Background In sudden and asymmetrical progressive sensorineural hearing loss (SNHL), magnetic resonance imaging (MRI) is required to evaluate retrocochlear pathology and, with recent advances in MRI techniques, inner ear pathology. Given the limited literature regarding associated SNHL, we aimed assess incidence of pathology, congenital malformation on SNHL (SSNHL) SNHL. Methods A total 987 acoustic neuroma (AN) protocol internal meatus studies performed at our institution investigate between January 2013 December 2015 inclusive were identified. Following categorization for indication SSNHL versus MRIs or abnormality, other otology‐related abnormality identified, further data collected these patients including patient demographics, symptomatology, management outcomes. Results SSNHL, aetiological was identified 6.9% AN present 4% overall. 3.2% a causative lesion 2.3% scans overall diagnosing AN. The setting are 1.7% 0.6%, respectively. Conclusion This first retrospective study abnormalities both Australia one largest cohorts published date. must be ensure aforementioned rarer lesions
