What causes 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.

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.

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.

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.

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.

**。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.

Acoustic neuroma. Patients with intracranial tumors may have sudden deafness as the primary symptom and need to be ruled out after imaging examination.

Drug intoxication. Taking drugs with ototoxicity such as aminoglycoside antibiotics, cisplatin.

Diuretic acid, quinine.

etc., which can lead to hearing loss.

Immune diseases.

Systemic lupus erythematosus.

Autoimmune diseases, such as arteritis nodos, can also cause sudden hearing loss.

Ear diseases. Great vestibular aqueduct syndrome, Meniere's disease.

Patients with ear lesions, such as ruptured window membranes, can also have sudden hearing loss.

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