Evaluation of Different Methods of Posterior Flap Management in External Dacryocystorhinostomy
Sponsor: Minia University
Summary
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.

6\. An H shaped incision at the postero-inferior lacrimal sac is made, with a long anterior flap and shorter posterior flap. Similarly an H shaped incision at the nasal mucosa is made. The posterior flap of lacrimal sac is sutured with posterior flap of nasal mucosa in interrupted fashion using 6-0 vicryl sutures in Group A, while in Group B the posterior flap is trimmed without suturing.
