Marginal resection of the mandible in the management of squamous cancer of the floor of the mouth.

Abstract Over a fifteen year period, marginal resection of the mandible was used as all or part of the initial treatment of twenty-three selected patients with squamous cancer of the floor of the mouth. All patients were classified as T 1 or T 2 on the basis of the extent of the primary tumor. The lesions were lying in the gingivolingual gutter close to the lingual surface of the mandible. Local control rates were obtained that were comparable to the local control rates obtained with other surgical procedures including wider bone excision and with irradiation for patients of the same T classification.
