Facial Paralysis

Facial paralysis is defined as an alteration that can affect both the movement and the sensitivity of the face caused by the involvement of the facial nerve (VII cranial nerve). This alteration may occur as a result of neurological damage, after surgery or metabolic problems (among others). Other times there are alterations in facial mobility and sensitivity without an apparent cause justifying them. This type of paralysis is called idiopathic facial paralysis.

The movement limitations of the orofacial muscles make it difficult to articulate speech and handle the bolus during swallowing.
