Patient's question:
My baby is just 45 days old. At three days and 42 days after birth, hearing tests were conducted, and both ears failed the screening. I am very anxious. Could you please tell me what could be the reasons for this and what should be done? Newborn hearing screening systemDoctor's answer:
Generally, it is necessary to check. ?Newborn hearing screening is an objective, simple, and rapid method to screen newborns who may have hearing impairment for further diagnosis and follow-up. Common methods of newborn hearing screening include Auditory Brainstem Response (ABR) and Otoacoustic Emissions (OAE). Both of these methods are internationally recognized non-invasive techniques. OAE is used for hearing screening in most hospitals in China, while ABR is primarily used for newborn hearing screening in intensive care units. A normal cochlea produces very soft sounds, which are transmitted through the ossicular chain and eardrum to the external auditory canal and can be detected. If a baby has cochlear hearing loss, OAE will not occur, and the OAE test will fail. ABR can reflect the function of the external ear, middle ear, cochlea, and cochlear nerve pathways.
