Value of TEOAE combined with AABR in hearing screening in high-risk newborn

ObjectiveTo explore the value of transient evoked otoacoustic emissions (TEOAE) combined with automatic auditory brainstem response (AABR) in hearing screening in high-risk newborns.

MethodsA total of 140 high-risk newborns with hearing impairment factors were selected and divided into two groups according to whether their two ears passed the TEOAE primary screening.Sixty newborns who failed to pass the primary screening were set as the control group, and 80 newborns who passed the primary screening were set as the observation group.The re-screening was performed at 42 days and 3 months after birth, respectively.The passing rate of newborns in primary screening and re-screening by TEOAE, AABR, and TEOAE combined with AABR were compared between the two groups.

ResultsThe passing rate in the primary screening and re-screening at 42 days and 3 months after birth by TEOAE, AABR, and TEOAE combined with AABR in observation group was significantly higher than that in control group (P < 0.01).The passing rate in the primary screening and re-screening at 42 days after birth by TEOAE and AABR was significantly higher than that by TEOAE combined with AABR (P < 0.01), but there was no significant difference in the passing rate of re-screening at 3 months after birth (P>0.05).

ConclusionsThe combination of TEOAE and AABR has high values in hearing screening in high-risk newborns, which can reduce the incidences of missed diagnosis and false-positive rates, and is worthy of clinical application.
