ABSTRACT
Hearing loss is likely to be the most common congenital abnormality in newborns, with a reported prevalence of 3 per 1000 live births. It is vitally important to diagnose infant hearing loss or deafness at its early stages. The automated auditory brainstem response (AABR) screener is a dedicated hearing screening device which provides information not only about the outer and middle ear and cochlea but also about the auditory pathway up to the brainstem. The data presented were collected in the well-baby nursery. Overall, data from 5857 neonates screened from December 2012 to July 2015 were analyzed in this study. During 1-3 days after birth, they were analyzed with automated auditory brainstem response (AABR). Neonates referred the screening were scheduled for repeated diagnostic evaluation within a month. And newborns referred again were sent to a specialist for further audiology analysis. Out of the 5857 babies screened, 5050 passed bilaterally and 807 referred. The number of infants referred for 2nd stage, post-discharge re-screening was 319. Of this group, 287 passed bilaterally and 32 failed the re-screening in one or both ears. Diagnostic testing was performed on all of the 32 infants who were referred. The resulting referral rate was 13.7% for first stage and 1,4% for second stage. The follow-up rate was 37%. The confirm rate was 0,13%. Profound bilateral sensor neural hearing loss was identified in 3 infants. Profound bilateral mixed hearing loss was identified in 1 infant. Automated auditory brainstem response (AABR) was efficient in the early identification of newborn and infant hearing loss with high sensitivity and specificity rates. Due to the results of the study, 3 out of 5857 infants were diagnosed with a profound hearing loss and it’s approximately close to the results of other studies and statistics.
