目的 研究面神经监测在听神经瘤手术中保护面神经的方法和意义。方法 将62例患者随机分为监测组与对照组,然后比较分析两组患者术前、术后10天及随访后的面神经功能状况。结果 术后10天面神经功能Ⅰ～Ⅲ级者,两组分别为26例和15例,Ⅳ～Ⅴ级者分别为6例和15例;随访后两组面神经功能Ⅰ～Ⅲ级者分别为29例和20例,Ⅳ～Ⅴ级者分别为3例和10例;统计学分析差异有显著性。结论 面神经监测能显著提高听神经瘤术中面神经的解剖和功能保存率及患者术后的生存质量。 Objective To study the method and significance of facial nerve monitoring for facial nerve in acoustic neuroma surgery. Methods Sixty-two patients were randomly divided into the monitoring group and the control group. The facial nerve function of the two groups were compared before and 10 days after operation and after follow-up. Results 10 days after operation, facial nerve function grade Ⅰ ~ Ⅲ, two groups were 26 cases and 15 cases, Ⅳ ~ Ⅴ grade were 6 cases and 15 cases; follow-up after facial nerve function Ⅰ ~ Ⅲ grade were 29 Cases and 20 cases, Ⅳ ~ Ⅴ grade were 3 cases and 10 cases; statistical analysis showed significant differences. Conclusion Facial nerve monitoring can significantly improve the anatomic and functional preservation rate of facial nerve in acoustic neuroma and the postoperative quality of life of patients.
