目的　探讨鼻内窥镜手术治疗慢性鼻窦炎的疗效及影响疗效的相关因素。方法　对 1 996～2 0 0 1年间实施鼻内窥镜手术并完成随访的 350例慢性鼻窦炎、鼻息肉病人进行临床分析。 350例中 1型 1 1 0例 (31 5 % ) ,2型 1 61例 (45 9% ) ,3型 79例 (2 2 6 % )。 350例全部在局麻下完成 ,术后随访 6～ 36个月 ,平均1 3个月。同时对术后处理、钩突异常等因素进行了讨论。结果　 1型治愈率为 91 8% ,2型治愈率为81 9% ,3型治愈率为 69 6 %。结论　鼻内窥镜手术是治疗慢性鼻窦炎、鼻息肉的有效方法。其发病与钩突密切相关。手术疗效与其临床分型密切相关 Objective To investigate the curative effect of nasal endoscopic surgery on chronic sinusitis and related factors that affect curative effect. Methods Clinical data of 350 patients with chronic sinusitis and nasal polyps who underwent endoscopic sinus surgery and were followed up from 1996 to 2001 were analyzed retrospectively. Of the 350 cases, 110 were type 1 (31.5%), 61 were type 2 (45.9%), and 79 (23.6%) were type 3. 350 cases were completed under local anesthesia, followed up for 6 to 36 months, an average of 13 months. At the same time, postoperative treatment, abnormalities of uncinate process and other factors were discussed. Results The cure rate of type 1 was 91.8%, that of type 2 was 81.9%, and that of type 3 was 69.6%. Conclusion Endoscopic sinus surgery is an effective method for the treatment of chronic sinusitis and nasal polyps. Its incidence is closely related with uncinate process. Surgical efficacy and its clinical classification is closely related
