Most of us receive sound in two ways. We hear by air conduction via the ear canal and middle ear to the inner ear (cochlea). And we hear through bone conduction, where vibrations bypass the outer and middle ear, traveling directly to the inner ear through the jaw and skull bone. This explains why you can still hear sound if you block your ears.
Using bone conduction, sound is conduced naturally through the bone directly to the cochlea, independent of the outer and middle ear. A BCI system uses this natural process by amplifying sound signals, converting them into vibrations and transmitting them to an implant in the bone.
The bone then conducts the vibrations directly to the inner ear, which is embedded in bone. This is the reason why such implants are also called bone conduction implants.
In the inner ear, the mechanical vibrations are converted into nerve signals and transmitted to the brain via the auditory nerve and perceived as sound.
Implantable bone conduction is, therefore, an effective hearing solution for people with conductive or mixed hearing loss because it bypasses any problems associated with the outer or middle ear. The system can also help those who suffer from single sided sensorineural deafness by transmitting sound received on the deaf side directly to the hearing ear.
Ask yourself the following questions:
If you answered you to any of these questions, you may be a candidate for a BCI system. Talk to your hearing professional to learn more.
A small titanium implant is placed in the bone behind the ear where it osseointegrates with living bone. Put simply, it becomes 'one with the bone'. It's the same process that secures dental implants.
Osseointegration takes about three months for adults and six months for children. Once this has taken place an abutment is attached to the fixture and a sound processor is clipped on.
The Baha Attract System transmits sound vibrations to the inner ear through a magnetic connection between the sound processor and the implant under the skin. The benefit being that there is no skin penetrating abutment, providing a good aesthetic outcome with no need for daily care.
The Baha Connect System transmits vibrations through an abutment which connects the sound processor to the implant. Using the DermaLock TM technology the skin is left intact around the abutment. Here the major benefit is the efficient transmission of vibrations, providing maximum amplification.
The Bonebridge is a bone conduction implant system, consisting of an external audio processor, worn behind the ear and an implant, positioned surgically under the skin.
Sound waves are recorded by the microphones of the audio processor. The audio processor converts the sound into electrical signals. These electrical signals are transferred through the intact skin to the implanted part of the Bonebridge system.
One of the unique features of any of the BCI systems is that a prospective recipient can test it prior to implantation. Most are amazed. Not only by how much better they can hear, but the quality and clarity of sound provided. Speak to our clinician or surgeon to try a BCI.
Babies and young children have very thin bones and may not be ready for an implant. The Baha on softband is the ideal early intervention alternative. The softband allows the sound processor to be worn, without the implant. Easy to use and comfortable, providing infants and toddlers with the amplification they need to facilitate language development.
My experience with cochlear implant My name is Gerald Andrew; I am 29 year old male Tanzanian. Last year (2009) was one of the most memorable for me. It’s when I received my cochlear implant at Apollo hospital in New Delhi after Read More »
I wanted to thank you immensely for the help that you provided to my father and thus to our family by giving him the gift of hearing. He is now recovering well and is able to hear all the conversations as normally as anyone else can.
My father, underwent a Stapedotomy ear surgery to correc ct his hearing problem, first in one ear and then 6 months later in the other. The result of the surgery was better than expected and post full recovery my father is able to hear very well. Read More »
My experience with cochlear implant My name is Gerald Andrew; I am 29 year old male Tanzanian. Last year (2009) was one of the most memorable for me. It’s when I received my cochlear implant at Apollo hospital in New Delhi after more than three years of hearing loss. Everyone’s experience with coch hlear implant is a bit different therefore, am happy to share mine with anybody out there, from the moment I lost my hearing, my experience during my stay at Apollo Hospital and one year later on, after cochlear implant.
