[Assessment of reinnervation of the muscles of facial expression following plastic repair of the facial nerve with the descending branch of the hypoglossal nerve (according to electromyographic findings)].
The data of electromyographic studies of the bioelectrical activity of the facial muscles following plastic repair of the facial nerve with the aid of the descending branch of the hypoglossal nerve permit to interpret the succession and quality of the reinnervation of the muscles. Myoelectrogenesis, as shown by the examinations of 13 patients, develops earlier and with greater completeness in the muscles around the mouth than in the orbicular eye muscle and the frontal muscle, which corresponds to the clinical observations. In the process of reinnervation the activity of the zygomaticus muscle favoured the formation of joint and voluntary movements of the orbicular muscle of the eye and of the frontal muscle.
