Abstract
Among the alloplastic implants, porous polyethylene (Medpor(R)) is one of the ideal materials for augmentation of the craniofacial region. The interconnecting open pore structure of Medpor(R) allows for tissue ingrowth which promotes host integration and prevents migration. The firm nature allows easy carving and prevents collapsing. Because of these advantages, Medpor(R) has been well used for reconstruction of orbital wall. From March 1994 to December 2002, 27 patients were performed the craniofacial contouring surgery using Medpor(R). Thirteen patients were male, 14 were female. The causes of operations were as follows: trauma, 16; cosmetic, 8; and others, 3. The sites of implant were as follows: frontal, 8; temporoparietal, 6; zygoma, 5; maxilla, 3; mandible, 3; and periorbital, 2. The follow up period was 6 months to 48 months with an average of 12 months. The implants were placed into the subperiosteal plane, and fixed with titanium screws. After fixation, the final contouring was performed by carving with a knife or shaving with a high speed bur. There was no infection. All implants were in place, and there was no extrusion. All patients were satisfied at the results of the operation. The irregular margin of implant was felt in 3 cases. However, reoperation was not performed in these patients because of minimal irregularity. In conclusion, Medpor(R) allows ingrowth of soft tissue without adverse tissue response, and there is no donor mobidity. Implanted Medpor(R) were not absorbed or distorted. With these advantages, Medpor(R) could be one of ideal implants for craniofacial contouring.
