目的 :探讨鼻腔粘连对鼻窦内窥镜手术疗效的影响。方法 :应用Storz硬性鼻内窥镜 ,根据不同的病变部位 ,参照Messerklinger鼻内窥镜手术方法 ,行鼻内窥镜手术 84 5例 (15 5 8侧 ) ,术后定期随访 1年以上。结果 :治愈 12 80侧 ,总治愈率为 82 .2 %。其中Ⅰ型病例治愈率达 91%以上 ;Ⅱ型 1期和 2期分别为 98.9%和82 .8% ,3期为 75 .0 % ;Ⅲ型治愈率为 6 1.2 %。在 2 78侧无效病例中鼻腔粘连 15 1侧 ,占 5 4 .3%。结论 :鼻窦内窥镜术后鼻腔粘连以中鼻甲与其周围结构为主 ,导致鼻窦引流不畅 ,以致影响疗效 ,因此 ,减少术后局部粘连是提高手术疗效的关键。术中对中鼻甲的适当处理有助于减少术后粘连 ,提高手术效果 Objective: To investigate the effect of nasal adhesion on the efficacy of endoscopic sinus surgery. Methods: 845 cases (1558 sides) underwent endoscopic sinus surgery with reference to Messerklinger endoscopic sinus surgery with Storz rigid nasal endoscope. The patients were followed up for more than one year regularly. Results: 1280 sides were cured, the total cure rate was 82.2%. The cure rate of type I cases was above 91%. The type I and II stages were 98.9% and 82.8% respectively, the stage 3 was 75.0% and the type III was 6 1.2%. In 788 cases of invalid side of the nasal adhesions 151 side, accounting for 54.3%. CONCLUSIONS: Nasal cavity adhesions in nasal endoscope are mainly caused by the middle turbinate and its surrounding structures, resulting in poor drainage of the sinus and thus affecting the curative effect. Therefore, reducing the postoperative local adhesions is the key to improve the curative effect. Intraoperative treatment of middle turbinate can help reduce postoperative adhesions and improve the surgical results
