NIDCD Research on EVA and Hearing Loss

NIDCD's Otolaryngology Branch is conducting research on enlarged vestibular aqueducts (EVA) and hearing loss. The researchers are recruiting individuals with these problems—and their relatives—to participate in the ongoing study.

Participants must travel to the NIH Clinical Center in Bethesda, MD (just outside Washington, D.C.), for 2 to 4 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 cause of the EVA and hearing loss. NIDCD is usually able to subsidize participants' travel, lodging, and food costs.

More information on this study is available from ClinicalTrials.gov or the NIH Clinical Research Studies Web site. You can also search the NIH Clinical Studies Web site for information on other studies of EVA and hearing loss.
