Facial nerve function was evaluated with permanently implanted electrodes for registration of electroneurography in an experimental model. The test-retest reproducibility was analyzed under normal conditions, as well as after facial nerve section. The mean observed intraindividual variation obtained at different sessions was 4%. We believe that the method is well suited for studies of experimental facial palsy.
