Abstract

Use of alloplastic materials in facial bone reconstruction is still controversial. Medpor porous polyethylene is a relatively new implant material that is well suited for this purpose and has a number of advantages over other alloplasts. It is a pure polyethylene with a unique manufacturing process and pore size. Technically, it is easy to work with; it can be carved, contoured, adapted, and fixated to obtain a precise three-dimensional construct. Physically, it is a pure, biocompatible, strong substance that does not resorb or degenerate. It dem-onstrates long-term stability, high tensile strength, resistance to stress and fatigue, and a virtual lack of surrounding soft-tissue reaction. Rapid tissue ingrowth occurs into the pores. Extensive vascular ingrowth creates the potential to transport cellular products that fight infection deep into the implant. The implant was used in 140 patients from June 1988 to August 1991 to treat acute orbitozygomatic injuries (71), acute Le Fort injuries (24), delayed orbitozygomatic injuries (33), and delayed onlay augmentation (12). In this series, there was 1 instance of implant infection requiring removal, and no implant migration, or exposure.
