Abstract:
Objective:To investigate the application value of NB CE-Chirp ASSR in the assessment of hearing threshold in children with hearing impairment. Methods:The hearing test results of 44 children with sensorineural hearing loss（88 ears） diagnosed in Shanghai Children's Hospital from January 2023 to December 2023 were retrospectively studied, including 19 ears in mild hearing loss group, 26 ears in moderate group, 20 ears in severe group and 23 ears in extremely severe group. Correlations between auditory brainstem response（ABR） thresholds, pure tone audiometry（PTA） thresholds and NB CE-Chirp ASSR response thresholds in different hearing loss groups were analyzed. Results:The threshold difference between ABR and NB CE-Chirp ASSR（2 000-4 000 Hz） was between 0.50-4.08 dB in different degrees of hearing loss group. There was a significant correlation between NB CE-Chirp ASSR and ABR response threshold in each group（P<0.001）, and the correlation coefficients of mild, severe and extremely severe groups were all greater than 0.8, showing a strong correlation. The average threshold difference between PTA and NB CE-Chirp ASSR in each group was between 1.88-3.91 dB. The correlation coefficients were all greater than 0.8, showing a strong correlation. The difference between PTA and NB CE-Chirp ASSR response threshold at 500, 1 000, 2 000 and 4 000 Hz in each groupwas between 0.25-3.84 dB. With the increase of frequency, the correlation coefficient between PTA and NB CE-Chirp ASSR response threshold showed an upward trend. The frequency with the highest coefficient was 4 000 Hz, and the r values were all greater than 0.9, followed by 2 000 Hz, and the correlation coefficient was relatively low at 500 Hz. In the extremely severe group, each frequency coefficient was greater than 0.7, showing a strong correlation. Conclusion:NB CE-Chirp ASSR has good frequency specificity and can reliably assess hearing thresholds in hearing-impaired children.
