对经手术证实的２１５例听神经瘤患者中以突聋为首发症状的４９例（２２．８％）进行分析，发现：发生率较以前文献报告高。听神经瘤突聋发生率与年龄、性别、患侧及肿瘤大小无关。听力曲线无显著特征，其中９例有过听力恢复或波动。其与特发性突聋的鉴别，镫骨肌反射及脑干电反应测听有一定意义，但听神经瘤的确诊仍有赖于高分辨力ＣＴ、ＭＲＩ等影像学诊断。内耳道充气ＣＴ扫描对小听神经瘤的确诊很有意义。
Of the 215 patients with acoustic neuroma confirmed by surgery, 49 (22.8%) with sudden deafness as the first symptom were analyzed and found to have a higher incidence than previously reported. Acoustic neuroma sudden deafness incidence and age, gender, ipsilateral and tumor size has nothing to do. Hearing curve showed no significant features, of which 9 cases had hearing recovery or fluctuations. Its identification with idiopathic sudden deafness, stapedius reflex and bradykinesia electrical audiometry have some significance, but the diagnosis of acoustic neuroma still depends on the high resolution CT, MRI and other imaging diagnosis. Internal auditory canal CT scans for the diagnosis of small acoustic neuroma is of great significance.
