Why does sudden deafness happen! What causes sudden deafness?

You mean that the ear suddenly can't hear things, hearing is caused by the eardrum in the ear to receive the vibration of the air and transmitted to the brain by the ear god level for processing, sudden deafness, the possible cause is excessive psychological pressure or disease caused by the ear nerve problems can not convey information normally, and secondly, the eardrum damage caused by trauma will also make you unable to sense the sound of the outside world, you had better go to the hospital for a check-up to confirm what is wrong.

There are many causes of sudden deafness, and it is recommended that you go to the hospital for a check-up as soon as possible**! The longer the deafness is flare-up, the less likely it is to recover.

The four major cases of sudden deafness.

1. Vascular diseaseVascular disease is an important factor leading to sudden deafness. Due to predisposing factors such as cold, heat, fatigue, agitation, allergies and endocrine disorders, it causes human autonomic dysfunction, resulting in inner ear blood circulation disorders. Its pathological changes can be vasospasm, edema, hemorrhage, thrombosis and blood cell sticking, etc., which lead to blood stasis, insufficient blood supply to the inner ear, causing tissue edema, hypoxia, and then metabolic disorders, and finally damage the peripheral receptors of the inner ear, causing deafness.

2. Viral infectionViral infection is the most common cause of sudden deafness, and viral infection follows the following main routes:1Bloodstream infection:

Viral particles enter the inner ear blood circulation directly from the blood circulation, causing cochlear circulation disorders or endolymphalabyrinthitis. 2.Transmeningeal route:

The virus invades the perilymphatic space from the subarachnoid cavity through the cribriform plate at the floor of the internal auditory canal or through the cochlear tubule to cause perilymphatic labyrinthitis and thus cochlear symptoms appear after meningitis. Herpes zoster virus is the main cause of perilymphatic labyrinthitis. 3.

Trans-circular route: non-purulent otitis media caused by a virus, infection can invade the inner ear through a round window. 3. Some mild to moderate sudden deafness with or without vertigo, may be a different type of Meniere's disease.

Sudden deafness may also be the first symptom of Meniere's disease, which occurs in 5% of patients. A positive furosemide test for sudden deafness accounted for 27% (3 11 people). 4. Rupture of the road membrane and rupture of the labyrinth membrane refers to the rupture of the round window or oval window membrane of the inner ear combined with the rupture of the corchal membrane. Due to the rupture of the membrane, it causes symptoms such as sudden ** tone neural deafness, vertigo and tinnitus.

Sudden deafness is induced by sudden exertion or sudden changes in air pressure in the middle ear and intracranial pressure. We know that the main reasons for sudden deafness are these reasons, so we must pay attention to protecting our ears in our daily life and not let them be harmed, so as not to affect our life, work or study.

There are currently two main reasons for sudden deafness:

1. Viral infection: The virus has a strong affinity for the red blood cells and auditory nerve in the blood vessels of the inner ear, many patients have a history of cold before the onset of the disease, when the virus invades the inner ear, it has affinity with red blood cells and platelets, coagulates into a clump, blocks the blood vessels of the inner ear, and leads to the occurrence of sudden deafness. In addition, the virus has an affinity with the auditory nerve, which can cause congestion and edema of the auditory nerve, which is also the cause of sudden deafness.

2. Inner ear microcirculation disorder: when people are emotional or anxious, the secretion of adrenaline increases, which causes spasm of the arteriole blood vessels in the inner ear, and the blood flow in the small blood vessels is slow, resulting in the adhesion of red blood cells and platelets in the blood, and the occurrence of blood flow disorders, and the lack of oxygen supply to the inner ear leads to the occurrence of sudden deafness. Some elderly people, especially those with arteriosclerosis, are very prone to disordered blood circulation in the inner ear and sudden deafness caused by roller skating.

What causes sudden deafness.

The cause and pathogenesis of sudden deafness are not clear, and it is mostly thought to be related to viral infection.

