AIM: To explore the usefulness of RS-type lacrimal drainage tube versus double silicone tube for children's lacrimal canaliculi rupture.

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.
