[Results of endonasal intubation of the nasolacrimal duct in children with congenital dacryocystitis].

Results of endonasal catheterization of the naso-lacrimal canal of 74 children with congenital dacryocystitis (bilateral problem in 10 of them) are presented. Prior to this manipulation, the patients were exposed to contrast X-ray study of the lacrimal sac for diagnostic purposes. Retrograde catheterization as a method for treating congenital dacryocystitis was very good in 97.3% children of up to 2 years old, 50% children of up to 3 years old, and 33.3% children between 3-4 years old. The patency of the naso-lacrimal canal also recovered in an 8-year-old child. All this gives evidence that, irrespective of children's age, retrograde catheterization should be applied to treat congenital dacryocystitis. After the patency of the naso-lacrimal canal was restored, the external fistula of the lacrimal sac was cauterized with 7% solution of trichloroacetic acid.
