目的 介绍眶上锁孔入路显微手术切除鞍上区肿瘤的技术和经验。方法 选择鞍上区10例脑膜瘤和3例垂体腺瘤,经眶上锁孔入路,运用显微外科技术切除肿瘤,对周围结构妥善保护。结果 肿瘤全切除12例（92.3％）,大部分切除1例（7.7％）。除1例有短期尿崩外,余病例无术后感染、出血等手术并发症;术后住院时间明显缩短。结论 眶上锁孔入路对脑组织无效暴露少、牵拉轻、损伤小,术后并发症少,提高了手术安全性,有利于预后。
Objective To introduce the technique and experience of microsurgical removal of supraorbital tumor by supraorbital keyhole approach. Methods Ten cases of meningioma and three cases of pituitary adenoma in the suprasellar area were selected. The supraorbital keyhole approach was used. The tumor was removed by microsurgical technique and the surrounding structures were well protected. Results Total resection of tumors in 12 cases (92.3%), most of the resection in 1 case (7.7%). Except for 1 case of short-term diabetes insipidus, the remaining cases were free of postoperative infection, bleeding and other surgical complications. The postoperative hospitalization time was significantly shortened. Conclusion The supraorbital keyhole approach has less exposure to brain tissue, less traction, less injury and less postoperative complications, which improves the safety of operation and is beneficial to the prognosis.
