Abstract
Objective To report thresholds and latencies of air and bone conduction clicks-induced auditory brainstem responses in normal infants and to evaluate their values in clinical application. Methods Bone conduction click auditory brainstem responses (BC-ABR) and air conduction click auditory brainstem responses (AC-ABR) were tested in 20 nor-mal-hearing infants (group A:<6 months, group B:≥6months). Data were analyzed with the SPSS 13.0 software. Results Waves of BC-ABRs and AC-ABRs were similar. The mean BC-ABR threshold was 7.50±4.24 dB nHL (95th percentile:15 dB nHL) and the mean wave V latency was 7.45 ± 0.35 ms. There was no significant difference in threshold or latency be-tween the left and right ears, or between males and females. The wave V latencies were 7.48 ± 0.37 ms and 7.42 ± 0.34 ms, and the BC-ABR thresholds were 8.00±4.70 dB nHL and 7.00±3.77 dB nHL for groups A and B, respectively. The AC-ABR/BC-ABR threshold difference was 9.75 ± 4.44 dB and 9.25 ± 2.94 dB for groups A and B, respectively (P>0.05). AC-ABR thresholds were higher than BC-ABR thresholds (9.50±3.72 dB, 95th percentile:15 dB). Conclusion BC-ABR is a valuable and effective tool in newborn hearing screening,assessment and identification of hearing loss.关键词
