Abstract
Cochlear implantation (CI) is the most effective rehabilitation method for children with congenital deafness and patients with late-onset deafness. It involves the insertion of an electrode array into the cochlea to stimulate the auditory nerve, which the brain then interprets as sound. A key component of rehabilitation is fitting the CI processor to create a unique sound perception pattern for each patient. Consequently, the development of new tools for CI fitting is a vital area of focus in hearing rehabilitation. This study included 30 patients with bilateral sensorineural deafness (n = 50 ears), consisting of 13 boys (43.3%) and 17 girls (56.7%). Patient age ranged from 6 to 14 years (M = 7.5 ± 2.58). Hearing thresholds were determined for all patients using free-field pure-tone audiometry and auditory steady-state response (ASSR) recording. The correlation between the results of these two methods was then analyzed. The strongest correlation between free-field behavioral and ASSR thresholds was observed at 500 and 4000 Hz. At frequencies of 1000 and 2000 Hz, a moderate correlation was found. ASSR serves as an objective alternative to pure-tone audiometry for evaluating the entire CI system. It may be valuable for sociomedical assessment and system verification. Despite the lack of correlation between hearing thresholds and speech intelligibility, ASSR is an additional tool for objective auditory assessment in pediatric patients during early rehabilitation.
