Abstract

Purpose
To assess the clinical outcomes of fibrin glue in endonasal dacryocystorhinostomy (DCR) for patients with primary nasolacrimal duct obstruction and to compare the surgical success rates between groups with the lacrimal sac flap using fibrin glue and without flap formation.
Methods
In this prospective study, a total of 45 patients (63 eyes) underwent endonasal DCR. Fibrin glue was applied to the mucosal flap at the osteotomy site in the nasal cavity. The subjects were divided into two groups: group 1 (with lacrimal sac flap using fibrin glue), consisting of 20 patients (28 eyes), and group 2 (without flap), including 25 patients (35 eyes). To evaluate the two groups, subjective symptoms were asked to the patients, and endoscopic examinations were performed.
Results
There were no statistically significant differences observed in terms of age, sex, timing of tube removal, or follow-up period between the groups. Group 1 showed significantly better results compared to the control group in terms of the degree of granuloma observed at 6 months postoperatively and the level of patient discomfort reported at 3 months postoperatively.
Conclusions
Endonasal DCR with the lacrimal sac flap using fibrin glue achieves higher functional success, reduces patient discomfort at 3 months postoperatively, reduces granuloma formation at 6 months postoperatively, and improves membranous closure compared to flapless surgery.
