What causes sudden deafness, and what causes sudden deafness?

The cause of sudden deafness is not clear, but it may be related to the following factors: viral infection About 1 5 1 3 patients have a history of upper respiratory tract infection within one month before the onset of the disease, and the causative viruses include mumps virus, influenza virus, coxsackie virus, adenovirus, rubella virus, etc., among which mumps virus is the most important gener. The virus can cause non-purulent otitis media, which then invades the inner ear to cause sudden deafness, or directly to cochlear neurons to cause sudden deafness.

Blood flow disorders Some cases have vasospasm and thrombosis, indicating that blood flow disorders are also one of the important causes of sudden deafness. Functional changes in the inner ear Some patients with sudden deafness resolve spontaneously, so it may be due to a functional response to the inner ear. Others Sudden deafness can be caused by high mental stress, overexcitement, work pressure, overwork, violent coughing, sneezing, pinching the nose and puffing the air.

Too tired, too stressed, etc., will cause sudden deafness!

Sudden hearing loss, usually not too stressed.

Because local or systemic factors can cause sudden deafness, inner ear microcirculation lesions and specific viral infections are the most important causes of sudden deafness**. In addition, immune factors such as autoimmune diseases and some drugs with ototoxicity may also cause sudden deafness.

1.Sudden deafness of the low-frequency descending and ascending type: caused by water accumulation in the earmold;

2.High-frequency descending type: caused by microvascular spasm or hematospasm;

3.Usual sudden deafness or conductive sudden deafness: caused by vascular embolism, endometrial artery embolism, and vasospasm due to inner ear ischemia.

The pathogenesis and pathogenesis of sudden deafness are not clear, but it is mostly believed to be related to viral infections, neoplastic lesions, autoimmune diseases, drug poisoning, inner ear ischemia and other factors. Psychiatric and psychological factors are considered to be common triggers.

Essential**. Viral infections.

Cochlea, meninges, and auditory neuropathy caused by viral infections can cause damage to the auditory nerve and cause hearing loss.

Vascular disease.

For example, small embolic foci in the brain, hypercoagulation state, etc., can cause insufficient blood supply to the inner ear, resulting in hearing loss.

Neoplastic diseases.

Patients with acoustic neuroma and intracranial tumors may have sudden deafness as the primary symptom, which needs to be ruled out after imaging examination.

Drug intoxication. Taking drugs with ototoxicity such as aminoglycoside antibiotics, cisplatin, diuretic acid, quinine, etc., can lead to hearing loss.

Immune diseases.

Autoimmune diseases such as systemic lupus erythematosus and arteritis multinodosum can also cause sudden hearing loss.

Ear diseases. Patients with ear lesions such as great vestibular aqueduct syndrome, Meniere's disease, and ruptured window membranes can also have sudden hearing loss.

The causes of sudden deafness mainly include the following aspects:

First, the brunt is the vascular factor, whether it is your blood lipids, blood sugar, or even low blood pressure, high blood pressure, low blood pressure, because the brain is underperfused or too much can lead to a disorder of blood supply to our inner ear. Because the inner ear organ is a middle and last branch of the blood supply to our brain, it is very small and very fragile, if the blood circulation of our major arteries is not good, the arteries of our inner ear are very easily affected and affected. So it first of all** inner ear circulation is called the labyrinth artery.

This is a very small terminal branch of our brain branch, and if there is a problem with its blood**, it can produce this sudden hearing loss in our inner ear, which is the most common cause. Then there are some other diseases that are water and ion channel metabolism, the inner ear is a water labyrinth surrounded by bones, for example, our inner ear is divided into sodium ions and potassium ion concentrations are different, if the diseases that affect the metabolism of sodium and potassium ions will also affect our sudden deafness, and there are also some such as our hereditary congenital hereditary diseases, resulting in deafness will also manifest as a sudden hearing loss, and then followed by some space-occupying lesions. A lesion of the auditory nerve was grown, and so on.

This can cause our sudden hearing loss, sudden deafness susceptible people or most likely suffer from some cerebrovascular diseases, basic people are the most common, and then the survey of the Chinese population found that our median age is 41 years old, or work pressure closely related to work pressure and rest fatigue, often stay up late black and white upside down people, is also our high incidence group.

Clause.

1. Viral infection, it may be that the virus damages the auditory nerve. Clause.

2. Inner ear circulatory disorders, most of these patients are seen in middle-aged and elderly patients, and there is no history of colds.

There are many causes of sudden deafness, such as infection, poisoning and ischemia, which require relevant laboratory tests to be identified. The window period of the disease is very short, and once it is missed, there is almost no effect.

There are many causes of sudden deafness, the main ones are:

First, the age factor, due to the increase of age, the function of various organs of the body will gradually weaken, and the same is true for the hearing organs.

Second, the pressure is increasing, and the pressure of rapid social development is also increasing.

Third, the impact of noise, noise is an important aspect of deafness. If you work and live in a high-decibel noise environment for a long time, the chance of sudden deafness increases.

Fourth, genetic factors, the average person's deafness is caused by genetic factors, although they may hear the outside world at the beginning, most people will lose their hearing in the later stage.

1. Mainly ear diseases, such as external ear diseases: otitis externa, cerumen embolism, foreign body of the outer ear, etc., acute and chronic otitis media, tympanic membrane perforation, otosclerosis, Meniere's syndrome of the inner ear, acoustic neuroma, can cause sudden deafness.

2. Vascular diseases can also cause sudden deafness, such as jugular spheroid tumors, dilation of small blood vessels in the ear, vascular malformations, hemangiomas, etc., sudden deafness from veins is mostly noisy, and sudden deafness from arteries is consistent with the pulse pulsation.

3. Some other systemic diseases can also cause sudden deafness: autonomic disorders, cerebral blood supply deficiency, pre-stroke, hypertension, hypotension, anemia, diabetes, and malnutrition.

4. In addition, excessive use of drugs that have toxic effects on the ear, such as gentamicin, streptomycin or kanamycin, etc., can also cause sudden deafness and hearing loss, and sudden deafness appears earlier than hearing loss.

5. Excessive fatigue, lack of sleep, and excessive emotional tension can also lead to the occurrence of sudden deafness.

6. Noise: Violent sound and long-term noise exposure can lead to hearing loss and sudden deafness. People working in high-intensity noise environments should pay attention to noise protection, such as reducing noise sources or wearing protective earmuffs and earplugs.

Also, be careful not to use Walkman headphones in noisy environments for long periods of time and at loud volumes.

7. Bad habits: Caffeine and alcohol can often aggravate sudden deafness; Smoking can reduce blood oxygen, and the inner ear hair cells are extremely sensitive to oxygen, so lack of oxygen will cause damage to the hair cells, so it is necessary to pay attention to changing bad habits.

The above is about the introduction of what is the cause of sudden deafness, I hope the above introduction can be helpful to everyone, and we must choose a regular hospital and professional method when carrying out sudden deafness.

Sudden deafness may be caused by congenital genetic factors, or it may be caused by trauma to the ear, especially the auditory nervous system, which may also lead to sudden deafness.

There are many kinds, and you have to go to the hospital for check-up for specific situations!

It may be related to the sudden increase in pressure, and sometimes the sudden increase in pressure will lead to a sudden dragon, which should be treated in time.

It has a lot to do with the environment in which you usually live, so you should go to the hospital immediately for a check-up when such a small illness occurs, or it may be a viral infection or you have drunk a lot of medicine.

It may be because of recent stress, poor sleep, heavy volume in the ears, or hard blows to the ears.
