目的　探讨筛蝶窦斜坡区肿瘤的手术入路及切除。方法　采用双额单骨瓣联合眉弓眶顶骨瓣前颅底扩大入路暴露肿瘤，即在传统双额骨瓣的基础上附加双侧眉弓眶顶骨瓣。术野暴露低而广泛，在减少向上抬起额叶的情况下分块切除肿瘤，然后给予颅底重建。结果　９ 例肿瘤中全切除５ 例，次全切除３ 例，大部切除１ 例。无手术死亡，无长期脑脊液漏和颅内感染。结论　此入路暴露肿瘤充分，可直接从前方或下方接近并切除肿瘤，对脑组织牵拉损伤小。 Objective To investigate the surgical approach and resection of sphenoidal sinus slope tumors. Methods Bilateral single bone flap combined with the anterior skull base of the eyebrow arch was used to expose the tumor. Bilateral eyebrow arches were added to the traditional bifrontal bone flap. The operative field is low and wide-ranging, and the tumor is removed in blocks and the skull base is reconstructed. Results Totally 9 cases had total resection in 5 cases, subtotal resection in 3 cases, and major resection in 1 case. No operative death, no long-term cerebrospinal fluid leakage and intracranial infection. Conclusions This approach has adequate exposure to tumors, and can be approached and resected directly from the front or the bottom, with minimal traction damage to the brain tissue.
