摘　　要：目的总结电生理监测对听神经瘤术中保留面神经的效果。方法听神经瘤患者161例,采用经枕下乙状窦后入路,显微镜下实施听神经瘤切除术。术中采用神经电生理技术监测面神经诱发电位;术中和术后评估面神经功能。结果术后面神经功能评估结果与术中神经电生理监测结果一致率为62.7%(101/161)。结论神经电生理监测技术应用于听神经瘤显微外科手术可提高面神经解剖和神经功能保留效果;但同时应排除干扰因素,提高电生理监测的准确性。Objective To summarize the outcomes of facial nerve reservation during acoustic neuroma surgery under neural electrophysiological monitoring .Methods Acoustic neuroma resection under microscope was performed via suboccipital retrosigmoid approach in 161 patients .Intraoperative continuous monitoring of evoked potential of the facial nerve was carried out during operation .The facial nerve function was valuated during and after surgery .Results The results of facial nerve function after surgery in 101 cases were consistent with those monitored during operation with an accordance rate of 62.7% .Conclusion The anatomy and facial nerve reservation during acoustic neuroma resection can be improved by intraoperative continuous monitoring of evoked potential of the facial nerve .Some interference factors need to be eliminated in order to improve the accuracy of intraoperative neurophysiological monitoring .
