Short-term outcome and prognosis of acute low-tone sensorineural hearing loss by administration of steroid

Acute low-tone hearing loss (ALHL) is a typical type of hearing loss in Meniere's disease and thought to be caused by endolymphatic hydrops in the inner ear. We treated 40 patients with ALHL by administration of the steroid and the early outcome and prognosis of the hearing level was retrospectively evaluated. The prognosis was generally determined within 7-10 days after administration of steroid. High-dose steroid cured some patients who failed to recover with low-dose steroid therapy. Our results showed that steroid is one of the effective therapies for ALHL and supported that etiology of ALHL involves an immune response. Copyright (C) 2002 S, Karger AG, Basel.
