Hearing loss prevention methods

Noise prevention in daily life

If long-term exposure to machine roar, noise in the workshop, human noise, etc., will cause the tiny blood vessels in the inner ear to often be in a convulsive state, the blood supply to the inner ear will decrease, and hearing will decrease sharply. Therefore, to avoid or reduce the interference of noise as much as possible is the number one priority for hearing protection.

Maintain a good mental state

If you are often in a state of irritability and irritation, it will cause the autonomic nerves in the body to lose their normal regulating function, which will cause ischemia, edema and hearing impairment in the inner ear organs, which will cause sharp hearing loss. Therefore, try to keep yourself relaxed and happy.

Massage

Massage the acupuncture points at the front and back of the earlobe (in the depression of the earlobe and the high bone behind the ear) and the hearing point (in front of the tragus and the depression of the posterior margin of the mandibular joint process) to increase blood circulation in the inner ear and protect hearing Role. It is advisable to massage each morning and evening every day for 5-10 minutes each time. If you persist for a long time, you will see results. Recommendation: Very effective ear exercises.

Pay attention to medication

Try to avoid the use of ototoxic drugs, such as gentamicin, streptomycin, kanamycin, neomycin, etc. These drugs easily cause ear poisoning and damage hearing. Patients with neurological deafness should pay more attention!

It's better not to dig your ears

Dig ears often with ear spoons and match sticks, which can easily hurt the ear canal, cause infection, inflammation, and damage the eardrum. When the ear canal is very irritable, you can use a cotton swab with a little alcohol or glycerin to wipe the ear canal, or take vitamin B, C and cod liver oil.

Healthy way to nourish kidney

Chinese medicine believes that the kidneys open to the ears and hearing loss is closely related to kidney deficiency. Therefore, you can take more kidney foods, such as walnut porridge, sesame porridge, peanut porridge, pig kidney porridge, etc. These foods are very helpful for hearing protection.

Do not use the headset for too long

When you often use mp3, mp4 or mp5 to listen to songs or watch videos with headphones, remember not to adjust the volume too much, and do not use it for a long time, because this will reduce your hearing. Do not use headphones.

Differential diagnosis of hearing loss

Hearing loss is commonly referred to as deafness in medicine. Deafness does not mean that no sound can be heard, but there are some differences, such as mild, moderate and severe, and even deafness. Generally, we divide deafness into three types: deafness, sensorineural hearing loss, and mixed hearing loss according to the lesion site:

Transonic deafness: refers to the hearing loss caused by the transmission of the sound pressure transformer device, which affects the transmission of sound waves. The human ear's sound conduction is mainly air conduction, so the hearing loss caused by lesions in the structure of the external auditory meatus, tympanic membrane, ossicular chain, etc. are all deafness.

Embolism: blocks the external ear canal, hinders sound conduction, and causes hearing loss.

Perforation of the tympanic membrane: After the perforation of the tympanic membrane, sound waves are transmitted into the deep part of the external ear canal, causing energy leakage, which leads to hearing loss. This is like a broken drum at a mallet, and the sound is certainly not as good as a full drum head.

tympanic membrane indentation: It is mostly the result of abnormal eustachian tube function. Indentation of the tympanic membrane increases the tension of the tympanic membrane and changes the resonance frequency with the sound waves, which affects the transmission of sound.

Secretory otitis media: It is a non-purulent inflammatory disease in the middle ear cavity. Due to the accumulation of fluid in the tympanum, it affects sound transmission and reduces hearing. It's like a drum filled with water, and the sound of knocking out is muted.

Purulent otitis media: Both acute and chronic purulent otitis media can affect hearing, mainly due to tympanic secretion or tympanic membrane perforation.

Interruption of the ossicular chain: trauma to the middle ear causes joint dislocation or otitis media to corrode the ossicular chain and tympanic ossicular chain adhesion and fixation after otitis media, resulting in reduced sound amplification and affecting hearing.

Tympanic sclerosis: Calcium deposits in the structure of the tympanic cavity can be caused by various inflammatory diseases, and the function is limited, which affects sound transmission.

Transonic deafness generally does not cause total hearing loss. If pure tone hearing tests are performed, it is found that the air-conducted hearing loss generally does not exceed 60 decibels, which is moderate deafness, and bone-conducted hearing is basically in the normal range.

Sensorineural hearing loss: refers to hair cells, auditory nerves, and auditory centers at various levels in the ear spiral organs, which impedes the perception of sound and nerve impulses, causing sensorineural hearing loss. The common diseases are as follows:

Ear Sclerosis: Unlike tympanic sclerosis, ear sclerosis is a disease of unknown cause. It is a disease that occurs when the dense bone plate of the inner ear bone is lost and replaced with new sponge-like bone. This is the same as the wall of the house was replaced by the original solid bricks and concrete structures, and was replaced by sand and stone. Sturdy, but this osteoporotic lesion of the ear is only the first stage of the disease. After that, it will develop further. There is a large amount of fibrous tissue hyperplasia and calcification in the bone, just like cement placed in the open air. It will soon harden and harden. This stage is also called the sclerosis stage, so it is called otosclerosis. The consequences of ear sclerosis are changes in the structure of the inner ear, deformation and necrosis of nerve cells, and eventually hearing loss, which is mostly bilateral and continues to worsen. Hearing loss is more sensory.

Ammenier's disease: It is a disease with paroxysmal dizziness, fluctuating deafness, tinnitus, and ear fullness as the main symptoms. It is caused by edema of the inner eardrum, which is generally unilateral ear disease, young adults see.

(3) Congenital deafness: It can be caused by genetic factors, or because the mother is infected with a virus or other damage during pregnancy, causing hearing loss after the fetus is born.

