Free fibula flap is the most common free tissue transfer for maxillary and mandibular reconstructions. The distal part of the harvested bone is transferred, while the proximal part is removed by sub-periosteum dissection. The vascularized periosteum attached to the vascular pedicle has osteogenic potential. 61 patients reconstructed with free fibula flaps were divided in 2 groups: 41 flaps performed with a standard technique and 20 flaps performed by dissecting the periosteum from the pedicle. Patients were followed up with orthopantomography and CT scan at 6, 12, 18 and 24 months after surgery. The minimum follow-up time was 18 months. With retrospective analysis of the first group we diagnosed 7 pedicle ossifications on 41 reconstructions (17%). In the second group, no pedicle ossification was observed (p < 0.05). The dissection of periosteum from the vascular pedicle of free fibula flaps avoids the risk of ossification.

Abstract
Free fibula flap is the most common free tissue transfer for maxillary and mandibular reconstructions. The distal part of the harvested bone is transferred, while the proximal part is removed by sub-periosteum dissection. The vascularized periosteum attached to the vascular pedicle has osteogenic potential. 61 patients reconstructed with free fibula flaps were divided in 2 groups: 41 flaps performed with a standard technique and 20 flaps performed by dissecting the periosteum from the pedicle. Patients were followed up with orthopantomography and CT scan at 6, 12, 18 and 24 months after surgery. The minimum follow-up time was 18 months. With retrospective analysis of the first group we diagnosed 7 pedicle ossifications on 41 reconstructions (17%). In the second group, no pedicle ossification was observed (p < 0.05). The dissection of periosteum from the vascular pedicle of free fibula flaps avoids the risk of ossification.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
