目的 探讨颅底手术的重要解剖标志 ,保证颅底手术的安全性并彻底根治肿瘤。方法对我院 10年来 2 9例不同颅底手术进行回顾性总结 ,分析颅底的鸡冠、翼突和颞骨棘、茎突和颈内动脉及其各自的毗邻解剖结构在术前诊断、不同手术进路切除肿瘤时的应用情况。结果 本组初期3例手术中有 2例术后颅底有部分肿瘤残留 ;其余 2 6例颅底手术中 ,皆在直视下完全切除肿瘤 ,无手术死亡及严重颅脑并发症。本组 2 9例中 ,侵犯颅底的恶性肿瘤行不同的颅底手术 19例 ,其 3年生存率为 72 2 % (13/ 18) ,5年生存率为 35 7% (5 / 14 )。结论 鸡冠、翼突和颞骨棘、茎突和颈内动脉及其各自的毗邻解剖结构分别是不同的颅底手术重要标志 ,正确认识这些临床解剖标志是颅底手术安全成功的保证
Objective To explore the important anatomical landmarks of skull base surgery to ensure the safety of skull base surgery and radical cure of the tumor. Methods A total of 29 cases of skull base surgery in our hospital over the past 10 years were retrospectively reviewed. The results of preoperative diagnosis, operation of the coronoid, wing and temporal bone spine, styloid process and internal carotid artery and their respective adjacent anatomical structures in the skull base were analyzed. The application of tumor resection. Results The initial 3 cases of surgery in this group, 2 cases of postoperative skull base tumor residues; the remaining 26 cases of skull base surgery, under complete excision of the tumor, no operative death and severe brain complications. The group of 29 cases of malignant tumors of the skull base line in 19 cases of different skull base surgery, the 3-year survival rate was 72 2% (13/18), 5-year survival rate was 35 7% (5/14) . CONCLUSIONS: Cockscomb, pterygoid and temporal bone spine, styloid process and internal carotid artery and their respective adjacent anatomical structures are important signs of different skull base surgery. Correct understanding of these clinical anatomic landmarks is the guarantee of safe and successful skull base surgery
