本文介绍了耳科学家在耳神经学诊断上可能出现失误的一些病例。例一为38岁女性,左耳感音神经性耳聋,CT显示左侧内听道轻度扩大,ABR检查正常,MRI显示左侧内听道有一小的肿瘤,CO_2对照增强CT扫描证实肿瘤确实在内听道内,经颅中凹行左侧内听道手术,发现前庭上神经处有一约8×4mm的肿瘤。术后面神经功能正常,听力无明显改变,ABR反应仍正常。例二为69岁女性,反复发作性眩晕,伴恶心,呕吐、左耳波动性听力损失及轰鸣样耳鸣,左耳听力及言语识别率差,ABR正
This article describes some cases of otologists who may have errors in the diagnosis of otological neurology. One case was a 38-year-old female with left ear sensorineural deafness. CT showed slight enlargement of the left internal auditory canal and normal ABR. The MRI showed a small tumor in the left internal auditory canal. The CO 2 control enhanced CT scan confirmed the tumor indeed Within the auditory canal, transcranial hollow left within the auditory canal surgery and found that the vestibular nerve at a tumor of about 8 × 4mm. The function of the facial nerve was normal, no obvious change in hearing, and the ABR response was still normal. Case 2 was a 69-year-old woman with recurrent dizziness, nausea and vomiting, left ear fluctuating hearing loss and roar-like tinnitus, poor left ear hearing and speech recognition rate, ABR positive
