About 4.66 million people worldwide suffer from different types of hearing loss. Untreated hearing loss has a certain impact on communication, interpersonal relationships, physical and mental health, and even personal career.
I often have weak listeners asking, “Can you recover your hearing through surgery?”
Simply put: the situation.
Can sensorineural hearing loss be treated surgically?
Sensorineural hearing loss is arguably the most common hearing loss, and most of the adults with hearing impairment fall into this category.
There are many reasons for this type of hearing loss, such as age (senile hearing loss), sudden or sustained high-intensity noise (noisy hearing loss), disease and ear infections, head or ear trauma, and tumors. Take ototoxic drugs (drug-induced hearing loss).
Under normal circumstances, the inner ear hair cells are responsible for converting the sound collected by the outer ear and the middle ear into electrical impulses, which are then transmitted by the auditory nerve to the brain, which is then interpreted by the brain as an identifiable sound.
Sensorineural hearing loss means that the inner ear hair cells or the nerve pathway connecting the inner ear and the brain are damaged. Sensorineural hearing loss is a permanent hearing loss. At present, we cannot repair damaged hair cells by surgery. It is generally recommended to use hearing aids for hearing aid compensation.
In addition, for hearing loss that has little or no effect on some hearing aids, it is possible to surgically implant a cochlear implant, bypass the damaged part of the patient’s ear, directly stimulate the hair cells in the cochlea, and let people regain sound.
Children and adults with severe to very severe sensorineural hearing loss may consider restoring partial hearing by implanting a cochlear implant.
Unlike traditional hearing aids that amplify sound, the cochlear coil bypasses the damaged portion of the auditory system and directly stimulates the auditory nerve.
Usually, when the hearing aid compensation does not have much effect, the doctor will recommend the cochlear implant. Before the operation, the professional doctor of the professional hospital needs to make a comprehensive assessment of the hearing and health status of the hearing impaired person. Into the standard to perform surgery.
Cochlear implants are an invasive procedure, so doctors usually only recommend surgical advice to people with severe or higher hearing impairments who have little or no effect on hearing aids.

Can conductive hearing loss be treated surgically?
Conductive hearing loss refers to the presence of a lesion in the outer or middle ear so that the sound is obstructed before it reaches the inner ear.
This type of hearing loss may be temporary or permanent, depending on the cause of the disease. In some cases, medication or surgical intervention can restore hearing.
The velvet ear lists two common operations to help you understand.
1. Middle ear catheterization
Ear inflammation is high in children. According to the American Academy of Otorhinolaryngology Head and Neck Surgery, children have at least 5 secondary ear inflammation before the age of 1. Inflammation of the ear usually disappears on its own without causing permanent damage, but some children suffer from chronic otitis media, which causes hearing loss over time, poor academic performance, and behavioral or speech impairment.
Usually in this case, the doctor will recommend that the middle ear tube or pressure balance tube be placed in the ear through surgery to relieve the increased pressure of the tympanic membrane if the middle ear fluid cannot be discharged.
Short-term tubes usually fall off on their own during 6 to 18 months, while long-term tubes are placed for a longer period of time and require a professional otolaryngologist to remove them.
2. humerus resection
Just as atherosclerosis causes arteriosclerosis, otosclerosis refers to the appearance of abnormal hardening on the base of the middle ear tibial, resulting in hearing loss.
At present, the treatment of otosclerosis is mainly surgery, in which patella resection is a recognized treatment:
Partial or total removal of the abnormally hardened humerus, using the autologous residual humerus, or the bone or cartilage column of the other body, the artificial humerus made of various organic and inorganic materials, placed in the anvil bone bulge and vestibule Replace the cheekbones between the windows.
There are three main types of ear hardening:
Tibial sclerosis: Hardening spreads to the tibia and impedes its vibration, leading to conductive hearing loss, which can usually be cured by a sacral resection.
Cochlear sclerosis: Sclerotherapy invades the cochlea and causes permanent damage to the sensory hair cells or nerve pathways connecting the inner ear and the brain, causing sensorineural hearing loss. In this case, the patella resection is also ineffective.
Mixed otosclerosis: Both of these are combined with the development of the disease.
I hope that in the near future, we can have more ways to help the hearing impaired to hear better. However, for the time being, surgery can only improve some types of hearing loss. For most people with hearing impairment, the simplest and most effective way is to wear a hearing aid.
