鼻内窥镜在改良泪囊鼻腔吻合术后的应用

Application of nasal endoscopy after modified dacryocystorhinostomy

目的探讨应用鼻内窥镜在改良泪囊鼻腔吻合术后换药和改良泪囊鼻腔吻合术后常规换药治疗慢性泪囊炎的疗效。方法93例慢性泪囊炎患者随机分为实验组行改良泪囊鼻腔吻合术联合术后鼻内窥镜下吻合腔换药47例；对照组行改良泪囊鼻腔吻合术后常规换药46例。术后均随访3～12个月。结果实验组47例治愈46例，好转1例，治愈率97．9％，对照组46例，治愈39例，好转5例，无效2例，治愈率84．8％。结论鼻内窥镜在改良泪囊鼻腔吻合术后应用安全、并发症少、效果良好，能提高手术成功率。

Objective To explore the efficacy of nasal endoscopy in change of medications for chronic dacryocystitis after modified dacryocystorhinostomy. Methods 93 patients with chronic dacryo- cystitis were randomly assigned to receive modified dacryocystorhinostomy plus either nasal endoscopy for change of medications （ 47 patients, study group ）, or conventional change of medications （ 46 patients, control group ）. All the patients were followed up for 3 to 12 months postoperatively. Results In the experimental group, 46 of the 47 patients were cured and the remaining one was improved, with a cure rate of 97.9%. while in the control group, 39 of the 46 patients were cured, 5 were improved, and 2 failed, with a cure rate of 84.8%. Conclusions Application of nasal endoscopy after modified dacryocystorhi nostomy is safe and efficions and has fewer complications. It can improve the success rate of the procedure.
