Analysis on the efficacy of double probe lacrimal stent intubation in treatment of traumatic lacrimal duct obstruction after laser recanalization

Abstract

Objective To analyse the efficacy of double probe lacrimal stent intubation in treatment of traumatic lacrimal duct obstruction after laser recanalization. Methods During 2008 December to 2015 March, 105 eyes of 105 cases with traumatic lacrimal duct obstruction were collected.They were randomly divided into treatment group of 55 cases and control group of 50 cases. The treatment group received double probe lacrimal stent intubation after Nd: YAG laser recanalization, the control group underwent the laser recanalization only and application of lacrimal bolus Cortisone Ttracycline Ointment. Results All patients were followed up more than 6 months. Forty-nine cases (89.1%) were cured in the treatment group; in the control group 31 cases (62.0%) were cured. The difference in cure rate between the two groups was statistically significant (χ2=10.60, P=0.03). Complications: In treatment group, 5 cases of local swelling, bleeding occurred in 3 cases, 3 cases of pain and 1 cases of lacrimal stant extrusion; in control group local swelling occurred in 7 cases, 2 cases of hemorrhage and 1 cases of inflammatory subcutaneous induration. There was no statistically significant difference in complication (χ2=0.04, P=0.04). Conclusion The double probe lacrimal stent intubation can improve the success rate of traumatic lacrimal duct obstruction after Nd: YAG laser recanalization. The operation is convenient, with less complications. Key words: Lacrimal duct obstruction, traumatic; Recanalization, lacrimal duct, laser; Double probe lacrimal stent
