目的 探讨经眶上裂沟通眼眶-中颅窝的脑膜瘤手术的颅底重建的方法。方法 总结我院自2007-01至2012-05采用眶-翼点入路显微手术治疗72例通过眶上裂沟通眼眶-中颅窝底的脑膜瘤患者的临床资料,对该类肿瘤颅底重建的方法进行分析。结果 颅底硬脑膜及骨缺损修补效果满意,肿瘤全切率为90.3%。术后无脑脊液漏、局部脑膨出、脑膜炎等并发症的发生;皮下积液12例。 结论 对于该类颅眶沟通性脑膜瘤行眶-翼点入路显微手术是较好的手术方式,颅底重建是手术成功的关键之一。

Objective To investigate the strategy of skull base reconstruction after resection of meningioma communicating the orbit and middle cranial fossa. Methods A retrospective review was carried out of the clinical data of 72 patients who underwent microsurgical operations by orbito-peronal approach for cranio-orbital communicating skull base meningioma in this department between Jan 2007 and May 2012. Then the method of skull base reconstruction after tumor resction was discussed. Result In this series, skull base reconstruction including dural repair and cranioplasty resulted in satisfactory outcome. The complication such as cerebrospinal fluid leakage, meningocele, meningitis etc. did not occur . Subcutaneous hydrops came out in 12 cases. Conclusions Microsurgical resection by orbito-peronal approach is a favorable treatment for this kind of cranio-orbital tumors. Skull base reconstruction is one of the key to the successful surgery.
