What can trigger sudden deafness?

The ear is an important organ of the human body, and if you do not pay attention to protecting your ears, it is easy to cause deafness. Sudden deafness is also a type of deafness, and this symptom is sudden, a type of deafness of unknown cause. Sudden deafness usually repairs on its own, and the repair time varies depending on the individual's situation, so what are the factors that may cause sudden deafness?

1. Emotional wave factors

Frequent emotional agitation, irritability, and upward rush to the green hole, which can easily lead to sudden deafness. When a person's emotions are too excited or irritable and angry, the sympathetic nerves in the body lose their normal function or become disordered, affecting the blood supply in the ear, aggravating the blood supply disorder, and thus inducing sudden deafness.

2. Loud noise

Loud noise is the most harmful to hearing, and hearing will gradually decline after working and living in such an environment for a long time. Usually most of these people are workers or production workshop workers, who work in such an environment for a long time, do not pay attention to adjustment, do not pay attention to rest, and the noise is easy to take away the hearing, and eventually cause sudden deafness.

3. Mental pressure

Mental stress is also a major factor in hearing loss, and it is usually more common for people over the age of 40 to suffer from sudden deafness caused by mental stress. Due to excessive mental pressure, strong competitive psychology, long-term high tension, long-term fatigue without rest, it is easy to cause sudden deafness.

4. Viral infection

Viral infection will have a certain impact on the red blood cells and hearing of the blood vessels in the ear, usually viral infection is more common in patients with colds, when the virus invades the ear and red blood cells, or platelets affinity coagulate into a clump, thereby blocking the blood vessels of the inner ear, causing sudden deafness.

Sudden deafness is caused by many factors, sudden deafness must be targeted, in order to achieve better efficacy, once the patient has sudden deafness, should go to the hospital in time to understand the symptoms. In order to avoid the occurrence of sudden deafness, try to avoid damage to the ears from the outside world, develop good living habits, and maintain a good mood.

For example, if you often wear headphones, and the volume inside the headphones is particularly high, you may suddenly become deaf due to high blood pressure and high blood lipids, and you may be infected or affected by viruses.

These factors are, being affected by the outside world, excessive noise, damage to the eardrum, damage to the ear canal, and fungal infections, all of which can lead to deafness.

Environmental reasons, reasons for too strong decibels, causes of ear inflammation, genetic reasons, hereditary reasons, can all cause sudden deafness.

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.

Sudden deafness is generally not very clear, and about 90% of sudden deafness is not very clear. It is generally believed that sudden deafness and embolism or spasm of the microcirculation vessels in the inner ear lead to insufficient blood and oxygen supply to the inner ear, resulting in deafness. The specific reason for this situation is generally not clear, but **need to use hormone drugs first**, such as prednisone, the usual dose is 1mg kg, and the maximum dose per day can be used to 60mg, usually for 1-2 weeks, and generally can achieve a better effect.

About 70% of sudden deafness can have a relatively good recovery, but the earlier the sudden deafness, the better, and the delay sometimes tends to be ineffective.

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; Smoke can cause blood oxygen to drop, 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 cause of sudden deafness is unknown. But the general cause is due to several triggers: the first.

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. Clause.

3. Tumors of the auditory nerve, as well as pathological reactions, may also have some triggers related to wind, cold, mood swings, or anger before the onset of the disease or underlying cerebrovascular disease. Therefore, the specific cause of sudden deafness is not clear, but there are two major causes in general: viral infection and inner ear circulatory disorder.

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.

Sudden hearing loss is sudden, unexplained sensorineural hearing loss. The onset of patients with sudden deafness is often not clear, and some patients may have some predisposing factors, including recent frequent fatigue and staying up late, upper respiratory tract infection, mental and emotional stress and anxiety. Various viral infections that invade the nerves and disorders of blood supply and circulation to the inner ear caused by various factors are possible causes of sudden deafness.

The typical symptom of sudden hearing loss is that they feel that their hearing loss occurs suddenly, and some patients with hearing loss that is not severe only have a simple sudden feeling of ear tightness or simple symptoms of tinnitus. Some patients also experience dizziness and vomiting. Once the diagnosis is clear through the examination, it is necessary to carry out timely and sufficient ** to strive for the best ** effect.

The cause is divided into two aspects, one is called idiopathic sudden deafness, which generally refers to primary, and the other is spontaneous. Primary deafness, also known as idiopathic deafness, is unknown, but through clinical cases and physician data research, it has been found that it may be related to viral infection and inner ear blood circulation disorders. Viral infections, such as those with a history of upper respiratory tract infection and a history of herpes virus infection, can be asked before diagnosing sudden deafness.

