本文介绍了2例用带有血管的游离肋骨移植块整复单侧下颌骨缺损。虽然供给骨髓内血流的主要营养血管并不包括在移植块内(仅利用了骨膜循环),但骨扫描和活体组织检查证实移植块具有活力。切除不包括营养血管的骨移植块不需要在肋椎关节区进行复杂的背部解剖。与普遍骨移植块相比较,带血管的游离骨移植块具有成活力高,愈合较快,骨吸收较少和抗感染力强等优点。(原文共附图9幅)
In this paper, 2 cases of unilateral mandibular defects were reconstructed with free rib graft with blood vessels. Although the main nutrient vessels that supply the bloodstream within the bone marrow are not included in the graft (only the periosteal circulation is utilized), bone scans and biopsies confirmed that the graft was viable. Resecting bone graft blocks that do not include nutrient vessels does not require complex back anatomy in the area of the fossa. Compared with the common bone graft block, the free bone graft with vascular graft has the advantages of high viability, rapid healing, less bone resorption and strong anti-infective ability.
