微血管减压术治疗面肌痉挛96例分析

目的探讨微血管减压术治疗面肌痉挛的责任血管、手术疗效以及手术策略。方法回顾性分析采用微血管减压术的96例面肌痉挛病人的临床资料。结果本组术中均能见到血管压迫面神经根出脑干处，均为动脉血管压迫。术后68例症状完全缓解，26例明显减轻，2例手术无效；其中有1例复发。结论微血管减压术是面肌痉挛的有效治疗方法，熟练的显微外科技术，术中责任血管的识别以及减压棉片的放置是影响手术疗效的关键。

Analysis of microvascular decompression for hemifacial spasm (a report of 96 cases)

Objective To investigate the responsibility blood vessel, surgical effect and strategy of the microvascular decompression for hemifacial spasm. Methods The clinical data of 96 patients with hemifacial spasm treated by microvascular decompression were analyzed retrospectively. Results The blood vessels that compressed the facial nerve root-exit-brain stem zone were found in the operation. All the vessels were arteries. Of 96 patients, symptoms were completed remission in 34, significantly reduced in 13, invalid in 2 and recurrenced in 1. Conclusions Mierovaseular decompression is the most effective method for hemifacial blood vessel and the deposition spasm. Skilled microsurgical technique, recognition of the responsibility of the cotton are the key to the surgery.
