Evoked E.M.G. test has been applied in patients with peripheral facial palsy to evaluate the degree of nerve injury.However, prognosis of peripheral facial palsy has not been estimated under a definite criteria based on the results of evoked E.M.G. test. The author reported previously that the number of spikes in evoked wave represented the degree of degeneration of the nerve in more details than the threshold and the latency.The purpose of the present study is to establish a criteria for prognosis of peripheral facial palsy deduced by the results of evoked E.M.G. test. Eighty three patients who were examined in our clinic within one month after the onset of symptom were subjected to this study.The result of evoked E.M.G. test was compared with the degree of recovery of facial palsy in each patient after the laspe more than six months.These results led me to the conclusion that prognosis of peripheral facial palsy should be estimated by the number of spikes in the evoked waves as follows:1) Cases showing spike discharges more than ten recover completely within three months after the onset. Specially, cases under sixty years of age may recover within one month, but cases more than sixty years of age may require more than one month for complete recovery.2) Cases showing nine to six spike discharges may require more than three months after the onset for complete recovery.3) Cases under sixty years of age, showing five to three spike discharges may recovery completely but cases more than sixty years of age recover incompletely.4) Cases showing two to one spike discharges recover incompletely.5) Cases under fifty years of age showing no spike discharge may recover incompletely and in cases more than fifty years of age no improvement may be obtained.
