Evaluation of Different Methods of Posterior Flap Management in External Dacryocystorhinostomy

Overview

The aim of DCR is to form a new, mucosa-lined pathway between the lacrimal sac and the nasal cavity where tears can bypass a lacrimal obstruction and drain directly in the nose. The original external approach was described in 19046. In 1920s, mucosal flap anastomosis was added to the procedure as a modification7, and since then, many new modifications have been made to improve the original procedure.

Aim of The Study • To compare intraoperative details and postoperative endonasal endoscopic findings and their effects on success rate of external dacryocystorhinostomy with and without anastomosis of posterior mucosal flaps. Patients and Methods Study Design: This will be a prospective interventional comparative clinical study. It will include two groups according to the surgical procedure:- Group A: includes 30 eyes that will be treated with external DCR with anastomosis of posterior mucosal flaps . Group B: includes 30 eyes that will be treated with external DCR with amputation of posterior mucosal flaps . Study Population: Study participants will be: 60 eyes undergo external DCR . All patients included in this study will be verbally briefed about the details and the nature of the study \& will sign a written consent according to the local Ethics Committee of Minia University Faculty of Medicine. The study will be conducted in Ophthalmology department, Minia university Hospital, Egypt.
