The blink reflex (BR) has been studied during the first 2 weeks in 122 patients with Bell's palsy and Ramsay Hunt's syndrome. According to early BR (R1), the patients were divided into 3 groups: R1 less than or equal to 13 ms (16 cases); R1 greater than 13 ms (54 cases), and absent BR (52 cases). There was a remarkable tendency towards a satisfactory recovery from paralysis if BR occurred during the first 2 weeks from onset (p less than 0.001). In patients with normal BR, 93.7% had a satisfactory recovery, and in patients with delayed R1, the prognosis was still good: 86.8% had a satisfactory recovery. When the reflex was absent a bad prognosis was given in 55.8% of the patients. The BR and the severity of the lesions according to electroneurograms was tested in 111 patients and found to be significantly correlated (p less than 0.001). BR seems to be a useful index for predicting the prognosis in an early stage of the paralysis, however, more than one test should be performed at the same time to accurately establish the prognosis.
对122例贝尔麻痹和拉姆齐·亨特综合征患者在发病后的前2周内进行了瞬目反射（BR）研究。根据早期BR（R1），将患者分为3组：R1小于或等于13毫秒（16例）；R1大于13毫秒（54例），以及无BR（52例）。如果在发病后的前2周内出现BR，则麻痹恢复良好的趋势显著（p<0.001）。在BR正常的患者中，93.7%恢复良好；在R1延迟的患者中，预后仍然良好：86.8%恢复良好。当反射消失时，55.8%的患者预后不良。对111例患者的BR与根据神经电图判断的病变严重程度进行检测，发现两者显著相关（p<0.001）。BR似乎是预测麻痹早期预后的一个有用指标，然而，应同时进行多项检查以准确判断预后。
