BackgroundPediatric nasolacrimal duct obstruction (PNDO) requires therapeutic intervention after conservative procedures failed. As resilient treatment guidelines for the treatment are missing, the aim of this study was to evaluate the advantages of two different intervention techniques in children with PNDO.MethodsBetween January, 2006 and June, 2014, 233 children (0-208 months) were treated either with conventional probing by ophthalmologists only (Group I) or with endonasal endoscopic interdisciplinary approach (Group II). The clinical outcome was analyzed.ResultsThe overall success rate of Group I was 93.4% compared to 98.4% of Group II (P<0.05). 50% of all interventions (n=62) of Group II required further surgical procedures in addition to probing/irrigation, particularly with regard to children <6 and >24 months.ConclusionsEndoscopic control in treatment of PNDO allows exact identification of the stenosis and appropriate surgical intervention with an improved clinical outcome. Endonasal endoscopic surgical techniques should be the standard PNDO treatment.
