目的探讨在脑干听觉诱发电位、肌电图的监护下进行听神经瘤显微切除的技术。
Objective to explore the skill for microsurgical removal for acoustic neuromas using brainstem auditory evoked potential and electromyography.
诱发肌电图测定近尾部神经的SNCV、波幅及潜伏期，分光光度法测定血浆NO水平。
SNCV, amplitude and latent period in caudal nerve were determined by evoked electromyogram and plasma NO level was measured by spectrophotography.
结果通过术中监测自发肌电图结合电刺激诱发肌电图可以精确判断面神经的位置；
Results The position of facial nerve was correctly located via intraoperative monitoring spontaneous EMG combined with stimulated EMG.
