Benign lesions found in the lower face are odontogenic or non-odontogenic tumors, predominantly ameloblastoma. The management of patients with jaw tumors presents considerable challenges and it is mandatory that an experienced and specialized multidisciplinary head and neck oncology team are involved in all stages of assessment treatment and follow up. The overall aim of treatment is to eliminate the primary tumor and any neck node metastases while minimizing patient morbidity. Although free flap reconstruction now is the preferred method for the vast majority of extensive defects, flap selection is complex. An initial step to reconstruction is to define the defect in terms of bony and soft-tissue components. Adjacent critical structures, such as the eye, nose, and lips, are assessed. A history of radiotherapy or previous neck dissection is noted. The necessary length of the vascular pedicle and donor-site morbidity are assessed. The amount, location, and quality of residual bone, dentition, or denture-bearing alveolar arch largely determine whether a bone-containing flap is necessary.
