Abstract
The use of distraction osteogenesis has gained widespread orthopedic acceptance. This method has recently been applied to craniof acial deformities such as hemifacial microsomia and micrognathia. On the other hand, vascularized bone grafts for mandiblar reconstruction were performed after tumor resection on the patients with oral tumors. However, it is difficult to improve a masticatory function in the cases with severe contracture of intraoral space after surgery, or resection of mandibular condyle. For these cases, distraction osteogenesis and/or transport distraction osteogenesis, a technique used to reconstruct missing bone and soft tissues in segmental deformities, is used. Furthermore, in order to accommodate dentures, alveolar bone augmentation are performed using internal distraction appliance.
In this paper, the procedures of distraction osteogenesis for cases with mandibular bone defects after tumor resection on the patients with oral tumors are reported.
