Auditory Brainstem Response Latency: Headphone Versus Bone Vibrator Procedures

Comparison of Air conduction (AC) and Bone conduction (BC) auditory brain stem response (ABR) latencies. In this cross-sectional study, 34 (17 males, 17 females) normal-hearing young subjects tested with AC- and BC-ABR. Wave V latencies of both procedures were compared BC- wave V latency significantly prolonged about 0.5 ms. That prolongation was less with decreasing intensity. Female's AC-and BC - ABR latencies were less than males'. AC- and BC- ABR appeared to be useful to determine sensory-neural acuity in children with atresia or difficult to test subjects specially newborns.
