Facial paralysis

Involvement of the facial nerve by various disease processes leads to facial paralysis. The causes range from brain tumor, stroke etc.

Sometimes there is no recognizable cause, i.e., it is idiopathic. In that case, the condition is referred to as Bell's Palsy.

The condition affects one half of the facial muscles. The basic pathology of the condition is inflammation of the facial nerve. Although most cases recover spontaneously, some cases might require the help of a facial paralysis surgeon.
