Reconstruction of mandible with fibula free flap.

Abstract

The fibula can be used as a donor for a free flap for mandible reconstruction. It has the advantages of low donor site morbidity, consistent shape, ample length, and distant location to enable a two-team approach, allowing multiple osteotomies because of its periosteal circulation. It can be raised with a skin island for composite tissue reconstruction. Eight segmental mandibular defects (average 11.62 cm) were reconstructed following resection for tumour. Six defects consisted of bone alone and the other two had only a small amount of associated intraoral soft-tissue loss. Two patients underwent primary reconstruction. We performed two or three osteotomies on each graft and used miniplates and wires for bone fixation. The flaps survived in all patients. All osteotomy sites healed primarily. The aesthetic result of reconstruction was satisfactory.
