Abstract

Background and Objectives: To evaluate the success rate of the therapeutic effectiveness and safety of endoscopic dacryocystorhinostomy to treat obstruction of the lacrimal pathway.

Methods: The study involved prospective randomized case series. Operative and postoperative data were prospectively collected on 114 patients (120 eyes) who presented to Rizgary Teaching Hospital (Erbil city – Iraq) with epiphora and obstruction of the nasolacrimal system, from February 2013 until October 2017. All patients consecutively underwent endoscopic dacryocystorhinostomy. The follow-up evaluation included system evaluation and endoscopic assessment of the newly created ostium; the follow-up was done at 1 week, 1 month, and 3 months postoperatively, and results were compared between the different groups.

Results: A total of 120 cases of endoscopic dacryocystorhinostomy were performed on 114 patients. Procedure success rate was around 95.8%using a powered drill and endoscopic system with minimum complication. The age group of 25-44 years (45.8%) is the higher percentage and the female gender accounts for 83.3%. No complications were recorded in78.3% of the patients, while 10% had developed granulation tissue at the fistula site. Only 5%of the cases suffered from synechia and 5.7%were miscellaneous complications. No statistically significant differences were found between the surgery and age, gender, or side of the operation.

Conclusion: Powered endoscopic dacryocystorhinostomy is the most suitable treatment for patients at the level of the sac or in the nasolacrimal duct obstruction.
