Osteotomy and the application of the medpor porous polyethylene flexblock impla nt in the craniofacial surgery

Objective The congenital craniofacial deformities are often manifested as hypoplasia of maxillary, zygomatic, mandibular, temporal and their related soft tissue. This paper is to search for a simple and practical operation by studying the Medpor implantation and observing the postoperative effect. Methods The surgery included both osteotomy and Medpor transplantation as a large scale filling stuff transfer under periosteum for hemi fical microsomia(3 cases) and simple mandibular hypoplasia (6 cases) reconstructi on. Results The result was satisfactory and showed a good nature skeleton facial outline. A half year follow-up visiting showed that the implan ts were stable and there were nouncomfortable feeling. The surgery has the advantates of short operation time, much less surgical trauma, and a quick recovery.Conclusion ⑴The M edpor can be used in large areas and various parts in one operation. ⑵It will be a good facial outline if the transplants are put deep to the muscles, and if put just under the subcutaneous tisse the material will be conglutin ation with superficial skin. ⑶The result will be more precise if the surgery is combined with osteotomy.
