description

Impairment of facial motility associated with contralateral hemiparesis is characteristic of pontine lesions. In the Millard-Gubler and Foville syndromes, involvement of the facial nerve is nuclear or infranuclear, resulting in a peripheral-type palsy. Conditions of pontine origin showing hyperactivity of facial muscles are facial myokymia and Brissaud’s syndrome. Brissaud and Sicard [4] reported low-frequency phasic cramplike facial contractions and contralateral hemiparesis in inflammatory brain-stem processes.
