UNILATERAL PARALYSIS of all portions of the facial musculature is a frequent clinical finding. It may occur in a variety of diseases which affect parts of the facial nerve or of its nucleus in the brain stem. However, cases which are apparently idiopathic and which are commonly referred to as "Bell's palsy" are by far the most frequent.
