Monocanalicular versus bicanalicular intubation in the treatment of congenital nasolacrimal duct obstruction.

ABSTRACT:

Background

To compare the success rate of monocanalicular intubation (MCI) compared with bicanalicular silicone intubation (BCI) in congenital nasolacrimal duct obstruction (CNLDO) in infants and toddlers.

Methods

In a prospective, nonrandomized, comparative study, MCI (n = 35 eyes) through the inferior canaliculus or BCI (n = 35 eyes) were performed under general anaesthesia in children aged 10 to 36 months with CNLDO. The tubes were removed 3-4 months after tube placement, and the children were followed up for 6 months after the removal of tubes. Therapeutic success was defined as the fluorescein dye disappearance test grade 0-1, corresponding with a complete resolution of previous symptoms. Partial success was defined as improvement with some residual symptoms.

Results

Complete and partial improvement was achieved in 31/35 (88.57%) in the BCI group and 34/35 (97.14%) in the MCI group. The difference between the two groups was not significant (p = 0.584). Complications occurred in both groups. Dislodgement of the tube and premature removal was observed in four BCI cases, and loss of the tube was observed twice in the MCI group. Canalicular slitting was observed in five eyes in the BCI group. Granuloma pyogenicum observed in 2 cases with MCI revealed a few weeks after the tube removal. Corneal erosion in the inferior medial quadrant was observed in one MCI eye and revealed in a few days after the local treatment without tube removal.

Conclusions

Both MCI and the BCI are effective methods for treating CNLDO. MCI has the advantage of a lower incidence of canalicular slit and easy placement.

Project description:Importance:Although the overall rate of spontaneous resolution in congenital nasolacrimal duct obstruction (CNLDO) and efficacy of probing have been documented in the literature, the optimal timing of intervention has not been established. Objective:To report new findings regarding spontaneous resolution in a large cohort of children with CNLDO. Design, Setting, and Participants:The medical records of 1998 consecutive infants diagnosed with CNLDO from January 1, 1995, through December 31, 2004, while residing in Olmsted County, Minnesota, were retrospectively reviewed. Data were analyzed between January 1, 2015, and January 2017. Main Outcomes and Measures:Rate of spontaneous resolution over time and by sex. Results:The cohort, diagnosed at a median age of 1.2 months (interquartile range, 0.4-3.6), was 48% girls (n = 959) and 89% white (n = 1626; 173 were unreported). Among the 1998 cases, 1669 (83.5%) spontaneously resolved, 289 (14.5%) underwent treatment, and the remaining 40 (2.0%) were lost to follow-up. Of the 1958 infants followed up, CNLDO in 925 (47.3%) spontaneously resolved by age 3 months, in 1300 (66.4%) by 6 months, in 1472 (75.7%) by 9 months, and in 1516 (78.4%) by 12 months. The rate of resolution was 35% faster (95% CI, 23%-47%; P?<?.001) at less than 1 month vs 3 months, 43% faster (95% CI, 27%-64%; P?<?.001) at 3 months vs 6 months, 39% faster (95% CI, 16%-64%; P?<?.001) at 6 months vs 9 months, and 1% slower at 9 months vs 12 months (hazard ratio, 0.99; 95% CI, 0.80-1.22; P?=?.78). Congenital nasolacrimal duct obstruction resolved in boys 0.5 months (95% CI, 0.2-0.8; P?<?.001) faster than girls (median, 2.9 vs 3.4 months), and unilateral obstructions resolved 0.2 months (95% CI, 0.1-0.4; P?=?.002) faster than bilateral (median, 3.1 vs 3.3 months) ones. Children probed at 15 months or older had decreased odds of resolution after probing (odds ratio, 0.11; 95% CI, 0.01-0.89; P?=?.04) compared with children probed at age 12 to 14 months. Conclusions and Relevance:Based on this large cohort of children with CNLDO, probing between age 9 and 15 months may be reasonable given that the rate of spontaneous resolution plateaued after 9 months and initial probing success declined after 15 months. This time frame supports both an earlier and narrower range of ages for intervention compared with the current practice of probing after age 1 year.
