External versus Endoscopic Dacryocystorhinostomy for Acquired Nasolacrimal Duct Obstruction: A Comparative Study
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2018, Vol 6, Issue 6
Abstract
Purpose: The purpose of this study was to compare the success rates of endoscopic endonasal dacryocystorhinostomy (DCR) and external DCR in cases of acquired nasolacrimal duct obstruction. Design: This was a prospective randomized clinical study. Methods: A total of 58 consecutive patients were selected for DCR surgery. Among these, 30 patients underwent endonasal DCR and 28 patients underwent external DCR. Surgical success was defined by patients’ resolution of symptoms along with a patent lacrimal drainage system. Failure was defined as a lack of symptomatic reduction in epiphora and/or inability to irrigate lacrimal drainage system post-operatively. Results: Mean age of the patients was 38.64 years (34 ± 10.8 years). 81% of the study subjects were female and 19% were male. The success rate of endonasal DCR was 93.33% compared to a success rate of 92.85% in cases of external DCR (P = 0.898). Complication rate was low in both the groups. Conclusion: Endonasal DCR surgery is an attractive alternative to external DCR surgery with the advantages of a shorter operative time, lack of cosmetic scar, and equivalent success rate.
