Vascularized free flaps are now considered the most appropriate choice for mandible reconstruction because they offer excellent cosmetic and functional results. Various techniques have been proposed. Free fibular flaps have numerous advantages in terms of versatility and contouring. Shaping can be achieved by wedge osteotomy with excellent results. However, this technique leads to bone loss and may be difficult in the later stages of the procedure. The purpose of this report is to describe a simple and safe flap-shaping method involving axial split osteotomy.
