摘　　要：目的：进一步研究眨眼反射（ＢＲ）检查在面瘫诊断中的临床意义。方法：对４０名正常人，不同原因周围性面瘫３０例及腮腺肿瘤３２例进行ＢＲ检查及随访观察。结果：获得ＢＲ潜伏期正常值范围。发现面瘫患者ＢＲ结果与临床面瘫评分有非常显著联系。面瘫早期ＢＲ反应存在者预后良好。Ｂｅｌ麻痹患者在起病２～７２ｈ内ＢＲ检查均出现异常改变。腮腺肿瘤术前ＢＲ异常者均为恶性肿瘤。结论：ＢＲ检查对周围性面瘫程度评估及预后判断有相当意义，对起病７２ｈ内的面瘫诊断优于其它常规面神经电诊断方法，对腮腺肿瘤的良恶性判断有一定参考价值。Objective: To study the clinical value of Blink Reflex (BR) in the diagnosis of facial paralysis. Methods: BR was evoked in 40 normal subjects, 32 cases of parotid tumor and 30 cases of peripheral facial paralysis with other causes. Results: Normal values of BR latencies were obtained and manifestations of BR were obviously correlated to the scores of facial function. The presence of BR response at the early stage of facial paralysis was a good prognostic sign. The BR manifestations in 5 cases of Bells palsy within 72 hours of onset all proved to be abnormal. Four cases of parotid tumor that proved to be malignant by microscope examination had abnormal preoperative BR results. Conclusion: BR seems to be a useful test for evaluating the degree or predicting the prognosis of facial paralysis.BR is superior to other conventional electrophysiological tests in acute facial palsy within 72 hours of onset. BR has a certain degree of referential values in judging the nature of parotid tumor.
