Aims and objectives: To compare the success rate and complications between external and endonasal DCR.
Materials and methods: The study included 50 cases in 49 patients. They were randomized into 2 groups. Group A for external DCR and group B for endonasal DCR. Post op evaluation was done after 1st & 2nd week and 2nd& 3rd month for presence or absence of watering or discharge and patency of sac was assessed by syringing.
Results: We had equal success in group A and group B of 22 cases each (88%). Most common cause of failure in group A was excessive scarring whereas in group B was obstruction of rhinostomy by granulation tissue.
Discussion: The primary success rate with external or endonasal DCR is found to be the same. The complications in both the procedures were very few and occurred at a very low rate.
Conclusion: Both methods represent good alternatives of treatment for Primary nasolacrimal sac and duct obstruction or chronic dacryocystitis..
