Abstract:

Objective To analyze the clinical effect of the microdrill combined with artificial nasolcrimal duct implantation with the fifth generation lacrimal endoscopy on the nasolcrimal duct obstruction. Design Prospective comparative case series. Participants 117 patients with nasolcrimal duct obstruction. Methods The patients were randomly divided into observation group (endoscopic lacrimal microdrill with artificial nasolcrimal duct group, 61 cases 61 eyes) and control group (dacryocystorhinostomy group, 56 cases 56 eyes). Their clinical effects were compared after the treatment. The follow-up period was 6 momths. Main Outcome Measures The effective rate and the complication rate. Results In the observation group and the control group, the effective rate (cure rate + improvement rate) was 92.1% and 74.7%, respectively(P=0.178); the complication rate was 17.1% and 47.2%, respectively (P=0.000). Conclusion This short-term follow-up results showed that the treatment of microdrill and artificial nasolcrimal duct implantation for nasolcrimal duct obstruction with the new generation lacrimal endoscopy was effective, safe.
