Abstract

Purpose: The aim is to compare the outcome of nonendoscopic endonasal dacryocystorhinostomy (NEN DCR) with external DCR (EXT-DCR) in the treatment of nasolacrimal duct obstruction (NLDO) in children.

Methods: A retrospective, comparative chart analysis of all consecutive children <16 years after EXT-DCR or NEN-DCR between June 2012 and February 2016.

Results: Seventy-one children (79 eyes) underwent DCR in the study, of which 37 children (40 eyes) underwent EXT-DCR and 34 (39 eyes) NEN-DCR. Mean age of both groups (8.7 vs. 7.7 years) was comparable. Etiologically, persistent congenital NLDO was the most common indication (50% vs. 72%), followed by acquired and secondary NLDO. Mean duration was shorter for NEN-DCR (47 vs. 37 min; P = 0.0021). Mitomycin C 0.04% was used more often in NEN-DCR (10% vs. 56.41%). Success after primary EXT-DCR was 100% as compared to 75% for primary NEN-DCR at median follow-up of 12 and 16 months respectively. At revision, the main cause of failure was granuloma (60%). After revision, all eyes were symptom-free at a median follow-up of 9.5 months.

Conclusion: Primary NEN-DCR has a poorer outcome than EXT-DCR in the treatment of NLDO in children and is more likely to need a revision procedure.
