目的先天性颅面畸形经常表现为上颌骨、颧骨、下颌骨、颞骨和软组织的部分发育不良或完全不发育。本研究探索用人工材料(Medpor)代替自体组织移植及寻求简单实用有效的手术操作。方法截骨并以Medpor作为填充材料，进行多部位，大范围组合填充于骨膜下骨与肌肉之间，矫治半侧颅面矮小3 例，单纯性下颌骨发育不良6例。结果外形满意，面部骨轮廓自然，手术创伤小，时间短，一期完成，康复快，术后半年随访充填材料稳定，无不适感。结论⑴ Medpor材料可以大范围、多部位一次组合应用。⑵填充在较深层次（骨与肌肉之间），外形更接近自然骨轮廓形态，如充填于皮下则材料与皮肤粘连形态不佳。⑶结合截骨矫正，可更精确地达到手术所需效果。
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.
