What are facial motion disorders?
Also known as: oral movement disorders, facial movement disorders, facial nerve palsy, facial tics.
In order to make facial expressions, (e.g. smiling or closing one's eyes) the brain sends a signal to the muscles of our face through the 7th cranial nerve called the facial nerve. A fairly large number of different conditions affect facial muscle movement which may be absent (paralysis), weak (partial paralysis or paresis) or abnormal (involuntary movements-synkinesis) facial motility.
