Brainstem Response

Purpose: This article examines whether changes in hearing screening practices are warranted based on the results of the recent series of studies by J. L. Johnson, K. R. White, J. E. Widen, J. S. Gravel, B. R. Vohr, M. James, T. Kennalley, A. B. Maxon, L. Spivak, M. Sullivan-Mahoney, Y. Weirather, and S. Meyer (Johnson, White, Widen, Gravel, James, et al., 2005; Johnson, White, Widen, Gravel, Vohr, et al., 2005; White et al., 2005; Widen et al., 2005) that found a significant number of infants who passed an automated auditory brainstem response (A-ABR) screening after failing an initial otoacoustic emission (OAE) screening later were found to have permanent hearing loss in one or both ears. Method: Similar to the approach used by F. H. Bess and J. Paradise (1994), this article addresses the public health tenets that need to be in place before screening programs, or in this case, a change in screening practice (use of a 2-step screening protocol) can be justified. Results: There are no data to suggest that a 2-step OAE/A-ABR screening protocol should be avoided. Conclusion: Research is needed before any change in public policy and practice surrounding current early hearing detection and intervention programs could be supported.

AbstractObjectiveTo investigate whether oxytocin can prevent ototoxicity related to acoustic trauma.MethodsTwenty-eight rats were divided into four groups: noise (group 1), control (group 2), noise plus oxytocin (group 3), and oxytocin (group 4). Intratympanic oxytocin was administered on days 1, 2, 4, 6, 8 and 10 in groups 3 and 4. Groups 1 and 3 were exposed to acoustic trauma. Distortion product otoacoustic emission and auditory brainstem response testing were performed in all groups.ResultsIn group 1, auditory brainstem response thresholds increased significantly after acoustic trauma. In group 3, auditory brainstem response thresholds increased significantly on day 1 after acoustic trauma, but there were no significant differences between thresholds at baseline and on the 7th and 21st days. In group 1, significant differences were observed between distortion product otoacoustic emission signal-to-noise ratios measured before and on days 1, 7 and 21 after acoustic trauma. In group 3, no significant differences were observed between the distortion product otoacoustic emission signal-to-noise ratios measured before and on days 7 and 21 after acoustic trauma.ConclusionOxytocin had a therapeutic effect on rats exposed to acoustic trauma in this experiment.

Brainstem Response

Purpose: Most newborns are screened for hearing loss, and many hospitals use a 2-stage protocol in which all infants are screened first with otoacoustic emissions (OAEs). In this protocol, no additional testing is done for those passing the OAE screening, but infants failing the OAE are also screened with automated auditory brainstem response (A-ABR). This study evaluated how many infants who failed the OAE and passed the A-ABR had permanent hearing loss (PHL) at 8–12 months of age. Method: A total of 86,634 infants were screened at 7 birthing centers using a 2-stage OAE/A-ABR hearing screening protocol. Of infants who failed the OAE but passed the A-ABR, 1,524 were enrolled in the study. Diagnostic audiologic evaluations were performed on 64% of the enrolled infants (1,432 ears from 973 infants) when they were 8–12 months old. Results: Twenty-one infants (30 ears) who passed the newborn A-ABR hearing screening were identified with PHL when they were 8–12 months old. Most (71%) had mild hearing loss. Conclusions: If all infants were screened for hearing loss using a typical 2-stage OAE/A-ABR protocol, approximately 23% of those with PHL at 8–12 months of age would have passed the A-ABR.
