目的对48例颅底脑膜瘤手术治疗结果进行回顾性分析。方法根据肿瘤主体所在部位不同而采取不同的手术入路,显微操作切除肿瘤。适当病例术前进行栓塞,残余肿瘤采取伽马刀治疗。结果病变切除达到Simp-sonl、2级病例所占百分比为:鞍结节及鞍旁脑膜瘤79%(11/14),前床突及蝶骨嵴内侧脑膜瘤62%(16/26),岩斜区及蝶岩斜区脑膜瘤63%(5/8),病死率为4%。结论根据肿瘤大小与部位选择合理的手术入路和显微外科操作有助于提高疗效,减少并发症。
Objective To retrospectively analyze the surgical treatment results of 48 cases of skull base meningioma. Methods According to the different parts of the tumor, different surgical approaches were taken and the tumors were excised microsurgically. Appropriate cases preoperative embolization, residual tumor to take gamma knife treatment. Results The lesions were resected to Simp-sonl. The percentage of grade 2 cases was 79% (11/14) in saddle nodules and parasellar meningioma, 62% (16/26) in anterior prominence and sphenoid ridge medial meningiomas, 63% (5/8) meningiomas in petroclival and butterflies incline, and the case fatality rate was 4%. Conclusion According to tumor size and site selection reasonable surgical approach and microsurgery helps to improve the curative effect and reduce the complications.
