A New Methodology for Evaluation of Large Vestibular Aqueduct Syndrome in CT and MRI Images: Defining the Syndrome and Finding Clinical Correlation

HYPOTHESIS: The goal of the research is to propose criteria to define large vestibular aqueduct (LVA)/large endolymphatic sac anomaly (LESA) using our previously developed method based on analysis of CT/CBCT and MRI, and to propose a new classification of the clinical course of hearing loss. BACKGROUND: Previous studies did not provide results that would conclusively relate audiological and radiologic data.

Audiologists should be aware of this proposed new imaging framework for defining LVAS and large endolymphatic sac anomaly, but clinical adoption should await validation in independent cohorts before changing diagnostic practice.

Standardising radiological criteria for large vestibular aqueduct syndrome has direct implications for diagnosis, counselling, and management of paediatric and adult patients with unexplained sensorineural hearing loss.
