AIM:To compare the functional and cosmetic effects of two different surgical techniques for congenital ptosis.

METHODS: The patients were divided into four groups according to the operation method: Patients undertook bilateral fascial suspension surgery as Group A(42 eyes of 21 cases); Patients undertook bilateral levator muscle shortening surgery as Group B(38 eyes of 19 cases); Patients undertook unilateral fascial suspension surgery as Group C(24 eyes of 24 cases); Patients undertook unilateral levator muscle shortening surgery as Group D(29 eyes of 29 cases). Each group patients were followed for postoperative function and appearance effect.

RESULTS: 1)Early postoperative of two operation function success rate was up to 100%, the function of levator muscle shortening surgery was 97.01% in the late postoperative, was higher than bilateral fascial suspension surgery(87.88%), with statistical difference in both surgerys(P<0.05). 2)Appearance effect of two kinds of operation method in early postoperative had no statistical difference(P >0.05); In the late postoperative, the mean grades for “Lid Contour” and “Lid Crease” of Group B were better than that of Group A(P<0.01). While the mean grades for “Lid Contour”, “Symmetry of Lid Height” and “Lid Crease” of Group D were similarly better than that of Group C(P<0.01).

CONCLUSION: Two kinds of operation method have good effects on the treatment of congenital ptosis. In terms of cosmetic effect, levator muscle shortening surgery is better.
