When we talk to people, many of them ask about the term “neurological deafness”, and they are very nervous about this term, as if neurological deafness cannot be treated. In fact, most of this incorrect information is caused by inaccurate reports on the Internet, just like the so-called “neurological tinnitus”, the existence of which is actually not reasonable, but just over-exaggerated by some people for the sake of profit. Deafness or hearing loss, in layman’s terms, means that people who used to listen to others normally, now have some difficulty hearing and are stuffy in the ears. Hearing loss is classified as conductive deafness, sensorineural deafness and neurological deafness depending on the part of the hearing system affected by the disease. Conductive deafness can be caused by affecting the section from the external ear canal, eardrum, and auditory chain, including birth with closed external ear canal, earwax blocking the external ear canal, perforated eardrum, damaged auditory chain, secretory otitis media, otosclerosis, etc. Some of these deafness can be relieved by themselves as the disease gets better, and some can be improved by surgical or non-surgical means. Sensorineural deafness is damage to our cochlea, which is the transducer of sound signals into nerve electrical signals, and can cause deafness when the auditory nerve is normal. This type of deafness includes age-related deafness, drug-related deafness, noise-related deafness, Meniere’s disease, idiopathic sudden deafness, and congenital inner ear malformations (enlarged vestibular aqueduct syndrome). These deafnesses can also be improved by active treatment or by hearing aids or cochlear implants. Neurological deafness is deafness caused by damage to the auditory nerve to the auditory center, such as auditory neuroma, auditory neuropathy, etc. Most of this category can also be improved with treatment, but it is more difficult to treat, and this part of the cause is only a very small part of deafness. The concept of sensorineural deafness has emerged because it is sometimes difficult to distinguish between sensorineural deafness and neural deafness.
