Why are children deaf?

Congenital cause

Congenital deafness is related to genetic factors, pregnancy and labor process. If pregnant women are infected with rubella, cytomegalovirus, herpes simplex virus and syphilis during pregnancy, they may cause congenital deafness in newborn.

Pregnant women who have taken antidiabetic drugs such as Jiangtangling, aminoglycoside drugs such as gentamicin and kanamycin during pregnancy can also cause fetal deafness. Pregnant women who have been exposed to radiation, radiation therapy or hypothyroidism during pregnancy can also cause neonatal deafness


Noise is an important factor that directly causes hearing loss, and it is also an important inducement for children’s deafness. When the mother of the fetus is in the stomach, if she stays in the noise environment for a long time, there is a great chance that the child will be deaf after birth. There are also cases like this. After birth, the baby will form imperfect hearing about one month. If the surrounding environment noise is serious, it will often cause hearing impact on the child. The noise is measured in decibels, 30 decibels for a gentle conversation at home, 40 decibels for a normal conversation, 80 decibels for a high voice, and 90 decibels for a loud or loud speaker. Noise below 40 decibels has no adverse effect on children, and noise above 70 decibels will cause damage to children’s auditory system.


Postnatal deafness is related to asphyxia, hemolysis and trauma in the process of birth. After birth, if the newborn is infected with such viruses as meningitis, encephalitis B, measles, scarlet fever, typhoid, tuberculous meningitis, influenza, mumps, rubella, varicella, etc., it will also cause deafness.

Otitis media

The reason why we put forward otitis media is that if children suffer from chronic otitis media, if they are not treated in time, they will often develop into sensorineural deafness. But in the life the parents often because each kind of neglect causes the child to suffer from the tympanitis. Cold is one of the main causes of otitis media. Prevention of cold can reduce the incidence of otitis media. Blowing your nose in the wrong way can also cause otitis media. The right way to blow your nose: hold one nostril with your finger, blow the other nostril slightly, and blow the other nostril with the same method. If the infant sucks in the supine position, because the eustachian tube of the infant is relatively straight, the lumen is short and the inner diameter is wide, the milk can be choked into the middle ear through the eustachian tube to cause otitis media. Therefore, the mother should take the seat when feeding the baby, hold the baby in an oblique position, and suck the milk leaves vertically on the head.

Ototoxic drugs are also important factors leading to deafness in children. The drugs leading to deafness mainly include glycosaminoglycan, salicylic acid, antitumor and alcohol. The common ones are streptomycin, dihydrostreptomycin, neomycin, kanamycin, gentamicin, vancomycin, zimycin, tobramycin, bamycin, polymyxin B, quinine, aspirin, etc. Although most hospitals have banned these drugs now, they are still used in places with low medical level, so parents should also pay attention.


When children are naughty, some parents slap their children vigorously in anger; during the festive season, the firecrackers suddenly explode in their children’s ears, and the huge waves of air directly hit the eardrum in the ear canal; when swimming, the ears hit the water surface, all of the above external forces will cause the eardrum to rupture, perforation, and directly cause hearing loss.

Periauricular diseases

The pathological changes of the adjacent organs around the ear sometimes involve the middle ear cavity, thus causing hearing loss. Such as rhinitis, sinusitis, tonsillitis, etc.

The causes of deafness in children now say these points, I hope parents and expectant mothers pay attention to them.
