Int J Audiol:70岁普通人群中听觉功能和耳朵患病率以及听力相关病理研究

2020-03-18 AlexYang MedSci原创

最近,有研究人员基于心理声学和生理测量详细的评估了早期老年的听觉功能情况,并调查了特异听觉和耳科病理的患病率情况。

最近,有研究人员基于心理声学和生理测量详细的评估了早期老年的听觉功能情况,并调查了特异听觉和耳科病理的患病率情况。

研究人员对一个基于老年群体的调查中对未筛选的亚群进行了调查,包括了耳镜;鼓室导抗测试;纯音听力测试;噪声单词识别测试;畸变产物耳声发射和听觉诱发脑干反应。听力学亚型和诊断建立在设定的标准上。单词得分和ABT相关性通过线性回归分析来调查。研究包括了251名年龄为70岁的老年人(113名男性,138名女性,均出生在1944年)。研究发现,传导性病理、耳蜗病理和听觉神经病理的发生率分别占比2%、49%和2%。4%的患者具有不确定的类型。耳蜗功能异常占据大多数,大约20%在言语测试中表现出了比预期更差的表现。噪音言语测试中的不良表现与ABR波I到V的延长的峰间潜伏期间隔相关。

最后,研究人员指出,特殊的耳科病理和听觉病理,而非耳蜗听力损失,在70岁普通人群中是少见的。另外,也有细微的证据表明了听力神经年龄相关的退化。因此,纵向跟踪调查将会很有用处。
