Acute Low-Tone Sensorineural Hearing Loss

With Nation-Wide Epidemiological Study of Sudden Deafness

Abstract

We examined acute low-tone sensorineural hearing loss from the results of nation-wide epidemiological study of sudden deafness in 1993. There were 252 patients with acute low-tone sensorineural hearing loss among 2, 790 patients. There were 168 wemen and 84 men. The age of patients was 34.8 years, that was 13.3 years younger than that of patients with sudden deafness. When the interval between the onset of the disease and the first visit to the hospital was short, prognosis was generally good.
