摘要

AIM: To compare the outcomes achieved with external dacryocystorhinostomy(EX-DCR) and transcanalicular dacryocystorhinostomy(TC-DCR) using a multidiode laser in patients with bilateral nasolacrimal duct obstruction(NLDO).METHODS: This prospective study was conducted on38 eyes of 19 patients with bilateral NLDO. Simultaneous bilateral surgery was performed on all patients. TC-DCR(Group 1) with a diode laser was used in the right eye,and EX-DCR(Group 2) was used in the left eye. All patients were placed under general anesthesia. Routine follow-ups were scheduled at 1wk; 1, 3, 6 and 12 mo postoperative intervals. Objective(lacrimal system irrigation) and subjective [tearing, irritation, pain,discharge and visual analogue scale(VAS) score]outcomes were evaluated.RESULTS: The overall objective success rate at 12 mo was 73.7%(14/19) in Group 1 and 89.5 %(17/19) in Group2. This difference was statistically significant. There were no significant between-group differences in the subjective results, such as tearing, pain and irritation.Only the discharge scores were found to be significantly higher in Group 1 compared to Group 2 at the 1y followup. The average VAS score was 6.8 in Group 1 and 8.7 in Group 2, with no statistically significant differences.CONCLUSION: Although TC-DCR allows surgeons to perform a minimally invasive and safe procedure, EX-DCR offers better objective and subjective outcomes than TC-DCR.
