İşitme Cihazı Kullanan Çocukların Kortikal Cevapları ile Davranış Eşiklerinin Ilişkisi

Abstract

The cortical auditory evoked response is the neuroelectric response of the auditory system in the brainstem, midbrain, and the cortex to sound stimulation. Cortical auditory evoked potentials are a noninvasive, objective measurement that can provide detailed information about central auditory nervous system. They can be used for evaluation of hearing aid functionality. The present study aimed to determine the relationship between aided cortical auditory evoked potentials and aided behavioral thresholds. Therefore, 17 subjects, age ranging 4-8 years old, who diagnosed with moderate/ moderately severe hearing loss were included to the study. Pure-tone audiometry was performed using supra-aural earphones. After control of hearing aids, aided behavioral thresholds were determined in free field. After behavioral testing, cortical auditory evoked potentials testing was carried out. A strong correlation was found between aided cortical auditory evoked responses and aided behavioral thresholds in free field. These findings provide support for the use of cortcal auditory evoked potentials in measuring hearing aid benefit in clinical rotuine.
