目的探讨翼点入路显微外科手术切除鞍结节脑膜瘤的手术技巧和术中注意事项。方法回顾性分析自2001年4月至200年10月我院采用翼点入路显微手术切除43例鞍结节脑膜瘤的临床资料,并对手术技巧加以总结。结果SimpsonⅠ级切除5例,Ⅱ级切除31例,Ⅲ级切除7例。术后视力改善者24例,视力无变化者6例,视力恶化者2例;术后视野缺损恢复者21例;出现一过性尿崩者6例;出现高热、电解质紊乱者2例:死亡1例。结论应用翼点入路显微手术切除鞍结节脑膜瘤,疗效满意。熟悉鞍区的局部解剖和术中对肿瘤周围重要结构的保护是手术成功的关键。
Objective To explore the surgical technique and intraoperative caudal techniques of microsurgical removal of saddle nodular meningiomas by pterional approach. Methods The clinical data of 43 cases of saddle nodular meningiomas were retrospectively analyzed from April 2001 to October 200 in our hospital with microsurgical pterional approach. The surgical techniques were summarized. Results Simpson Ⅰ grade resection in 5 cases, Ⅱ grade excision in 31 cases, Ⅲ grade resection in 7 cases. 24 cases of postoperative visual acuity improvement, 6 cases of no change in visual acuity, 2 cases of visual acuity deterioration; 21 cases of postoperative visual field defect recovery; 6 cases of transient atrophy; 6 cases of high fever and electrolyte imbalance: 2 cases of death 1 case. Conclusion The application of pterional approach microsurgical removal of saddle nodular meningioma with satisfactory results. Familiar with the anatomy of the saddle area and intraoperative protection of important structures around the tumor is the key to successful operation.
