Brief Summary

Mandibular reconstruction is necessary following trauma, tumour resections and extensive infections resulting in severe defects of the mandibular arch. For reconstructing large and recurrent defects, the vascularized free flaps are currently regarded as the gold standard. The use of these flaps, however, presents several major inconveniences. Although regenerative medicine in the field of cranio-maxillofacial reconstruction has now become a common practice, the main technical challenge is still related to vascularization of the regenerated tissue in large defects. Axial vascularization of constructs using a microvascular arteriovenous fistula/loop (AV loop) aims at providing the construct with blood supply through a defined and dedicated vascular axis. This technique was successfully demonstrated in some case reports, but was never applied in the craniofacial region. The current study aims to apply and assess the technique of axial vascularization using the AV loop of a bone substitute to reconstruct mandibular defects.
