先天畸形、创伤、炎症和肿瘤等所致的下颌骨缺损重建在临床上仍是一个难题。单纯游离骨移植在肿瘤放疗患者受区条件差的情况下有较大的局限性,血管化游离骨移植也会造成其供区创伤和继发畸形。近来,异位预成血管化骨移植为下颌骨缺损重建提供了新的途径。下面就血管化骨异位预成的方法、所需条件、优点及其研究进展作一综述。
Congenital malformations, trauma, inflammation and cancer caused by mandibular defect reconstruction in clinical is still a problem. Pure free bone transplantation in patients with tumor radiotherapy in poor conditions under the conditions of greater limitations, vascularized free bone graft can cause its donor area trauma and secondary deformity. Recently, ectopic pre-vascularized bone graft has provided a new approach for the reconstruction of mandibular defects. The following vascularized bone ectopic preformed method, the required conditions, advantages and research progress are reviewed.
