Free flaps from the fibula to rebuild the mandible have allowed for im
proved results in the reconstruction of this bone. We propose a new an
d more precise technique to further enhance the functional and estheti
c reconstructive result. We base the planning for the free flap on spe
cific measurements obtained on the cephalometric analysis. Preoperativ
e angular determinations allow for more precise fibula osteotomies pri
or to transection of the donor vessels.
