颞枕经小脑幕入路显微手术切除岩斜区脑膜瘤

目的 探讨颞枕经小脑幕人路切除岩斜区脑膜瘤的可行性.方法 对18例经颞枕入路切除的岩斜区脑膜瘤患者进行回顾性研究.全部病例均在术前行MRI检查.结果 18例于术患者,肿瘤直径<3.0cm4例;3.0-4.5cm5例;>4.5 cm 9例,最大径可达到7.6 cm×7 cm X7 cm.全切8例,次全切9例,大部分切除1例.偏瘫2例,面瘫1例.听力减退1例,无脑脊液耳漏、失语.1例死亡.结论 颞枕经小腩幕入路切除岩斜区脑膜瘤具有可行性,可以使鞍旁海绵窦区、上中斜坡、岩骨背侧小脑脑桥角区暴露充分,利十该区域占位性病变的手术治疗.

Micrmurgery for petroclival meningiomas through tempoccipital transtentorail approach

Objective To discuss the feasibility of microsurgery for petroclival meningiomas through tempoccipital transtentorail approach.Methods The retrospective analysis of eighteen cages of petroclival meningiomas Was performed.All the tumors were resected through tempoccipital transtentorail approach.All patients were scanned by MRI before operations.Results The size, of tumors:four cases<3.0 cm.five cases 3.0-4.5 cm,nine csses>4.5 cm.One patient had the biggest tumor(7.6cm×7cm ×7cm).Total resection was,achieved in eight cases,subtotal resection in nine cases.There were two cases with paralysis,one case with hemifacial palsy,and one cage with heating loss.Cerebrospinal fluid leakage and aphasia were not observed.One patient died after operation.Conclusion Tempoccipital transtentorail approach could be useful for resection of petroclival meningiomas.Surgeon could get a good view involving the ares of cavernous sinus,clivus and cerebellopontine angle.
