Symphysis and skin

The mandibular defect will involve the majority of the symphysis and may extend to the subcondylar region of the more involved side and as far posteriorly as the mandibular angle of the less involved side. There should be adequate condylar bone on the more involved side to allow the placement of at least two screws in the bone plate. Such a defect is usually accompanied by mucosal defects extending from the floor of mouth into the retromolar trigone, with possible extension into the anterior/lateral tongue.

This defect typically results from resection of squamous cell carcinoma, sarcomas or osteoradionecrosis.
