Dacryocystorhinostomy combined lacrimal laser plasty and silicone intubation implantation for lacrimal multi-point obstruction

Abstract

AIM: To evaluate therapeutic effects of dacryocystorhinostomy combined lacrimal laser plasty and silicone intubation implantation for lacrimal duct with multi-point obstruction.METHODS: Thirty-five patients with one or more point obstruction in upper lacrimal duct received lacrimal laser plasty at first. Then, when the obstruction was broken, modified surgery of dacryocystorhinostomy combined silicone intubation implantation in the both lacrimal ductule was performed. Irrigating of the lacrimal passage was made regularly after operation. The silicone tube was extracted in 4 weeks. The follow-up time was 6 months. RESULTS: There were no intraoperation complications and the silicone tube did not fall off after operation. Irrigating test results of lacrimal passage showed 30 out of the 35 eyes(86%)were cured, improved in 3 cases, 2 cases was ineffective. The cure rate was 86% and the efficiency was 94%. CONCLUSION: Dacryocystorhinostomy combined lacrimal laser plasty and silicone intubation implantation is an effective treatment for lacrimal duct with multi-point obstruction, there are less operation complications and higher rate of recanalization of lacrimal passage.
