【摘要】 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　⑴Medpor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。更多还原

【Abstract】 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 hemifical microsomia(3 cases) and simple mandibular hypoplasia (6 cases) reconstruction. Results The result was satisfactory and showed a good nature skeleton facial outline. A half year follow up visiting showed that the implants were stable and there were no uncomfortable feeling. The surgery has the advantates of short operation time, much less surgical trauma, and a quick recovery. Conclusion ⑴The Medpor 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 conglutination with superficial skin. ⑶The result will be more precise if the surgery is combined with osteotomy.更多还原
