摘　　要：目的　探讨下颌骨缺损血管化腓骨瓣移植术后腓骨高度的变化规律。方法　 32例下颌骨缺损血管化腓骨移植患者均有曲面体层片连续复诊记录 ,用Photoshop软件检测骨高度变化。结果　移植腓骨块与血管蒂不同距离的各位点之间及各解剖部位的腓骨高度变化差异均无显著性。随时间延长 ,腓骨高度逐渐降低 ,术后 12个月时降低 6 6 4 %。结论　腓骨段经 0～ 3处截骨塑形后 ,各骨块改建情况相仿 ,远中骨块血运无受阻迹象。Objective To investigate the changes of vascularized fibular bone height after transplantation for mandibular reconstruction.Methods Thirty-two patients with mandibular defects were reconstructed with vascularized fibular bone. Postoperative follow-up pantomograph was used to evaluate the changes of bone height.Results At different distance from the vessel pedicles, the changes of bone height showed no significant difference. The height of fibular bone decreased gradually with time and reduced by 6 64% at 1 year postoperatively.Conclusions Multiple segmental osteotomies had no effect on blood flow and the different pieces of graft after modeling by osteotomy experienced the similar reconstruction . The volume of grafted fibular bone almost remained stable.
