Seven patients with postfacial palsy contracture and mass contractions were investigated electrophysiologically. In 3 patients the early blink reflex showed an unusually high amplitude, which can be attributed to enhanced excitability of facial motor neurons. In 5 patients the early blink reflex had acquired a crossed character. It is assumed that changes in organization of the facial nucleus contribute to the altered function of reinnervated facial muscles.
