a Preoperative image of the patient 2 (right, patient 4 in Table 1). In the preoperative CT, an arrow shows the affected mandible with a calcifying odontogenic cyst (right). b Free osteo-cutaneous fibula flap harvested from the right lower limb. Osteotomy was performed in two places in the 18 cm long fibula (top). The harvested free osteo-cutaneous fibula flap was transplanted into the mandibular defect using the double barrel method (bottom). c Eleven months after surgery, although the distal part of the osteo flap developed osteonecrosis, there is no tumor recurrence and both functional and esthetical results were fair. This was achieved with a successful implant installation
