微血管减压术治疗面肌痉挛的远期效果

目的：探讨微血管减压术治疗面肌痉挛1年以上的远期疗效。方法：对1987年7月至1999年6月间329例患者的临床资料及随访结果进行回顾性分析。结果：本组患者随访1－3年97例，痉挛完全缓解92．7％，明显缓解3．1％，部分缓解2．1％，无改变2．1％；3－5年77例，完全缓解92．2％，明显缓解3．9％，部分缓解1．3％，无改变占2．6％；5－10年121例，完全缓解90．9％，明显缓解4．1％，部分缓解2．5％，无改变2．5％；10年以上34例，痉挛综合缓解91．2％，明显缓解5．9％，无改变2．95。329例中主观满意度≥80％者占82．1％，痉挛复发率5．2％，并发症发生率5．5％，。结论：采用微血管减压术治疗面肌痉挛，尽量减少对脑神经及血管损伤，不遗漏面神经根附近的责任血管，是提高远期疗效养活并发症的重要环节。

Long-term result of microvascular decompression in the treatment of hemifacial spasm

Objective　To study the long-term result (over 1 year) of microvascular decompression in the treatment of hemifacial spasm.　Methods　Three hundred and twenty-nine patients with hemifacial pasm were treated with microvascular decompression from July 1986 to June 1999.　Results　In 97 patients followed up for 1-3 years, the cure rate of spasm was 92.7％, the mprovement 3.1%, and no improvenent rate 2.1%. In 77 patients followed up for 3-5 years，the cure rate of spasm was 92.2％ and 34 patients followed up for over 10 years，the cure rate of spasm were 91.2%. The recurrence rate of spasm was 5.2％. The occurrence rate of postoperative complications was 5.5％.　Conclusion　To improve the long efficacy of microvascular decompression hemifacial spasm, it is necessary to avoid injury to the carnial nerves and blood vessel and leaving out responsible blood vessels near hemifacial nerue.
