摘　　要：目的报道11例起源于Meckel腔脑膜瘤的临床表现和分型，探讨经显微手术切除Meckel腔脑膜瘤的手术入路选择和显微手术治疗策略，以提高肿瘤的手术全切除率与改善术后疗效。方法回顾性分析2004年6月至2012年5月经显微手术切除的11例Meckel腔脑膜瘤的临床资料。肿瘤分为三型，根据肿瘤的类型选择手术入路。肿瘤最大直径在1．5～2．7cm（平均2．2cm）。结果肿瘤根治性全切除（simpsonⅠ）9例，SimpsonⅡ全切除2例。术后无新增颅神经损害，无手术相关的死亡病例及其它严重并发症。结论乙状窦后-经内听道上入路适用于Ⅱ型和ⅢMeckel腔脑膜瘤。Mekel腔脑膜瘤可做到根治性切除，防止肿瘤的复发。Objective To investigate the clinical features and types of 11 cases of Meckel＇s cave （MC） meningianms and to explore the surgical approach and management strategies in order to improve the total resection rate and the outcomes of MC meningioma.Methods The consecutive 11 cases of MC rneningiomas treated between January 2004 and May 2012 by microsurgical techniques were reviewed retrospectively. The maximum diameter of the tumors ranged from 1.5 cm to 2.7 cm （mean, 2.2 cm）. These cases were classified into three different types according to the tumor extension： Type I, tumors mainly confined to MC; Type II, MC meningioroas with extension into the middle fessa; Type m, MC meningiomas with extension into the posterior fossa. Results Among all patieras, radical total turoor resection （Sinvson I） was achieved in 9 patients and gross total removal （Simpson II ） in 2 cases. No surgery-asseciated mortality and no new-occurred cranial nerve deficits. Conclusion Retresigmoid trans-supratwatal approach is suitable for removal of MC meningiomas （type II and III）. MC ineningiomas can be totally removed to prevent the recurrence.
