Intraoral Approach and Stereolithographic-guided Large Mandibular Reconstruction with Fibula Free Flap.

SUMMARY: The reconstruction of mandibular defects has always been of great concern, and it still represents a challenge for head-and-neck reconstructive surgeons. The mandible plays a major role in mastication, articulation, swallowing, respiration, and facial contour. Thus, when undertaking mandibular reconstruction, restoration of both function and cosmetics should be considered as the measure of success. Microsurgical reconstruction is the gold-standard method to repair a segmental mandibular defect. Reconstruction of sizeable defects often needs a large neck incision, leading to unsatisfactory cosmetic outcomes. Virtual surgical planning and stereolithographic modeling are new techniques that offer excellent results and can provide precise data for mandibular reconstruction and improve postoperative outcomes. We present a case of complete intraoral resection and reconstruction of a large ameloblastoma of the mandible.
