经翼点硬膜外入路切除前床突脑膜瘤

Resection of anterior clinoidal meningiomas via a pterional extradural approach

目的 探讨经翼点硬脑膜外入路在前床突区脑膜瘤切除术中的应用. 方法 南京医科大学附属脑科医院神经外科自2007年6月至2010年5月采用经翼点硬脑膜外入路手术切除前床突脑膜瘤17例,回顾性分析患者的临床资料和疗效. 结果 本组肿瘤全切除12例,次全切除4例,大部切除1例.15例视力障碍患者中11例视力、视野改善,3例无明显变化,1例视力下降.本组无死亡病例. 结论 经翼点硬脑膜外入路手术切除前床突脑膜瘤,有利于肿瘤基底部的血供阻断和前床突下肿瘤与颈内动脉的分离.

Objective To investigate the application of pterional extradural approach in surgery of anterior clinoidal meningioma resection. Methods The clinical data and treatment efficacy of 17 patients with clinoidal meningiomas, admitted to our hospital and performed surgery via a pterional extradural approach from June 2007 to May 2010, were retrospectively analyzed. Results Of the 17 patients with clinoidal meningiomas, 12 received total removal of the tumors, 4 subtotal removal and 1 partial removal. Of the 15 patients with pre-operative visual failure, 11 were markedly improved in visual acuity and visual field, 3 with no obvious changes and 1 with hypopsia. No death was noted.Conclusion The pterional extradural approach in anterior clinoidal meningioma resection can help to block the blood supply to the tumor base and detach the infra-clinoidal tumor from the internal carotid artery.
