There are many overlooked overlooking hearing loss depending on the inspection method

――How is the hearing test for your baby actually performed?Morimoto Currently, the newborn hearing screening test has an automatic ear sound sound radiation (hereafter, automatic OAE) and an automatic hearing brain trunk (hereafter, Auto ABR), and a first test will be conducted within 3 days after birth.Automatic OAE is a method of attaching an earphone -like equipment to the baby's ear, and detecting the sound that the cochlea in the ears reacts and emitted from the sound coming out.Auto ABR is a method of attaching an electrode to the baby's forehead, attaching disposable earphones to both ears to hear small sounds, and detecting electrical reactions from the brain from the electrode.There are many facilities that have been inspected by automatic OAE nationwide, but there is a problem that automatic OAE has many overlooked inspections.――What does it mean to have many oversight?Morimoto Automatic OAE is a test of the reaction of the cochlea, so it has no problem with the inner ear function, but overlooks hearing loss when the nerve function is abnormal."Pass" is called "pass" that there is no problem in hearing tests, and the need to be re -examined is called "refere".In some cases, it was a special hearing loss that the cochlea was normal, but there was no hearing nerves because the cochlea was actually normal.In addition, it is said that automatic OAE has a higher rat of refiner than automatic ABR, and is more likely to be false positive.The fact that there is a false positive is that it is said that it is actually normal but a precision test, and you may be worried about your moms.According to a survey by the obstetrics and gynecology association, 98 delivery facilities that allow newborn hearing screening to be tested in 2020..There was 1 %.However, not all facilities have introduced automatic ABR, and there are many facilities that use automatic OAE.The reason is that OAE may be less expensive because the inspection is easier and the accessories are not disposable.However, looking at the ratio rate and the possibility of overlooking special hearing loss, I think that it is better to perform a newborn hearing screening test with automatic ABR.I want pregnant women and moms and dads to know this widely.
