目的：探讨鼻内窥镜修正术治疗复发性鼻息肉的疗效和手术体会。方法：回顾分析１９９７年７月－１９９８年１０月间２１例因鼻息肉复发在我院行鼻内窥镜修正术的患者，２１例均双侧同时手术，根据ＣＴ所见及术中情况，采用筛窦全切或次全切，上颌窦自然窦口扩大，尖牙窝径路上颌窦病变组织清除等手术方式。结果：随访６－１２个月评定疗效，治愈７傅，好转８例，无效６例，总有效率７１．４％，无一例出现严重并发症。结论：鼻内窥镜

Revision endoscopic sinus surgery for recurrent nasal polyps

OBJECTIVE: To study the surgical effect and experience of revision endoscopic sinus surgery for the patients with recurrent nasal polyps. METHOD: From Jul. 1997 to Oct. 1998, a subset of 21 cases with recurrent nasal polyps had been operated by the way of revision endoscopic sinus surgery. All the patients were operated bilaterally at the same time. The operation type included: total ethmoidectomy or sub-total ethmoidectomy, maxillary natural orifice enlargement and maxillary sinus pathological changes tissue eliminated by canine fossa access. RESULT: We have followed these patients for 6-12 months and evaluated surgical effect: 7 cases of 21 were cured, 8 were improved, 6 were of no effect, and the total effective rate was 71.4%. There are not any heavy complications in this subset. CONCLUSION: Revision endoscopic sinus surgery is an effective way for recurrent nasal polyps patients, six anatomic marks proposed by May will do good for us to resect the pathological changes tissue thoroughly and prevent heavy complications as could as possible.
