Forty-three patients with sudden low-tone (<500 Hz) sensorineural deafness (SLTD)were retrospectively studied. Thirty-four patients complained of tinnitus and ear fullness with hearing loss, while nine patients complained of deafness alone. Hearing recovered in about 60% of the patients, including three who showed spontaneous recovery. Recurrent attacks of temporary deafness were noted in six patients.
