目的 :提高蝶骨嵴脑膜瘤的全切率 ,降低死亡率和致残率。方法 :对 2 6例蝶骨嵴脑膜瘤的手术治疗作回顾性分析。结果 :外侧型 17例均达肿瘤全切 ,无并发症 ;内侧型 9例 ,2 1例全切除 ,术后偏瘫 1例 ,无死亡病例。结论 :宜采用翼点入路显微镜下切除肿瘤。对外侧型者全切除多无困难 ;内侧型者术中宜尽早离断肿瘤的主要血供 ,体积较大显露基底困难者 ,可先行包膜内分块切除 ,而后剥离切除其囊壁。术中应注意保护邻近的视神经、大脑中动脉、颈内动脉及其分支。
Objective: To improve the rate of full sphenoid ridge meningioma, reduce mortality and morbidity. Methods: A retrospective analysis of 26 cases of sphenoid ridge meningioma surgery. Results: The lateral type of 17 cases were all tumor resection, no complications; medial type in 9 cases, 21 cases of total resection, postoperative hemiplegia in 1 case, no deaths. Conclusion: It is appropriate to use pterional approach to remove the tumor under microscope. On the lateral type of total excision without more difficulty; medial type of surgery should be as early as possible to break off the main blood supply of the tumor, the larger volume revealed the basal ganglia, the capsule may be removed within the block, and then stripped to remove the wall. Surgery should pay attention to the protection of the adjacent optic nerve, middle cerebral artery, internal carotid artery and its branches.
