摘要
目的:探讨宽频声导抗吸收率在梅尼埃病中的特征。方法:对36例单侧梅尼埃病患者进行宽频声导抗、纯音测听、耳蜗电图和内听道MRI检查,并收集39例正常成年人宽频声导抗结果进行对比。从宽频声导抗数据库中调出鼓室图峰压值对应的各频率吸收率数值,计算吸收率相对面积;计录耳蜗电图中总和电位和动作电位的比值(-SP/AP);鼓室内注射钆造影剂后行内听道核磁共振,判断有无膜迷路积水。使用配对t检验对单侧梅尼埃病患者吸收率面积、吸收率峰值进行比较;使用单因素方差分析对各期患耳吸收率面积、吸收率峰值以及双耳间吸收率面积差值进行比较。结果:单侧梅尼埃病患者双耳间吸收率面积患侧均大于健侧,差异有统计学意义;双耳间吸收率峰值无显著差异;各期梅尼埃病患耳间吸收率峰值、吸收率面积及双耳间吸收率面积差值均无显著差异;正常成年人与单侧梅尼埃病患者双耳吸收率面积差值无显著差异。单侧梅尼埃病患耳内听道钆造影显示内淋巴积水比例为95.24%,耳蜗电图中-SP/AP>0.4为61.11%。结论:单侧梅尼埃病患者宽频声导抗患侧吸收率相对面积大于健侧,敏感性高,但非特异性。
Objective:To study acoustic absorbance characteristics of wideband tympanometry in patients with unilateral Meniere’s disease.Method:Acoustic absorbance were detected using wideband tympanometry in 36 patients with unilateral Meniere’s disease and 39 control subjects excluding inner ear and middle ear disease.All patients with Meniere’s disease underwent electrocochleography,gadolinium contrast internal auditory canal MRI,pure tone test.The integral area formed by the absorbance curve on peak pressure and x-axis(frequency)was calculated.Student’s t-test was used to compare integral areas difference of 2 ears in Meniere’s disease patients and control group.Result:The integral area of absorbance was greater in affected side than unaffected side and there was no difference in peak values of absorbance between 2 ears in Meniere’s disease patients.There was no significant difference in areas between Meniere’s disease in different grade(P>0.05).Peak value of absorbance and difference value of absorbance were not significant between Meniere’s disease patients and normal control.Only61.11% Meniere’s disease patients showed-SP/AP>0.4 and 95.24%showed endolymphatic hydrops in affected side.Conclusion:Affected side in patients with Meniere’s disease showed higher integral area of absorbance than other side,which is high sensitive but not specific.
