Abstract |
PURPOSE To evaluate the surgical results and clinical effectiveness of silicone tube intubation through Hasner's valve under intranasal endoscopic guidance in children with congenital nasolacrimal duct obstruction (CNDO). METHODS: The present study enrolled a total of 58 eyes of 46 children over 12 months of age diagnosed with CNDO in the Department of Ophthalmology, Inje University College of Medicine from 2003 to 2010. Patients who had previously undergone ineffective probing or had a combination of an anatomical abnormality such as secondary nasolacrimal duct obstruction were also included. The silicone tube was intubated through the Hasner's valve and observed with intranasal endoscopy; tube retention time was planned for at least 12 weeks. RESULTS: A total of 20 eyes were previously probed preoperatively (mean 1.7 times). After the average follow-up period of 13.5 months, the overall success of silicone intubation was 57 of 58 eyes (98%). In one failed eye, nasolacrimal obstruction was already combined preoperatively, and unintentional tube removal by the patient occurred within one week. Silicone tube reintubation was performed after four months, and CNDO symptoms improved. CONCLUSIONS: Intranasal endoscopic observation to ensure the passage of a silicone tube through Hasner's valve decreases anatomical injury. When considering patient age and former treatment, silicone tube intubation with intranasal endoscopic observation could produce desirable results with a higher success rate. |
