The occurrence and formation of human ear organs begins in the third week of viviparous birth, and the middle ear cochlea appears in the fifth week. Later, with the development of the fetus and infants, the auditory organs continue to be healthy and mature.Therefore, experts say that the formation and development of the auditory organs during the fetus and infants are vital, and the protection of hearing should start with the fetus and infants.

Experts said that we must first pay attention to the genetic history and family history of deafness.Congenital deafness usually has its family history. In addition to ear dysplasia, it is often accompanied by other organ malformations and visceral ectopics, which constitute various syndromes.The focus of congenital deafness is prevention, eugenics is promoted, and blood relatives or close relatives marriage are prohibited.For fetuses, infants and young children whose parents have a history of drug-induced deafness, such drugs should be avoided.For pregnant women, it is necessary to prevent viral infections.Maternal pregnancy with viral infections (such as viral influenza, rubella, etc.), especially the first 3 months of pregnancy, is an important stage in the development and formation of fetal auditory organs, which can cause hypoplasia or defects in fetal auditory organs.At the same time, avoid abdominal radiological diagnosis and treatment during pregnancy to avoid radiation damage to the fetal auditory organs.

For newborns, premature babies, neonatal asphyxia, fetal head trauma, neonatal jaundice, hemolytic diseases, etc., can cause hearing organs and auditory nervous system damage, hypoxia, insufficient blood supply and hearing impairment.

For young children, avoid using gentamicin, streptomycin, kanamycin, tobramycin and other ototoxic drugs.Avoid long-term and continuous exposure of infants and young children in a noisy environment to prevent physical and permanent hearing damage.In addition, pay attention to preventing otitis media.The Eustachian tube (that is, the Eustachian tube from the nasopharynx to the middle ear) of infants and young children is shorter, thicker, and straighter than adults. During breastfeeding, milk easily overflows from the nasopharynx into the middle ear, causing frequent otitis media and mastoiditis.Therefore, when a child is breastfeeding, it is necessary to adopt an appropriate position: tilt the head upwards, avoid breastfeeding in a supine position, and not too rush when breastfeeding.Children cry more than ever, and check for otitis media when they have a fever.

Experts remind that early detection of children’s hearing impairment and necessary treatment is the key to saving children’s hearing impairment.The normal development of infants and young children’s hearing: Hearing-turning reaction occurs at 3 months, and audible blinking reaction or miotic reaction may occur at 4 to 5 months. If necessary, you can go to the specialist department for examinations such as hearing and inner ear X-rays.Early intervention treatment, use of residual hearing, and language training can help some children get out of deaf-mute state.
