[The application of three dimensional craniomaxillofacial model in the restoration of mandibular bone defects with vascularized fibular autograft].

OBJECTIVE

To evaluate the effect of applying the three dimensional craniomaxillofacial model technique in the restoration of mandibular defects with vascularized fibular autograft.

METHODS

Three dimensional craniomaxillofacial models of 24 patients with mandibular defects were achieved by CT scan and rapid prototype technique. Surgery simulation and individual prefabricated titanium board were designed on the models. Vascularized fibular autograft was obtained, remodeled with titanium implant based upon preoperative surgery simulation, and implanted into the site with mandibular defect.

RESULTS

By using three-dimensional craniomaxillofacial model, all fibular flaps survived without complication in all 24 patients. Bony union was achieved between the implanted fibula and the mandible. First intention of the wound was achieved. The appearance of the mandibular bone was well recovered shown by 3-dimensional CT scan.

CONCLUSION

Based upon the preoperative surgery simulation with three dimensional craniomaxillofacial model, vascularized fibular autograft has many advantages for mandible reconstruction and represents the first choice for the head and neck surgeon.
