What is newborn hearing screening?

Newborn hearing screening is a regular item, usually after the child is born48After hours; if the first screening fails, it needs to be after birth42Day again; if the review still fails, it needs to be born after3Referred to the professional hearing impairment clinic for further screening. Neonatal hearing screening is mainly to screen the otoacoustic reflex and middle ear acoustic impedance test. This test shows that the baby’s external auditory canal can record the normal otoacoustic reflex, indicating that the baby’s peripheral auditory organs function normally. Of course, even if the baby passes the preliminary screening, it will inevitably encounter various factors that cause hearing loss in the future growth process. Therefore, parents still need to pay close attention to the child’s hearing and language development status. If abnormalities are found, they should be treated immediately. Beware of delays. Hair loss hearing loss occurs. If the baby does not pass the first screening, it does not mean that the baby has problems in hearing, because there are many factors that lead to the failure of the primary screening, such as residual amniotic fluid in the external auditory canal, bloody substances, etc., which may cause blockage of the outer ear. There may be middle ear effusion. It may also be because the cochlea is not yet fully developed or sick, or it may be that the environment is not quiet and noisy when testing, etc., when parents do not have to worry too much. The first screening failed, it should be after birth30 ~ 42Re-screening again in the day, if it still fails, it should be3The third screening was conducted around the month.

If the third time to eliminate the ear canal blockage and excessive secretion of the ear and other factors, still failed to pass, this time should take the child to the child hearing diagnosis and treatment institutions for diagnosis and treatment. Of course, the vast majority of babies are here1/2/3Pass through the screening. It should be noted that even if the child passes the hearing screening, parents will need to pay close attention to the child’s hearing during the subsequent growth process, because there are many congenital or secondary high-risk factors leading to delayed hearing impairment.
