Balloon Dilatation for Treatment of Congenital Nasolacrimal Duct Obstruction

Abstract

Purpose

To evaluate the safety and effectiveness of balloon dacryocystoplasty in the treatment of congenital nasolacrimal duct obstructions.

Methods

Balloon dacryocystoplasty was attempted in 25 eyes of 21 patients. The procedure was performed successfully in 24 eyes of 20 patients, age range 21–72 months. Nineteen eyes had no previous procedure. The mean age of this group was 43.9 months (range 36–72 months). Five eyes had failed probing of lacrimal system. The mean age of this group was 22.2 months (range 21–24 months). The authors performed balloon dacryocystoplasty under endoscopic guidance. Clinical success was defined as complete remission of epiphora within follow-up period of 7–34 months (mean 25.2 months).

Results

The authors performed balloon dacryocystoplasty in 24 eyes. The first procedure was successful in 20 of them and the clinic success rate was 83.3%. The technique was repeated in the one eye that recurred and as it ended successfully, the clinic success rate increased to 87.5%. In 17 of the 19 eyes (89.4%) in which balloon dacryocystoplasty was performed primarily, and in 4 of 5 eyes (80%) in which balloon dacryocystoplasty was performed secondarily after unsuccessful probing, the procedure was clinically successful. There was intermittent epiphora in 3 eyes (15%) and these were considered as recurrence.

Conclusions

This experience shows that balloon dilatation is a safe and effective treatment of congenital nasolacrimal duct obstruction as a primary procedure in children over 36 months of age and as a secondary procedure after failure of lacrimal system probing. As a result, balloon dacryocystoplasty can be an alternative treatment in older children and can be preferred to silicone intubation and dacryocystorhinostomy performed after unsuccessful probing.
