Abstract

|
|
Most mandibular reconstructions are performed primarily or secondarily for bony defects caused by injuries or removal of tumors. An autogenous bone graft is still the method of choice for the restoration of mandibular defect. But a conventional autogenous free bone graft does not possess an intact blood supply and is dependent on local nutrition to survive. Severely scarred or radiated tissue are unfavorable beds for bone graft and even more the risk of resorption and infection is increased in these kinds of a poorly vascularized bed.
To overcome this difficulty, free vascularized bone graft has been tried with microsurgical technique. A free vascularized bone graft has significantly higher rate of survival, with less resorption and higher resistance to infection than a conventional free bone graft.
A free vascularized iliac bone graft pedicled on deep circumflex iliac vessels is used widely, as it have many advantages such as, availability of large bloc of composite tissue, simplicity of donor dissection, large and long vascular pedicle and few donor site morbidity.
In this paper, we represent 4 cases of reconstruction of wide mandibular defects using free vascularized iliac bone graft and free osteocutaneous groin flap, and review the characteristics of gunshot wound. The result is satisfactory.
