The Enlarging Modified Pterional Keyhole Approach for Removing the Tumors in the Middle Skull Base and Seller Region
-
摘要: 目的:总结近3年来采用扩大改良翼点入路切除中颅凹底及鞍区肿瘤的经验和体会。方法:1例海绵状血管瘤和1例中颅凹底脑膜瘤行颧弓翼点外,其余均行眶颧弓入路切除肿瘤。结果:除2例海绵状血管瘤大部分切除外,其余肿瘤均在显微镜下全切;全组无手术死亡。术后视力好转5例,恶化1例,尿崩3例,偏瘫均不同程度恢复,2例局部积液。结论:扩大改良翼点入路有暴露肿瘤充分,全切率高,并发症少等特点,据肿瘤的生长特点,可选择适当的手术方法,适合于中颅凹底及鞍区相临近部位的肿瘤切除。

Abstract: Objective : To summarize our experience on the enlarging modified pterional keyhole approach for removing the tumors in the middle skull base and seller region. Methods : One cavernous hemangioma and one middle skull base meningioma were removed via zygomatic pterional keyhole approach. The others were removed via orbitozygomatic approach. Results : Subtotal resection was performed for two cases of cavernous hemangiomas. Total resection of the tumors was achieved in the other cases. There was no death associated with operation. 5 cases with visual disturbance improved after surgery and one case worsened. The cases with hemiparesis improved after surgery. Conclusion:By using this approach, the tumors could be displayed maximally under microscope, the rate of total resection is higher than by others and the postoperative complication were rare. This approach is the ideal method for surgery of the tumors in the middle skull base and seller region. -
