不同责任血管处理方式对面肌痉挛微血管减压术疗效的影响

目的探讨面肌痉挛微血管减压术中不同类型的责任血管减压方法及疗效的关系。方法回顾研究我院手术治疗的面肌痉挛患者272例，对责任血管进行分类，并采取不同的减压方法，观察术后疗效。结果典型小脑前下动脉压迫141例，术后治愈率为98．58％；椎动脉和小脑前下动脉联合压迫82例，术后治愈率为95．12％；伴有旁穿支压迫28例，术后治愈率为92．86％；位于面听神经根部之间的压迫21例，术后治愈率为90．48％；总治愈率为96．32％。结论在面肌痉挛微血管减压术中，对不同责任血管采取不同的减压方式可显著提高治愈率。

Therapeutic effect and decompression way of distinct offending vessel in hemifacial spasm microvascular decompression

objective To study the therapeutic effect and decompression way of distinct offending vessel in hemifacial spasm microvascular decompression operation. Methods 272 patients with hemifacial spasm were operated in our department, different ways based on offending vessel were adopted, and observed the therapeutic effect. Results The cure rate of typical anterior inferior cerebellar artery compression（ n = 141 ） is 98.58%, the cure rate of arteria vertebralis and anterior inferior cerebellar artery compression （ n = 82 ） is 92.86%, the cure rate of offset blood vessel compression（n = 28） is 92. 86%, and the cure rate of blood vessel compression which lies in intermedial of VII and vm cranial nerve （n = 21 ） is 90.48 % , total cure rate is96.32% , this surpasses reports of documents. Conclusion Different decompression way of distinct offending vessel in hemifacial spasm microvascular decompression operation can raise cure rate significantly.
