Abstract :

To compare the surgical outcome with respect to time in H(double) and U(single) flap technique in external dacryocystorhinostomy a prospective randomized clinical study was done with 96 patients of which 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 calculated from skin incision to skin suturing . Statistical analysis was done by Chi–square test, T–test and Fisher�s exact test.Success rate in groups A and B was 93.62% and 95.91% respectively. Surgical time difference between the groups was statistically significant with t =7.2031, p= 0.0001(<0.05) while difference in complication rate was not significant (X2 test=0.733 p=0.391).External dacryocystorhinostomy with H flap has no advantage over the U flap which is much easier with significantly less surgical time and improved success rate.
