Residual Hearing

September 26, 2005

Hi, All,

Just a note on the subject of maintaining residual hearing following

implantation. Nope - not me - not with the N24C and not with the Freedom.

There

wasn't much to lose in the first but I did have some worth noting in the most

recent ear implanted. I made the decision to go ahead, despite knowing I

could/would lose it in the interest of gaining much more. I'll let you know at

the end of the week if this works out, as I get hooked up on Wed/Thursday.

Hi Jackie,

We'll all be waiting for that report too! Good Luck and please don't

make us wait long.

Regarding the subject of residual hearing - I do have some which I

find simply amazing.

What do they mean that CIs are designed to preserve what residual hearing you

have? If they promote that statement and all residual hearing is lost, then they

say: it might happen that residual hearing is lost. I have been totally Deaf

before my CIs so they didn't need to 'try' preserve. Another question I have is,

if a person have residual hearing with which you can hear mumbled sounds without

a HA (the HA doesn't help to make speech clearer it only amplify the mumbled

sounds, in the aboue situation) will you still have that ability to hear the

mumbled sounds without placing your ear next to the sound source without the CI?

Ilana, If a person has residual hearing before getting a CI in that ear,

then if any of it is preserved, it will almost certainly be less than

previously.

In my opinion, saying they may be able to save some of your hearing is done

as a selling point. A lot of people shy away from getting a CI because they

don't want to lose the hearing in that ear.

Hi Ilana, Manufacturers work at trying to design electrodes that can be

inserted without doing any damage to the remaining functioning hair cells

and structure of the cochlea. Cochlear Corporation came up with the soft

tip contour design with this in mind along with the concept of getting the

electrode placed as closely as possible to the inner most wall of the

cochlea which places it the closest possible to the hearing nerve giving it

better power and stimulation results.

Ralph, if you search the internet, you will find there are studies that have

proven that the design of the electrode indeed determines the degree of

cochlea damage. Maintaining residual hearing for the purpose of

functionality might not be a reasonable expectation, as obviously if the

residual hearing were functional, why would one want to get a CI in the

first place. However, I would think that the more intact the cochlea is and

the more surviving hair cells there might be the better results a person

might get from the CI stimulation. I wouldn't brush it off as a " marketing "

ploy as all of the companies are working hard and spending huge amounts of

research dollars to find the ultimate electrode solution.

Just my thoughts,
