A Clinicostatistical Study of the Sensorineural Deaf Patients


Abstract
373 cases of probable sensorineural hearing loss were selected for this statistical observation, among all outpatients visited to the Department of Otolaryngology of Seoul National University Hospital in 1977.
This disorder was found to be considerably wide in age distribution, though the highest incidence was seen among the twenties. Males were more affected than females.
In the majority of cases, the exact cause was unknown. In these cases, the type of hearing loss was either slowly-descending toward high-pitch sound, horizontal or steep-falling on high-pitch sound.
