BACKGROUND: Epiphora secondary to acquired @entity1448 is a common ophthalmic problem in adults requiring surgical management. External dacryocystorhinostomy (DCR) is a reliable but difficult surgical technique for the treatment of @entity1448 . PURPOSE: To evaluate the success rate and complications of modified external DCR in @entity1 with primary acquired @entity1448 . MATERIALS AND METHODS: This hospital based prospective interventional study included 56 @entity1 with primary acquired @entity1448 . Diagnosis of @entity1448 was made through irrigation of the nasolacrimal drainage system. All @entity1 were operated by modified technique of external DCR with @entity254 of the anterior lacrimal and nasal mucosal flaps only, whereas @entity33 were excised. @entity1 were followed up for a period of 6 months. During the follow up, success rate and complications if any were recorded. Success was defined objectively by a patent lacrimal passage on irrigation and subjectively by the absence of watering or discharge. RESULTS: The mean age of the study population was 39.23    10.66 years, and 78.6% of @entity1 were females (male to female ratio 1:3.7). The average operation time was 36.48    4.72 minutes. Objective and subjective success rates were 92.9% and 89.3%, respectively after a follow up period of 6 months. Intraoperatively, @entity548 occurred in 3 @entity1 (5.3%) and laceration of the nasal mucosa in 4 @entity1 (7.1%). @entity260 included significant lid swelling and periorbital ecchymosis in 3 @entity1 (5.3%), @entity1415 in 2 @entity1 (3.6%) and @entity2805 in 2 @entity1 (3.6%). CONCLUSION: These results suggest that modified external DCR with anterior flaps @entity254 only is a simple, safe, less time consuming surgical technique that is easy to perform, and the outcome is comparable to conventional DCR.
