经翼点入路切除蝶骨嵴脑膜瘤16例分析

Microsurgical treatment of sphenoid ridge meningiomas via pterion approach

目的:总结经翼点入路显微手术切除蝶骨嵴脑膜瘤的经验。方法:对16例蝶骨嵴脑膜瘤的显微外科手术作回顾性分析。手术入路均为翼点入路,其中蝶骨嵴内1/3者6例,中1/3者4例,外1/3者6例。均在显微镜下行肿瘤切除。结果:全切除13例,大部切除2例,部分切除1例;其中1例术前已出现脑疝,术后死亡;术后偏瘫1例;余恢复良好。结论:采用翼点入路,熟练掌握术区显微解剖,保护重要神经和血管,显微镜下切除肿瘤可提高肿瘤切除率,减少术后神经功能障碍。

Objective： To sum up the experience of treating sphenoid ridge meningiomas by microsurgery via pterional approach. Methods： Sixteen eases of sphenoid ridge meningiomas were analyzed retrospectively. The surgery was performed via pterion approach. Six of the cases were of medial type tumor,4 cases middle type tumor and 6 cases lateral type tumor. Results：The tumors were totally resented in 13 cases, subtotally resented in 2 cases and partially in 1 cases. One of them died and 1 had hemiplegia. Conclusions： Pterion approach plus micromanipulation and proper preservation of vital vessel and nerves can improve the removal rate of sphenoid ridge meningioma and reduce postoperative nervous malfunction.
