Objective: Management of tympanic membrane perforations is varied. This study aimed to better understand current practice patterns in myringoplasty and type 1 tympanoplasty. Methods: An electronic questionnaire was distributed to American Academy of Otolaryngology – Head and Neck Surgery members. Practice patterns were compared in terms of fellowship training, practice length, practice setting, paediatric case frequency and total cases per year. Results: Of the 321 respondents, most were comprehensive otolaryngologists (60.4 per cent), in private practice (60.8 per cent), with a primarily adult practice (59.8 per cent). Fellowship training was the factor most associated with significant variations in management, including pre-operative antibiotic usage (p = 0.019), contraindications (p < 0.001), approach to traumatic perforations (p < 0.001), use of local anaesthesia (p < 0.001), graft material (p < 0.001), tympanoplasty technique (p = 0.003), endoscopic assistance (p < 0.001) and timing of post-operative audiology evaluation (p = 0.003). Conclusion: Subspecialty training appears to be the main variable associated with significant differences in peri-operative decision-making for surgical repair of tympanic membrane perforations.

Objective: To determine if otolaryngologists and audiologists of the American Academy of Otolaryngology – Head and Neck Surgery have noticed an increase in the incidence of sudden sensorineural hearing loss during the coronavirus disease 2019 pandemic. Methods: A questionnaire was developed for the purpose of providing a cross-sectional descriptive analysis of perceived association between the coronavirus disease 2019 pandemic and an increase in the incidence of sudden sensorineural hearing loss. Results: Of respondents, 63.0 per cent did not notice an increase in sudden sensorineural hearing loss during the coronavirus disease 2019 pandemic. There was a weak positive correlation between patients identified with sudden sensorineural hearing loss and the percentage of coronavirus disease 2019 positive patients reported by each medical care provider (Spearman correlation = 0.20, 95 per cent confidence interval = 0.05–0.33). There was no association between geographical location and perceived increase in sudden sensorineural hearing loss (p = 0.38). Conclusion: The majority of respondents did not perceive an increase in the incidence of sudden sensorineural hearing loss during the coronavirus pandemic, regardless of geographical region.

Objective: This study aimed to examine the medical literature regarding the natural history and management of keratosis obturans. Method: PubMed was queried via the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol, and the methodological quality of each study was assessed using the Methodological Index for Non-Randomized Studies criteria. Results: Fifty-one studies were abstracted, and dual investigator screening resulted in five retrospective studies for final analysis. All studies included patients afflicted with either unilateral (n = 75) or bilateral keratosis obturans (n = 8). The definition of keratosis obturans was present in three studies: a desquamated keratin plug within the external auditory canal. Mean and median Methodological Index for Non-Randomized Studies scores were 9.5 and 9.5, respectively. All patients underwent keratosis obturans exenteration with microscopy. Two studies reported an outcome instrument to evaluate endpoints: marked stillette and audiometry. No complications were observed with follow-up periods from 3 weeks to 3.5 years. Conclusion: This comprehensive review highlights a lack of published evidence relating to keratosis obturans. However, it appears keratosis obturans treatment is safe and efficacious with identifiable clinical practice patterns. [ABSTRACT FROM AUTHOR]

Objectives:To identify and evaluate cranial magnetic resonance imaging findings associated with Ménière's disease.Methods:Seventy-eight patients with a documented diagnosis of Ménière's disease and 35 controls underwent 1.5 T or 3 T magnetic resonance imaging of the brain. Patients also underwent otological, vestibular and audiometric examinations.Results:Lack of visualisation of the left and right vestibular aqueducts was identified as statistically significant amongst Ménière's disease patients (left, p = 0.0001, odds ratio = 0.02; right, p = 0.0004, odds ratio = 0.03). Both vestibular aqueducts were of abnormal size in the Ménière's disease group, albeit with left-sided significance (left, p = 0.008, odds ratio = 10.91; right, p = 0.49, odds ratio = 2.47).Conclusion:Lack of vestibular aqueduct visualisation on magnetic resonance imaging was statistically significant in Ménière's disease patients compared to the general population. The study findings suggest that magnetic resonance imaging can be useful to rule out retrocochlear pathology and provide radiological data to support the clinical diagnosis of Ménière's disease.

Background:Benign paroxysmal positional vertigo and migraine-associated dizziness are common. The prevalence of benign paroxysmal positional vertigo seems to be higher in patients with migraine-associated dizziness than in those without migraine.Methods:A database of 508 patients seen at the primary author's balance clinic was analysed to determine the prevalence of migraine, as defined by International Headache Society criteria, in patients with benign paroxysmal positional vertigo.Results:The percentage of patients with dizziness or vertigo who met criteria for migraine was 33.7 per cent, with a prevalence of benign paroxysmal positional vertigo of 42.3 per cent. When excluding patients with migrainous vertigo, patients with migraine frequently had benign paroxysmal positional vertigo (66.7 per cent vs 55.8 per cent), although this finding was not statistically significant.Conclusion:The results for the entire sample suggest that, after excluding patients with migrainous vertigo, patients with migraine seem more likely to have benign paroxysmal positional vertigo; however, this association was not significant, probably because of the small sample size.

Background:Histopathological anomalies of inner-ear structures in individuals with Down syndrome have been well documented; however, few studies have examined the radiological features.Methods:A retrospective study was conducted of temporal bone computed tomography images in 38 individuals (75 ears) with Down syndrome to evaluate the prevalence of inner-ear abnormalities and assess vestibular aqueduct widths.Results:Inner-ear anomalies were identified in 20 of the 38 individuals (52.6 per cent). Seven of the 75 temporal bones (9.3 per cent) were found to have higher than previously reported. A dilated internal auditory canal and vestibule were more common among the present study group, while prior studies have demonstrated internal auditory canal stenosis and decreased vestibule size.Conclusion:Down syndrome patients exhibit a high prevalence of dysplastic inner-ear features that confer substantial risk of sensorineural hearing loss. Computed tomography is a useful screening aid to detect inner-ear abnormalities, particularly enlarged vestibular aqueducts, which cause preventable sensorineural hearing loss in this population.

Objectives: This study aimed to describe outcomes of paediatric stapes surgery at an academic tertiary care centre., Methods: Electronic medical records of patients younger than 21 years who underwent stapedotomy between September 2013 and July 2020 were reviewed., Results: A total of 17 patients (7 male, 10 female) were included in our study; 14 underwent surgery on one ear while 3 underwent surgery on both ears (20 ears total). Mean pre-operative air-bone gap was 34.5 dB (standard deviation, 11). At three months, the mean post-operative air-bone gap was 20.6 dB (standard deviation, 10.2), with a mean improvement of 17 dB (standard deviation, 12.1). Sixty-four per cent of patients had closure of their air-bone gap to 20 dB or less. A negative correlation between pre-operative body-mass index and post-operative air-bone gap was statistically significant (n = 14, p = 0.03, r = -0.57 [95% confidence interval -0.85, -0.04])., Conclusion: Paediatric stapedotomy can be effective and safe. In this cohort, age was not correlated with improvement in air-bone gap; pre-operative body mass index was significantly correlated with post-operative air-bone gap.
