Sudden Deafness; A Statistical Analysis of Ninety-Five Cases

Abstract

Ninety-five patients with sudden deafness were examined and treated at JA Yamaguchi Shuto General Hospital from 1982 to 1992, and their clinical data were analyzed statistically.
Prognostic factors were; time from onset of hearing loss to initiation of therapy; degree of hearing loss at the first examination; presence or absence of vertigo.
In regard to efficacy of therapy, we observed no significant correlation between age of onset and prognosis.
All patients were treated with several drugs and other forms of treatment. The effectiveness of steroids, alprostadil, dextran 40. lactated Ringer's solution, urokinase and stellate ganglion blocking was evaluated. Each was effective in some but not all patients, and no significant differances were noted among the therapuetic regimens.
