Anatomical basis for transplantation of microsurgical anastomosed autologous and allogenic bone transplantants for reconstruction of the mandible in animal experiments (Göttingen-Minipig).

Abstract

The possibilities of extraction and transplantation of bone with microsurgical vascular anastomosis for reconstruction of mandibular defects were to be examined in animal experiments. On the basis of the arterial vascularization of the ossa coxae of the Göttingen minipig which has been demonstrated, the cranioventral region of the os ilium is especially suitable as transplant. The separate vascularization of this bone area allows the extraction of a bone block with a sufficiently long afferent vascular stump. The experimental operations performed in the meantime display an excellent rate of healing of the microsurgically anastomosed bone transplants in the mandible.
