NIDCD Research on EVA and Hearing Loss

NIDCD scientists examine a CT scan

The NIDCD’s Otolaryngology Branch is conducting a clinical research study on hearing loss associated with enlarged vestibular aqueducts (EVA). The researchers are recruiting individuals with EVA and hearing loss—and their relatives—to participate in an ongoing study.

Participants usually will need to travel to the NIH Clinical Center in Bethesda, Md. (just outside Washington, D.C.), for 2 to 3 days of evaluations. The evaluations typically include a physical examination, hearing tests, imaging of the inner ears, studies of the thyroid, and genetic testing to identify any underlying genetic causes for EVA and hearing loss. The NIDCD is usually able to subsidize participants’ lodging and food costs.

More information on this observational study is available from ClinicalTrials.gov.
