摘　　要：目的 在齿槽裂手术中,将异种脱细胞真皮基质膜覆盖齿槽裂植骨区,观察新骨形成状况,评价植骨修复效果.方法 选择67例单侧齿槽裂患者,按治疗方法不同分为对照组和试验组.对照组单纯应用髂骨骨松质移植41例,试验组应用异种脱细胞真皮基质膜加髂骨骨松质移植26例.术后1,3,6,12,18,24个月随访,X线片观察齿槽裂植骨区新骨生成情况.结果 对照组病例术后6个月齿槽裂植骨区新骨形成Ⅰ,Ⅱ,Ⅲ,Ⅳ级分别为15,11,9,6例,齿槽裂植骨成活率为84.5％,临床成功率为63.7％.而试验组病例植骨区新骨形成Ⅰ,Ⅱ,Ⅲ,Ⅳ级分别为13,9,3,1例.齿槽裂植骨成活率为97.8％,临床成功率为84.3％.两组植骨成活率、临床成功率比较差异有统计学意义（P＜0.05）.结论 自体髂骨加异种脱细胞真皮基质膜联合应用于齿槽裂植骨术中,可有效提高植骨成功率.Objective To observe the effect of bone repair and evaluate its esthetic outcome with heterogeneous acellular dermal matrix cover the alveolar cleft bone grafting area in the alveolar cleft operation.Methods In 67 cases,unilateral cleft palate,were treated by alveolar cleft conventional surgical method.Cancellous iliac bone grafting were control group,heterogeneous acellular dermal matrix cover the alveolar cleft bone grafting area were treatment group.Radiographs was taken at 1 st,3 rd,6 th,12 th,18 th,24 th month postoperatively to observe the bone regeneration alveolar cleft zone.Results The alveolar cleft graft area new bone formation with Ⅰ,Ⅱ,Ⅲ,Ⅳ grade after 6 months in control group was 15,11,9,6 cases and in treatment group was 13,9,3,1 case.The graft survival rate and success rate （97.8%,84.3%） of treatment group were higher than that of control group （84.5%,63.7%）,the difference was statistically significant （P 〈 0.05）.Conclusion The successful rate of operation could be warranted,by the joint application of autogenous iliac bone grafts and heterogeneous acellular dermal matrix in the alveolar cleft operation.
