利用F波评价舌下-面神经吻合术治疗面瘫的疗效

Preliminary study of facial nerve F wave evaluation hypoglossal-facial nerve reconstruction with predegenerated nerve graft for peripheral facial palsy

目的 初步探讨利用面神经F波检测技术评价预变性自体神经桥接舌下-面神经吻合术对面瘫的疗效.方法 回顾性分析2011年11月至2014年2月北京天坛医院进行桥脑小脑角区神经鞘瘤术后并行预变性自体神经桥接舌下-面神经吻合术患者30例,术前术后分别行面神经功能评估及F波、M波检测并随访.结果 随访时间3～ 20个月,平均8个月;手术后面部肌群运动功能分级提高12例;患侧F波潜伏期显著改善16例,差异有统计学意义（P＜0.05）.结论 采用预变性自体腓肠神经桥接舌下神经-面神经吻合术是治疗周围性面瘫的一种有效方法,面神经F波检测可作为评价手术效果的客观指标之一.

Objective To Preliminary study of facial nerve F wave evaluation hypoglossal-facial nerve reconstruction with pre-degenerated nerve graft for peripheral facial palsy.Methods The clinical data were retrospectively reviewed for 30 patients with peripheral facial palsy after cerebellontine angle underwent nerve anastomosis were analyzed between November 2011 and February 2014.F wave and M wave detection were used to evaluate the pre-,post-opertive and status.The hypoglossal-facial nerve by ＂side-to-side＂ anastomisis was performed.Results All patients were followed-up.The mean time of follow-up was 8 months（ranged from 3 to 20 months）.12 patients were found a higher recovery of facial nerve function after the nerve anastomosis.16 patients who F wave of post-opertive were found a higher recovery compared to F wave of pre-opertive （P 〈 0.05）.Conclusion The hypoglossal-facial nerve by ＂side＂-to-side anastomisis with pre-degenerated auto-nerve graft was effective for the treatment of peripheral facial palsy after CPA tumor resection,F wave can be used as one of the objective index for the effect of the operation.
