Purpose
This study compares the success rates of anterior (AA) and posterior (PA) approaches to congenital ptosis repair in children and examines how levator function (LF) influences the selection of surgical approach.
Methods
We conducted a retrospective cohort study at a UK tertiary hospital, including pediatric patients who underwent AA or PA for ptosis repair between 2014 and 2023.
Results
A total of 74 eyes undergoing congenital ptosis correction were identified. Exclusions included 7 cases of Marcus Gunn syndrome, 1 case of Microphthalmia, and 25 cases with incomplete data or lost to follow-up. This left 41 patients (22 AA, 19 PA) with a mean age of 8.15 years and a mean follow-up of 8 months. The mean MRD1 at final follow-up was 2.56mm for AA and 3.18mm for PA. A successful outcome (MRD1 2-4.5mm) was achieved in 31 patients (15 AA, 16 PA). Statistical analysis revealed no significant difference between the two approaches (p=0.187). Revision rates also showed no significant difference (p=0.091). Among patients with LF >10, PA had a higher success rate (90.9%) compared to those with LF ≤10 (75%), though this difference was not statistically significant (p=0.763).
Conclusion
Both the anterior and posterior approaches to congenital ptosis repair demonstrated high success rates, with no significant difference in outcomes. Levator function may assist in approach selection; however, further research with a larger sample size is needed to confirm its impact.
