目的探讨影响微血管减压术治疗面肌痉挛远期疗效的因素及提高疗效的方法。方法分析253例随访13～144个月(平均73个月)的资料。结果痉挛消失232例(91.7%)，痉挛部分缓解10例(4%)，痉挛复发11例(4.3%)。痉挛复发者再手术时发现遗漏压迫血管、减压材料移动是造成手术失败及复发的原因。结论采用微血管减压术治疗面肌痉挛，不遗漏面神经根附近的责任血管，是提高远期疗效的重要环节。

Objective 　To investigate the factors associated with long-term efficacy of microvascular decompression for hemifacial spasm. Methods　253 cases of hemifacial spasm treated with microvascular decompression were followed 13 to 144 months (mean 73 months). Results　Hemifacial spasms were obliterated in 232 cases (91.7%) and were partially relieved in 10 cases (4%). However, hemifacial spasm recurred 11 cases (4.3%). We re-operated on those who had recurrent hemifacial spasm and found that the material used for previous decompression had moved. The movement of decompression material could be the cause of spasm recurrence. Conclusions　Upholding of depression material around the blood vessels against movement near the facial nerve plays an important role for improving the long-term efficacy of MVD for hemifacial spasm.
