Around 466 million people in the world suffer from different types of hearing loss. Untreated hearing loss has a certain impact on communication, interpersonal relationship, physical and mental health, and even personal career.

Often have weak listen friend to ask, “can you restore hearing through operation?”
< P style = "color:; font family: Arial, Verdana, sans serif;" >
To put it simply: points.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
There are some types of hearing loss, which can be recovered by ear surgery, but this only accounts for a small proportion! Next, Jinghao’s hearing is introduced according to different types of hearing loss.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
Can sensorineural hearing loss be treated surgically?
< P style = "color:; font family: Arial, Verdana, sans serif;" >
< P style = "color:; font family: Arial, Verdana, sans serif;" >
< P style = "color:; font family: Arial, Verdana, sans serif;" >
Sensorineural hearing loss is the most common hearing loss. Most of the adults with hearing impairment are in this situation.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
There are many reasons for this kind of hearing loss, such as age (old-age hearing loss), sudden or continuous high-intensity noise (noise hearing loss), disease and ear infection, head or ear trauma, tumor, ototoxic drugs (drug-induced hearing loss).
< P style = "color:; font family: Arial, Verdana, sans serif;" >
Under normal circumstances, the inner ear hair cells are responsible for transforming the sound collected by the outer ear and conducted by the middle ear into electrical pulses, which are then transmitted to the brain by the auditory nerve, and then interpreted by the brain as recognizable sound.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
< P style = "color:; font family: Arial, Verdana, sans serif;" >
< P style = "color:; font family: Arial, Verdana, sans serif;" >
Sensorineural hearing loss means that the inner ear hair cells or the neural pathways connecting the inner ear and the brain are damaged. Sensorineural hearing loss is a permanent hearing loss. At present, we can’t repair the damaged hair cells by surgery. Generally speaking, hearing aids are recommended to compensate for hearing loss.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
In addition, for the hearing loss with little or no effect of some hearing aids, the cochlear implant can be used to bypass the damaged part of the patient’s ears, directly stimulate the hair cells in the cochlea, so that people can regain the sound.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
Children and adults with severe to very severe sensorineural hearing loss may consider implantation of cochlear implants to restore part of their hearing.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
< P style = "color:; font family: Arial, Verdana, sans serif;" >
< P style = "color:; font family: Arial, Verdana, sans serif;" >
Unlike the traditional hearing aids, cochlear implants bypass the damaged part of the auditory system and directly stimulate the auditory nerve.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
Usually, when the compensation of hearing aids is not very effective, doctors will recommend the choice of cochlear implant. Before the operation, professional doctors in professional hospitals need to make a comprehensive assessment of the hearing and health status of the hearing impaired people, and only those who meet the implantation standards can be operated.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
Cochlear implant is a kind of invasive treatment, so doctors usually only give surgical suggestions to those with severe or above hearing impairment who have little or no effect of hearing aids.

Can conductive hearing loss be treated surgically?
< P style = "color:; font family: Arial, Verdana, sans serif;" >
< P style = "color:; font family: Arial, Verdana, sans serif;" >
< P style = "color:; font family: Arial, Verdana, sans serif;" >
Conductive hearing loss refers to the presence of lesions in the outer or middle ear that cause the sound to be blocked before it reaches the inner ear.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
Such hearing loss may be temporary or permanent, depending on the cause of the disease. In some cases, medical treatment or surgical intervention can restore hearing.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
Rong Erjun listed two common operations to help you understand.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
1. Catheterization of middle ear
< P style = "color:; font family: Arial, Verdana, sans serif;" >
< P style = "color:; font family: Arial, Verdana, sans serif;" >
< P style = "color:; font family: Arial, Verdana, sans serif;" >
Ear inflammation is high in children. According to the American Academy of Otolaryngology, children have at least one ear inflammation before the age of 5 Ear inflammation usually disappears without permanent damage, but some children suffer from chronic otitis media, which over time leads to hearing loss, poor academic performance, and behavioral or speech disorders.

In this case, the doctor will suggest to place a middle ear tube or pressure balance tube in the ear to relieve the increased pressure of tympanic membrane when the middle ear effusion cannot be discharged.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
The short-term tube usually falls off within 6 to 18 months, while the long-term tube needs to be removed by a professional otolaryngologist.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
2. Stapedectomy
< P style = "color:; font family: Arial, Verdana, sans serif;" >
< P style = "color:; font family: Arial, Verdana, sans serif;" >
< P style = "color:; font family: Arial, Verdana, sans serif;" >
Just as atherosclerosis can cause arteriosclerosis, otosclerosis refers to abnormal hardening of the floor of the stapes in the middle ear, resulting in hearing loss.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
At present, the treatment of otosclerosis is mainly surgery, in which stapedectomy is recognized as the treatment method
< P style = "color:; font family: Arial, Verdana, sans serif;" >
The stapes with abnormal sclerosis were partially or completely removed, and the stapes were replaced by the stapes made of the residual stapes, or other bone or cartilage columns, and various organic and inorganic materials between the long process of incus and vestibular window.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
< P style = "color:; font family: Arial, Verdana, sans serif;" >
< P style = "color:; font family: Arial, Verdana, sans serif;" >
There are three types of otosclerosis.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
Stapes sclerosis: sclerosis spreads to the stapes and blocks its vibration, leading to conductive hearing loss, which can usually be cured by stapedectomy.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
Cochlear sclerosis: sclerosis invades the cochlea and causes permanent damage to the sensory hair cells or nerve pathways connecting the inner ear and the brain, resulting in sensorineural hearing loss. In this case, stapedectomy has no effect.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
Mixed type of otosclerosis: both of the above, with the development of the disease.
< P style = "color:; font family: Arial, Verdana, sans serif;" >
So… The operation is not suitable for every hearing impaired person. The main reason is conductive hearing loss
< P style = "color:; font family: Arial, Verdana, sans serif;" >
We hope that in the near future, we can have more ways to help the weak listeners listen better. However, at present, surgery can only improve some types of hearing loss. For most of the hearing impaired people, the simplest and most effective way is to wear hearing aids.
