PURPOSE: We report our 11-year experience with a new technique to prefabricate the osteocutaneous free fibula flap to reconstruct defects of the maxilla and mandible not amenable to conventional methods of treatment. MATERIAL AND METHODS: We treated 11 patients aged 17 to 47 years with jaw defects using prefabricated free fibula grafts from 1994 to 2005. We prepared the fibula on the leg with a 6- to 8-mm muscle cuff; next we transferred the bone flap to the surface of the leg without severing the pedicle, and then covered the muscle almost circumferentially by partial thickness skin graft. The bone flap was left in place with its pedicle intact for 2 to 3 months, after which the skin graft had taken and the flap was free of inflammation. The fibula flap was then transferred to the face, fixed in place with plates, and microvascular anastomosis was performed. Implant placement was completed 4 to 6 months after transfer of the flap to the oral cavity. RESULTS: Graft take was unremarkable in all cases. There were no cases of infection and only minor complications. Edema of the flap may be encountered, which subsides with time. If the mandible is not edentulous the mandibular teeth may bite into the flap, but these wounds heal by the time the patient is ready for implant insertion (3 to 6 months). Implants placed in the fibula were successful during the follow-up period (2 to 13 years). CONCLUSION: The prefabricated fibula with a "banking time" on the leg for flap maturation seems to be a better choice compared with other methods of using the fibula for reconstruction and has passed the test of time. We hereby report this new technique to add to the armamentarium of jaw reconstruction surgery.
