Function and appearance following surgery for intraoral cancer.

Operations for intraoral carcinoma do produce deformities and loss of function. Historically, surgeons have constantly tried to correct or improve these deficiencies. The tendency on the part of the surgeon is to replace each bit of tissue removed, hoping that if the site appears normal the patient will be normal. The appearance of the patient has as a rule been given more attention than the functional result. Dysfunction is related to the alteration of certain anatomic and physiologic conditions identified as: (1) inability to obliterate the anterior oral cavity, (2) defects in the palate, (3) inability to close off the oropharyngeal space, and (4) disturbance of normal channels to bypass the larynx. Lateral mandibulectomy and radical neck dissection performed for cancer of the retromolar area, lower gum, lateral tongue, or floor of the mouth will in most instances result in very acceptable cosmetic and functional results. These patients look well, speak well, eat and swallow well, and can assume their usual role in society. Further surgical attempts to improve any deficiencies are discouraged. Patients sometimes ask about bone grafting or devices to replace the resected mandible and our recommendations are very emphatic on the negative side.
