脱矿化骨是一种经盐酸脱矿物质,γ射线照射灭菌,冻干而储存的尸体骨。移植后能诱导间充质细胞转化为成骨细胞而具有骨诱生作用,在29日内可形成新骨,常用做面部缺损的充填和重建。但对其长期效果尚缺乏报告。53例行面部重建术患者接受了75件同种异体脱矿化骨移植物。大部患者为鼻背及鼻小柱整形。移植后随访结果发规,41件较大鼻背移植物,平均随访13个月,平均吸收率为50.7％;有8件
Demineralized bone is a body demineralized by hydrochloric acid, gamma irradiation sterilization, freeze-dried and stored in the body bone. Transplantation can induce mesenchymal cells into osteoblasts with osteoinductive role in the 29 days to form new bone, commonly used for filling and reconstruction of facial defects. However, there is still no report on its long-term effectiveness. Fifty-three patients undergoing facial reconstruction underwent 75 allograft demineralized bone grafts. Most patients with nasal dorsal and nasal column plastic surgery. Follow-up results after transplantation were graded, 41 larger nosocomial transfer, the average follow-up of 13 months, the average absorption rate was 50.7%; 8
