Prognostic value of early electromyography in facial nerve paralysis

85 subjects with serious facial palsy were longitudinally examined to investigate the times and the degrees of their recovery. Electromyographic examination (EMG) was performed between the second and the seventh day from the beginning of the palsy. The precocious EMG shows a very important value in pointing out the degree of lesion in nerve fibres. The seriousness of the nerve damage is strictly correlated with the time and the degree of the recovery so that the EMG proves to be a very important investigation for prognostic purpose
