Facial Paresis Definition


Facial Paresis:

Severe or complete loss of facial muscle motor function. This condition may result from central or peripheral lesions. Damage to CNS motor pathways from the cerebral cortex to the facial nuclei in the pons leads to facial weakness that generally spares the forehead muscles. FACIAL NERVE DISEASES generally results in generalized hemifacial weakness. NEUROMUSCULAR JUNCTION DISEASES and MUSCULAR DISEASES may also cause facial paralysis or paresis.

Synonym: upper motor neuron facial palsy, peripheral facial paralysis, lower motor neuron facial palsy, hemifacial paralysis, facial paralysis, facial palsy, central facial paralysis.
