Abstract

Three cases of bilateral sudden deafness having simultaneous loss of hearing in both ears were reported. Whole course of deafness was observed in detail in case 1, and her hearing loss was improved to the normal level in both ears. In case 2, hearing loss was improved only in the left ear.
These results suggest that hearing loss in sudden deafness can be improved in fresh cases in binaural cases as well as in monaural cases.
In case 1, Coxsackie virus was identified in the cerebrospinal fluid. Then the authers discucced pat hogenesis of simultaneous bilateral sudden deafness and concluded that viral infection might play an important role particularly in bilateral cases.
