A mandibulectomy is a surgery to remove all or part of your jaw (mandible). You may have a mandibulectomy if you have a tumor involving your jaw. Your jaw may be rebuilt using bone from another part of your body.
It can be cured if found and treated at an early stage (when it's small and has not spread). A healthcare provider or dentist often finds oral cancer in its early stages because the mouth and lips are easy to exam.
