Abstract
Seventy-five eyelids affected by ptosis required a brow muscle suspension, using a new biomaterial, called wide porous expanded polytetrafluoroethylene (ePTFE). The patients, aged between two and 83 years, had a levator palpebrae that could not be 'used' for resection. The results after an average follow-up of 22.6 months were judged to be highly satisfactory as there was no complication caused by the biomaterial.
A histological study using electron and light microscopy enabled the authors to prove complete colonization of the biomaterial by the cells of the organism at the second month after surgery. However, it is too early to conclude definitively regarding the benefits of the biomaterial in ptosis surgery.
