From vertigo to hearing loss, here’s what to know about this inner ear disorder.
Doctors usually begin with a hearing test to check for loss in one ear. Patients wear headphones and respond to various tones and volumes to measure how well they hear. Some tests check the ability to distinguish between similar sounds. To evaluate balance, a common test is electronystagmography (ENG). During ENG, electrodes placed around the eyes track involuntary eye movements as warm and cool water are introduced into the ears. Abnormal responses may indicate inner ear dysfunction.
