돌발성 난청 환자의 혈관 확장치료로서 histamine을 사용한 군과 SGB를 사용한 군을 회고적으로 비교한 결과 Histamine군에서는 19예 가운데 10예(52.8%), SGB군 30예 중 17예(56.1%)에 있어서 2~3주 이내에 개선을 보였다. SGB는 금기증이 거의 없으며 수기가 간단하고 부작용이 경미하므로 돌발성 난청의 치료에 있어서 histamine 치료의 좋은 대치 방법이 될 것으로 사료된다.
We compared the effectiveness of vasodilator therapy with histamine and stellate ganglion block(SGB) for the treatment of sudden sensoryneural hearing impairment retrospctively. 24 patients were treated with histamine and nicotinic acid(histamine group), and 30 patients were treated with SGB(SGB group). Corticosteroids and low molecular weight dextran($Rheomacrodex^{(R)}$) were given to all patients. The degree of hearing impairment and the evidence of improvement were checked with audiogram. 52.8%(10 out of l9 follow-up ckecked patients) of patients in histamine group and 56.7%(17 out of 30) of patients in SGB group had improved within three weeks of treatment, which means both histamine and SGB are equally effective. As a consequence, we concluded that SGB ia a good substitute for histamine as a vasodilator therapy for sudden sensoryneural hearing impairment with minimal complication, few absolute contraindications, and simple and safe technique.