Blood circulation disorder, the labyrinth artery of the inner ear is a terminal artery, lack of collateral circulation, if the blood viscosity in the blood circulation is too high, the blood flow will slow down, easy to form thrombosis and blockage, which will lead to blood supply disorders in the inner ear and sudden deafness. For secondary, sudden hearing loss, it is usually due to congenital genetic disorders secondary to other diseases, such as diabetes, high blood pressure, and other inner ear disorders. The above content is for reference only, please take a doctor for specific medication.

There are many reasons for sudden deafness, mainly the following: 1. Viral infection, nerve damage in the ear, and insufficient blood in the ear; 2. Drinking too much alcohol makes blood vessels spasm; 3. Excessive mood swings, or staying up late will reduce blood**; 4. Seasonal changes, especially in the north, the seasonal change is especially obvious, and the temperature difference is large, and the blood vessels constrict to form spasms; 5. Noise is also an important cause of sudden deafness.

Sudden deafness.

It is a sudden sensorineural hearing loss, which is mainly manifested by sudden hearing loss on one side, accompanied by tinnitus and earplug sensation. There are several theories about the mechanism of occurrence in the academic world, such as circulatory disorders, viruses, infections, and immune problems, which are mainly related to circulatory ischemia of the inner ear, hypoxia, vasospasm, and even thrombosis. There are many main triggers, such as young people like to stay up all night and stay up late, and some people have sleep disorders and stress and tension.

Sudden deafness is an emergency of the ear, characterized by sudden rapid hearing loss, generally monocral, patients may have some predisposing factors, including upper respiratory tract infection, fatigue and staying up late, poor mental and emotional conditions, high work pressure, etc., and may also cause ear microcirculation disorders and insufficient blood supply due to factors such as terminal blood vessel blockage, and patients may also be accompanied by tinnitus, dizziness and vomiting symptoms. Once the sudden deafness is diagnosed by examination, it needs to be treated in time**, and some patients need to be hospitalized**, and the examination is further improved, and the timeliness of ** is of great significance to the recovery of the disease.

In addition to finding a lot of Western medicine claims on the Internet, different ages and genders will have different influences. Other friends have said a lot, and I will add one, for example, there is a person in the family who often nagged and tortured this person, and he did not want to listen to it very much; Or often hearing bad news that breaks him, can lead to sudden deafness. These are all psychological deafness, and the subconscious mind does not want to hear these bad news or nagging that break him, a kind of self-preservation reaction of the body.

Common cases of sudden deafness** include vascular factors, viral infections, immune factors, endolymphatic hydrops, infectious diseases, or tumors.

The theory of sudden deafness is unknown, and many agens may cause sudden deafness, and the main theories that have been widely recognized are viral infection, circulatory disorders, autoimmunity, and membrane labyrinth rupture.

Clinical presentation. 1.Deafness.

Most of them are unilateral deafness, and there is often no aura before the onset of the disease, and a few patients have a history of mild cold, fatigue, or emotional agitation. Deafness occurs suddenly, and the patient's hearing usually drops to its lowest point within minutes or hours, and in a few patients, the hearing loss reaches the lowest point within 3 days.

2.Tinnitus. It can be the first symptom, and most patients develop tinnitus when they are deaf, but tinnitus can also occur after deafness. After menstruation, most patients can improve their hearing, but tinnitus can be long-lasting.

3.Vertigo. Some patients may be accompanied by varying degrees of vertigo, mostly rotational vertigo, accompanied by nausea and vomiting. May occur at the same time as or around the onset of deafness.

4.Other. A small number of patients may have a feeling of ear congestion, pressure, or numbness.

Examine. 1.Physical examination.

Examination of the tympanic membrane showed no obvious lesions. The tuning fork test suggests sensorineural hearing loss.

2.INVESTIGATIONS.

1) Hearing examination pure tone audiometry: The hearing curve generally shows moderate to severe sensorineural hearing loss, mostly of which is of high-frequency decline. Acoustic impedance detection: normal tympanic pressure curve. Otoacoustic emissions and electrocochlear imaging show cochlear lesions.

2) Vestibular function examination is generally performed during the period of vertigo remission, and the alternating hot and cold test combined with electronystagmography is commonly used, and the test results may be normal, decreased or completely disappeared.

3) Imaging examination of temporal bone CT and MR of the internal auditory canal showed that there were no obvious organic lesions in the internal auditory canal and cranium.
