Evaluation of Different Methods of Posterior Flap Management in External Dacryocystorhinostomy

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.
