镫骨肌反射试验已广泛用于面神经损害的定位诊断。但有人对其可靠性和作为预后指标的价值尚有怀疑。作者们在近十年内观察了700例以上特发性面瘫患者,去年还对其中一些病人的镫肌反射试验从三个不同的途径进行了研究。一、对120例患者(有糖尿病、妊娠、高血压及对侧镫肌反射消失或听力下降者不包括在内)分别于发病后3～8天内及最后作神经兴奋性试验(NET)和镫肌反射试验。比较患者的年龄,面瘫时间,上述两种试验结果以及面部运动的完全恢复率。结果:在有镫肌反射存在的42例中,92％患者面部运动完全恢复,其平均年龄27岁,平均面瘫持续时间42天,而在78例无镫肌反
Stapedius reflex test has been widely used for the diagnosis of facial nerve damage. However, there are doubts about its reliability and its value as a prognostic indicator. In the last decade, the authors observed more than 700 patients with idiopathic facial paralysis, and in the past year also studied the reflex test of the psoas muscle in some of these patients from three different sources. First, 120 patients (with diabetes, pregnancy, hypertension and contralateral canthal reflex or hearing loss were excluded) were 3 to 8 days after onset and the last for the nerve excitability test (NET) and 镫Muscle reflex test. The patient’s age, facial paralysis time, the above two test results, and the complete recovery rate of facial movement were compared. RESULTS: Of the 42 cases with the presence of the bifidus reflex, 92% of the patients recovered completely with a mean age of 27 years and an average facial paralysis duration of 42 days, whereas in the 78 cases,
