瞬态诱发耳声发射对梅尼埃病的诊断意义

Diagnostic significance of transiently evoked otoacoustic emissions in meniere′s disease

目的:确定瞬态诱发耳声发射(TEOAE)甘油试验对梅尼埃病的诊断意义。方法:对梅尼埃病患者的患耳及健耳(共60耳),以及非梅尼埃病耳(对照耳共8耳)作TEOAE测试。结果:甘油摄入后,患耳TEOAE的波重复性、反应幅值、频带重复性及信噪比值皆比摄入前增加,且甘油试验阳性者纯音听阈高,阴性耳也有显著增加;健耳各参数值也有增加,主频也出现变化。结论:甘油试验TEOAE测试是比纯音听阈测试更为敏感更简便的诊断梅尼埃病的方法。

Objective:To judge the diagnostic significance of TEOAE by glycerol test in Meniere′s disease.Method:TEOAE were recorded from all testing ears with or without Meniere′s disease.Result:The wave reproducibility,amplitude of response,band reproducibility,band SNR in ears of affected ears with meniere′s disease after administration of glycerol were increased,about which the parameters of affected ears in positive glycerol test were obviously higher than that in negative glycerol test.All parameters in normal ears with Meniere′s disease increased too,and there have the changes of main frequency.Conclusion:TEOAE records of glycol test may be more sensitivie and more simple than pure tone audiometry in diagnosing meniere′s disease,and should be used more extensively.
