What are the main causes of sudden deafness?

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

2. Sudden deafness can also occur in vascular diseases, such as jugular spheroid tumor, 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 disorder, 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 occurs earlier than hearing loss.

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

Hello, fascinated hearing loss is a type of sensorineural hearing loss that occurs suddenly and of unknown cause. The general causes of sudden deafness include: 1. Viral infection is the most common cause of this disease; 2. Vascular lesions cause microcirculation disorders in the inner ear and cause sudden deafness; 3. Labyrinthine membrane rupture refers to the rupture of the round window or oval window membrane of the inner ear and the rupture of the cortile membrane.

Due to the rupture of the membrane, it causes symptoms such as sudden neurological deafness, vertigo and tinnitus.

Clinical manifestations include deafness, tinnitus, vertigo, nystagmus, etc. Patients should be hospitalized** if possible, on bed rest, and with limited water and salt intake.

Prevention and recuperation: 1. Recuperate with peace of mind and avoid exposure to noise or excessive sound; 2. Prevent colds; 3. Be careful not to overwork, do daily life, and eat a certain amount; 4. Be emotionally stable, avoid anger and ecstasy.

Only a small number of patients with sudden deafness can find the exact cause of the disease, and the vast majority of patients cannot be confirmed by examination. Most of the patients are physically tired or under excessive mental and emotional stress before the onset of the disease, and some patients are under unforewarning, usually in the autumn and winter when the weather becomes colder. At present, many possible pathogenic mechanisms have been proposed, including viral infection, poor inner ear perfusion, rupture of the inner ear lymphatic system, autoimmune diseases, etc., but most patients cannot find a specific cause.

Sudden deafness refers to deafness of unknown cause or for which the cause has not yet been identified, and once the cause of the disease is identified, it can no longer be diagnosed as sudden deafness, and it is only a symptom of the disease. The causes, pathologies, and physiological mechanisms of sudden hearing loss have not been fully elucidated, and both local and systemic factors can lead to sudden hearing loss. Common ** include vascular diseases, viral infections, autoimmune diseases, infectious diseases, and tumors.

Only 10% to 15% of patients with sudden deafness have a clear cause during the onset of the disease, and another 1 3 patients** are followed up, evaluated, speculated, or confirmed over a long period of time. It is generally believed that mental stress, stress, mood swings, irregular life, sleep disorders, etc. may be the main predisposing factors for sudden deafness.

There are many causes of sudden deafness, sudden deafness is more common in middle-aged and elderly people, it is severe sensory deafness that occurs in an instant, the general onset time is not more than 24 hours, the deafness reaches its peak, often the onset of one ear, occasionally both ears at the same time or successively, most of the patients can accurately say the time, place and situation of the disease after the onset of the disease.

There are currently two main reasons for sudden deafness:

1. Viral infection: The virus has a strong affinity for 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 older people, especially those with arteriosclerosis, are highly susceptible to inner ear blood circulation disorders that cause sudden deafness.

What causes sudden deafness.

Hello! Sudden deafness refers to the sudden onset of unexplained sensorineural hearing loss, which is mainly manifested as unilateral hearing loss, which can be accompanied by tinnitus, ear blockage, dizziness, nausea, vomiting, etc., and is one of the more common ear diseases. At present, there are several theories that everyone recognizes, mainly viral infection theory, circulatory disorder theory, autoimmune theory and membrane labyrinth rupture theory, etc., which have not been well confirmed.

This is closely related to the usual work and rest, staying up late, excessive stress, being in a noisy environment for a long time, wearing headphones for a long time, strong mood swings, improper medication, etc., to develop good living habits, eat a light and nutritious diet, stay away from the noise environment, and always have earplugs to protect the ears at any time. Let your ears rest every day, watch TV and play with your mobile phone reasonably**!

There are many reasons for this There are many reasons for staying up late, stress, noisy environment, wearing headphones for a long time, strong mood swings, and it is closely related to developing good living habits to have a good body.

It is a sudden, unexplained sensorineural hearing loss. Acute vascular occlusion and viral infections are thought to be common causes. Lesions may involve the spiral apparatus or even rupture of the vestibular membrane or cochlear membrane.

