[Electroneurography of the facial nerve: methods of stimulation and records].
In this study it is, intended to establish the more appropriate points to register the compound action potential from m. frontalis m. orbicularis oculi and nasolabial fold muscles. The optimum site for stimulating electrodes and differences between the first and the last compound action potentials after 20 consecutive stimuli delivered at 1 Hz were analysed.
