目的探讨切除鞍区大型肿瘤的手术方法。方法采用经双额叶底－内侧入路治疗８例鞍区不同病理性质肿瘤，手术要点：①作全冠状皮肤切口，形成跨中线额低骨瓣，结扎前矢状窦、剪断大脑镰。②自双额底游离嗅神经至嗅三角。③自底内向外上牵开双额叶，暴露肿瘤，必要时截断前交通动脉。结果本组８例中肿瘤全切除５例，次全切除３例，术后症状不同程度改善。结论本入路由于手术视野明显扩大，适用于鞍区大型肿瘤的手术治疗。
Objective To investigate the surgical method of resecting large tumors in the sellar area. Methods Eight cases of different pathological tumors in the sellar area were treated by double frontal-medial approach. The main points of surgery were: (1) making a full-corneal skin incision to form a transversal median frontal lobe with a sagittal sinus before the ligation and clipping the falx. ② from the double bottom of the free olfactory nerve to olfactory triangle. ③ from the inside out on the double frontal lobes, exposing the tumor, if necessary, cut off the front traffic artery. Results The group of 8 cases of tumor resection in 5 cases, subtotal resection in 3 cases, postoperative symptoms improved to varying degrees. Conclusion Due to the obvious enlargement of operative field, this approach is suitable for the surgical treatment of large tumors in the saddle area.
