Int J Pediatr Otorhinolaryngol:听觉神经病谱系障碍儿童患者听力测试结果分析

2019-11-27 AlexYang MedSci原创

听觉神经病谱系障碍(ANSD)是通过听力损失来鉴定的,范围从正常到永久。另外,结果也常被ANSD中听力阈值的波动而变得不准确。因此,有研究人员评估了ANSD儿童听力测定的结果以及年龄和时间对测试结果的影响情况。 研究分析了75名ANSD患者,其中32名(42.7%)为女性。研究发现,双边ANSD和单边ANSD人数分别为55名(73.3%)和20名(26.7%)。研究共评估了130只ANSD耳

听觉神经病谱系障碍(ANSD)是通过听力损失来鉴定的,范围从正常到永久。另外,结果也常被ANSD中听力阈值的波动而变得不准确。因此,有研究人员评估了ANSD儿童听力测定的结果以及年龄和时间对测试结果的影响情况。

研究分析了75名ANSD患者,其中32名(42.7%)为女性。研究发现,双边ANSD和单边ANSD人数分别为55名(73.3%)和20名(26.7%)。研究共评估了130只ANSD耳朵,有80只耳朵符合入选标准。在这些患者中,第一次听力图和最近一次的听力图平均年龄分别为1.94 (0.45-13.68)和4.22 (0.97-14.61)。在ANSD患者中能够从听力图中首次获得语音检测阈值(SDT)和纯音均值(PTA)的平均年龄分别为1.94 (0.50-13.68)和2.86 (0.45-13.68)。SDT/PTA均值在首次听力图和最近一次听力图中分别为47.5/45.7和49.4/53.0?dB。同一个听力图中的SDT和PTA表现出了强烈的相关性(r=0.82, p<0.001)。相似的,起始SDT与后来SDT比较也表现出了强烈的相关性(r=0.73, p<0.001)。另外,SDT和PTA在起始听力图和之后的PTA表现出了较低的相关性,但是仍旧具有统计学显著性(分别为r=0.49, p<0.009和r=0.51, p<0.044)。个体PTA与年龄相关(r=-0.56, p<0.001)。

最后,研究人员指出,在ANSD儿童患者的听力测试中,同一听力图中SDT与PTA,SDT与之后的SDT表现出了强烈的相关性。另外,他们的发现也表明了可靠的SDT和频率特异性信息来计算PTA的听力测试结果通常要到2-3岁才能获得。

听力损失(hearing loss)又称聋度(deafness)或听力级(hearing level)。是人耳在某一频率的听阈比正常听阈高出的分贝数。由于年龄关系产生的听力损失称为老年性耳聋;由于社会环境噪声(年龄、职业性噪声和疾病等影响除外)产生的听力损失称为社会性耳聋;职业性噪声导致的听力损失称为噪声性耳聋。梅斯医学小编整理了近期听力损失的研究进展,与大家一起分享学习!【1】Sci Rep
