摘　　要：目的总结应用非血管化髂骨移植同期修复不同类型下颌骨缺损的临床经验。方法对1996年1月～2006年1月136例应用非血管化髂骨移植同期修复下颌骨部份缺损的病例进行回顾性研究,按HCL分类法对下颌骨缺损分类,分析不同类型的下颌骨缺损应用非血管化髂骨移植同期修复术后的效果,植骨区并发症及移植骨吸收情况。结果总体移植骨成活率89.7%,其中L类缺损成功率最高。术后总体感染发生率16.9%,其中H类缺损感染率最高。术后6个月植入骨均有不同程度的吸收,以H类缺损骨吸收最明显。结论非血管化髂骨移植是修复下颌骨节段性缺损的简单有效的方法,以L类缺损最适宜。Objective To evaluate the application of nonvascularized iliac free bone graft in reconstruction of mandibular defects. Methods 136 cases of reconstruction of the mandibular defects with nonvascularized free bone graft between 1996 and 2006 were reviewed, and the post-operative effect, the complications and the absorption of the bone grafts were evaluatedaecording to HCL classification. Results The total successful rate was 89.7 %, and the highest was in L type defect. The total rate of infection was 16.9%, and the highest rate of infection was in H type defect. The absorption of the bone grafts were appeared in all types of defect, but it was more obviously in H type defect. Conclusion It is suggested that nonvascularized iliac grafts is a simple and effective approach for reconstruction of mandlibular defects, especially for L type defects.
