PURPOSE: To compare the results of external dacryocystorhinostomy (DCR), using two different patterns of flap @entity254 with creation of both sac and nasal mucosal anterior and posterior flaps: one that includes suturing of both flaps and the other that involves excision of the posterior flaps. METHODS: This randomized, clinical trial included 63 consecutive @entity1 undergoing DCR. @entity1 were alternately assigned to two groups on the basis of the pattern of flap @entity254 . An H-shaped incision was created in the lacrimal sac and the nasal mucosa in all @entity1 . In group A, posterior and anterior flaps were separately approximated; in group B, only the anterior flaps were sutured after resection of both posterior flaps. @entity86 , @entity9467 , and patency of the tract were assessed on follow-up visits. Final scores and success rates of the two groups were compared by using the Mann-Whitney U and chi. RESULTS: The mean length of follow-up was 10.87 +/- 4.75 months for all @entity1 . One @entity1 in group B was lost to follow-up. The difference between the groups in @entity86 , @entity9467 , and patency scores was found to be statistically insignificant (p = 0.451, p = 0.974, p = 0.583, respectively). The final success rates in groups A and B were 93.75% and 96.67%, respectively. There was no statistically significant difference in success rate between the groups (p = 0.593). CONCLUSIONS: Our study suggests that DCR with double-flap @entity254 has no advantage over DCR with only anterior flaps. @entity254 by suturing only anterior flaps and excision of the posterior flaps is easier to perform and does not appear to adversely affect the outcome of DCR surgery.
