What Is Nerve Deafness?

Any structural or dysfunction in the sound transmission, sensory, or comprehensive parts of the human hearing system can be manifested as hearing loss to varying degrees, with lighter hearing and severe hearing loss. Hearing loss caused by impaired sound perception and nerve impulse transmission caused by impaired spiral hair cells, auditory nerves, auditory conduction pathways, or neurons at all levels is collectively referred to as sensorineural deafness.

Basic Information

English name

nerve deafness

Visiting department

ENT

Common causes

Ototoxic drugs, trauma, congenital, viral infection, noise, etc.

Hearing loss, hearing loss

no

Clinical manifestations of neurogenic hearing loss

Congenital deafness

Point out hearing impairments that existed at or shortly after birth.

Hereditary deafness

Refers to sensorineural hearing loss caused by genetic or chromosomal abnormalities.

3. Non-hereditary deafness

Early pregnancy mothers suffer from viral infectious diseases such as rubella, mumps, and influenza.

4. Senile deafness

It is the performance of the human aging process in the auditory organs. It is mainly characterized by bilateral symmetrical deafness that is slowly performed from high frequency to speech frequency, which can be accompanied by high frequency tinnitus, and the speech recognition rate is not proportional to pure tone audiometry.

5. Infectious deafness

Refers to sensorineural hearing loss caused by or complicated by various acute and chronic infectious diseases. There are mainly epidemic encephalomyelitis, scarlet fever, diphtheria, mumps and so on.

6. Deafness caused by systemic systemic diseases

The most common are hypertension and arteriosclerosis. These diseases cause blood supply disorders in the inner ear, increased blood viscosity, and disturbances in the lipid metabolism of the inner ear that cause hearing changes. Others include diabetes, nephritis, hypothyroidism, and leukemia.

7. Ototoxic deafness

Deafness caused by ingestion of certain drugs or long-term exposure to certain chemicals. Incidence has increased in recent years. Common drugs include streptomycin, kanamycin, gentamicin, etc. These drugs first damage the inner ear vascular veins when they enter the inner ear, the blood-labyrinth barrier is damaged, and the endolymphatic sac is damaged, and auditory and vestibular sensory cells occur. Degenerative changes cause hearing loss. Deafness is bilaterally symmetrical, and it develops from high frequency to middle and low frequency.

8. Traumatic deafness

Head trauma, fracture of the temporal bone, excessive diving speed, explosion, etc. can cause damage to the inner ear, and loss of hearing due to labyrinth shock.

9. Idiopathic deafness

Refers to severe sensorineural hearing loss that suddenly occurs without obvious cause. At present, the occurrence of this disease is related to inner ear blood supply disorders, viral infections or rupture of round window membrane and vestibular membrane. Most of them are monotonic, with tinnitus first, and some patients have Accompanied by dizziness, nausea, vomiting, and heavy numbness around the ears, most of the hearing damage is severe. A few patients can heal on their own, and most patients cannot achieve complete recovery.

10. Autoimmune deafness

It is a symptom of asymmetry, volatility, and progressive hearing loss that occurs frequently on both sides of young adults at the same time or successively, and is often accompanied by dizziness.

Diagnosis of neurological deafness

Detailed medical history, clinical manifestations, strict audiology, vestibular function, and eustachian tube examination, necessary imaging and whole body examination are the basis of diagnosis and differential diagnosis, and objective comprehensive analysis is the premise of diagnosis.

Neurodeafness Treatment

Drug treatment

While ruling out or treating the primary disease, use drugs that can dilate the inner ear blood vessels as early as possible to reduce blood viscosity and dissolve small thrombus, glucocorticoids, B vitamins, and energy mixtures. Antiviral and antiviral drugs can be applied if necessary Bacterial drugs.

Hearing aid

It is a loudspeaker that helps the deaf to hear sound. Those with average hearing loss between 35 and 80 dB can be used, and hearing is best at around 60 dB.

3. Cochlear implant

Also known as the electronic cochlea, it is a good tool to help the severely deaf to gain hearing and obtain or maintain speech function.

Neurodeafness prevention

1. Eliminate the marriage of close relatives, vigorously promote hearing screening for newborns, actively prevent and treat diseases during pregnancy, and reduce birth injuries.

2. Improve living standards, prevent and treat infectious diseases, actively treat systemic diseases such as hypertension and diabetes, and slow down the hearing aging process.

3. Strictly grasp the indications for the application of ototoxic drugs, and reduce the dosage and course of treatment as much as possible. Those who are found to be poisoned should stop treatment as soon as possible.

4. Avoid craniocerebral injury, minimize the contact with noise and other harmful factors, quit smoking and alcohol, and strengthen personal protection concepts and measures.
