Facial electromyography in newborn and young infants with congenital facial weakness.

Abstract

Congenital facial weakness involves various clinical manifestations, each of which raises specific problems. The incidence of congenital facial palsies ranges from 1.8 to 7.5‰ of births. Comparison of clinical and neurophysiological data enables aetiologies to be differentiated, pathogenesis to be evaluated, and the prognosis to be assessed.
