目的:进一步提高表皮样囊肿继发三叉神经痛的手术疗效。方法:对我院2009年1月至2013年12月显微手术治疗的22例桥小脑角区表皮样囊肿继发三叉神经痛患者的临床特点、手术方式、临床疗效进行回顾分析。结果:肿瘤切除后,继续探查三叉神经根与血管的关系,解除责任血管压迫,再行感觉根的定位毁损。对15例(68.2%)患者完成了肿瘤全切,7例次全切,术后疼痛症状消失,随访无复发。结论:三叉神经根减压微电凝定位毁损术适用于继发三叉神经痛患者,临床疗效满意,应用前景广泛。
Objective: To further improve the surgical treatment of epidermoid cyst secondary to trigeminal neuralgia. Methods: A retrospective analysis was performed on the clinical features, surgical modalities and clinical effects of 22 patients with cerebellopontine epidermoid cyst secondary to trigeminal neuralgia undergoing microsurgical treatment in our hospital from January 2009 to December 2013. Results: After tumor resection, continue to explore the relationship between the trigeminal nerve root and blood vessels, relieve the responsibility of vascular compression, and then feel the root positioning damaged. Totally 15 patients (68.2%) completed complete tumor resection and 7 subtotal resections. Postoperative pain symptoms disappeared and no recurrence was observed. Conclusion: The trigeminal nerve root decompression and micro-coagulation localization lesion is suitable for patients with trigeminal neuralgia. The clinical effect is satisfactory and the application prospect is wide.
