方法：选取2011-12/ 2014-12我院收治的慢性泪囊炎合并鼻泪管阻塞患者70例70眼，随机分为对照组与研究组，对照组患者行鼻内窥镜下鼻腔泪囊吻合术治疗，研究组患者行鼻内窥镜下鼻腔泪囊吻合置管术治疗，对比两组患者术后1、6、12mo时治疗总有效率及瘘口面积。

结果：术后1mo，对照组患者治疗总有效率97%与研究组100%，差异无统计学意义(P>0.05)； 术后6mo，研究组患者总有效率97%与对照组77%，差异有统计学意义(P<0.05)； 术后12mo，研究组总有效率94%明显高于对照组71%，差异有统计学意义(P<0.05)。两组患者术后1mo瘘口面积对比无统计学意义(P>0.05)，研究组患者术后6、12mo瘘口面积大于对照组，差异有统计学意义(P<0.05)。

结论：慢性泪囊炎合并鼻泪管阻塞患者行鼻内窥镜下鼻腔泪囊吻合置管治疗的效果显著。

METHODS: Totally 70 patients(70 eyes)with chronic dacryocystitis and nasolacrimal duct obstruction in our hospital from December 2011 to December 2014 were selected, and were randomly divided into control group and study group. The control group were treated with nasal cavity lacrimal sac anastomosis under nasal endoscope, and the study group were treated with nasal lacrimal sac anastomosis combined with tube insertion under nasal endoscope. Total effective rates and fistula areas at 1, 6 and 12mo before and after operation were compared between the two groups.

RESULTS: At 1mo after operation, there was no significant difference in total effective rates between the control group(97%)and the study group(100%; P>0.05). At 6mo after operation, the total effective rate in the study group(97%)was significantly higher than that in the control group(77%; P<0.05). At 12mo after operation, the total effective rate in the study group(94%)was significantly higher than that in of the control group(71%; P<0.05). There was no significant difference in fistula areas between the two groups at 1mo after the operation(P>0.05), while fistula areas in the study group were larger than those in the control group at 6 and 12mo after operation(P<0.05).

CONCLUSION: The effects of nasal lacrimal sac anastomosis combined with tube insertion under nasal endoscope on patients with chronic dacryocystitis and nasolacrimal duct obstruction are remarkable.
