摘要
目的 探索分泌性中耳炎(OME)和健康儿童之间中耳共振频率(RF)的差异,以及RF、气骨导差、峰值处鼓室压、峰补偿静态声导纳对儿童OME的诊断效能.方法 2018 年 7 月—2019 年 3 月收治的OME患儿为OME组,同期健康儿童为对照组,均行声导抗测试和纯音测听,记录并对比分析测试结果.结果 OME组的RF为(720.00±353.60)Hz,与对照组的(932.19±318.69)Hz比较差异均具有统计学意义(P＜0.01).OME组的气骨导差、峰补偿静态声导纳、外耳道容积、中耳RF、峰值处鼓室压与对照组相比差异均具有统计学意义,OME组中气骨导差、峰值处鼓室压、峰补偿静态声导纳、中耳RF的受试者操作特征曲线(ROC曲线)的曲线下面积分别为 0.92、0.91、0.69、0.68.结论 OME患儿中耳RF降低,但其诊断效能一般,故RF需与纯音测听、声导抗测试结合,增加OME的检出率.
Abstract
Objective To explore the differences in middle ear resonance frequency(RF)between children with otitis media with effusion(OME)and healthy children,as well as the diagnostic efficacy of RF,air-bone conduction gap,tympanometric peak pressure(TPP),and peak compensated static acoustic admittance(Ytm)for OME in chidren.Methods From July 2018 to March 2019,children diagnosed with OME were selected as the OME group,while healthy children were assigned as the control group.Both groups underwent acoustic conductance resistance tests and pure tone audiometry.The test results were recorded and compared for analysis.Results There was a significant difference in RF between the OME group(720.00±353.60 Hz)and the control group(932.19±318.69 Hz)(P<0.01).The air-bone conduction gap,Ytm,ear canal volume,RF,and TPP in the OME group were all significantly different from those in the control group.The area under the receiver operating characteristic curve(ROC curve)of air-bone conduction gap,TPP,Ytm,and RF in the OME group were 0.92,0.91,0.69,and 0.68 respectively.Conclusions The RF of the middle ear is reduced in children with OME,but its diagnostic efficacy is not optimal.Therefore,the RF should be combined with pure tone audiometry and acoustic conductance resistance test to increase the detection rate of OME.
