作者们报告2例先有消退性外周性面瘫,分别于4年和7年后,作出了听神经瘤的诊断。通过此2病例,作者们提出了诊断听神经瘤的新的见解。病例1:36岁女性。1980年3月就诊。主诉左耳突聋,头位变动时有眩晕。追溯4年前曾出现左侧外周性面瘫。当时诊断为贝尔氏麻痹,一月后完全消失。耳鼻喉科及脑神经检查,除耳聋外,均正常。听力计检查:左耳感音性聋,阈上检查无重振。Metz试验,听力无易疲劳性。溯听呈Ⅰ型曲线,无特征性症状。由于4年前曾患左侧面瘴,又有同侧耳聋,因而决定系统地寻查听神经瘤。检查项目和结果:(1)内耳道体层摄片正常;(2)耳蜗电图阈值较听力曲线为佳;延髓潜
The authors reported 2 cases of first exacerbation of peripheral facial paralysis and made acoustic neuroma diagnoses at 4 and 7 years respectively. Through these 2 cases, the authors present new insights into the diagnosis of acoustic neuroma. Female patients 1:36 years old. March 1980 treatment. Chief complaint of left ear sudden deafness, dizziness head changes. Left four weeks ago there have been peripheral facial paralysis. Bell’s paralysis was diagnosed at the time and disappeared completely after January. ENT and cranial nerve examination, except for deafness, are normal. Audiometer examination: left ear sensory deafness, no resurgence of the threshold examination. Metz test, no fatigue and hearing. Tracing was type Ⅰ curve, no characteristic symptoms. Because 4 years ago suffered from the left side of the face, there are ipsilateral deaf, so decided to systematically search for acoustic neuroma. Check items and results: (1) normal intrathoracic radiography; (2) cochlear electrogram threshold better than the hearing curve; medullary potential
