas ( P.001).US is an accurate and sensitive tool for evaluating PTA size and location. Neck US is less accurate for small adenomas (1 cm). In these cases particularly, the experience and expertise of the US operator may play an important role.

Atypia/follicular lesion of unknown significance (AUS/FLUS) has variable rates of malignancy. The recommended management includes active surveillance (AS), repeated fine-needle aspiration (RFNA), diagnostic surgery, or genetic testing for malignancy. The objective of this study was to assess the management of AUS/FLUS patients in a dedicated thyroid clinic without implementing genetic testing.This was a single institute cohort study of all patients aged ≥18 years who underwent ultrasound-guided FNA thyroid biopsies between January 2009 and January 2013 and were followed until January 2016. The median follow-up time was 4.6 years (range 3.2-6.8 years). Forty-eight (57%) patients were referred to AS, and 36 (43%) patients were referred for diagnostic surgery. Thirty-six (75%) patients from the AS group underwent RFNA. An additional eight patients from the AS group subsequently underwent diagnostic surgery.Malignancies were found in 15/44 (34%) diagnostic surgical samples, and benign cytologies were found in 61.1% of the RFNAs. Analysis of adherence to follow-up in the 36 AS patients showed an adherence rate of only 53%, with males tending to comply better than females did (31.6% vs. 5.8%, respectively; p = 0.052), especially males in their sixth decade of life.Genetic tests for AUS/FLUS patients are accepted today as complementary evaluations in many well-developed health systems. Yet, when these tests are not feasible due to financial or availability issues, careful management of AUS/FLUS patients may still offer good results in the selection of patients for surgery or AS. The present results also indicate that compliance to follow-up schedules is a major consideration when selecting patients for AS.

Summary Objective To describe risk factors, clinical presentation, and outcome of patients with saccular disorders. Study Design Case control with chart review Methods A single center retrospective study. Case group included all adult patients, presenting with saccular disorders (saccular cyst or laryngocele), between the years 2010 and 2015. A matched group of patients with vocal fold cyst served as the control. Results Twenty-nine patients met the inclusion criteria: 15 males and 14 females; the mean age was 60.5(±11.2). The median follow-up period was 10 months (range 2–48). Overall, 75.9% (22) had a positive smoking history; 55.2% (16) were active and 20.7% (6) were past smokers. The median pack- years of all smokers in the saccular disorder group was 40 (range 1–67). Saccular disorder patients demonstrated significantly higher prevalence of active smoking when compared to control patients (55.2% versus 17.9%, P = 0.014). Sixty-nine percent of the patients had some synchronous vocal fold comorbidity. The leading vocal fold comorbidity was Reinke's edema in 41% (12). Synchronous vocal fold comorbidities were significantly more prevalent in smokers compared with nonsmokers—82% (18 of 22) and 29% (2 of 7), respectively ( P = 0.008). Surgical treatment was performed on 26 patients; all of whom underwent complete resection, either by endoscopic (92%), external (4%), or combined external and endoscopic (4%) approaches. There was a single case of recurrence (4%), 10 months following initial resection. Conclusion Saccular disorders are associated with smoking and synchronous vocal fold comorbidity. Complete resection is recommended as surgical outcome is excellent.

BACKGROUND Endoscopic sinus surgery (ESS) is often recommended for symptomatic patients with recurrent acute or chronic rhinosinusitis who have failed conservative treatment. Postoperative care has been felt to be critical for both maintaining the surgical patency of the operated sinuses and improving patient symptoms. Debridement of the sinonasal cavities is one such postoperative care measure that has frequently been studied in the literature, often with conflicting conclusions. OBJECTIVES To assess the effects of postoperative sinonasal debridement versus no debridement following endoscopic sinus surgery. SEARCH METHODS The Cochrane ENT Information Specialist searched the ENT Trials Register; Central Register of Controlled Trials (CENTRAL, via the Cochrane Register of Studies); PubMed; EMBASE; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 21 May 2018. SELECTION CRITERIA Randomised controlled trials comparing postoperative nasal debridement versus no debridement in adult patients with recurrent acute or chronic rhinosinusitis undergoing endoscopic sinus surgery. We included studies in which the patients acted as self-controls (i.e. one side of the nose underwent debridement and the other side did not) only for the secondary endoscopy outcomes. DATA COLLECTION AND ANALYSIS We used the standard methodological procedures expected by Cochrane. Our primary outcome measures were: health-related quality of life, disease severity (patient-reported symptom scores) and significant adverse effects (bleeding requiring intervention, severe pain, iatrogenic injury). Secondary outcomes were: postoperative endoscopic appearance of the sinonasal surgical cavities (endoscopic scores), recorded use of postoperative medical treatment and rate of revision surgery. We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics. MAIN RESULTS We included four studies (152 participants), with a follow-up duration ranging from three months to 12 months.

Gradual decrease in tube size and tube capping are considered the standard of care for tracheostomy decannulation. Both of these actions result in increased airway resistance. Immediate decannulation may offer a more tolerable approach.To assess the feasibility of immediate tracheostomy decannulation compared with the traditional decannulation methods.This study is a single institute, case-control retrospective study of patients between the years 2009 to 2014. The study group included all patients who underwent immediate decannulation, whereas the control group comprised patients who underwent traditional staged decannulation. An immediate decannulation protocol included admission to the intensive care unit, a comprehensive evaluation, decannulation, 24 hours of monitoring, and observation until discharge.Twenty-nine patients were included in the study group and 20 in the control group. No significant statistical difference was found between the two groups in the patients' medical history and tracheostomy data, except for the Acute Physiology and Chronic Health Evaluation II score and duration of the deflated cuff, which were significantly higher in the control group. A significant difference was found in the complication rate between the groups. In the staged decannulation group, four patients failed decannulation and required reinsertion of the tracheostomy cannula, whereas there were no such failures in the immediate decannulation group. Hospitalization duration after decannulation of the study group patients was significantly shorter than that of the control group.Immediate decannulation may offer a safe alternative for weaning from tracheostomy. It may also reduce the duration of the weaning process and hospitalization.3b Laryngoscope, 126:2057-2062, 2016.
