Primary Endonasal DCR Without Stent: Our Experience and Case Series Analysis.

Endonasal dacryocystorhinostomy is widely accepted and effective treatment option for nasolacrimal duct obstruction. It can be done with or without the use of stents. This study was carried out to evaluate the results of endonasal DCR surgery and to access efficacy of this procedure without stenting. This is a prospective clinical study conducted in Departments of ENT and Ophthalmology, L.N. Medical College and J.K. Hospital, Bhopal from October 2008 to April 2012. A total of 90 patients with epiphora as evidenced by nasolacrimal duct blockage on syringing were included in the study. These patients underwent endoscopic DCR without stenting. The cases were followed up to 18 months postoperative. Surgical success was defined as anatomical patency and symptomatic relief at the end of the follow up period. Failure was defined as no symptomatic relief, and/or acute dacryocystitis, and/or non patent lacrimal drainage system. Surgical success was observed in 80 of 90 (88.89 %) patients. Incidence of complication was low as only 6 patients had minor complication of bleeding, synechie and granulation tissue formation. It was concluded that high success rates could be achieved in case of nasolacrimal duct obstruction by endoscopic DCR. Thus, we can minimize complications, discomfort, the cost of stenting and follow up visits after endonasal DCR surgery.
