[Prognostic value of blink reflex in patients with Bell's palsy].
Blink reflex(BR) and electroneurography (ENoG) were carried out in 31 healthy people to obtain normal value. The manifestations of nerve excitability test(NET), ENoG and BR of 60 patients with Bell's palsy within 3 weeks of onset were studied. The results indicated that when the appearance of BR was regarded as good prognosis, facial paralysis recovered completely, the rate of accuracy of predicting facial paralysis was 100%, when the disappearance of BR was regarded as bad prognosis, it isn't a useful test for evaluating prognosis of facial paralysis within the first week of onset (for very few cases tested with NET and ENoG), and less useful than ENoG and NET within the second week and similar to ENoG and NET within the third week of onset.
