Insights
Probing for congenital nasolacrimal duct obstruction is successful regardless of sex or age over six months. However, nasal alterations like rhinitis can decrease success rates.
Area of Science:
- Ophthalmology
- Pediatric Surgery
Context:
- Congenital nasolacrimal duct obstruction (CNLDO) is a common condition in infants.
- Nasolacrimal probing is a primary surgical intervention for CNLDO.
Purpose:
- To evaluate the success rate of nasolacrimal probing in children with CNLDO.
- To identify factors associated with probe failure in this population.
Summary:
- A retrospective study of 80 children undergoing nasolacrimal probing for CNLDO found no significant difference in cure rates based on sex or age (even over 12 months).
- Nasal conditions such as rhinitis, mucosal hypertrophy, turbinate bone hypertrophy, septal deviation, and sinusitis were identified as factors associated with probe failure.
Impact:
- Findings suggest that age and sex are not significant predictors of probing success for CNLDO.
- The study highlights the potential impact of concurrent nasal pathologies on the outcomes of nasolacrimal probing, guiding clinical management.
Purpose:
To determine the success rate of probing for congenital nasolacrimal duct obstruction and the factors related to probe failure.
Method:
A retrospective observational study was conducted, involving 80 children with congenital nasolacrimal obstruction who underwent nasolacrimal probing. The subjects were evaluated according to sex, age and probing outcome. The data were evaluated according to the descriptive method, Goodman test and Mann-Whitney test adopting a significance of 5%.
Results:
The possibility of cure was the same in both sexes. The mean age at cure was 19.95+/-11.44 months and on failure was 23.67+/-15.21 months. The analysis showed no significant change in cure rate when over 6 months old. Nasal alterations such as rhinitis, mucosal or turbinate bone hypertrophy, septum deviation and sinusitis were associated with probe failure.
Conclusion:
The cure rate does not vary significantly at intervals of increasing ages even it over 12 months old. Nasal alterations might be included in the causes of failure.
