显微血管减压术治疗面肌痉挛92例报告

目的 探讨显微血管减压术治疗面肌痉挛的手术疗效及并发症。方法 选取濮阳市安阳地区医院2006年1月-2013年06月采用显微血管减压术治疗HFS病例92例，现在对患者的临床资料进行回顾性分析。结果 全部病例经6个月至7年随访，抽搐完全消失77例，术后明显减轻7例，部分减轻6例，手术无效2例，无复发。并发症主要包括听力障碍5例，面瘫13例，耳鸣4例，声音嘶哑1例，脑脊液漏2例，无死亡和致残病例发生。结论 显微血管减压术是面肌痉挛最有效的治疗方法 ，娴熟的显微外科技术及桥小脑角区局部解剖知识、术中面神经根部的显露、正确识别责任血管、减压棉片的大小及放置的位置等是确保手术疗效及减少并发症的重要因素。

Experience of microvascular decompression for hemifacial spasm 92 cases

Objective To investigate surgical effect and complication of microvascular decompression（MVD） on hemifacial spasm（HFS）. Methods A retrospective analysis was conducted for 92 patients with HFS enrolled in our hospital from Feb. 2006 to Jun. 2011 accepted with MVD. Results After a follow - up of 6 months to 7 years, 77 patients were cured for HFS,7 patients were alleviated,6 patients were partly alleviated 2 patients were invalided and no recurrence, suggesting a total efficiency of 97. 7%. Conclusion MVD operation is the most available treatment to HFS. Skilled microsurgical technique along with the local anatomy knowledge of cerebellopontine angle, good exposure of root exit zoon （ REZ）, correct recongnition of offending vascular, the appropriate size and proper positioning of Teflon grafts are important factors to assure high efficacious and reduce complications in microvascular decompression.
