筛窦入路斜坡及鞍底巨大脊索瘤的颅底手术

目的：探讨斜坡及鞍底巨大脊索瘤的手术治疗方法。方法：经筛窦入路手术治疗3例上斜坡肿瘤，其中1例复发性巨大斜坡肿瘤，累及鞍底、筛窦及整个鼻腔，经筛窦入路加左侧鼻旁侧切。结果：3例均达到镜下全切，1例术后第7天出现脑脊液漏，后重新修补，4周后痊愈出院。无长期脑脊液漏及颅内感染。结论：前额正中筛窦入路切除斜坡、鞍底肿瘤、符合解剖特点，显露充分，避免了颅底两侧血管神经的损伤，不造成脑组织损伤，肿瘤切除彻底，效果好。

Resection of Giant Chordoma via the Transethmoidal Approach

Objective:To discuss a transethmoidal surgical approach for chordomas involving the clivus and the sella turcica region . Methods: Three patients with giant chordoma involving anterior cranial fossa, middle cranial fossa and posterior cranial fossa, who were treated via transethmoidal surgical approach, were retrospectively studied. Results: All the tumors were totally removed microsurgically with this approach. No death or severe complications occurred. Conclusion: This approach is sufficient in the exposure of clivus and sella turcica region, less destructive,less time - consuming and easy to perform.
