Abstract. Purpose:To report the outcome of treatment for severe nasolacrimal duct obstruction using nunchaku-type silicone tubing(N-ST). Cases and Method:This retrospective study was made on 13 cases of nasolacrimal duct obstruction who failed to improve by probing and who were treated by insertion of N-ST during the past 5 years. The series comprised 10 male and 3 female children. The age ranged from 7 months to 10 years,average 37 months. Nasolacrimal duct obstruction was congenital in 9 cases and secondary in 4. Results:N-ST was retained for an average of 2 months. All the cases were free of complications. All the cases showed improved subjective and objective signs of nasolacrimal obstruction including lacrimation,eye discharge,or elevated lacrimal meniscus. Conclusion:Insertion of N-ST is effective for severe nasolacrimal duct obstruction in infants and children.
