Balloon catheter dilation for treatment of persistent nasolacrimal duct obstruction¹

Abstract 

PURPOSE: To report the outcome of balloon catheter dilation of the lacrimal duct for treatment of children with persistent nasolacrimal duct obstruction after previous surgery.

DESIGN: Interventional case series.

METHODS: Thirty-two consecutive children with a history of persistent nasolacrimal duct obstruction following previous surgery were treated with nasolacrimal duct probing with balloon catheter dilation of the distal nasolacrimal duct. Patients were excluded from this study if they had a history of facial trauma, systemic disorders that involved the lacrimal system, or nasolacrimal duct cysts. Outcomes were considered excellent if the patient had complete symptomatic resolution of epiphora and dacryocystitis and normal tear drainage on examination, good if the patient had only minimal residual symptoms or a minimally delayed dye disappearance test, fair if the patient had moderate residual symptoms or delayed tear drainage, and poor if there was no improvement.

RESULTS: Thirty-two children (20 with bilateral nasolacrimal duct obstruction and 12 with unilateral nasolacrimal duct obstruction) underwent balloon catheter dilation. Overall results were excellent in 9 (28%) patients, good in 15 (47%) patients, fair in 7 (22%) patients, and poor in 1 (3%) patient. Seven patients had undergone more than one previous procedure. Of these patients, 3 had excellent outcomes, 2 had good outcomes, 1 had a fair outcome, and 1 had a poor outcome following balloon catheter dilation.

CONCLUSIONS: Balloon catheter dilation is a safe and generally effective treatment for children with persistent symptoms of nasolacrimal duct obstruction following previous surgery.
