作者统计普通耳鼻喉科门诊病人115例,年龄16～80岁,平均53岁。93例(81％)诉一侧听力障碍,常伴耳鸣或眩晕;18例(16％)双耳难听,骨导听阈两侧不对称;4例(3％)耳鸣或眩晕,两侧听阈不对称。11例(10％)受检耳纯音听阈大于90dBHL。115例均需排除桥脑小脑角肿瘤,其中4例确诊为听神经瘤,经手术证实。全部病例均行ABR、听反射、ABLB、冷热试验和CT检查。结果:听神经瘤病例,ABR均异常(双耳闻Ⅰ～Ⅴ波间潜伏期大于0.2秒,双耳间Ⅴ波潜伏期差大于0.3秒或Ⅴ波缺如),无听神经瘤病例66％ABR正 The authors statistics 115 cases of general ENT outpatients, aged 16 to 80 years, mean 53 years. Ninety-three patients (81%) complained of hearing impairment, often accompanied by tinnitus or vertigo. Eighteen patients (16%) had unpleasant ears and bilateral bone conduction hearing thresholds were asymmetric. Four patients (3%) had tinnitus or dizziness. symmetry. Eleven patients (10%) received ear pure tone hearing threshold greater than 90dBHL. 115 cases were required to rule out pontine cerebellar angle tumors, of which 4 were diagnosed as acoustic neuroma confirmed by surgery. All patients underwent ABR, auditory reflex, ABLB, hot and cold test and CT examination. Results: Acoustic neuroma cases, ABR were abnormal (both ears heard Ⅰ ~ Ⅴ latency of more than 0.2 seconds between the two ears, Ⅴ wave latency was greater than 0.3 seconds or Ⅴ wave absence), no acoustic neuroma 66% ABR positive
