Abstract
PURPOSE
To compare the clinical outcomes of primary nasolacrimal duct probing and primary bicanalicular intubations with endoscopic assistance for congenital nasolacrimal duct obstruction (CNLDO) in children aged 4 to 7 years.
METHODS
Forty-three eyes of 43 children (25 boys and 18 girls) with congenital epiphora who underwent primary unilateral probing and bicanalicular intubation were evaluated retrospectively. The tubes were removed 3 to 4 months after their placement, and the children were followed up for another 6 months after their removal. Treatment success was defined as the normal result of the fluorescein dye disappearance test and complete resolution of the lacrimal symptoms and signs of patients. The success rates were compared between the two groups (bicanalicular intubation vs probing). Type of CNLDO (membranous, incomplete complex, and complete complex) was determined with an endonasal endoscope.
RESULTS
The mean age was 63.3 ± 11.1 months (range: 48 to 84 months) for the probing group and 64.4 ± 12.1 months (range: 48 to 84 months) for the bicanalicular intubation group (P = .915). The bicanalicular intubation group showed significantly greater treatment success (21 of 24, 87.5%) compared to the probing group (11 of 19, 57.9%; P = .038). Bicanalicular intubation provided higher treatment success among patients with complex CNLDO compared to probing (80.0% vs 11.1%, P = .002). There was no difference in mean age between the patients with successful and failed treatment in both groups (P = .631 and .137, respectively).
CONCLUSIONS
Bicanalicular intubation was associated with a higher success rate than probing under nasal endoscopic visualization for the treatment of CNLDO in children aged 4 to 7 years. The type of CNLDO might be the primary factor for the treatment success. [J Pediatr Ophthalmol Strabismus. 20XX;X(X):XX-XX.].
