目的：探讨听神经鞘瘤术中电生理监测对面神经功能保护和评估的作用，提高肿瘤全切率、面神经解剖和功能保留率。方法：对27例听神经鞘瘤患者行术中电生理监测，研究其变化与术后面神经功能的关系。结果：肿瘤全切除24例（88.9%），次全切除3例（11.1%），面神经解剖保留26例（96.3%），面神经功能保留17例（63.0%），无死亡病例，术末与术前经颅电刺激运动神经（面神经）诱发电位的比值<60%者术后可能面神经功能差。结论：听神经鞘瘤术中电生理监测对于安全切除肿瘤，保护、评价面神经功能有重要价值，该比值<60%是面神经功能可能严重损伤的警示。

Objective:To explore the significance of protecting and evaluating the function of the facial nerve in the operation of acoustic neurilemoma with intraoperative electrophysiologic monitoring and to increase the entirely-resected rate of acoustic neurilemoma and the anatomical and functional preservation rate of the facial nerve.Method: Electrophysiologic monitoring was performed during the operation of 27 cases of acoustic neurilemoma and the relationship between the electrophysiologic change and the postoperative function of the facial nerve were investigated.Result:24 cases(88.9%) were completely resected and 3 cases(11.1%) were subtotally resected. The facial nerve was anatomically preserved in 26 cases(96.3%) and functionally preserved in 17 cases(63.0%) without operative mortality. Less than 60.0% of the postoperative-to-preoperative transcranial electrical motor evoked potentials of the facial nerve was possibly related to the poorly facial function after the operation.Conclusion:Intraoperative electrophysiologic monitoring has an important value for protecting and evaluating the function of the facial nerve. Less than 60.0% of the postoperative-to-preoperative transcranial electrical motor evoked potentials of the facial nerve is an alarm for a possibly severe injury of the facial nerve function.
