神经内镜下经眶上锁孔入路切除大、中型鞍结节脑膜瘤

目的 探讨神经内镜下经眶上锁孔入路切除大、中型鞍结节脑膜瘤(TSM)的疗效.方法 总结与分析所收治的7例14只眼以视力障碍为主要表现的TSM患者,肿瘤直径2.8～4.7 cm,经眉弓切口,形成3.5cm×2.0 cm眶上骨窗,在神经内镜下切除肿瘤.结果 7例肿瘤均全切(simpson Ⅰ级2例,simpsonⅡ级5例).术后视力恢复情况:9只眼视力好转,3只眼视力维持,2只眼视力恶化.随访6～13个月未见肿瘤复发.结论 神经内镜下经眶上锁孔入路易于处理肿瘤周围的神经血管结构,便于保护视神经与周围血管,是切除大、中型TSM的有效方法.

Neuroendoscopic surgery of supraorbital keyhole approach for the removal of medium and large sized tuberculum sellae meningiomas

Objective To explore the effect of neuroendoscopic surgery for the removal of medium and large sized tuberculum sellae meningiomas through supraorbital keyhole approach.Methods A retrospective research was performed on 7 case of patients with tuberculum sellae meningioma who underwent endoscopic surgery through supraorbital keyhole approach.The main performance of patients as tumor diameter were 2.8-4.7 cm and the skin incision located at superciliary aich which size of intra-frontal bone window was 3.5 cm× 2.0 cm.Results Total removal was achieved in 7 cases(simpson Ⅰ grade in 2 patients,sirnpson 1Ⅱ grade in 5 patients).Postoperative,the visual outcomes of eyes were showed improvement in 9 eyes,remained steady in 3 eyes,and deterioration in 2 eyes.All patients were followed up for 6-13 months and no recurrence was found.Conclusion Neuroendoscopic surgery through supraorbital keyhole approach is an effective method for the resection of medium and large sized tuberculum sellae meningiomas.
