Abstract:
Objective To analyse the correlation between tone burst auditory brainstem response (tone burst auditory brainstem response,tb-ABR) and CE-Chirp voice evoked auditory steady-state response (auditory steady-state response,CE-Chirp ASSR) in infants with profound sensorineural hearing loss.Methods A total of 45 infants with profound sensorineural hearing loss underwent threshold tone burst ABR and CE-Chirp ASSR of the frequency response test,response thresholds were recorded in 0.5,1.0,2.0 and 4.0 kHz.Whether there was correlation or not existed between two methods were analyzed,SPSS 11.0 statistics software was used.Results Tone burst ABR and CE-Chirp ASSR could lead to different degrees of threshold in each frequency.Response e elicited threshold percentage mainly concentrated in the 91-100 dBnHL,correlation coefficient between 500-4 000 Hz response threshold elicited rate were:0.837,0.913,0.909,and 0.919,respectively (P ＜ 0.001).The difference of the frequency response threshold test between CE-Chirp ASSR and tone burst ABR were not significant (P ＞ 0.05,Chi square).Conclusions The tone burst ABR and CE-Chirp ASSR each frequency have different levels of residual hearing in infants with profound sensorineural hearing loss diagnosed by Click ABR,good correlation exists between tone burst ABR and CE-Chirp ASSR.
