Objective:
To explore the application of computed tomographic angiography (CTA) and computer aided design\manufacture (CAD\CAM) techniques in mandible reconstruction with free fibula flap.
Methods:
7 cases of complex mandible defect were reconstructed with free fibula flap. Patients' lower extremity vasculature was evaluated by preoperative CTA examination; mandible tumor resection and reconstruction were simulated by CAD technique, the surgical template was manufactured with CAM technique preoperatively; and fibula flap was shaped according to surgical template during mandible reconstruction operation.
Results:
Preoperative CTA examination performed without complication, the desired anatomy was adequately demonstrated in all patients. All of flaps survived, patients' facial contour are symmetry approximately.
Conclusions:
CTA and CAD\CAM techniques have important value for complex mandible reconstruction in selection of donor site, planning of operation and shaping of fibula flap.
