方法：将80例80眼慢性泪囊炎随机分为两组。A 组(鼻泪管支架植入术)40例； B 组(鼻内窥镜下鼻腔泪囊吻合术)40例。术后对其疗效进行追踪观察，检查泪道通畅情况。

结果：术后随诊1a。术后6mo； 1a，A组有效率分别为90%，85%； B组有效率分别为97.5%，100%。术后6mo，A，B组两间比较差异无统计学意义(P>0.05)。术后1a，A，B两组间比较差异有统计学意义(P<0.05)。

结论：鼻内窥镜下鼻腔泪囊吻合术较鼻泪管支架植入术治疗慢性泪囊炎的疗效更可靠。

METHODS: Totally 80 cases(80 eyes)with chronic dacryocystitis were randomly divided into two groups. There were 40 cases in group A(nasolacrimial duct stent placement), 40 cases in group B(dacryocystorhinostomy under nose endoscope). The treatment effects were observed after operation. The graft patency of lacrimal passage was examined post operatively.

RESULTS: Patients were followed up for 1 year. The effective rate of group A was 90%, 85% at six month and 1 year after the operation respectively. Effective rate of group B was 97.5%, 100% at six month and 1 year after the operation respectively. There was no statistically significant difference between the two groups at six month(P>0.05), while there was statistically significant difference at one year(P<0.05).

CONCLUSION: The effect of dacryocystorhinostomy under nose endoscope is more reliable than nasolacrimial duct stent placement for chronic dacryocystitis.
