Abstract: We studied 150 patients with sudden deafness examined during the period of 1976 to 1992 to evaluate factors that may affect the prognosis for hearing recovery. All the patients were treated with dextram for about 10, 7 days and were evaluated by audiograms every day. The recovery rate was found to be favorable in younger patients (<40 years old), in those patients that had no vertigo and were treated within 10 days of onset. Patients with severe hearing loss (>4.5 dB) at the initial examination showed poor recovery. In this study the type of first audiogram did not influence recovery from sudden deafness.
