微血管减压术治疗桥小脑角区颅神经压迫综合征的疗效分析

目的 探讨微血管减压术（MVD）治疗桥小脑角区颅神经压迫综合征的疗效。方法 回顾性分析我院2012年1月至2014年2月采用MVD治疗的232例颅神经压迫综合征患者的临床资料，其中三叉神经痛93例，面肌痉挛132例，舌咽神经痛7例。结果 术后症状完全消失197例（三叉神经痛81例，面肌痉挛109例，舌咽神经痛7例），明显减轻23例（三叉神经痛8例，面肌痉挛15例），无明显缓解12例（三叉神经痛4例，面肌痉挛8例）。结论 MVD治疗颅神经压迫综合征安全有效，充分的影像学检查、良好的术野暴露、准确的责任血管判断、适当的减压材料放置和细致的显微手术操作可以明显提高手术安全及疗效。

Microvascular decompression surgery for cranial nerve compression syndrome (report of 232 cases)

Objective To explore the curative effect of microvascular decompression (MVD) on cranial nerve compression syndrome (CNCS) and its ineffective causes. Methods The clinical data of 232 patients with CNCS, who underwent MVD from January, 2012 to February, 2014, were analyzed retrospectively. Of 232 patients with CNCS, 93 suffered from trigeminal neuralgia, 132 from facial spasm and 7 from glossopharyngeal neuralgia. Results The postoperative symptoms disappeared completely in 197 patients including 81 with trigeminal neuralgia, 109 with facial spasm and 7 glossopharyngeal neuralgia, were significantly relieved in 23 patients including 8 with trigeminal neuralgia and 15 with facial spasm and were unchanged significantly in 12 patients including 4 with trigeminal neuralgia and 8 with facial spasms. Conclusions MVD is a safe and effective method to treat CNCS. The safety of MVD and its curative effect on CNCS may be significantly enhanced by the preoperative adequate imaging examination, good exposure of the operative field, accurate judgment of the responsible vessel for CNCS, right placement of the relief materials and meticulous microsurgical technique.
