Purpose: The aim of this study was to compare the results of three materials used for frontal muscle suspension in the treatment of palpebral ptosis. Methods: Sixty-six eyes in 46 patients with palpebral ptosis were operated with a modified Fox technique. The suspension was performed with autologous fascia lata in 18 cases (group 1), criopreserved fascia lata in 23 cases (group 2), silicone in 15 cases (group 3), and PTFE in 20 cases (group 4). The results were evaluated according to the height symmetry of the palpebral opening and the improvement in visual capacity. Results: The results were considered satisfactory in 16 patients (88%) in group 1, 19 cases (82%) in group 2, 12 cases (80%) in group 3, and 18 cases (90%) in group 4. Complications included the loss of correction with recurrent palpebral ptosis requiring revision surgery, or foreign body granuloma formation. The highest complication rate occurred in group 4 (40%), and the lowest in group 1 (5%). Two thirds of the patients with recurrent ptosis were included in the group of younger patients. Conclusions: Autologous or homologous fascia lata is superior to silicone or PTFE when used as a suspension material in the treatment of palpebral ptosis.
