前颅底-筛窦入路切除斜坡区硬膜外肿瘤

目的探讨前颅底-筛窦入路切除斜坡区硬膜外肿瘤的手术方法和技巧。方法对我院1999年11月至2006年7月间收治的10例斜坡区硬膜外脊索瘤病人均采用前颅底-筛窦入路显微手术治疗。结果10例肿瘤均达到镜下基本全切，无手术死亡病例，其中1例术后第7天出现脑脊液漏，重新手术修补成功。术后均无颅内感染及长期脑脊液漏等严重并发症发生，且均恢复良好。结论经前颅底-筛窦入路显微手术切除斜坡区硬膜外肿瘤具有可行性和优越性，对合适的病例可以做到彻底切除肿瘤，取得满意的效果。

Microsurgery through Anterior Skull Base-ethmoidal Sinus Approach For Extradural Tumors in Clival Regions

Objective To summarize microsurgical experience in removing the extradural tumors in the clival regions by microsurgery through anterior skull base-ethmoidal sinus approach. Methods The clinical data of 10 patients with clival region extradural tumors, who underwent microsurgery through the anterior skull base-ethmoidal sinus approach in our hospital from November, 1999 to July, 2006, were analyzed retrospectively. Results The total resection of the tumors was basically achieved in all the cases. No patients died from the operation. The cerebrospinal fluid leakage which occurred in 1 patient 7 days after the operation was successfully repaired. No severe complications including long-term cerebrospinal fluid leakage, intracraninal infection and so on occurred. Conclusions The microsurgery through anterior skull base-ethmoidal sinus approach is suitable for removing the neoplasms in the clival regions. The clinical practice of this approach has proved its feasibility and advantages including total resection of the tumors in the clival regions and satifactory outcomes.
