The clinical significance of analysis of frequency domain of transient evoked otoacoustic emissions

ZHONG Nai chuan 1 ( 1 Department of Otolaryngology,Union Hospital,Tongji Medical University,Wuhan 430022)  
Objective:To determine the clinical value of analysis of frequency domain of transient evoked otoacoustic emissions (TEOAE).Method:Frequency domain of TEOAE were measured in ①normal functional ears;②noise exposure ears;③Meniere′s ears;④pathologic ears of media ear;⑤contralateral suppression of normal ears.Result:①After exposure to noise,the value of band signal/noise ratio were decreased in certain frequconcy band,main frequency of FFT response were changed in frequency spectrum.②In the ears of Meniere′s disease,after the administraton of glycerol,the value of band signal/noise ratio were increasd in certain frequency band,no TEOAE were elicited before the adminitration of glycerol,but they appeared after glycerol administraction in some ears ,main frequency were changd in frequency spectrum,③In the pathologic ears of media ears.The value of band signal/noise ratio decreased to different extent with different kind of patlolggic changes,which is related to the change of acoustic immittance.Besides.Acoustic immittance were normal in those with mild pathologic change in the tympanic menbrane.The value were decreased in band signal/noise ratio.④After contralateral suppression of normal ears,1 kHz and 2 kHz band signal/noise ratio value were decreased.Conclusion:Frequency domain of TEOAE is a sensitive parameter and has property of frequency specificity.It is of great help to study the fanction of outer hair cells farther and make a differential diagnose in the clinial practice.
