Outcomes of Anterior Levator Resection and Frontalis Sling in Congenital Ptosis with Poor Levator Function

Purpose: To compare anterior levator resection with frontalis sling in congenital ptosis with poor levator function. Methods: We performed a retrospective review of 19 patients (25 eyes) undergoing anterior levator resection and 25 patients (28 eyes) undergoing frontalis sling for congenital ptosis with poor levator action of 5 mm or less from January 1995 to December 2001. Results: The mean postoperative MRD1 were 2.4±0.95 mm in the anterior levator resection group and, 2.6±0.94 mm in the frontalis sling group. Surgical outcomes were good, fair and poor in 11, 10, and 4 eyes of the anterior levator resection group and in 14, 9, and 5 eyes of the frontalis sling group, respectively. Success rates were 84.0% and 82.1% in each group. There were no statistically significant differences between the two groups (P>0.05). Conclusions: In congenital ptosis with poor levator function, the surgical outcomes of anterior levator resection were as good as those of frontalis sling.
