Abstract

Introduction: The definitive management of complete nasolacrimal duct obstruction from chronic dacryocystitis is surgical. The surgery of choice is dacryocystorhinostomy (DCR), which can be done external or endonasal with or without stenting. We aim to compare the anatomical and functional outcomes of endoscopic endonasal DCR with and without stenting. Materials and Methods: This prospective study was carried out involving 30 patients of either sex randomly divided into two groups of 15 patients each. Group A underwent endoscopic DCR with stenting of the canaliculi, whereas Group B underwent endoscopic DCR without stenting. These patients were followed up at week 1, 6, and 12. The success of surgery in each group was determined by the absence of epiphora (Munk scale grades: 0 and 1), patent ostium on irrigation, positive Jones test, and decrease in the marginal tear film volume as seen on dye disappearance test (grade: 0 and 1) at week 12. Final data were analyzed using SPSS 21 version. Results: About 86.6% success rate was noted in the group where stenting was done (Group A) compared to 100% success in the group without stenting (Group B). This difference was, however, not statistically significant (P = 0.143). Failures in the study were attributed to the closure of rhinostomy ostium at week 12 follow-up. The most common complication noted was postoperative pain around the bridge of nose. Stent-related complications such as conjunctivitis and difficulty in removal of the stent were also noted. Conclusion: In our study, the surgical results of endoscopic endonasal DCR without stenting were better than endoscopic dacryocystorhinostomy with stenting both anatomically as well as functionally.
