Summary The EMG enables diagnosis, follow-up and prognosis of vocal cord palsy as well as an indication for surgery. Using the zoom-endoscope by v. Stuckrad the EMG can be performed in local anesthesia. With a specially designed instrument the needle electrode can be transorally applied exactly in the posterior cricoarytenoid muscle as well as in other muscles of the larynx. As the patient can follow instructions both voluntary and spontaneous activity can be recorded under visual and acoustic control during inspiration, phonation and exspiration on a tape. Thus replay, control examination and electronic summation is possible.
