电生理检测对贝耳麻痹患者的预后评估
AIM:To estimate the prognosis of Bell palsy.METHODS: Blink reflex (BR), electromyography(EMG),motor latency(ML) and amplitude (AMP) of facial nerve were performed in 42 patients with Bell's palsy.The patients were followed about half a year.RESULTS: (1)When 1 of the 3R waves related with the ill side existed or appeared in 3 weeks after onset,97% patients could recover completely.The recovery time was related to the time of the occurrence of R wave.(2) When 1 of the 3 R waves appeared in the 4th week, 60% patients could recover completely.When none of the 3 waves appeared after the 4th week,100% patients could not recover completely.EMG showed spontaneous activities in 3 of the 6 patients in the 4th week.(3) Motor latency and amplitude of facial nerve were examined when the illness stopped developing.All patients had normal latencies.5 patients' amplitudes reduced more than 90% . 3 of the 5 patients did not appear the related R waves after the 4th week.CONCLUSION:BR might provide the early sign of good prognosis of Bell's palsy. BR together with EMG and ML and AMP of facial nerve might provide the later sign of poor prognosis.
