Abstract: 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.
