Fifty-six patients, treated with a series of anesthetizing blocks of the stellate ganglion for idiopathic sudden sensorineural loss, were compared with 20 patients of similar diagnosis who were treated by other means as to amount of pure-tone gain, speech discrimination improvement, nature of symptoms, and delay in start of surgery. Seventy percent of the stellate-ganglion-block-treated patients achieved substantial hearing improvement. Only 15% to 20% of the non-stellate-ganglion-block-treated patients achieved substantial hearing improvement in discrimination or pure-tone levels. The delay time from onset of symptoms to start of stellate block therapy appears to be important. The type of tinnitus, presence or absence of vertigo, and fullness in the ear may be useful prognostic signs.
56例因特发性突发性感音神经性听力损失接受星状神经节系列麻醉阻滞治疗的患者，与20例诊断相似但接受其他治疗方法的患者，在纯音增益量、言语辨别改善情况、症状性质以及手术开始延迟方面进行了比较。接受星状神经节阻滞治疗的患者中有70%听力得到显著改善。未接受星状神经节阻滞治疗的患者中，只有15%至20%在辨别力或纯音水平上听力得到显著改善。从症状出现到开始星状神经节阻滞治疗的延迟时间似乎很重要。耳鸣类型、是否存在眩晕以及耳部胀满感可能是有用的预后指标。
