Abstract:
Objective To explore the use of auditory steady-state response (ASSR) for threshold evaluation in neonates. Methods 30 neonates 60 ears) were included in the study who passed distortion product otoacoustic emission (DPOAE) screening and 45 neonates (78 ears) who failed DPOAE. The ASSR thresholds were evaluated screening, the significant difference was found between the ASSR thresholds at 250 Hz and the ABR thresholds (P ＜0.05), however the ASSR thresholds at 4 000 Hz and average thresholds were not different from the ABR thresholds (P＞0.05). For the neonates whose DPOAE screening results were abnormal, the ASSR thresholds from 250 to 4 000 Hz and average thresholds were not significant different from the ABR thresholds respectively (P＞0.05). olds were not correlated, but there were significant correlations at 2 000 and 4 000 Hz. For the neonates whose DPOAE screening results were abnormal, the ASSR thresholds and the ABR thresholds were significantly correlated at all the carrier frequencies. Conclusion Reliable and frequency specific results could be obtained by ASSR,so it could be a promising audiometry to evaluate the hearing of neonates.
