RESUMO

Purpose: to compare the results of levator aponeurosis resection and Muller's muscle-conjunctival resection in the correction of minimal blepharoptosis


Methods: this randomized controlled study was conducted on 20 patients with minimal ptosis [<2 mm and >1 mm] and good levator function [>10 mm] which were assigned to one of two surgical groups: levator aponeurosis resection group or Muller's muscle-conjunctival resection group. Patients were visited on days 1, 3, 7, and 14 and at months 1, 2, 3, and 6, postoperatively to evaluate the symmetry, lid contour, lid crease position, lagophthalmos, lid lag, suture keratopathy, and dry eye


Results: postoperative symmetry was found in 8 cases in both group. Lid crease position symmetry was found in 9 and 5 cases in levator and Muller groups, respectively [P= 0.23 5]. Lid lag was found in 7 cases of levator group [mean= 1.15 mm] and 3 cases of Muller group [mean= 0.5 mm] [P= 0.123]. Mean lagophthalmos was 1.75 mm and 1.15 mm in levator and muller groups, respectively [P= 0.749]. No patient had abnormal contour, suture keratopathy, or dry eye symptoms or signs. Exposure keratopathy occurred in 2 cases of each group


Conclusion: Muller's muscle-conjunctival resection is at least effective as levator aponeurosis resection in correcting minimal blepharoptosis in patients with good levator function and symmetric lid crease
