Nasolacrimal balloon dacryoplasty versus nasolacrimal bi-canalicular intubation for the management of congenital nasolacrimal duct obstruction with a previous failed probing or intubation: a retrospective study
摘要
To compare the results and complications of nasolacrimal duct intubation and balloon dacryoplasty (BDCP) for the treatment of cases with recurrent epiphora following previous probing or intubation.
MethodsA retrospective study including patients with recurrent nasolacrimal duct obstruction following previous probing or intubation whether retreated with balloon dacryoplasty or bi-canalicular intubation. All procedures were performed by the same surgeon. The results were evaluated and compared using a Modified Munk classification.
ResultsThe study included 103 eyes of 77 patients; 53 eyes (51.5%) underwent BDCP and 50 eyes (48.5%) underwent bi-canalicular intubation. Mean age was 4.03 ± 2.71 years (range 9 months to 12 years). Most eyes (85.5%) had severe pre-operative disease (Modified Munk grades 4 and 5). Post-operative, all patients showed improvement in terms of grading according to MMC; the collective success rate of both procedures in both groups was 51.5%, 69.7%, 86.7% and 88.9% at 1 week, 1-, 3- and 6-months post-op. respectively. Subgroup analysis revealed earlier successful outcome in group B compared to group A (p-value = 0.002), yet this relationship is reversed with Group A (BDCP) having 96% success at 6 months follow-up compared to 80% in Group B (Bi-canalicular intubation) (p-value = 0.021). Baseline demographic and clinical characteristics were comparable between the two groups, with no statistically significant differences in age, sex distribution, type of previous intervention (p-value = 0.95), or pre-operative Modified Munk grades. Complications were minimal and insignificant in both groups.
ConclusionBalloon dacryoplasty showed a 96% success rate compared to 80% success rate of intubation after 6 months follow up. Higher success rates of treatment of recurrent CNLDO epiphora is seen when the previous procedure was a simple probing.
