Combined anterior thigh flaps and vascularised fibular graft for reconstruction of massive composite oromandibular defects

Six massive, composite oromandibular defects were reconstructed using combined anterior(anterolateral and anteromedial) thigh flaps and vascularised fibular graft in bridge or chimeric fashion. Except for minor dehiscence in one case infection in another, all flaps survived without complication. Anterior thigh flaps provide large-calibre, long vascular pedicles while derivative branches from the lateral circumflex femoral system facilitiate simultaneous transplantation of multiple components. Because the pecdicle of the vascularised fibular graft is of insufficient length, the lateral circumflex femoral vessels provide a remote vascular source as a flow-through vascular conduit. A combined flap using the lateral circumflex femoral system is considered to be most suitable for reconstruction of through-and-through defects of the head and neck. The authors describe the advantages of this method and detailed anatomy of the cutaneous perforators of the anterior thigh flaps.
