What causes deafness? What causes deafness?

Lack of sleep, staying up late for a long time, or making too much noise, wearing headphones too loudly, drug allergies, or external injuries can all cause deafness.

Both external and internal causes can cause deafness, external causes such as noise pollution, toxic substances, etc., internal causes are diseases of the body itself, in addition to congenital diseases such as cerebral ischemia and hypoxia, cerebral nervous system diseases, inner ear inflammation, trauma, etc.

There are many causes of deafness, such as mechanical deafness, diseased deafness, and toxic deafness. Mechanical deafness has severe bath noises that vibrate the eardrum, light wave side radiation irritates the auditory nerve, severe allergies cause deafness, drug-induced deafness, etc., and the causes of deafness are explained in ominous detail.

There are many causes of deafness, but the first thing to know is whether it is sudden or progressive.

Sudden deafness is a sudden onset of hearing loss. At this time, it is necessary to go to the hospital in time to carry out **, do not exceed its best ** time. Infusions can be taken within a month to relieve the symptoms of sudden deafness by nourishing nerves, thrombolysis, and vasodilation, including hormones.

If it is a gradual decline in hearing, Chinese medicine calls it gradual deafness. This deafness is difficult to prevent. Therefore, if you want to alleviate this situation, you need to avoid noise exposure, avoid exposure to loud sounds, and contact with noise for a long time, all of which need to be reduced.

**There are no particularly good ways to wear hearing aids, only hearing loss to a certain extent.

There are so many causes of deafness that it can be said that any part of the external ear, middle ear, inner ear, auditory nerve, and auditory center of the brain, which constitutes sound, may cause hearing impairment, so it is necessary to actively avoid all the factors that cause lesions in this pathway.

It depends, there are so many reasons.

Deafness may be caused by lesions in any one or more of the outer ear, middle ear, cochlea, auditory nerve, auditory cortex.

After the sound wave conduction enters the external auditory canal and vibrates the tympanic membrane, it drives the ossicles in the middle ear, pushes the vestibular window and round window of the cochlea, causes the movement of lymphatic fluid, and excites the hair cells to produce action potential, which is transmitted through the auditory nerve to the auditory center of the cerebral cortex, and finally produces hearing. Lesions in any one or more parts of the conduction pathway will affect the production of hearing, resulting in deafness, mainly due to the following:

1) Diseases of the outer ear. Such as stenosis of the external auditory canal, cerumen embolism, boils and swelling of the external auditory canal, these diseases can cause the volume of the external auditory canal to decrease, hindering the conduction of sound.

2) Middle ear disease. Such as perforation of the eardrum, interruption of the ossicular chain, otitis media, middle ear deformity, etc.

3) Inner ear disease. Such as sudden deafness, Meniere's disease, noise deafness, large vestibular aqueduct syndrome, etc.

4) Postcochlear disease. That is, it refers to the lesions of the auditory pathway behind the cochlea, such as acoustic neuropathy, acoustic neuroma, auditory center processing disorder, etc.

Hello, the factors that cause deafness:

1 Noise: Noise is an important factor that directly causes hearing damage and is also an important cause of deafness. If you work or live in a high-decibel noise environment for a long time, the hearing cells will gradually be damaged. In the long run, tinnitus and hearing loss will occur.

2. Trauma: In people's daily life, some external injuries are ubiquitous, such as car accidents, direct injuries, violent vibrations, etc., which may cause damage to the tissues and organs in the ear.

3 Stress: The accumulation of excessive stress is an important reason for the sudden deafness of many people in today's society. Stress, fatigue and other conditions will cause the body's immunity to decrease, endocrine disorders, local blood vessel congestion, etc., which may cause local hypoxia and ischemia, and if it appears in the ear, it will affect the tissue function of the ear and affect hearing.

4 Drugs: Ototoxic drugs are an important factor in causing deafness, medical studies have shown that drugs that can cause deafness are common aminoglycoside antibiotics, as well as some antineoplastic drugs, diuretics, anti-inflammatory analgesics, etc.

5 Some diseases of the ear, such as otitis media and acoustic neuroma, are important causes of deafness or partial hearing loss.
