✦ Synopsis

Wide exposure of the tumors of the base of the tongue and oropharynx can be easily obtained via mandibulotomy, which provides equally good exposure for tumors of the posterior oral cavity and oropharynx. Segmental mandibulectomy can be avoided in patients where the tumor does not invade the mandible or is not in close proximity of the mandible. Preoperative work-up may include evaluation by means of the fiberoptic telescope to determine the extent of the tumor, examination under anesthesia, panoramic X-ray of the mandible, CT scan and MRI, as well as dental evaluation. Tracheostomy provides airway during the operation and tracheobronchial access for clearance of pulmonary secretions postoperatively. The technique for median labiomandibuloglossotomy is described, as well as the mandibular swing approach and mandibulectomy. Cosmetic deformity after segmental mandibulectomy is minimal but mandible reconstruction should nonetheless be considered based on the extent of the tumor, tumor control, and the need for postoperative radiation therapy.
