Medical Term:

facial paralysis


Definition: paresis or paralysis of the facial muscles, usually unilateral, due to either a lesion involving either the nucleus or the facial nerve peripheral to the nucleus (peripheral facial paralysis) or a supranuclear lesion in the cerebrum or upper brainstem (central facial paralysis); with the latter, facial weakness is usually partial and the upper portion of the face is relatively spared, because of bilateral cortical connections.

Synonym(s): facial palsy, facioplegia, fallopian neuritis
