【摘要】 目的探讨岩骨前部切除入路在岩斜坡区脑膜瘤手术中的应用。方法通过对收治的46例岩斜坡区脑膜瘤患者采用联合岩骨前部切除入路的显微外科治疗方法进行分析,总结患者的影像学资料、临床表现、手术方案及手术疗效。结果该组患者肿瘤全切33例,次全切9例,大部分切除4例,术后原有症状和体征完全消失17例,症状较术前减轻10例,脑神经损害症状同术前6例;原有神经功能障碍加重或出现新神经功能障碍21例。结论岩骨前部切除可以获得对岩斜区良好的暴露,根据肿瘤累及范围选择不同的手术入路是手术成功的关键。更多还原

【Abstract】 Objective To discuss the role of anterior petrosectomy played in surgical treatment of petroclival meningioma. Methods Clinical data of 46 patients with petroclival meningioma receivingt microsurgery through skull base approach combined with anterior petrosectomy in our department from June 2009 to Oct 2013 were analyzed retrospectively.The data analyzed included data of imaging,clinical manifestations,surgical program,and therapeutic effect. Results Of all the 46 patients,total tumor removal was in 33,subtotal in 9,and partial in 4.
