Endoscopic dacryocystorhinostomy using mucosal flaps for bilateral overlapping.

Background: Recently, the use of posterior mucus flap has been introduced as a new technique for DCR, which has had a great success, as well as bone overlapping and minimal postoperative obstruction. Considering the need for these flaps to have a very good success, the purpose of this study was to examine the DCR endoscopic method using mucosal flaps for double-sided overlapping (as a new flap).

Methods: In this clinical trial study, 60 patients undergoing DCR endoscopy referring to Amin and Al-Zahra hospitals during 1396 to 1398 entered the study.
