Medpor implant in cranioorbitomaxillary reconstruction: institutional experience and a review of the literature

Autologous materials remain the gold standard for complex skull base and craniofacial reconstruction, but they carry additional morbidity associated with the second harvest procedure and with prolonged operation time. These autologous materials also resorb in a way that is not predictable, rendering them less ideal in situations where cosmesis and function are of paramount importance to aid with primary healing of the intracranial wound. Medpor porous polyethylene implant is an alloplastic material with unique characteristics that make it an excellent alternative for cranioorbitomaxillary reconstruction. The porous nature of the implant permits the ingrowth of vascularized tissue eventually forming a highly stable complex resistant to infection and deformation. A total of 698 patients undergoing 719 procedures in which Medpor was implanted were reviewed. Two complications occurred that required removal of the implant. On the basis of our results, we believe that the Medpor implant is an excellent alternative to existing alloplastic materials with a low incidence of infection and excellent cosmetic and functional results.
