Effect of minimally invasive cacrimal duct recanalization combined with silicone tube intubation on lacrimal duct obstruction / 实用医学杂志

ABSTRACT

Objective To explore the clinical effect of lacrimal endoscope assisted minimally invasive lacrimal duct recanalization combined with silicone tube intubation in the treatment of lacrimal duct obstruction. Methods 3 cases(4 eyes)of the superior canaliculus obstruction,5 cases(6 eyes)of the inferior canaliculus,20 cases (29 eyes) of common canaliculus and 25 cases (36 eyes) of nasolacrimal duct were enrolled. They were randomly divided into two groupsGroup A(40 eyes)treated with lacrimal endoscope assisted laser lacrimal forming combined with silicone tube implantation and Group B(36 eyes)with lacrimal endoscope assisted laser lacrimal forming combined with silicone tube implantation. The cases were all followed up for 3-6 months after treatment. Results Except the intraoperative bleeding,there were no significant differences in the incidence of various complications. All the eyes could be recanalized under the aid of lacrimal endoscope. The total effective rates were 87.50% and 91.43% in Group A and B,respectively. The difference was not statistically significant. Conclusion Lacrimal endoscope assisted minimally invasive lacrimal duct recanalization combined with silicone tube intubation is a safe,effective,and minimally invasive method to recanalize the lacrimal obstruction.