Tumors in swollen and hungry hands, autoimmune diseases, and drug poisoning.

Factors such as inner ear ischemia are related. Psychiatric and psychological factors are considered to be common triggers.

The number of sudden deafness and sudden deafness is unknown internationally. However, several common causes are mainly an infectious factor, mainly bacterial or viral infection. Some patients have a history of colds before sudden deafness, that is, a history of upper respiratory tract infection, which is a common cause for him.

This is followed by a microcirculatory disorder in the cochlea of the ear, including spasm of a blood vessel. Some of these patients have pre-existing hypertension or even cardiovascular diseases. These causes can cause us to become suddenly deaf.

There are other reasons, such as immunity, some factors, including this, there are still some patients who have no cause at all, and it is possible to have this sudden deafness.

3. Some hand tremors are caused by cerebral ischemia and hypoxia, and drugs to invigorate blood should be given to improve hand tremors. 4. Essential tremor is caused by genetic factors, and Almar and propranolol can be given to improve the symptoms of hand tremor. 5. If it is hand tremor caused by Parkinson's disease, levodopa should be given for **.

It can be caused by a variety of different conditions**, and it is thought to be related to a disorder of blood supply to the inner ear or a viral infection. The rupture of the round window membrane and vestibular membrane was once thought to be one of the causative causes, but the rupture of the window membrane peripheral lymphatic fistula is now regarded as a major silent disease. Inner ear blood supply disorders cause microembolism of the cerebellum due to embolization of the anterior inferior or posterior inferior cerebellar artery, which can present with symptoms similar to labyrinthitis.

Degeneration of spiral sensory structures due to hypoxia due to vasospasm, embolism, thrombosis, vascular pressure, intravascular stenosis, hemorrhage, increased blood coagulability, fluctuating arterial blood pressure, and other vascular disorders. Viral infection may be caused by the virus entering the inner ear dust mimic sensitive blood vessels, causing vascular endometrial edema, capillary epithelium swelling and hyperplasia, narrowing of the lumen, and slow blood flow. In addition, the virus is also compatible with red blood cells, that is, the drug in the systemic circulation has been drained and attracted, and its surface charge changes and is easy to coagulate, causing blood to stagnate.

This causes the vestibular membrane and vascular striae to atrophy, and the hair cells to act on the auditory branch receptors of the inner ear, or necrosis.

The sooner you find out, the better!

There are many reasons for sudden deafness, such as excessive pressure in life and study, long-term mental stress, excessive smoking and drinking, excessive fatigue, accidental injury, etc., once the sudden deafness is found, it is necessary to go to the hospital in time to talk about it, and the best time is 72 hours.

There are many causes of sudden deafness. Usually it can be caused by excessive stress, lack of rest and sleep, taking certain drugs by mistake, ear problems, cardiovascular and cerebrovascular diseases, etc. It is recommended that you go to a regular hospital for relevant examinations as soon as possible to avoid delaying your condition.

In the near future, you need to relax your mind and not have too much mental stress.

Sudden deafness occurs within 72 hours, and the only deafness that occurs suddenly is that the specific criterion is unexplained, and at two consecutive frequencies, such as more than 20 dB, it is called sudden deafness.

At present, many people are more concerned about sudden deafness, because the first is the incidence, and the current increase is relatively obvious, and the other is younger, which may be related to the whole rhythm of life and staying up late.

At present, the cause of sudden deafness is not very clear in many cases, although many theories believe that it may be related to a factor that is blood vessels, that is, the blood vessels suddenly constrict, and the blood supply in the skull is very, very fragile, especially tired, or in the case of infection, the reason for the constriction or blockage of this blood vessel.

The other is that many of them have some viral infections, just like many sudden deafness will be preceded by a history of upper respiratory tract infection, that is, there will be infections that will occur suddenly, but there are many other reasons.

The cause and pathogenesis of sudden deafness are still unclear, and 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.
