title: Enlarged vestibular aqueduct syndrome mimicking otosclerosis in adults.
abstract: BACKGROUND
  An enlarged vestibular aqueduct (EVA) results in hearing loss which is often progressive and heterogenous, the long-term natural history of which is not well understood. Patients born before the era of newborn hearing screening can present as adults with previously undiagnosed EVA.
  
  
  METHODS
  A retrospective chart review of patients seen at a tertiary adult academic otologic clinic from 2004 to 2012 were reviewed and cases of EVA were identified.
  
  
  RESULTS
  Adult EVA was found to present with a mixed progressive hearing loss with absent stapedial reflexes.
  
  
  CONCLUSIONS
  Enlarged vestibular aqueduct abnormality can present in adulthood and mimic other more common pathology such as otosclerosis.
