title: [Application of MEDPOR surgical implant in the craniofacial reconstruction].
abstract: Since November 1996, 20 cases of craniofacial deformities, either from congenital or traumatic, were treated with MEDPOR surgical implant made from a linear high density polythylene. The animal experiment had shown that the MEDPOR had good organotrophic characteristics allowing tissue ingrowth. The biocompatibility studies in vitro and in vivo had shown that the MEDPOR biomaterial was free from any observable systemic or cytotoxic effect. In the clinical application, it was found that the MEDPOR could be easily modeled and maintained. Because of the ability to induce tissuee ingrowth, the tenacity and stability of the material were enhanced. A total of seven cases of cranial defects, 8 cases of periobital defects or depressed periobital regions, 2 cases of traumatic auricular defects, 2 cases of traumatic saddle nose and 1 case of maldevelopment of mandible angle were treated. All of the cases were followed up for 6 months, the results were satisfactory.
