What does hearing screening mean?
Hearing screening is to see if the baby’s ear is working with a simple test. It is a simple, initial test that can be done quickly, takes a very short time and can show that there is a problem or not. In cases where there is the impression that there is a problem, more comprehensive investigations will be required. Hearing loss in 1 in every 1000 babies; may cause learning disability in the child and not to communicate with his / her friends. Hearing loss, which seriously hinders social and physical development, can slow development if it is not diagnosed early and measures are not taken.
When should hearing screening be performed in newborn babies?
Hearing screening for newborns should be done while the baby is in the hospital. If, for any reason, the baby has left the hospital without testing, or the baby was born outside the hospital, the baby is asked to perform the test before the first 3 months. The baby or child, who has not passed the hearing screening test and is suspected to have hearing loss, is initially get examined and then evaluated with BEAP and audiometry hearing tests, at any age.
The most common hearing screening test is AOE (auto-acoustic emission) test. This test is done while the baby is asleep. The sound is given to the ear from one end placed at the entrance of the outer ear canal and the return reflection is measured. If there is a return reflection, that baby’s ear is considered to be hearing normally.
Diagnosing discomfort by carrying out these tests in the early period is of great importance in terms of deciding treatment.
In addition to newborns, hearing assessment should be done periodically in early childhood.
- Some diseases passed in childhood,
- medicines used,
- Genetic disorders associated with progressive hearing loss etc.
For many reasons, hearing loss can be observed after the neonatal period. Since it may take time for the hearing loss to be recognized by the family in babies and children, it is important to follow the process with regular controls.
