目的探讨经扩大前颅底入路对20例前颅底肿瘤的显微手术。方法回顾性分析20例前颅底肿瘤显微手术的入路和手术切除相关因素。结果20例前颅底肿瘤经扩大前颅底入路,其中经硬膜下入路15例,经硬膜外入路5例,全切除10例,次全切除6例,大部切除4例。结论经扩大前颅底入路容易显露前颅底结构,对脑组织牵拉轻,扩大了手术适应证,降低了肿瘤切除的风险。
Objective To investigate the microsurgical treatment of 20 anterior skull base tumors by an anterior cranial base approach. Methods Retrospective analysis of 20 cases of anterior skull base tumor microsurgery approach and surgical resection related factors. Results 20 cases of anterior skull base tumors were enlarged anterior skull base approach, including 15 cases under subdural approach, 5 cases underwent epidural route, 10 cases underwent total resection, 6 cases underwent total subtotal resection and 4 cases underwent resection . Conclusions The anterior cranial base structure is easily revealed by the enlarged anterior skull base approach, the pulling of the brain tissue is light, and the surgical indications are expanded, reducing the risk of tumor resection.
