Comparison of Oto-acoustic Emission Test and Automated Auditory Brainstem Response in Detecting Hearing loss among Newborns and Infants at a Tertiary Private Hospital

Hearing loss is a global burden, even in developed countries. Global estimates in developed countries revealed that 1 to 5 of 1000 babies are born deaf. Prevalence of hearing loss increases as parents’ literacy rate decreases. Development of screening programs to identify persons with hearing loss is needed because the outcomes of this disability cascades throughout the person’s lifetime. Provision of a high quality of early intervention must be prioritized for the infants with hearing impairment to optimize their language and literacy development. The goal of universal newborn hearing screening is to detect permanent hearing loss averaging 30dB or more in the frequency region important for speech recognition (500-4000 Hz). Several published studies have revealed weakness in the newborn hearing screening program. Some of the weaknesses are failure to detect late-onset deafness, and failure of some children who did not pass the initial screening to return for follow-up. Additionally, there are false-positive results in many newborn hearing screening programs. Consequently, centers began looking for ways to improve services by having a low failure rate yet also detect infants with congenital hearing loss. The drawback in the Oto-acoustic Emission test is that it does not detect fluctuating hearing loss or those caused by auditory neuropathy. On the other hand, Automated Auditory Brainstem Response detects only moderate to profound hearing loss. These factors suggest a need to investigate the capability of Automated Auditory Brainstem Response as a screening tool for hearing loss among infants and compare that capability with the capability of the Oto-acoustic Emission protocol.

• To determine the demographic and clinicall profile of patients with hearing loss
• To determine the prevalence rate of hearing loss among infants born in a tertiary hospital
• To determine the sensitivity, specificity, positive predictive value and negative predictive value of AABR and OAE and ABR
