Causes of deafness.
There are many causes of deafness. Hereditary deafness accounts for 50% of all deaf patients, and most of them are difficult to treat sensorineural deafness, which often seriously affects the effectiveness of rehabilitation training for deaf children if not detected early.
Drugs
Gentamicin is the main drug that causes toxic deafness and damages the vestibule and cochlea of the ear, and its use in children can cause irreversible hearing loss. Also streptomycin, kanamycin, diuretics, quinine, chloroquine, birth control pills, and heavy metal preparations are ototoxic drugs and should be used with caution.
Noise
Prolonged, excessive noise can have adverse effects on the central nervous system, especially damage to the auditory organs, leading to neurological deafness.
Infections and diseases Epidemic encephalomyelitis, measles, mumps, rubella, colds and other diseases can cause degeneration and atrophy or inflammation and lysis of ganglion cells. They may also invade the auditory nerve trunk, causing it to become inflamed or be compressed by the scar left by the surrounding inflammation, sometimes causing edema and even lysis of cells in the nucleus of the auditory nerve and leading to deafness.
Trauma
Trauma that perforates the tympanic membrane can cause conductive deafness; cranial trauma, inner ear damage, sudden shock or sudden change in air pressure can cause neurogenic deafness.
Mental and Emotional Mental stress, excessive stress and emotional stress can cause sudden deafness due to short-term hearing loss.
Prevention of deafness.
Prevention of deafness should start with yourself, scientific ear care and hearing protection.
① Maintain a good mental state. Take an active part in social activities and keep optimistic and unhurried mood;
②Create good dietary habits. Adjust the diet structure, eat more food rich in zinc, iron and calcium, avoid long-term consumption of high-salt, high-fat and low-fiber foods, avoid overeating, and quit smoking and drinking;
③Caution or prohibit the use of drugs that have damage to the auditory nerve. The use of drugs to strictly grasp the indications. Aminoglycoside antibiotics are one of the ototoxic drugs with the most cochlear damage. Avoiding the abuse of these antibiotics will be an important measure to reduce drug-related deafness;
④ Stay away from noise. Avoid contact with noise. You should not listen to the radio for too long and the volume should not be too high;
⑤ Massage the ear frequently. Massage the auricle, pinch the ear, and also massage the Fengchi point in the recesses of the hairline on both sides of the back of the neck, which can promote blood circulation in the inner ear and play the role of waking up the brain and ear;
(6) Active treatment of hypertension, hyperlipidemia, cerebral arteriosclerosis and diabetes is very important to prevent microcirculation disorders and slow down the rate of hearing loss in the elderly.
Treatment of deafness.
Hearing aids: Most moderate deafness can be compensated with hearing aids;
Vibratory bridges: For moderate to severe conductive, mixed and sensorineural deafness, vibratory bridges can help to re-establish hearing;
Cochlear implants: For severe and profound sensorineural deafness, cochlear implants are currently the only effective way to rebuild hearing.
