1, the baby “hearing screening failed” do not need to panic in normal newborns, the incidence of bilateral congenital deafness is about 1 per 1,000 ~ 3 per 1,000, because the hearing screening instrument is sensitive, the screening results are affected by more factors, such as when the screening of the surrounding environment noise changes, the baby’s quiet degree (such as body movement), the baby’s external ear canal (such as residual The hearing screening may not be passed if there is secretion in the middle ear or amniotic fluid, or if the baby is not breathing well due to nasal blockage. Domestic and international data show that the percentage of failed initial screening (from the third day of life to discharge) is around 10%, which means that the probability of a failed initial screening resulting in a diagnosis of a hearing problem is only 1-3%. Most of the babies who fail the hearing screening are not found to have a clear hearing loss after the diagnostic hearing test, which is mostly due to the absorption or discharge of existing secretions from the external ear canal or middle ear. 2. 42 days must go to “hearing re-screening” 2.1 Passing re-screening When you take your child to “hearing re-screening” at 42 days, if it passes, congratulations, it is generally considered that the child’s hearing is normal. No further tests are needed for the time being. However, as your child grows up, you should keep an eye on how your child responds to sounds or whether he or she is about the same age as the children around him or her, and if there is a large difference, you should go to the hospital to rule out any hearing problems. 2.2 Failure to pass the re-screening When you take your child for a “hearing re-screening” on day 42, if he or she still fails, you should not be too alarmed because although the re-screening is not passed, the chance of being diagnosed with a hearing problem is only about 1 in 10. 3. Remember to have a diagnostic hearing test before 3 months of age Always remember to take your baby to a reliable pediatric diagnostic hearing center for a diagnostic audiology test and medical examination within 3 months of age (not necessarily until 3 months, the earlier the better). Even a “failed hearing screening” in one ear is not an exception. If a hearing problem is diagnosed in one ear, it is even more important to pay attention to the child’s hearing, since the rate of delayed hearing problems in such children is significantly higher. 3.1 What tests should be done? (1) Acoustic conductance of high frequency sound (1000 Hz) (2) Otoacoustic emissions (3) Auditory brainstem response These three tests are the basic tests that must be done. If not, it depends on the specific results, and if necessary, additional tests should be done to understand the degree (mild, moderate, severe, very severe), nature (conductive, sensorineural, mixed) and location (outer ear, middle ear, inner ear and auditory nerve) of your baby’s hearing loss, and sometimes some medical evaluations other than hearing are needed; at this time, it is best to find a doctor who is proficient in pediatric audiology to interpret the results of the tests and make a comprehensive assessment. You should find a doctor who is well versed in pediatric audiology to interpret and evaluate the results of the test. Finally, it is important to emphasize that it is not the discovery of a hearing problem that is scary, but the lack of action. Even if your child has a hearing problem, if you intervene early (within 6 months of age), the scientific methods available today can allow your child to speak normally. In the past, it was often said that “nine out of ten deaf children are dumb”, but now we are working together to achieve “nine out of ten deaf children are not dumb”. If your child has a hearing problem, please pay attention to the following questions, which may be necessary for you to understand. (1) What is considered normal hearing or diagnosed by hearing? (2) How is hearing loss determined? (3) When and where do I need a hearing aid? (4) How do I know if I have the right hearing aid? (5) What is the relationship between cochlear implants and hearing aids and how to choose? (6) Other
