Purpose: To compare 2 surgical techniques (frontalis flap versus maximal anterior levator resection) as first surgical options for the treatment of congenital ptosis with poor levator function in patients younger than 2 years of age with a follow up of 10 years.
Methods: A retrospective study of 58 patients (71 eyelids) with severe ptosis and poor levator function who underwent frontalis muscle flap (FMF = 47) or maximal anterior levator resection (ALR = 24) for correction of their ptosis. Eyelid measurements were taken at baseline, 1, 5, and 10 years after surgery. The presence of complications, need for reoperations, and palpebral contour were evaluated.
Results: Most patients in both groups required only one surgical procedure with a stable average margin-reflex distance 1 over the 10-year follow-up period in both groups, with no statistically significant difference between the 2 techniques in achieving an adequate palpebral height after one single procedure. Eleven eyelids treated with FMF (23%) and 12 treated with ALR (50%) needed a reoperation, with a statistically significant difference between the 2 techniques. Five ALR patients (21%) and 6 FMF patients (13%) had alterations of eyelid contour. Pop-eyelid and eyelash ptosis were observed in 8% of patients operated with FMF.
Conclusion: Good functional and aesthetic results were obtained with both surgical techniques. FMF required fewer reoperations compared with maximal ALR, offering a better long-term result without residual ptosis.
