摘要
目的探讨枕骨大孔腹侧脑膜瘤的显微外科技巧，以期提高手术疗效。方法2004年7月～2014年7月手术治疗35例枕骨大孔腹侧脑膜瘤患者，其中31例行基础远外侧入路，4例行扩大远外侧部分枕髁磨除入路。总结该部位脑膜瘤的病理解剖特点、临床特征、手术技巧及术后注意事项。结果肿瘤全切32例，近全切3例。术后短暂性脑神经功能障碍15例，永久性脑神经功能障碍2例。肢体运动障碍6例。5例患者术后暂时行气管切开。无1例死亡。结论后组脑神经、椎动脉及脑干是该区域肿瘤术中保护重点；远外侧入路是该区域肿瘤首选，适当的枕髁磨除有利于肿瘤的充分暴露。
Objective To investigate the microsurgical technique of ventral foramen magnum meningiomas for improving therapeutic efficacy. Methods Clinical data of 35 patients suffering from foramen magnum meningiomas surgically treated from July 2004 to July 2014 in our department were analyzed retrospectively. The operation was performed via classic far lateral approach and far lateral transcondylar approach in 31 and 4 cases respectively. Their pathologic features, clinical characteristics, surgical technique and postoperative cautions were summarized. Results Complete tumor resection was achieved in 32 cases and subtotal resection in 3. Transient cranial nerve dysfunction occurred in 15 patients and permanent dysfunction in 2. 6 patients had limb movement disorders. Tracheotomy was performed in 5 patients. No deaths occurred. Conclusions Posterior cranial nerve, vertebral artery and brainstem are key protected aims during surgical treatment of foramen magnum meningiomas. The far lateral approach is preferred, and proper removal of occipital condyle will benefit tumor exposion.
