Preservation of the mandible in the management of cancer of the oral cavity

Tumors of the oral cavity often involve or are in close proximity to the mandible. Treatment of the tumor will require addressing the mandible. For tumors that are not in proximity to the mandible a mandibulotomy may be required. This procedure will allow for adequate exposure of the tumor. Other tumors that abut or minimally involve the tumor may require removal of a piece of the mandible. When a full segmental resection is not required, a marginal resection can be performed. The techniques described in this article are useful adjuncts in the treatment of patients with head and neck tumors.
