Title: Clinical investigation of audiologic evaluation in 120 infants and children
Abstract: Objective To explore the clinical application of audiologic evaluation in children who failed the behavioral hearing test,by using the auditory brain stem responses(ABR),transient evoked otoacoustic emission(TEOAE),distortion product otoacoustic emission(DPOAE) and middle ear impedance measure.Methods One hundred and twenty infants and young children who failed the behavioral hearing tests were studied.TEOAE,DPOAE and middle ear impedance measure were used to assess the function of middle-ear.ABR threshold testing stimulated by click was employed to assess high-frequency hearing,and toneburst to low-frequency sensitivity.Diagnosis was made based on these tests.Results From the analysis of ABR,DPOAE,TEOAE,and impedance data,51 cases were found normal in the three tests.There were 64 cases with sensorineural hearing loss,1 case with auditory neuropathy,2 cases with mixed hearing loss and 1 case with conductive hearing loss.Conclusion For infants and young children who failed the behavioral hearing test,it is a good way to adapted ABR and middle ear impedance measure,transient evoked otoacoustic emission(TEOAE),distortion product otoacoustic emission(DPOAE) to estimate their thresholds.
