High-density porous polyethylene for facial bone augmentation

Abstract

Medpor is a porous polyethylene biomaterial used in plastic and reconstructive surgery in the craniofacial skeleton. Its porous nature allows for substantial vascular and soft-tissue ingrowth. Medpor is available in a variety of implants including block, sheet, and preformed shapes. In vitro and in vivo studies have demonstrated that Medpor has been successfully used in the reconstruction of the orbital floor and external ear, and in augmentation of the chin, mandibular, nasal, and malar regions.
