INTRODUCTION Endoscopic DCR is routinely performed by otolaryngologists for the treatment of chronic dacryocystitis. However, postoperative stenosis and failure rates are common. OBJECTIVE The objective of our study is to evaluate the role of preserving the mucosal flap in maintaining the patency of neo ostium. The surgical technique involved the creation of nasal mucosal and large posterior lacrimal flaps at the medial lacrimal sac wall and the two flaps were placed in close apposition. Success was defined as complete resolution of epiphora and a patent lacrimal system, evaluated by lacrimal irrigation and endoscopy followed upto 1 year postoperatively. MATERIALS AND METHODS A prosective study was conducted in 60 patients and followed for a duration of 1 year in ENT department,KMC,Guntur RESULTS In our study, Symptomatic and anatomic success was seen in 59 out of 60 operations that is 98% success in syringing patency was seen with this technique, which is comparable to external DCR and better than other endoscopic techniques. CONCLUSION Mucosal flap preservation appears to be the single most important innovation in endoscopic DCR surgery, which makes it comfortable for both the surgeon and patient, apart from providing a 98% success rate in our study.
