[Role of nasolacrimal intubation in the treatment of lacrimation caused by congenital lacrimal duct obstruction in infants].

We report a study of a series of 83 cases of congenital nasolacrimal duct obstruction treated with monocanaliculonasal or bicanaliculonasal silicone intubation. Efficacy, complications, as well as the duration of the placement of the probes were studied. The analysis of the various factors of this series (age of the infants at the time of intubation, duration and type of intubation, complications) demonstrated the superiority of short-term monocanaliculonasal intubation (about four weeks) compared to longer intubation.
