岩斜区脑膜瘤的显微外科治疗(附15例报告)

Microsurgical treatment of petroclival meningiomas:15 cases report

目的:探讨岩斜区脑膜瘤的显微手术治疗效果。方法:对15例行显微手术治疗的岩斜区脑膜瘤患者的临床资料及手术效果进行分析总结。结果:15例患者中,10例(66.7%)达到肿瘤全切(Simpson I,II级),3例(20%)达到次全切(Simpson III级),2例(13.3%)达到大部分切除,无手术死亡病例。肿瘤未全切的5例患者中,4例术后行伽玛刀治疗。13例患者术后被随访,时间为6个月-6.5年,均未见肿瘤复发或再生长。失访2例。结论:显微外科手术是治疗岩斜区脑膜瘤安全、有效的方法。

Objectlve：To investigate the microsurgical outcomes of petroclival meningiomas. Methods： A retro- spective analysis of the clinical data and prognosis of microsurgery was conducted in 15 cases with petroclival menin- giomas. Their clinical manifestations and surgical outcomes were analyzed to evaluate the significance of microsurgical management. Results：Of the 15 patients, total resection （Simpson grade I） and sub- total resection （Simpson grade II） of the tumor was achieved in 10 and 3 cases （66.7% and 20% ） , respectively. The remaining 2 patients （13.3%） achieved greater partial tumor resection. No death occurred postoperatively. After operation,4 of the 5 pa- tients,whose tumor was not totally resected, undertook gamma knife radiotherapy. 13 patients were followed up for 6 months to 6.5 years. No patient suffered tumor recurrence or regrowth. 2 patients got lost during the follow up period. Conclusion：Microsurgical treatment is a safe and effective therapy for petroclival meningiomas.
