Care of the Ears in Newborn Infants
The best chance to protect the baby’s ears is when you have not yet discharged from the hospital. Minors must be under constant review the first three months of life, because they can develop hearing problems. While few babies that come into the world with these types of conditions in the United States, one in every thousand children born deaf.
The development of language skills typically appears during the first three months and decreased hearing acuity may interfere with the healthy evolution of language, social and emotional growth.
Currently, there are various methods for identifying aural discomfort. Some children’s diseases are associated with risk factors such as family history and low birth weight. However, these criteria fail by 50 or 70% at the time of diagnosis of hearing difficulties.
Recent technological advances are aimed at increasing prevention methods. There are two universal procedures: otoacoustic emissions and audiometry. The review of otoacoustic emissions measured sounds inaudible, low, occurring in the inner ear. This demonstration can be applied to newborns before leaving the hospital.
Children who do not successfully pass the test of otoacoustic emissions should undergo a hearing test to measure brain responses, which evaluate the functions of the auditory nerve and parts of the brain involved in the audition process.
While audiometry is an expensive method, which requires much time and have technical difficulties, recent research shows that the otoacoustic emission tests are fast, inexpensive and noninvasive, to be applied to newborns from the outset.
