[Chronic dacryocystitis cured by probing of the duct].

A seven-year-old case with chronic dacryocystitis resulting from congenital obstruction of the nasolacrimal duct was cured not by a dacryocystorhinostomy but by probing of the duct. Our results show that even in case of planned dacryocystorhinostomy, probing of the duct should be performed at least once.
