Abstract
Aims of the Work
Considering the objectivity, sensitivity and reliability of OAEs and ABR to test cochlear and auditory brainstem functions, both tests are widely accepted methods to evaluate the auditory functions in neonates, infants and young children. This study was designed to evaluate auditory function in neonates at risk for hearing loss aiming for early detection and interference for such hearing loss if any.
Conclusion
This study revealed that the risk factors for SNHL had variable effects on the auditory pathway.
The site of lesion was located to be in the cochlea in most of the risk factors. On the other hand; retrocochlear lesion was located in all neonates with hyperbilirubinemia required exchange transfusion that showed hearing loss and only 25% of neonates with asphyxia. Overall, cochlear hearing loss represented 47% of all neonates having hearing loss, while retrocochlear hearing loss represented 53% of neonates have hearing loss.
Recommendations
Considering the high prevalence of hearing loss among neonates having one or more risk factors, we recommended that every neonate with risk factor for hearing loss must be evaluated audiologically early in life for early diagnosis and intervention which would minimize the detrimental effects of hearing loss. Also neonates at risk factors for SNHL must be followed up. Mothers also should receive good antenatal care to prevent intra-uterine hypoxia, trying to treat TORCH infections.
