Ménière’s disease is a progressive degenerative disease of the labyrinth. Its cause remains unknown. The disease presents with recurrent episodes of vertigo accompanied by ear symptoms (usually just on one side) of abrupt hearing loss, ear fullness, and tinnitus. These episodes can last hours and then spontaneously resolve. The time pattern is often erratic. The diagnosis is based partly on the clinical history, and partly on test results (usually an audiogram, electrocochleogram, and tests of vestibular function). Management includes prophylactic therapies (intended to prevent the episodes) and abortive therapies (treatments for individual episodes when they occur).
