[Transformation techniques for the fibula of the mandible].

Free flaps from the fibula to rebuild the mandible have allowed for improved results in the reconstruction of this bone. We propose a new and more precise technique to further enhance the functional and esthetic reconstructive result. We base the planning for the free flap on specific measurements obtained on the cephalometric analysis. Preoperative angular determinations allow for more precise fibula osteotomies prior to transection of the donor vessels.
