微血管减压术治疗三叉神经痛74例疗效分析

Microvascular decompression for trigeminai neuralgia： a clinical efficacy analysis of 74 cases

目的 探讨微血管减压术治疗三叉神经痛（TN）的临床疗效和并发症。方法 武警江苏总队南京医院口腔科自2002年8月至2009年4月共行微血管减压术治疗TN患者74例．回顾性分析患者的临床资料和疗效。结果 本组患者术后均临床治愈出院，无死亡病例。术后颅内血肿l例（1．35％），术侧小脑水肿致非交通性脑积水l例（1．35％），颅内感染2例（2．7％），均经积极对症治疗后缓解。全部患者随访3个月～6年，无复发病例，遗留术侧轻微面瘫2例（2．7％），听力轻度下降1例（1．4％）。结论 微血管减压术解除了TN的常见病因，保留三叉神经的功能，是治疗TN的首选方法。

Objective To investigate the clinical effect of microvascular decompression on patients with trigeminal neuralgia （TN） and its complications. Methods A retrospective analysis of 74 patients with microvascular decompression, admitted to our hospital from August 2002 to April 2009, was performed; the clinical data and the treatment efficacy were analyzed. Results The total effective rate was 100% without death. Intracranial hematoma appeared in 1 patient （1.35%）; edema of the cerebellum in the operated side caused 1 patient （1.35%） having non-communicating hydrocephalus and 2 （2.7%） having intracranial infection, and all were relieved symptoms after treatment. All patients were followed up for 3 months to 6 years; no recurrence was noted; facial paralysis in 2 （2.7%） and slight hearing-loss in lwere found. Conclusion Microvascular decompression, lifting the common cause of TN and fully retaining the function of trigeminal nerve, is the preferred method for treatment of TN.
