With the increase of various factors harmful to hearing, more and more people have hearing problems. In the past, many people felt that the hearing problem seemed to be only the problem of the elderly, but now more and more young people and even children have hearing problems. So, do you know the causes of hearing problems?
Causes of hearing loss
Reason 1: ear pulling
When children shout that their ears are itchy, some parents will casually take hairpins, short wooden sticks, wool needles and other things, and even directly use their slender fingernails to dig blindly in their children's ears. At this time, as long as you are slightly negligent or accidentally collided by others, it is very easy to puncture the thin tympanic membrane deep in the child's ear canal, resulting in tympanic membrane rupture and perforation, which will not only cause ear pain and bleeding, but also make the outer ear directly connected with the middle ear cavity, and bacteria will take advantage of the weak point and cause infection. You should know that the tympanic membrane participates in sound transmission. If the tympanic membrane is perforated, it will directly affect the child's hearing.
Cause 2: Otitis Media
Due to the characteristics of the anatomical structure of the eustachian tube, children often cause bacterial infection in the middle ear cavity and acute suppurative otitis media when they catch a cold, suck milk in a flat position, or nausea and vomiting. When the pus in the middle ear cavity is increasing, the child will cry because of the aggravation of earache. The pressure of the increased pus in the middle ear cavity will also cause tympanic membrane perforation and rupture. If you do not seek medical treatment in time or treat it incompletely, it will cause chronic suppurative otitis media. For example, the tympanic membrane is constantly damaged and the perforation is becoming larger and larger, and the impact on hearing will become more and more serious.
Cause 3: drug poisoning
When a child has a cold, headache and fever, if the doctor blindly injects the child with ototoxic drugs such as streptomycin, gentamicin and kanamycin, it will lead to poisoning of the inner ear auditory organs of a few children with allergic constitution, obvious hearing loss and even deafness. If the disease 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 far as possible.
Cause 4: Trauma
The causes of ear trauma include: when the child is naughty, some parents, in a rage, indiscriminately slap the child; During the festive season, firecrackers suddenly exploded in the child's ear, and a huge air wave rushed into the tympanic membrane in the ear canal; When swimming, one side of the child's ear hits the water first; The above trauma will cause tympanic membrane rupture and perforation, which will directly cause hearing loss.
Reason 5: noise
Some children tend to turn up the volume when watching TV or listening to music; Some children also like to listen to stereo music. They wear headphones for hours and don't want to take them off when walking or doing their homework. As everyone knows, exposure to high decibel noise for a long time will cause adverse stimulation to the nerve endings of the inner ear auditory organs and great damage to hearing.
Cause 6: periauricular lesions
Lesions of adjacent organs around the ear sometimes involve the middle ear cavity, resulting in hearing loss. Such as rhinitis, paranasal sinusitis and tonsil.
How to prevent hearing loss
First, a reasonable diet
Eat less foods that are too sweet, salty and creamy every day to prevent arteriosclerosis, inner ear ischemia and hearing loss.
Second, quit smoking and alcohol
Because tobacco and alcohol have toxic effects on the auditory nerve, especially when nicotine in tobacco enters the blood, it will spasm small blood vessels, slow blood flow and increase viscosity, resulting in insufficient blood supply to the inner ear, resulting in deafness.
Third, avoid noise damage
Noise will make the hearing that has begun to decline more prone to fatigue, resulting in spasm of the micro blood vessels in the inner ear, reducing the blood supply to the inner ear, resulting in hearing loss. Therefore, when listening to music, watching TV and listening to music with headphones, it is not appropriate to turn the volume too high, which is generally about 85 dB.
Fourth, avoid pulling out your ears and massage often
Ear digging is a bad habit. It is easy to hurt the ear canal, cause infection, inflammation, and even damage the eardrum. When the ear canal is itchy, you can gently wipe the ear canal with a small cotton swab soaked in a little glycerol or alcohol. Persisting in massaging Yifeng point and hearing point before and after earlobe can increase the blood circulation of inner ear and protect hearing.
Fifth, keep a happy mood and take more exercise
Excessive fatigue and mental tension will cause inner ear ischemia and affect hearing, such as anger, anger, etc. At ordinary times, taking more exercise within one's ability, such as outing, early morning walk and Taijiquan, can promote the blood circulation of the whole body, strengthen the blood supply of the inner ear and delay the aging of organs.
