自1976年起作者们对疑似多发性硬化、听觉阈值评定、婴儿猝死综合征、儿童脑干神经胶质瘤、全身神经性或代谢性疾病和蜗后疾患(听神经瘤)等患者676例作了脑干听觉诱发电位检查,尤其在诊察有无听神经瘤时,此项检查应用价值较高。脑干听觉诱发电位正常,基本上可排除听神经瘤的诊断。对听神经瘤,藉脊髓造影剂(Pantopaque)作颅后窝脊髓造影术而报告正常的患者,其中34％(13/38)脑干听觉诱发电位却不正常,此点与以往文献介绍有所不同,这属偏高的假阳性率,因此脑干听觉诱发电位并不是诊断听神经瘤的唯一特异方法。
Since 1976, 676 patients with suspected multiple sclerosis, auditory threshold assessment, sudden infant death syndrome, pediatric brain stem glioma, generalized neurological or metabolic diseases and retrocochlear disorders (acoustic neuroma) Brainstem auditory evoked potentials, especially in the diagnosis of acoustic neuroma, the examination of high value. Brainstem auditory evoked potential is normal, can basically rule out the diagnosis of acoustic neuroma. 34% (13/38) of the brainstem auditory evoked potentials were abnormal in patients with acoustic neuroma who reported normal posterior pit radiography with the Pantopaque, which is different from previous literature , Which is a high false positive rate, so brainstem auditory evoked potential is not the only specific method of diagnosis of acoustic neuroma.
