Auditory brainstem evoked response as a hearing test in infants and children: a follow up study
Insights
The auditory brainstem evoked response (BSER) effectively assesses hearing in children. Click BSER thresholds correlate with audiometric thresholds, and 500 Hz stimuli show promise for low-tone auditory function evaluation.
Area of Science:
- Audiology
- Neuroscience
- Pediatric Medicine
Background:
- Auditory brainstem evoked response (BSER) is a valuable tool for assessing hearing in pediatric populations.
- Accurate hearing assessment is crucial for early intervention and development in infants and children.
Purpose of the Study:
- To evaluate the efficacy of BSER in assessing hearing in pediatric patients.
- To determine the correlation between BSER thresholds and traditional audiometric thresholds.
- To explore the utility of 500 Hz stimuli in BSER for low-tone auditory assessment.
Main Methods:
- Review of BSER data from 293 infants and children under 11 years old.
- Correlation analysis between click BSER thresholds and average audiometric thresholds (2-4 kHz range).
- Preliminary assessment of 500 Hz stimuli for low-tone auditory function evaluation.
Main Results:
- BSER thresholds for click stimuli showed a strong correlation with average audiometric thresholds in the 2-4 kHz range.
- Preliminary findings suggest 500 Hz stimuli may effectively assess low-tone auditory function.
- The study highlights the need to consider factors like otitis media and CNS pathology when interpreting BSER results.
Conclusions:
- BSER is a reliable method for hearing assessment in uncooperative pediatric subjects.
- Click BSER thresholds provide valuable information about high-frequency hearing.
- Further research into 500 Hz stimuli is warranted for comprehensive low-tone hearing assessment.
Abstract:
In recent years the auditory brainstem evoked response (BSER) has become an established aid in assessing hearing in unco-operative subjects. We have reviewed our experience with this technique in 293 infants and children aged less than 11 years. We have found that the threshold for click BSER correlates well with the average audiometric threshold in the 2-4 kHz range. We have had encouraging preliminary experience to support the claim by other workers that 500 Hz stimuli may be used to assess low tone auditory function. In interpreting results it is important to appreciate that hearing levels may fluctuate with disorders such as otitis media and occasionally in cases of meningitis. Caution is also advised in interpreting results in cases where central nervous system pathology capable of affecting auditory pathways is known to exist.
