Sudden Hearing Loss as an Initial Symptom of Vestibular Schwannoma.

Objective: This study aims to determine the prevalence of vestibular schwannoma (VS) among patients presenting with sudden hearing loss (SHL) and to characterize the clinical features of individuals diagnosed with both VS and SHL.

Methods: We conducted an observational retrospective review at a tertiary referral center, spanning a 30-year period, focusing on patients diagnosed with SHL where VS was confirmed as the underlying cause. We included patients meeting these criteria while excluding those lacking imaging or with a pre-existing diagnosis of VS.
