摘　　要：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 42p atients with Bell’ s pal-sy.The patients were followed about half a year.RESULTS:(1)When 1of the 3R waves related with the ill side existed or appeared in 3weeks after onset,97%patients could reco ver completely.The recovery time wa s related to the time of the occurrence of R wave.(2)When 1of the 3R waves appeared in the 4th week,60%patients could recover complete-ly.When none of the 3waves appeared a fter the 4th week,100%patients could not recover completely.EMG sh owed spontaneous activities in 3of the 6patients in the 4th week.(3)Motor latency and amplitude of facia l nerve were examined when the illness stopped developing.All patients had normal latencies.5patients’ amplitudes reduced more than 90%.3o f the5patients 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 an d AMP of facial nerve might provide the later sign of poor p rognosis.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 42p atients with Bell' s pal-sy.The patients were followed about half a year.RESULTS:(1)When 1of the 3R waves related with the ill side existed or appeared in 3weeks after onset,97%patients could reco ver completely.The recovery time wa s related to the time of the occurrence of R wave.(2)When 1of the 3R waves appeared in the 4th week,60%patients could recover complete-ly.When none of the 3waves appeared a fter the 4th week,100%patients could not recover completely.EMG sh owed spontaneous activities in 3of the 6patients in the 4th week.(3)Motor latency and amplitude of facia l nerve were examined when the illness stopped developing.All patients had normal latencies.5patients' amplitudes reduced more than 90%.3o f the5patients 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 an d AMP of facial nerve might provide the later sign of poor p rognosis.
