The effect of a neck dissection on the swallowing function

Abstract

The swallowing function of a patient was observed after neck dissection. If the pharyngeal branch of the vagus nerve is injured the ability to clear the pharynx is reduced. In many cases of oral cancer, reconstruc- tion of the pharynx results in a limitation of laryngeal elevation or a delay of the swallowing reflex, thus causing aspiration. In such cases it is necessary to preserve the pharyngeal branch of the vagus nerve, whenever possible.
