Do polytetrafluoroethylene as a wrapping material for a hydroxyapatite orbital implant? Context: Porous coralline hydroxyapatite orbital implants have been used with great success in anophthalmic sockets. We used a substitute for donor sclera as a wrapping tissue. Orbital implants were wrapped with polytetrafluoroethylene (PTFE) instead of homologous donor tissue in five patients after enucleation. The postoperative course was uneventful in three cases. Complications occurred in two cases: one with implant exposure, and one with severe implant infection leading to its eventual removal.

PTFE is inferior to other wrapping tissue. Final Decision: yes
