Oral and Maxillofacial tumor leads to severe facial malformation and oral dysfunction such as impairment of mastication, articulation, and deglutition.The main purpose of functional oral and maxillofacial surgery is to restore the facial contour and oral function as much as possible.This presentation discusses the issues of functional reconstruction of maxillary defects after ablative surgery in oral tumor.For maxillary reconstruction, vascularized fibula osteomyocutaneous flap is used in class 2 defect according to Browns classification, vascularized fibula osteomyocutaneous flap and titanium mesh are applied in class 3 defect.Surgical plan and simulative operation of ablative surgery, autologous bone harvest, maxillary reconstruction are all preoperatively made in the computer.According to the result of virtual surgery, the individual replicas of the maxilla and the guide template are made by computer aided manufacturing/computer aided design (CAD/CAM) techniques so that the operation can be performed quickly and accurately.
