目的：比较RS管泪道再通管(RS-type lacrimal intubation，RS管)和环形泪管在儿童泪小管断裂吻合术中的临床疗效。

方法：回顾性分析2016-08/2018-07我院收治的泪小管断裂患儿37例37眼的临床资料。治疗组20例20眼行RS管置入术，对照组17例17眼行环形泪管置入术，比较分析两种泪道置管术的临床效果和并发症情况。

结果：治疗组和对照组术中鼻黏膜出血率分别为0和100%。治疗组和对照组治疗有效率分别为95%和88%(P=0.584)。治疗组和对照组术后并发症率分别为5%和12%(P=0.584)。

结论：RS管置入术可有效避免鼻黏膜出血情况发生，操作简便、易拔管、并发症少、安全性高、效果好，适宜在基层医院广泛推行。

METHODS: A retrospective analysis from August 2016 and July 2018 were taken. Totally 37 children(37 eyes)of lacrimal canaliculi rupture were enrolled in the study and divided into two groups according to admission time sequence: treatment group(20 eyes)and control group(17 eyes). The treatment group was treated with RS-type lacrimal drainage tube. The control group underwent the implantation of double silicone tube and their efficacy was analyzed.

RESULTS: It was significant difference that the epistaxis rate between the treatment group and the control group, which was 0% and 100%. The effective rate was 95% and 88%, respectively, for the treatment group and the control group, the difference between the two groups has no significant(P=0.584). And the postoperative complication rate was 5% in treatment group, 12% in control group respectively, there was no significant statistical difference between the two groups(P=0.584).

CONCLUSION: The implantation of the RS-type lacrimal drainage tube can effectively prevent epistaxis, is safe and simple, easy to operate and extubate easily with good clinical effect in the treatment of lacrimal canaliculus fracture in children. So it can be widely carried out in basic hospitals.
