Purpose: To report the authors’ experience with endoscopic unpowered dacryocystorhinostomy in the treatment of pediatric nasolacrimal duct obstruction, and to evaluate whether surgical site reassessment (after the appropriate healing period) affects clinical outcomes. Methods: This retrospective study included 47 children aged between 1.5 and 17.0 years (mean age: 6.9 years) who underwent endoscopic unpowered dacryocystorhinostomy between 2014 and 2019 at one tertiary care hospital. Twenty-six patients required unilateral and 21 required bilateral endoscopic dacryocystorhinostomy. The main outcome measures were duct patency on lacrimal irrigation (“anatomical success”) and resolution of symptoms (“clinical success”) over 6 months of postoperative follow-up. Results: Sixty-eight dacryocystorhinostomy procedures were performed. Surgical site reassessment during tube removal was performed in 52 of 68 cases. Five cases (9.6%) required treatment of local pathologies, only after which was symptomatic relief achieved. Overall anatomical success was observed in 49 (94.2%) of the 52 cases in which nasal endoscopy was performed, including the 5 cases treated during reevaluation. Clinical success was observed in 63 (92.6%) cases. Conclusions: Pediatric endoscopic dacryocystorhinostomy is an effective surgical procedure used to correct nasolacrimal system obstruction resistant to conservative measures. The unpowered endoscopic dacryocystorhinostomy technique is practical and safe in the pediatric population. Surgical site reassessment allows treating local pathologies threatening ostium patency and increases clinical success rates.
