应用听觉诱发电位检查诊断耳蜗后肿瘤性病变的假阴性率不超过2％,而假阳性率为16～40％;作者报道1984～1988年间听诱发电位检查阳性而神经放射学检查无耳蜗后肿瘤者55例,占同期诊治的耳蜗后病变的25％,55例平均年龄47岁,男38例(70％),女17例(30％)。主要的临床症状为耳聋(49/55,89％),其中单侧进行性或非进行性聋各21例(38％),突聋7例(13％)。其他症状为眩晕、耳鸣、面瘫及半面痉挛共6例(11％)。38例(70％)
Application of auditory evoked potentials in the diagnosis of cochlear neoplasia lesions false-negative rate of not more than 2%, while the false-positive rate of 16 to 40%; the authors reported from 1984 to 1988, positive auditory evoked potentials and neuroradiology without cochlear neoplasms The 55 cases accounted for 25% of the cochlear lesions in the same period. The average age of 55 cases was 47 years. There were 38 males (70%) and 17 females (30%).