Senile deafness: It is caused by degenerative changes in the hearing organs during the aging of the human body, so it is often found that the hearing of the elderly is not as good as that of the young.

Deafness caused by infectious diseases: A variety of acute and chronic infectious diseases can cause sensorineural hearing loss. Such as polio, diphtheria, typhoid, etc., but it is now rare.

Deafness caused by some other diseases throughout the body: Hypertension and arteriosclerosis are the most common. The reason is caused by the nutritional blood supply disorders of the inner ear. Others such as diabetes and hypothyroidism can also cause hearing loss.

Drug toxicity deafness: It is now clear that aminoglycoside antibiotics such as streptomycin, gentamicin, amikacin and the like have damage to the human ear and can cause sensorineural hearing loss.

Traumatic deafness: Traumatic brain injury results in labyrinthine concussion and skull base fracture, which can damage the inner ear and cause hearing loss.

Sudden Deafness: It is a sudden-onset deafness disease, which may be related to the inner ear blood supply disorder and viral infection.

There are many reasons that can cause sensorineural hearing loss. Sensorineural hearing loss can be divided into sensory hearing loss and neurological hearing loss according to the lesion. Sensorineural hearing loss is hearing loss caused by hair cell lesions. Neurological hearing loss is hearing loss caused by lesions in the auditory nerve and conduction pathways.

Mixed deafness: It refers to the hearing loss caused by mixing the two aspects of transmissive and sensory. For example, those who suffer from chronic suppurative otitis media have both tympanic membrane perforation and hearing deafness caused by damaged ossicles, and can also cause sensorineural deafness due to long-term absorption of bacterial toxins and damage to the inner ear hearing aids.

If young people have occasional short-term tinnitus, but will soon return to normal, this may be caused by sudden noise stimulation of the ears, or due to various reasons such as stressful work, stress, insomnia, etc., pay attention to daily life and use Ear habit will ease; if tinnitus persists for 1-2 days, you must go to the hospital for examination. Don't think that it is just tinnitus that does not affect hearing, it is not important, because some high-frequency deafness is only simple tinnitus at first, and hearing is not affected, but deafness will suddenly occur over time.

During the flight, the atmospheric pressure decreases rapidly during take-off, which can make the ears feel clogged. A few people may also have short-term hearing impairment and ear canal pain. This is because during the ascent or descent of the aircraft, due to the change in atmospheric pressure, the pressure in the middle ear tympanic cavity is abnormal, causing the eustachian tube to be compressed and blocked, making the middle ear tympanic cavity to be in a negative pressure state. Swelling and hearing loss. Therefore, you can chew gum during take-off and landing. With the chewing and swallowing action, the Eustachian tube will open and close at any time, and the air can freely enter and exit the middle ear cavity, so that the internal pressure of the middle ear and the external atmospheric pressure maintain a normal balance. The discomfort will be reduced or disappeared. People who are catching a cold, having an upper respiratory tract infection, or having problems with their nasal cavity are advised not to take a plane to avoid otitis media.

Young parents need to pay attention that children, especially infants, can easily cause ear inflammation and hearing loss due to upper respiratory infections. Especially for newborns, do not let the child lie down while holding the baby. Try to hold it obliquely. Otherwise, it will be easy to suck the milk. Once it can not be excreted in the ear, it will easily breed bacteria and cause ear infections.

Hearing decline factors

First, the baby has a relatively sound hearing one month after birth. At this stage, it is not suitable to receive large sound stimulation. Excessive stimulation may cause hearing damage. When taking a bath or washing your hair, be careful not to let sewage enter the ear canal to prevent the external ear. And the occurrence of otitis media.

Should pay attention to the correct feeding and feeding position, that is, hold the baby in a semi-recumbent position. If the mother's milk is too sufficient and the pressure is too high, the baby's head can be lowered slightly. This can avoid breastfeeding or swallowing. Eustachian tube causes acute otitis media.

Second, otitis media is the most common cause of hearing loss. For example, acute otitis media is usually infected by the eustachian tube. Usually, when the cold is caught, the nasal mucosa becomes inflamed, and the active bacteria will enter the middle ear directly from the nasopharynx opening of the nasopharynx, causing inflammation of the middle ear mucosa. This is particularly the case.

Because the eustachian tube is narrow, curved and long in adults, the opposite is true in infants and young children. The eustachian tube is relatively thick and horizontal, so bacteria in the nasal cavity and nasopharynx can easily invade, causing acute otitis media and even acute suppurative otitis media and affecting hearing. .

There is also a non-purulent otitis media called secretory otitis media, which is also an increasingly common disease.

Generally, it occurs more frequently in the winter and spring seasons. It is characterized by the accumulation of fluid in the middle ear cavity. At present, most people think that this disease is related to eustachian tube dysfunction, the body's immune function, and upper respiratory infections. Children with this disease have Suddenly appeared after a cold.

Some occur unconsciously, often with earplugs and hearing loss as the main manifestations. A small number of children report minor earaches, and most of them are manifested as sluggishness, misunderstanding or inattention.

Turning the volume of the TV set too high and the academic performance falling, etc. Because of the atypical clinical symptoms, it is easy to be ignored by parents, which causes children's hearing loss to varying degrees or accompanied lifelong.

Third, the middle ear is often threatened by "left and right neighbors", such as nose and pharynx diseases, including sinusitis, tonsillitis, proliferative adenitis, etc., often complicated by otitis media, so in order to protect the health of the middle ear, you must also Pay attention to correct this type of disease.

There are many clinical cases of this kind. After removing the children's hypertrophic and recurrent tonsils, not only the chance of catching a cold is reduced, but also the original recurrent otitis media is cured.

Fourth, many drugs are very toxic to the ear. Long-term use or a large amount of use at one time, or sick children are highly sensitive to this drug can cause hearing disorders.
