For those who had CI surgery .. do you still have residual hearing? What kind is your CI? AB, Freedom and Med (sp) lol.


i know my sons father doesnt have residual hearing as its gone now as he got CI now.


So what about you?
 
If I'm not mistaken, I thought once you get CI you lose all your residual hearing in that ear? :dunno:
 
Alex, I thought so too but pacman said hes planning on getting HA for where his ci was at? he said he STILL have residual hearing, i guess? that is why I am curious??

so wondering about others... hmm
 
Smiley, I posted a comment to this question in the other thread. The audi nerve is not "cut" or even touched during CI surgery. It is necessary to hear with a CI the same as a HA or normal hearing person. This info is wrong.
The issue of retaining residual hearing is caused by the hole being drilled in the cochlea. Apparently the fluid draind from the cochlea causing the resid. hearing to disappear. There have been posts here recently saying that researchers are finding that some people with the Freedom CI are retaining their residual hearing after CI surgery. I guess it may have something to do with the size of the hole drilled into the cochlea?

yeah its very interesting.. i did posted to that too in other thread, lol. in case people is curious?

when I had the ct-scan they told me that they found hole on top of my cochleas (both left and right ear) and that is the reason why I am deaf as it was not developed right. Yet I still have residual hearing in my right ear.. and i do wear hearing aid.. i used to have residual hearing in my left ear but it was not useable due to the fact it was static so i didnt wear hearing aid. Now its gone due to Meniere's Disease.

the audiologist told me they cut thru nerves to get electrodes thru the nerves to cochlea thats what she told me. I am going to ask her again about this so i can understand this .
 
Your residual hearing is permanently destroyed once you get the CI surgery. The reason is that when the CI is activated or turned on, the electrodes in your cochlea stimulates your dead hair cells. In this case, although you might have several "live" hair cells prior to surgery, all your hair cells are completely damaged once you are implanted, in order for the stimulation to occur successfully.

This is why some people are reluctant to forego with the implantation. They have this fear that all their residual hearing will be destroyed. If they do get implanted, what if the CI isn't beneficial to them, and all their residual hearing is lost? It is a big risk most people are willing to take, but the majority of the outcomes have been positive.

I'm a Nucleus 22 CI user.
 
With the older CIs, that was true. It's now possible, though, to keep at least some residual hearing - Nucleus is doing a study. I want to say, although I'm not sure, that you do sacrifice some of the CI's effectiveness if you try to keep residual hearing, so there are cases where they don't bother.
 
Hi smiley I was implanted last May and still hear sounds in the ear that was implanted. Now I'm not saying I hear much but the sound is there. I can even make out words if they're spoken directly into the ear. But the CI is so much better then the HA's I used with my mod/severe loss that even if there was no hearing there I wouldn't care.

I have the freedom and one of the things mentioned in it's brochure is that the curved electrode array helps preserve residule hearing. I asked the audie at the CI center about that and she said that while the drs. would do their best not to damage the choclea thus prserviing hearing even with an array designed to lessen impact there is no guarentee that you'll ever hear in the implanted ear again if the electrode needed to be removed. I'd guess that the other two have come up with something or are designing something that helps preserve some hearing in the ear to.

Having said that, someone who was implanted 5 or 6 yrs ago probably would not have any residule hearing in the implanted ear , I'm not sure when they went with a curved array but befor that my understanding was it was straight and had to curve as it was inserted and that caused damage to the nerve hairs that did work thus damaging the remaining hearing? Maybe someone else can say that better.

I think you may have misunderstood. During surgery they have to work the electrode array between the facial nerve and hmmm, is there another one guys? But they tend to scrape the facial nerve and you can have a sensation like you would after getting a tooth fixed, like your mouth or tounge is still numb from the novacaine. in most people that fades, in me it only lasted a couple weeks. With their microscopes they use today severe damage is probably not a very high risk, but that would be severing of the nerve causing paralysis (sp?) in the face which I don't know if they can repair but it is probably very very rare now.

you are talking about the study using partial insertion for people who have high frequency losses? That will be interesting to see if it works.

But there is also a trail going on right now for the Envoy, which is a internal hearing aid. My daughter is participating, so far she hates it.
But the advantage the envoy would have over the external HA's is it is actually much more powerful then a HA will be interesting to see if people like it once they do heal completely and can program it to their hearing loss.

They use facial nerve monitors nowadays which practically makes it very rare that actual paralysis ever occurs. If it does, it is usually temporary. This was my main concern more than anything else when I got my CI. As for repair, er...probably slim to none as that is a major (and only) nerve for the face and the end result is permanent paralysis (on the side they put the CI). Over the decades, they really worked very hard to minimize this situation for obvious reasons.
