Swallowing involves a series of psychological, sensory, and motor activities, both voluntary and involuntary. Five cranial nerves (V, VII, IX, X, and XII) are involved in this intricate process. The oropharyngeal phase consists of a voluntary oral stage, mediated by cortex with cranial nerves V, VII, X, and XII, and an involuntary pharyngeal stage, with cranial nerves IX, X, and XII [1]. The present chapter focuses on the dysphagia related to the involvement of these cranial nerves in head and neck and skull base tumors. Swallowing dysfunction associated with stroke and other neurological disorders is not a part of this chapter.
