The significance of primary monocanalicular silicone tube intubation in late surgical treatment in children.

PURPOSE

To evaluate the effect of monocanalicular silicone tube intubation outcomes as an initial surgical treatment in children older than 1 year old with primary nasolacrimal obstruction.

METHODS

Probing or monocanalicular silicone tube intubation was performed as primary surgical treatment on 12-48 months old children with primary nasolacrimal obstruction. Probing was performed on 53 eyes of 43 patients and silicone tube intubation on 45 eyes of 39 patients. Treatment was considered successful after improvement in patient complaints, the presence of normal tear meniscus, and normal results of fluorescein disappearance time test. Retrospective treatment success was compared between two groups according to age groups.

RESULTS

Treatment success was 79.1% in the probing group and 92.3% in the silicone tube intubation group. The success of the treatment was evaluated separately in the groups of 12 to <24 months, 24 to <36 months, and 36 to <48 months, and although the success level of the silicone tube intubation group was consistently found to be higher, the difference was not statistically significant. Treatment success decreased statistically significantly in the probing group with increased age of the patients, especially after 24 months. There was no such statistically significant decrease in the silicone tube intubation group.

CONCLUSION

The choice of monocanalicular silicone tube intubation for primary surgical treatment in children with primary nasolacrimal obstruction provides success without the need for repetitive surgical interventions, especially in children older than 24 months.
