Abstract
Auditory Neuropathy (AN) poses a substantial challenge in neonatal auditory screenings due to its complex course and potential for delayed onset. Early identification and intervention are important for optimizing developmental outcomes. This study aimed to explore the prevalence, determinants, and temporal progression of AN in neonates, and assess the therapeutic benefit of amplification devices on their communication skills. The study utilized a longitudinal cohort design to analyze a cohort of 200 neonates from a tertiary care center over the duration from January 2021 to December 2022. Auditory evaluations were conducted at specified intervals, utilizing a comprehensive battery of auditory assessments. Statistical analyses, including regression models, were employed to identify associations between various determinants and the progression of AN. The results of the study revealed a significant correlation between low birth weight and familial history with onset of AN. The data also revealed a gradual rise in AN prevalence over the study duration. However, a negative correlation was observed between AN severity and communication skills. The utilization of hearing aids was associated with enhanced communication outcomes. The study highlights the importance of comprehensive auditory screenings in newborns, particularly emphasizing the early detection and intervention of AN. Based on empirical findings, it emerged that amplification devices, particularly hearing aids, have the potential to mitigate the detrimental effects of auditory neuropathy (AN) on communication skills. This study provides a valuable contribution to the academic debate by highlighting the need for strengthening neonatal auditory screening protocols. The findings have profound implications for clinical practices, highlighting the role of early interventions in optimizing developmental prospects for neonates diagnosed with AN.
