目的总结经翼点入路显微手术切除巨大鞍结节脑膜瘤的经验。方法2000年2月～2004年11月我院应用显微外科技术,治疗巨大鞍结节脑膜瘤18例。偏侧生长的肿瘤选择翼点入路,先处理肿瘤基底减少血供,再充分利用鞍区脑池及肿瘤与周围结构之间的蛛网膜界面,在保护好重要结构的前提下最大限度地切除肿瘤。结果全切除16例(88.9%),次全切除2例(11.1%),无一例手术死亡。14例随访3个月～4年,平均2.5年,肿瘤无复发。结论翼点入路可对中颅窝、鞍区病变进行良好暴露,提高巨大型鞍结节脑膜瘤全切除率。
Objective To summarize the experience of microsurgical removal of giant saddle nodular meningioma via pterional approach. Methods From February 2000 to November 2004, 18 patients with giant saddle nodular meningioma were treated with microsurgical techniques in our hospital. Select the pterional growth point of the tumor approach, the first treatment of the tumor substrate to reduce blood supply, and then make full use of the sellar cistern and tumor and the surrounding structure of the arachnoid interface, to protect the important structure under the premise of the maximum excision Tumor. Results Total resection in 16 cases (88.9%), subtotal resection in 2 cases (11.1%), no case of surgical death. 14 cases were followed up for 3 months to 4 years, an average of 2.5 years, no recurrence of the tumor. Conclusion The pterional approach can well expose the lesion in the middle cranial fossa and the saddle area, and improve the total resection rate of the giant saddle nodular meningioma.
