In several patients with complete facial nerve palsy, it was noticed that when the cheek was stretched there was subsequent spasm of the muscles of facial expression. This also occurred in patients whose facial nerve had been transected.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215111000892_sec2\"><jats:title>Case reports:<\/jats:title><jats:p>We present four patients in whom this response was demonstrated.
