title: Endoscopic-assisted retrieval of retained lacrimal stent material in congenital nasolacrimal duct obstruction without dacryocystorhinostomy.
abstract: We report a 3-year-old child with history of congenital nasolacrimal duct obstruction who failed lacrimal probing and underwent bicanalicular intubation. Removal of stent from the superior punctum was unsuccessful and it was trapped in the lacrimal sac. We performed endonasal endoscopic-assisted retrieval of retained stent material without necessitating dacryocystorhinostomy (DCR). There was no recurrence of infection and nasolacrimal duct obstruction symptoms during 6 months of follow-up.