Deafness can manifest instantaneously, mostly unilaterally, and there are also diseases in both ears, accompanied by tinnitus, and some can be accompanied by vertigo.

The symptoms are one or both ears in a short period of time (within a few hours or a few days), the hearing drops suddenly, and in severe cases, it can be completely deaf, and can never recover, causing hearing disability. Patients with sudden deafness often have aura, such as sudden tinnitus, dizziness, or a feeling of stuffiness in the ears. If you have any of the above symptoms, you should pay special attention to your hearing problems.

Exposure to cold, heat, fatigue, agitation, allergies and endocrine disorders can all lead to disorders of inner ear circulation, resulting in insufficient blood supply to the inner ear and hearing loss. In addition, arteriosclerosis and thrombosis can also cause blood circulation disorders in the inner ear.

Viral infections that cause sudden deafness are common such as influenza, mumps, shingles, etc., and sometimes can cause sudden deafness even though there are no obvious symptoms such as general fever and headache.

Some metabolic disorders and hematologic diseases such as diabetes, hyperlipidemia, hypothyroidism, and increased serum viscosity can also cause sudden deafness.

There are three main manifestations of sudden deafness, the first is hearing loss, most of which occur in one ear, and the degree of deafness varies from severity to severity, and it is rare for people who are completely deaf. Secondly, patients often have a sense of blockage or fullness in the ear, and 70% of patients are accompanied by tinnitus, which mostly occurs at the same time as deafness, and the degree of tinnitus is generally severe, which mostly affects the patient's rest and sleep. Vertigo is another symptom of the disease, about 37%-68% of patients have this symptom, and severe vertigo may have nausea and vomiting.

A small number of patients may also have symptoms of upper respiratory tract infection, such as headache and low-grade fever.

There are many causes of sudden deafness, and the definition of sudden deafness is sudden hearing loss within 2-3 days, and the cause of the patient is relatively difficult to determine. It is now thought that the most common cause is a viral infection, secondary to fatigue, stress, or lack of sleep that leads to a decrease in immunity. Viral infection does not necessarily have cold symptoms, it can be directly manifested as hearing loss, it is an inflammatory manifestation, mainly through drugs**, can be taken orally or intravenously, or directly injected into the ear.

Sudden deafness is caused by a tumor growing on the auditory nerve, and there is a 10% chance that an acoustic neuroma will manifest as sudden deafness.

When sudden deafness is not effective in the drug**, it is necessary to do an MRI of the ear to determine whether there is an auditory nerve tumor. There is also a part of sudden deafness may be a manifestation of cerebral infarction, central ischemia or cerebral hemorrhage will also cause unilateral hearing loss, pay attention to whether the patient has limb movement disorders, limb sensory disorders, or whether there is coughing, hoarseness or other cranial nerve problems. If there are central symptoms, consider whether there is a cerebral infarction or cerebral hemorrhage, and then treat it accordingly.

1. According to the theory of viral infection, many patients will have a history of colds before the onset of the disease, or when the body's immunity is weakened such as fatigue and cold, and many virus results will be found to be positive in blood tests. 2. The theory of inner ear blood supply disorder is mainly due to the blockage of the only blood vessel due to thrombosis or embolism. At present, the treatment of sudden deafness is mainly based on drugs, and glucocorticoids are needed to improve the circulation of the inner ear and nutrition of nerves.

For those who do not respond well to medication** and do not improve their hearing for 3 months, they may choose to wear hearing aids.

Sudden hearing loss, including primary sudden hearing loss and secondary sudden hearing loss. They have some common symptoms between them, hearing loss, which is deafness. The deafness is caused by the lesion affecting the auditory nerve, and the position of the auditory nerve and the vestibular nerve is close, and the lesion will affect the vestibular nerve, causing symptoms of vertigo, resulting in nausea and vomiting.

Secondary sudden deafness may be a symptom of its primary disease, such as ischemia of the middle circulation of the skull and brain, leading to corresponding headaches. Other forms of Meniere's disease are accompanied by symptoms of Meniere's disease, and the vestibular nerve has symptoms of vestibular neurosis Zheng Jingjing, which is some of the symptoms caused by secondary sudden deafness.
