Purpose: Medpor is white ultra high density porous polyethylene. Its large pore size (125 to 250 µm) is reportedly suitable for bone ingrowth. This biocompatible material has been used successfully during the last decade for various applications in facial skeleton. It is biologically durable, insoluble in tissue fluids and induces no foreign body reaction. The purpose of this article is to present the experience of the Maxillo Facial Division of the Hospital Umberto I Ancona (Italy) in orbital floor reconstruction with this implant. Materials and Methods: Thirty one patients were treated for reconstruction after a big loss of substance of the orbital floor, whit Medpor sheets. Twenty seven were patients whit blowout fracture (11 pure orbital floor fractures and 16 orbitozygomatic fractures). The other cases were submitted to oncologic surgery (emimaxillectomy) for maligant neoplasia of the maxillary sinus or maxillary bone. All the cases treated for trauma repair showed dipolpia and enophtalmos. Results: In all the treated cases, there were no intraoperative complications or implant infections. In two cases, there was no complete remission of the diplopia after six months. In all cases were corrected the enophtalmos. No migrations or extrusion were reported. Conclusions: The study suggests that Medpor sheets implants in orbital floor reconstruction (postraumatic or postoncologic) are safe and with few complications and represent a stable platform for orbital soft tissues. Respect other allpolastic materials, Medpor is more idicated in the largest loss of substance, when there is the need of more support.
