目的:探讨前颅底额眶筛区肿瘤切除的最佳手术入路。方法:采用扩大鼻外额窦进路术式对28例累及前颅底额眶筛区的肿瘤患者行肿瘤切除术。结果:经随访,8例良性肿瘤至今无复发或死亡,20例恶性肿瘤中,1年生存率95.0%(19/20),3年生存率61.5%(8/13),5年生存率57.1%(4/7)。结论:该术式术野暴露充分,手术时首先自前颅底剥离肿瘤阻断瘤体在颅底的血供,出血少,手术视野清晰,操作便捷,切除肿瘤彻底,重建颅底方便,手术创伤小,术后反应轻。该术式是切除前颅底额眶筛区肿瘤的较好手术入路。 Objective: To explore the optimal surgical approach for tumor resection in frontal skull base orbital orbital area. Methods: Tumor resection was performed in 28 patients with tumors involving frontal skull base orbital orbital floor by enlarging nasal frontal sinus approach. Results: No recurrence or death occurred in 8 cases of benign tumors. The 20-year survival rate was 95.0% (19/20), 3-year survival rate was 61.5% (8/13), and 5-year survival rate was 57.1 % (4/7). Conclusion: The operative field is well exposed. At the time of surgery, the tumor is stripped from the anterior skull to block the blood supply of the tumor at the base of the skull, less bleeding, clear surgical field, convenient operation, complete removal of the tumor, convenient reconstruction of the skull base, and surgical trauma Small, light reaction after surgery. The surgical approach is the best surgical approach for resection of frontal orbital orbital tumor.
