According to the latest statistics, there are currently nearly 200 million people suffering from hearing impairment in my country, among which children account for about 50%. It seems that hearing care must start with babies.The following six factors are the main causes of children’s hearing impairment, and parents should pay full attention to them.
掏耳
When the child yells about itchy ears, some parents will pick up hairpins, short wooden sticks, wool needles, etc., and even use their long fingernails to blindly dig in the child’s ears.At this time, as long as you are slightly negligent or accidentally bumped by others, it is very easy to puncture the thin tympanic membrane deep in the child’s ear canal, causing rupture and perforation of the tympanic membrane, not only causing earache and bleeding, but also causing the outer ear and middle ear cavity. If the tympanic membrane is directly connected, the bacteria will take advantage of the deficiency and cause infection. It is necessary to know that the tympanic membrane is involved in sound conduction. If the tympanic membrane is perforated, it will directly affect the hearing of children.
Otitis media
Due to the characteristics of the anatomical structure of the Eustachian tube, children with colds, sucking milk in a flat and supine position or nausea or vomiting often cause bacterial infections in the middle ear cavity and acute suppurative otitis media.When the pus in the middle ear cavity continues to increase, the child will cry because of the increased earache. The increased pressure of the pus in the middle ear cavity will also cause the tympanic membrane to perforate and rupture.If you do not seek medical attention in time or the treatment is not thorough, it will cause chronic suppurative otitis media. If the tympanic membrane is continuously damaged and the perforation becomes larger and larger, the impact on hearing will become more and more serious.
Drug poisoning
When a child suffers from a cold, a headache, or fever, if the doctor blindly injects the child with streptomycin, gentamicin, kanamycin and other ototoxic drugs, a small number of children with allergic constitutions will suffer from poisoning of the inner ear auditory organs, and obvious hearing loss, even deaf.If the illness occurs before the child learns to speak, the child may become deaf and mute.According to statistics, deafness caused by the use of such drugs accounts for 97% of drug-induced deafness.Therefore, the use of these ototoxic drugs should be avoided as much as possible.
trauma
The causes of ear trauma include: when the child is naughty, some parents give the child several slaps indiscriminately when the child is naughty; during the festive season, the firecrackers set off suddenly explode in the child’s ear, and a huge wave of air blasts into the ear canal inner tympanic membrane; when swimming, The child’s ear hits the water first; the above-mentioned trauma will cause the tympanic membrane to rupture and perforate, directly causing hearing loss.
noise
Some children often like to turn on the volume when watching TV or listening to music; some children also like to listen to stereo music, which is only a few hours after putting on headphones, and they don’t want to take it off when walking or doing homework. .As everyone knows, prolonged exposure to high-decibel noise can cause undesirable stimulation to the nerve endings of the inner ear auditory organs and cause great damage to hearing.
Peri-auricular disease
Diseases of nearby organs around the ears sometimes involve the middle ear cavity, causing hearing loss.Such as rhinitis, paranasal sinusitis, tonsils.
