Abstract
• The records of patients undergoing transmandibular approaches to soft-tissue carcinoma of the oral cavity and oropharynx were reviewed retrospectively. Thirty-nine patients requiring lateral segmental hemimandibulectomy and 45 patients requiring a mandibulotomy were identified. None of the patients given mandibulectomy underwent bone reconstruction, while all of the patients with mandibulotomy had repair at the completion of the case. A total of 53 patients were available for recall and functional assessment. Patients with mandibulotomy did not experience significant dysfunction of the temporomandibular joint. Patients with mandibulectomy demonstrated increasing amounts of eccentric occlusion; however, this did not affect diet and was not reported to be uncomfortable by these patients. When feasible, preservation of the mandible yielded an improved aesthetic result; however, functional results in patients requiring mandibulectomy compare favorably with those obtained after mandibulotomy and repair.
