The information that pass through the facial nerve allows the expression of our smile, joy or sadness, the “facial expression”. The face is the mark of our individuality. The facial nerve is responsible for innervation of the face muscles, like the previous two-thirds of the tongue and secretion of salivary and tears glands. The aim of this work is to remember the anatomy and physiology of the facial nerve, pathology and possible treatments of facial paralysis.
