Three types of dangers should be paid attention to to protect hearing in childhood

Domestic statistics show that acquired deaf children account for 67% to 86% of deaf children.The disease usually occurs in children between the ages of 5 and XNUMX years old. Because of their liveliness, poor awareness of danger and protection, they are vulnerable to injury.

Drug-induced deafness

Drug-induced deafness is caused by the mutual influence of genetics and environment. The disease is caused by toxic damage to the auditory nervous system caused by the use of certain drugs for treatment or exposure to certain chemical agents, causing hearing loss, dizziness and even total deafness.Some children are extremely sensitive to aminoglycoside drugs because of maternally transmitted mitochondrial gene mutations.Drug-induced deafness caused by aminoglycosides is lifelong deafness, and there is currently no cure.

Every year, more than 60% of newly deaf children in my country are drug-induced deafness.In addition to the well-known streptomycin, there are more than 20 kinds of aminoglycoside antibiotics commonly used clinically, such as kanamycin, ribomycin, gentamicin, and tobramycin. When using aminoglycoside antibiotics, you must pay attention to: ①Combination with strong diuretics can increase ototoxicity; ②Combination of two aminoglycoside antibiotics not only does not expand the antibacterial effect, but also enhances the damage to the eighth brain nerve and the toxicity to the kidney.

During pregnancy (especially the first 3 months of pregnancy), mothers should disable drugs that damage the inner ear of the fetus (such as streptomycin).When children must use ototoxic drugs, they should be closely observed, paying special attention to tinnitus and dizziness.

Deafness caused by infectious diseases

Certain infectious diseases, especially viral infections (such as meningitis, measles, scarlet fever, and diphtheria, etc.) can cause deafness or hearing loss.Among them, secretory otitis media is the most common.

Due to the characteristics of the physiological structure of the ear, children with upper respiratory tract infections, sucking milk in a flat and supine position, or nausea or vomiting often occur bacterial infections in the middle ear cavity, resulting in acute suppurative otitis media.There is increasing pus in the middle ear cavity, and children will cry because of increased earache. The increased pressure of pus can also cause perforation or rupture of the tympanic membrane.If you do not seek medical treatment in time or the treatment is not thorough, chronic suppurative otitis media can be caused, the tympanic membrane is constantly destroyed, and the impact on hearing will become more and more serious.

When treating children with secretory otitis media, nasal astringents should be used to make the nasal cavity unblocked and antibiotics should be used. If necessary, treatments such as eustachian tube dilation or tympanic membrane puncture should be used, and the predisposing factors (such as hypertrophy of proliferators) should be treated.Since the common pathogens are mainly pneumococcus or Haemophilus influenzae, prevention of upper respiratory tract infection is an important measure to reduce the incidence of otitis media.

Traumatic deafness

Ear trauma, head trauma, concussion or incorrect ear extraction can all cause traumatic deafness.Parents should avoid an improper method (such as slamming their head) to educate their children.For young children, careful care should be taken to prevent their head from falling.When setting off firecrackers during the holiday season, parents should ask children to stand farther to avoid damaging their tympanic membranes.
