Asymmetric Hearing Loss as a Population Screening Signal for Vestibular Schwannoma: A Number-Needed-to-Scan Analysis Using NHANES and SEER.
BACKGROUND Asymmetric sensorineural hearing loss (SNHL) is the principal audiometric trigger for magnetic resonance imaging (MRI) to exclude vestibular schwannoma (VS). Although multiple audiometric referral criteria exist, the population-level burden of applying them has not been quantified. OBJECTIVE To estimate ho...
