Clinical experience with auditory brainstem response audiometry in pediatric assessment

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.
