Polytetrafluoroethylene (PTFE), a nonantigenic, autoclavable, inert, woven synthetic graft material was used to correct ten lower eyelids with retraction secondary to either thyroid disease (7 eyelids) or surgically repaired maxillofacial trauma (3 eyelids). The material was well tolerated for postoperative periods ranging from 10 to 26 months. In two eyelids, a portion of the PTFE was removed to treat eyelid thickening and an infected meibomian gland. Results of histopathologic examination of the graft showed minimal inflammation and capillary and connective ingrowth into the graft matrix as well as a dense fibrous capsule around the graft. In selected cases, PTFE may be an acceptable substitute for other graft materials used in oculoplastic surgery.
