Features of surgical treatment of nasolacrimal duct stenoses in children
42 children at age from 1 to 15 years (36 - with relapse of congenital nasolacrimal duct (NLD ) stenosis and 6 - with canalicular stenosis) bougienage NLD was done with Ritleng stent intubation. The control group included 25 children 1-5 years old with relapsed congenital stenosis of the NLD, the treatment of which was limited to probing the NLD. In the first group full functional effect was observed in 21 children (58.3 %), in 9 (25.0 %) - was light epiphoria, in 1 (2.8 %) - moderate, and in 5 (13.9 % ) treatment was not effective. In the second group a full functional effect was obtained for each child. In the control group lacrimal drainage was restored fully in 16 (64.0 %) children, in 2 (8.0 %) - moderate and in 7 (28.0 %) - severe epiphora was remained. Using of silicone intubation with the Ritleng lacrimal system allows to continuously retain their foramen in stenotic site without causing an inflammatory response and bedsores lacrimal punctum and canaliculus.
