微血管减压术治疗面肌痉挛的临床研究

目的探讨微血管减压术治疗面肌痉挛的临床疗效。方法回顾性分析2004年来79例面肌痉挛患者,行微血管减压术治疗,分析发病原因、术后疗效和并发症。结果面肌痉挛发病原因主要是由于血管压迫面神经出脑干区,产生的机械性搏动刺激所致。术中发现责任血管与小脑前下动脉(AICA)相关占68.4%(54例),复合血管压迫者占36.7%(29例),微血管减压术后总有效率为100%。术后并发症常见的有头痛、耳鸣,较严重的有患侧面肌瘫痪、听力下降,多可在6个月后逐渐恢复。结论微血管减压术治疗面肌痉挛的有效率高,并发症少,复发率低,有很好的治疗效果。

Objective To investigate the curative effect of facial spasm treated with microvascular decompression（MVD）. Methods Seventy nine patients of facial spasm who had underwent the MVD operation were analyzed retrospectively from etiopathogenisis, postoperative outcome and complication since 2004. Results The etiopathogenisis of facial spasm mainly was the root exit zone of facial nerve compressed by vessels. During operation the offending vessel was the anterior inferior cerebellar artery accounted for 68.4% （54/79） and multiplicity vessel accounted for 36. 7 % （29/79）. The total effective rate was 100%. The most of postoperative complications were the headache and the bombus. Some other patients had facial palsy and auditory acuity decreased, but they were cured in six months. Conclusions The microvascular decompression has high total effective rate, low rate of complication, low recurrence rate and the excellent effect.
