How does nerve induced tinnitus occur?

To understand the type of nervopathic tinnitus, you need to know what type of nervose tinnitus is. The cause of the disease is thought to be due to lesions or dysfunction of the cochlea, auditory nerve, and central auditory pathways.

First, the main **.

1. Sensory tinnitus: the most common, most of which are related to drug-induced ototoxic tinnitus and senile tinnitus.

2. Peripheral neurological tinnitus: **Unknown, it may be related to the degeneration of nerve fibers causing inter-fiber interaction, or the slowing down of nerve fiber transmission.

3. Central nervous system tinnitus: tumors, vascular abnormalities, local inflammation, multiple sclerosis, etc., can occur in patients who invade the auditory pathway.

2. Predisposing factors.

The disease can be precipitated by the following conditions:

1. Psychological factors and sleep disorders.

2. Poor ear use or occupational exposure, such as too loud earphones and too long wearing time, can also induce tinnitus.

3. Presbycusis occurs in the elderly with age.

4. Trauma to the head or ears.

5. Toxic hearing loss caused by taking drugs.

6. Cochlear lesions, tumors, Meniere's disease and otosclerosis.

What causes nerve-induced tinnitus?

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

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

Other systemic diseases can also cause tinnitus: autonomic disorders, cerebral blood supply deficiency, pre-stroke, hypertension, hypotension, anemia, diabetes, and malnutrition.

In addition, tinnitus and hearing loss can occur with excessive use of drugs that have toxic effects on the ear, such as gentamicin, streptomycin, or kanamycin, and tinnitus occurs earlier than hearing loss.

Excessive fatigue, lack of sleep, and emotional stress can also lead to tinnitus.

Noise: Loud noises and prolonged noise exposure can lead to hearing loss and tinnitus. 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.

Bad habits: Caffeine and alcohol can often worsen tinnitus symptoms; 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.

1.Some patients with neurological tinnitus are caused by the use of some toxic and overdose drugs, for example, many patients have tinnitus and hearing loss because of the use of gentamicin, streptomycin or kanamycin after a cold and fever**.

2.Many people do not pay attention to the maintenance of the body, which can also lead to neurological tinnitus, such as not paying attention to rest at ordinary times, so that the body is overtired, sleep time is unstable, and sleep is insufficient.

3.Bad habits: For example, some patients always wear headphones to listen to songs, which can easily lead to nerve damage and neurological tinnitus, and some patients like to drink, coffee, smoke, etc., which is also one of the bad genres, mainly caffeine and alcohol will aggravate tinnitus symptoms; Smoking causes the patient's blood oxygen to drop and damage the hair cells inside the ear, resulting in neurological tinnitus.

4.Diseases of the ear are also the causes of neurological tinnitus, common diseases of the outer ear include otitis externa, excessive earwax is not cleared in time, the external ear canal enters the foreign body, etc., when the human middle ear has acute and chronic inflammation or when the ear is picked, the tympanic membrane is perforated, the small blood vessels in the ear are dilated, and the acoustic neuroma and other problems can cause tinnitus.

Nervous tinnitus can be caused by damage to the cochlea caused by constant loud noises in the surrounding environment, or it can be caused by taking drugs that have toxic effects on the ears for a long time.

If it is caused by nervous tinnitus, symptoms such as tinnitus, hearing loss, and vertigo will mainly occur, and as the disease progresses further, it may induce complications such as sleep disorders and depression. Neurological tinnitus is mainly caused by lesions of nerve cells and nerve fibers in the inner ear. There are many causes of nerve cell and nerve fiber lesions, including high blood pressure, ear ischemia caused by diabetes, as well as ototoxic drugs, noise, etc., which can cause neurological tinnitus, and senile degeneration can also cause neurological tinnitus.

Then, there are many diseases that cause neurological tinnitus, including chronic purulent otitis media, cholesteatoma of the middle ear, malignant tumors of the middle ear, tympanogloma, etc., as well as acoustic neuroma, and tumors of the pontine cerebellum can cause neurological tinnitus, and our most common sudden deafness, Meniere's disease can also cause neurological tinnitus. If the damage is transient and the nerve cells are not seriously damaged, if it reaches a level where it can be recovered, the neurological tinnitus can heal on its own, and in other cases, it must be relieved.

There may be autonomic disorders, it is also possible that there are other factors that can cause autonomic disorders, resulting in neurological tinnitus, you had better go to the otolaryngology to see a doctor, or a neurology department.
