Palpebral ptosis is defined as the upper eyelid fall. OBJECTIVES: To analyze the results of the surgical correction of palpebral ptosis and to determine its therapeutical effectiveness with various techniques and approach methods. METHODS: A prospective, longitudinal and descriptive study was performed on 32 patients (50 eyes) operated on from ptosis covering May, 2005 through March, 2006. The surgical technique and approach method applied to each case, taking clinical severity into account (slight, moderate and severe), and their effectiveness were evaluated based on postoperative margin-reflex distance reduction in mm. The surgical techniques were reinforcement and reinsertion of aponeurosis, supramaxima, frontalis suspension and posterior approach. RESULTS: Postoperative margin-reflex distance was reduced by 1.2, 2.2 and 3.5 mm in slight, moderate and severe ptosis respectively. CONCLUSIONS: The right selection of the surgical technique and the approach method helps in achieving good results in ptosis correction.
