We studied 28 patients with herpes zoster oticus prospectively over the six-year period between August 1974 and June 1980. We found that the results of measuring tear production, submandibular salivary flow, the response to maximal stimulation, and evoked electromyography gave us sufficient information to group these patients according to prognosis--either unfavorable or favorable--for spontaneous return of facial function. When the test results were 26% or more of normal, 100% of the patients had complete recovery without treatment; when the test results were 25% or less of normal, 69% had incomplete recovery: 19% had fair and 50% had poor recovery. Of the 31% with complete recovery, 4 were operated upon. The natural history of herpes zoster oticus in patients with a poor prognosis was improved if a transmastoid extralabyrinthine subtemporal decompression of the labyrinthine segment of the facial nerve was performed within 10 days of onset of the paralysis. The decision to perform this surgery was based upon the results of the prognostic tests mentioned above.
在1974年8月至1980年6月的六年期间，我们对28例耳带状疱疹患者进行了前瞻性研究。我们发现，通过测量泪液分泌、下颌下唾液流量、最大刺激反应以及诱发肌电图所得到的结果，足以让我们根据面部功能自发恢复的预后情况（不良或良好）对这些患者进行分组。当测试结果为正常的26%或更高时，100%的患者未经治疗即完全康复；当测试结果为正常的25%或更低时，69%的患者恢复不完全：19%恢复尚可，50%恢复较差。在完全康复的31%的患者中，有4例接受了手术。如果在面瘫发作后10天内对面神经迷路段进行经乳突迷路外颞下减压术，预后不良的耳带状疱疹患者的自然病程会得到改善。是否进行该手术的决定基于上述预后测试的结果。
