Auditory steady-state response and auditory brainstem responses thresholds in neonate and children with moderate to severe and severe to profound sensorineural hearing loss

ASSR is the latest threshold detection technology in pediatric audiology. The aim of this study is to investigate the degree to which ASSR thresholds correlate with click-ABR thresholds. In this cross-sectional study, 32 children ranging in age from birth to 7 years were evaluated by ASSR and ABR in moderate to severe and severe to profound hearing loss groups. The correlation coefficients for frequencies of 500, 1000, 2000, and 4000, mean of 2-4 and mean of 1-4 kHz were between 0.68- 0.90 in moderate to severe hearing loss and 0.79-0.96 in severe to profound hearing loss. Strong correlations were found between ASSR and click-ABR thresholds in all frequencies. This correlation was greater for higher degrees of hearing loss.
