With the recent spurt in treating deafness in India, particularly after the launch of the National Deafness Program, there has been a noticeable rise in the awareness of and implementation of cochlear and hearing implants in India. A CI or cochlear implant mechanism helps restore hearing in individuals with severe-to-profound sensorineural hearing impediment. This is the latest treatment for individuals where hearing aids either provide little benefit or don’t work at all.
CI is a medical that actually replaces a sense. It bypasses the inner ear’s non-functioning parts and provides direct electrical stimulation to the cochlea’s nerve fibres. It comprises an audio processor worn externally behind the ear as also an internal implant, that is placed surgically inside the ear.
Among the popular cochlear and hearing implants in India is also EAS that is effective in helping patients hear high-frequency sounds. Those who can’t hear high-frequency sounds are said to be suffering from Partial Deafness and EAS combines 2 technologies: CI for high frequencies with acoustic amplification to catch low frequency sounds. In their totality, they encompass the full hearing range in both adults and children.
Vibrant Soundbridge is yet implant system of the middle ear and is ranked as one of the most effective cochlear and hearing implants in India for patients who can’t use traditional hearing aids for certain medical reasons. This happens usually when permanent hearing loss happens after surgery is done on the middle ear or hearing aids can’t be used because of chronic inflammation of the ear canal. This implant works well in cases of mild to acute sensorineural hearing loss and also for mixed or conductive hearing loss. This implant converts environmental signals into mechanical vibrations which stimulate the middle ear structures, allowing the patient to perceive high-pitched tones exceptionally well.
Hearing systems that are bone anchored are designed in a manner that uses the body’s natural tendency to transmit sound by way of bone conduction. Its sound processor converts external sounds into vibrations to be transmitted through the skull bone, directly into the inner ear. This hearing implant comprises 3 parts: A tiny, 3-4 mm titanium implant that is placed on the bone behind the affected ear; an abutment seamlessly placed under the skin that enables attaching the sound processor and another sound processor placed discreetly behind the affected ear.
The sound processor connects with the abutment by just a click and catches sound waves like traditional hearing aids do. However, the sound waves instead of passing through the ear canal actually become sound vibrations that pass through the skull bone. Because of the bone and sound processor’s direct connection because of the implant and the abutment, the patient’s skin doesn’t dampen the vibrations, giving out a much clearer sound. The additional advantage is that the sound processor can be clicked off while sleeping or showering.
Another implant is the Ponto System that works on Direct Sound Transmission, providing best amplification as also output. Ponto Surgery enables placing the implant as also the abutment in a minimally invasive manner thus, requiring minimum time and suturing that substantially reduces scarring and also heals faster. Moreover, if it doesn’t suit you, it can always be taken out.
