Bell's Palsy (Facial Palsy)
The facial muscles are controlled by a nerve called the Facial nerve. There are two facial nerves - one for either side.
Dysfunction of one of the nerves causes a facial asymmetry with inability to close the eye fully. Often food, saliva and liquids dribble out from the angle of the mouth in the early stages of the disease.
The diagnosis is quite easy and straight forward. No major tests are required in most cases.
Usually the outcome is very good with most patients showing near total recovery.
