方法：回顾性分析2008-03/2011-03来我院136例136眼慢性泪囊炎患者手术治疗的效果，其中行鼻内窥镜下泪道扩张引流管植入联合鼻腔泪囊造孔术66例，行改良鼻腔泪囊吻合术70例，均为单侧慢性泪囊炎。

结果：鼻内窥镜下泪道扩张引流管植入联合鼻腔泪囊造孔术治愈60例，好转5例，无效1例，治愈率达90.9%，有效率达98.5%； 改良鼻腔泪囊吻合术治愈64例，好转4例，无效2例，治愈率达91.4%，有效率达97.1%。采用χ²检验，两组比较差异无统计学意义(P>0.05)。

结论：鼻内窥镜下泪道扩张引流管植入联合鼻腔泪囊造孔术与改良鼻腔泪囊吻合术治疗慢性泪囊炎的疗效接近，但鼻内窥镜下泪道扩张引流管植入联合鼻腔泪囊造孔术无需面部皮肤切口，创伤小，出血少，值得推广。

METHODS: The effect of operation treatment of 136 chronic dacryocystitis patients in recent 3 years was retrospectively analyzed. 66 patients underwent the treatment of dilating lacrimal drainage tube implantation and nasal cavity dacryocyst pore under nasal endoscope. 70 patients underwent the treatment of improvement of lacrimal sac and nasal cavity anastomosis. All of the patients were unilateral chronic dacryocystitis.

RESULTS: Dilating lacrimal drainage tube implantation and dacryocystorhinotomy under nasal endoscope: 60 patients were cured; 5 patients were improved; 1 patient was invalid. The cure rate was 90.9%, effective rate 98.5%. Improvement of lacrimal sac and nasal cavity anastomosis: 64 patients were cured, 4 patients were improved, 2 patients were invalid, the cure rate was 91.4%, and effective rate was 97.1%. By using Chi-square test, P>0.05, there were no significant differences between the two groups.

CONCLUSION: There are the treatment effects of proximity about dilating lacrimal drainage tube implantation and dacryocystorhinotomy under nasal endoscope and improvement of lacrimal sac and nasal cavity anastomosis. But the operation of dilating lacrimal drainage tube implantation and dacryocystorhinotomy under nasal endoscope have small wound, less bleeding, without skin incision, which is worthy of clinical application.
