Clinical experience with auditory brainstem response audiometry in pediatric assessment
Insights
Auditory brainstem response audiometry effectively evaluated pediatric hearing sensitivity, even with central nervous system involvement. This technique provided valuable peripheral auditory data, showing good agreement with other audiometric methods.
Area of Science:
- Pediatric Audiology
- Neuroscience
Background:
- Auditory brainstem response (ABR) audiometry is a key diagnostic tool.
- Evaluating auditory function in children presents unique challenges.
Purpose of the Study:
- To review the experience of using auditory brainstem response (ABR) audiometry for evaluating 167 children.
- To summarize referral sources, sedation practices, and interpretation of ABR results.
Main Methods:
- Retrospective review of 167 pediatric cases undergoing ABR audiometry.
- Analysis of sedation requirements and factors influencing ABR interpretation.
- Comparison of ABR findings with behavioral and impedance audiometry.
Main Results:
- Sedation was necessary for 136 children.
- Central nervous system involvement occasionally made ABR results ambiguous.
- ABR provided crucial information on peripheral auditory sensitivity.
- Good agreement was observed between ABR, behavioral, and impedance audiometry predictions.
Conclusions:
- Auditory brainstem response audiometry is a valuable technique for assessing peripheral auditory sensitivity in children.
- Despite potential ambiguities from central nervous system conditions, ABR offers unique diagnostic insights.
- The findings support the utility of ABR in pediatric audiological evaluations.
Abstract:
We discuss our experience with evaluation of 167 children by auditory brainstem response audiometry in 1978. We summarize experience with referral sources, medication for sedation, and interpretation of test outcome. Medication for sedation was required for 136 children. Concommitant central nervous system involvement rendered auditory brainstem response ambiquous in some children; however, the technique still provide useful information about status of peripheral auditory sensitivity obtainable in no other way. Finally, agreement among auditory brainstem response, behavioral, and impedance audiometry predictions was usually quite good.
