Neonatal hearing screening
Neonatal hearing screening is a crucial diagnostic tool that is used to detect hearing loss in newborn babies. It is typically performed before the infant leaves the hospital after birth, usually within the first few days of life. The screening process involves the use of specialised equipment to measure how well a newborn responds to sounds of varying pitch and volume.
The main goal of neonatal hearing screening is to identify infants who have hearing loss as early as possible. Early detection of hearing loss is essential to ensure proper language and cognitive development in babies. It is estimated that approximately one to three out of every 1000 infants are born with some type of hearing impairment.
There are various methods used in neonatal hearing screening, including otoacoustic emissions (OAE) and auditory brainstem response (ABR) testing. OAE testing measures the sounds that are produced by the inner ear in response to stimulation, while ABR testing measures the electrical activity of the auditory nerve and brainstem in response to sounds.
According to a study published in the South African Journal of Child Health, the prevalence of hearing loss in newborn babies in South Africa is estimated to be between 0.77% and 1.48%. However, the prevalence may vary depending on the population and the screening method used.
Hearing loss in newborn babies can have significant implications for their development. If left undetected and untreated, it can lead to delayed speech and language development, academic difficulties, and social isolation. It may also impact the overall quality of life and well-being of the child and their family.
Early detection and intervention are crucial to prevent these negative consequences. Newborn hearing screening programmes have been implemented in many hospitals in South Africa to ensure that hearing loss is identified early and appropriate interventions are provided. Timely intervention can improve the speech and language development of children with hearing loss, enabling them to reach their full potential.
Ideally, the recommended timeframe for conducting a particular test is within the first four to five weeks of age. However, it is also acceptable to conduct the test up to the three-month mark. It should be noted, however, that there may be constraints when conducting the test beyond the recommended period. This emphasises the importance of timely evaluation, which can efficiently assess and address any developmental concerns that may arise. It is advisable to adhere to the recommended timeline, to ensure the best possible outcome for the infants’ developmental well-being.
Parents may feel a sense of worry or despair when they receive news that their baby has failed the neonatal hearing screening test. However, it is important to remember that there can be several underlying factors that contribute to this outcome. One of the most common reasons for a failed hearing screening is the presence of fluid in the middle ear, which is easily correctable with treatment. Therefore, parents need not stress too much when their babies fail the screening, as there are various ways to address the issue and ensure that their child receives the necessary support and care. It is crucial, however, to consult with a healthcare professional to determine the root cause of the hearing deficiency and develop an appropriate action plan.
