目的 研究巨大侵袭性垂体腺瘤的手术入路 ,探讨肿瘤全切除的方法 ,以及术后并发症的防治。方法 采用改良冠状开颅 ,经大脑纵裂、蝶窦入路。结果 施术 30例 ,肿瘤显微镜下全切除 2 2例 ,全切除率达 73%。 2 7例随访 2～ 3年 ,2 3例恢复正常工作 ,肿瘤无复发。结论 该手术入路充分显露蝶鞍、蝶窦、鞍旁及鞍后 ,是切除巨大侵袭性垂体腺瘤的较理想方法
Objective To study the surgical approach of giant invasive pituitary adenomas, to explore the methods of total tumor resection and the prevention and treatment of postoperative complications. Methods The improved coronal craniotomy was used for transcranial cleft transection and sphenoid sinus approach. Results Thirty patients underwent total tumor resection in 22 cases. The total resection rate was 73%. 2 7 cases were followed up for 2 to 3 years, 23 cases returned to normal work, and the tumor had no recurrence. Conclusions This surgical approach fully reveals the sella, sphenoid sinus, parasellar and posterior saddle. It is an ideal method for resection of giant invasive pituitary adenomas.
