It is a harsh fact that living with a hearing loss is not easy. As we know that a fully functional ear, nose and eyes make for a complete outlook of a person and even a small impairment or abnormality of the same can have grave health conditions.
Earlier it was believed that hearing problems was a result of birth defect but it has gone to become more and more common due to years of exposure to loud music, high-volume headphones, daily noise pollution, and boisterous sporting events. Hearing disorders have serious implications in a person's life and they can even see a dip in their quality of life. One can say that one in three adults over the age of 60 experience hearing loss.
What really causes hearing loss?
Hearing loss can be conductive; mostly it is caused by any occurrence of problems in the ear canal, ear drum, or middle ear and its little bones. They can also be triggered by the congenital absence of the ear canal or failure of the ear canal to be open at birth, malformation, or dysfunction of the middle ear structures. Many more causes that lead to hearing loss are infection, tumors, foreign body and trauma (skull fracture). In order to correct such severe hearing disorders, the ENT surgery hospitals In India conduct Cochlear Implantation or other surgeries as per the requirement.
Another reason for hearing loss is the Sensorineural hearing loss (SNHL), nerve-related hearing loss caused by exposure to loud noise, Head trauma, Virus or disease, Autoimmune inner ear diseases. There can also be hereditary causes, aging, inner ear malformation, Meniere’s Disease, Otosclerosis or Tumours which may add to the hearing impairments. These cases may be apt for surgery or medical treatment though the severity of the condition is also taken into account.
Mixed hearing loss is a mix of both the types of hearing loss that has been discussed above. This can be corrected with the help of a hearing aid albeit only to an extent along with medical treatment.
So what is Cochlear Implantation?
Cochlear implantation is a surgical process which implants medical devices that bypass damaged structures in the inner ear and directly stimulate the auditory nerve. These implants bring about improvement in people who have been suffering from profound hearing losses. A range of sounds is recognized by this but, normal hearing cannot be replaced
A cochlear implant is composed of an internal and external component. In this implant, the internal component is inserted through surgical means beneath the skin behind the ear, and a narrow wire is threaded into the inner ear. For the external component, an external magnetic disk is used to link the internal component. The external component resembles a behind-the-ear hearing aid to the internal one through the skin. Cochlear implants work on the principle which allows them to convert sound waves to electrical impulses so they can be transmitted to the inner ear thereby giving people the ability to hear sounds clearly and not rely much upon reading lips to understand speech. As an estimate, there are more than 188,000 people worldwide have received cochlear implantation.
Not all hearing impairment conditions qualify for Cochlear implantation! As a first step, you need to get an evaluation by a ENT surgery hospitals in Delhi and audiologist associated with a cochlear implantation clinic to be considered for the cochlear implant surgery.
