Is there any difference between neurological deafness and deafness?
Nervous deafness refers to a disease that occurs in the auditory nerve of the inner ear and the auditory center of the brain, causing hearing loss or even hearing loss. It is often accompanied by tinnitus, and neurological tinnitus is mainly caused by the auditory system. If there is a disorder in the sensorineural nerve part, tinnitus will usually occur when there is a problem with the inner ear receptors, and the tinnitus will respond to high-frequency products or piercing screams.
Deafness caused by damage to the inner ear hair cells, conductive nerves and central nervous system is neurological deafness, which may be caused by genetics, drugs, viruses, aging of the hearing organ, trauma and other reasons.
Deafness is divided into conductive deafness, nerve deafness and mixed deafness. Mixed deafness includes both conductive deafness and nerve deafness. Conductive hearing loss mostly refers to the obstruction of sound conduction between the external auditory canal and the inner ear. It is often caused by cerumen embolism, otitis media, interruption of the ossicular chain, otosclerosis, etc. Hearing can be improved through surgery. Nerve deafness is caused by damage to the hair cells in the inner ear. It can be caused by drug poisoning such as streptomycin, or by viruses and toxins that invade the inner ear. Treatment is relatively difficult, and symptomatic treatments such as nerve nutrition and blood vessel dilation can be given. Sensorineural deafness and mixed deafness can be diagnosed through electrical audiometry, acoustic impedance and other means, and timely treatment can be given.
If the hearing loss is within the range that a hearing aid can intervene, then a purely conductive hearing loss hearing aid has the best intervention effect, because the hair cells in the cochlea and the nerves behind the fossa are both There is no damage. As long as the sound is compensated, the speech resolution is generally very good. The second is mixed hearing loss. The worst hearing aid effect is sensorineural hearing loss. This kind of customer who wears a hearing aid often shows that he can hear the sound but still cannot hear clearly what is said sometimes. This is Because the hearing hair cells in the cochlea and the auditory nerve behind the socket are damaged, the hearing aid simply does not increase the volume, but it still cannot solve the problem of the auditory nerve. This kind of customer needs to wear the hearing aid for a long time and do more speech rehabilitation training. Slowly Improve the hearing sensitivity of the auditory nerve, whichIn this way, you can hear better and better. The auditory nerve needs to be exercised by listening to more sounds. Currently, there is no effective medical treatment. Hearing aid fitting is the only intervention method that does not require surgery.
