Accurate maintenance of a condyle in a glenoid fossa and keeping the occlusal relationship in patients who have received segmental resection of the mandible is always a difficult task for oral maxillofacial surgeons. A discrepancy in occlusion can cause temporomandibular joint dysfunction, and chronic pain. The most common technique in a mandibulectomy case is pre-bending a reconstruction plate and drilling holes before the mandibular resection so that the original mandibular contour and chin projection can be maintained. Another technique widely used for maintaining occlusion is intermaxillofacial fixation. However, when the mandibular is stricken with a tumor or the patient is edentulous, the aforementioned methods might be unavailable. We present a simple technique by using an AO external skeletal fixation appliance during the operation to stabilize the condyle position and maintain the original occlusion.
