다변량 분석에 의한 돌발성 난청의 임상적 특징과 예후 요인

Sudden deafness is defined as an abrupt onset of sensorineural hearing loss which develops over a period of hours or a few days and is thought to be otologic emergency that may causes permanent hearing loss and psychologic sequelae if not promptly treated. To investigate the clinical characteristics and its prognostic factors, 95 patients with sudden deafness admitted at aegu Fatima Hospital from January 1995 to December 2001 were selected. Hearing recovery rate was better in the ascending (81.8%) audiogram patterned group than in flat (61.5%), descending (37.5%) and deaf (8.3%) audiogram patterned group, and better in the age group below 59 (61.6%) than above 60 (23.1%), and better in the group without vertigo (68.1%) than with vertigo (23.1%). But there was no statistically significance in hearing recovery rate between the group treated within 1 week from onset of symptom and that group after 1 week. In multiple logistic regression analysis with age, the degree of hearing loss, the pattern of audiogram, the onset of treatment and vertigo, those variable significantly associated with negative prognosis were the descending audiogram pattern, late treatment and vertigo.
