Abstract

AIM To comparatively evaluate the surgical outcome of external dacryocystorhinostomy with two different flap techniques (H/ double vs U/single) with respect to surgical time. STUDY DESIGN Prospective randomized comparative clinical study
MATERIAL AND METHOD 96 patients of primary NLD block were selected. 47 underwent the conventional DCR by 'H' Shaped flap and 49 by 'U' Shaped flap with suspension to the orbicularis. Success rate was evaluated by lacrimal patency to irrigation and surgical time was calculated from skin incision to skin suturing.
RESULTS Success rate in groups A and B was 93.62% and 95.91% respectively. Surgical time difference between the groups was statistically significant while difference in complication rate was not significant.
