OBJECTIVES: This study evaluates the outcomes of a one-stage obstruction-based strategy for congenital nasolacrimal duct obstruction (CNLDO) in children who have prior probing failure. The objective is to assess the success rates of probing, balloon dacrioplasty (BDP), monocanalicular intubation (MCI), and external dacryocystorhinostomy (external DCR) performed in the same anesthesia session.
METHODS: A retrospective analysis included 55 eyes (45 patients, aged 12–120 months) with initial probing at another center. Procedures involved probing, probing plus BDP, MCI, and external DCR. For membranous obstruction (MO), the procedure concludes after probing; for incomplete complex obstruction (ICO) it includes BDP or MCI; and for complete complex obstruction (CCO), external DCR is performed. Success rates were assessed based on obstruction types and age groups, with improvement in symptoms and signs as the measure of success. Statistical analysis utilized Kruskal–Wallis, Fisher’s exact test, and logistic regression.
RESULTS: The overall success rate for all procedures was 72.7%. Success rates were 77.8% for MO, 66.7% for ICO, and 100% for CCO, introducing a promising perspective for the management of different CNLDO types. External DCR ex-hibited a 100% success rate, highlighting its effectiveness in cases of CCO. Success rates for interventions were 77.8% for probing, 61.5% for probing plus BDP, and 73.1% for MCI, emphasizing the feasibility and success of one-stage obstruction-based treatments. Age did not significantly correlate with success rates.
DISCUSSION AND CONCLUSION: The one-stage obstruction-based approach, which demonstrated favorable success rates in treating CNLDO and introduced a paradigm shift in the treatment strategy after probing failure, underscores the importance of tailoring interventions to the specific obstruction type. The study also highlights the feasibility and cost-effectiveness of performing multiple BDP, MCI, or external DCR procedures concurrently during the same anesthesia session, further emphasizing the crucial role of customizing treatments based on the nature of the obstruction.
