Abstract

Idiopathic sudden sensorineural hearing loss(SNHL) is defined as a sensorineural hearing loss which develops over a period of hours or few days without a definitive causes. The etiology, prognosis, and treatment of SNHL are uncertain. We reviewed records of 76 patients to investigate the efficacy of the stellate ganglion block(SGB)in SNHL. The control group(40 patients) was managed with the medication such as hypaque, heparin, steroid, nicotinic acid, and vitamine. The SGB group(27 patients) was managed with the same medication and SGB (1~2 times/day). The efficacy of treatment was evaluated by mean dB of 500, 1000, 2000 Hz on follow up pure tone audiogram. Recovery rate above 15dB was not different between SGB and the control group (52.4 v.s. 52.0%), though SGB group has much poor prognostic factors. Recovery rate was higher in a case that was treated early. Especially, the recovery rate was 100% when SGB begins within 2 weeks from the onset. Headache and profound type of audiogram were poor prognostic factors. In conclusion, SGB within 2 weeks from the onset is recommanded to improve the recovery rate.

1) 돌발성난청의 치료성적은 대조군, 성상신경절차 단군 각각 완전회복 28.6%, 18.5%, 부분회복은 6.1%, 7.4%, 경도회복은 16.3%, 25.9%로 성상신경절차단군이 예후가 나쁜 인자가 많았음에도 불구하고 두군사이에 유의한 차이가 없었다. 2) 회복예후는 두통이 수반될 때, 청력형이 농형일 때 예후가 불량하였고, 발증에서 치료시작까지의 기간이 빠를수록 좋았으며 특히 성상신경절차단을 2주 이내에 시행한 경우에는 반응이 없었던 예가 없었다.
