I have a project that I would like to undertake for one of my friends. She's got a problem that as far as I am aware, is pretty rare.

I need more information from her, but I know that she is deaf in her right ear.

The reason she is deaf is that she doesn't have any of the hearing bones, but still has a fully functional cochlea.

Now, long story short, there is no way to get prosthetic parts because there's nothing they can be attached to. The head ENT in Winnipeg, and in Toronto have said that she will be deaf for the rest of her life because there is nothing that can be done to help her.

I would like to attempt to find a solution to the problem.

IF the sound vibrations could actually reach her cochlea, she's got perfect hearing again.

So what I need to design is some kind of device that can take in sounds and somehow reproduce the vibrations so that her cochlea can take them in and stimulate the auditory nerve.

If you guys have any suggestions on places I can go for more information, help, etc, I'm all ears (pun intended :p).

If you have any theoretical or practical input I'd love to hear it as well.

Stanford has a biomechanical engineering program. Maybe after you graduate from that, you'll have some sort of a clue as to where to start with a project like this.

It would be my guess that if you come up with a solution, you will be very very rich.

Contact some american doctors. They would be more willing to try it then a canandian doctor. But get insurance first :)

So you're saying her ear mechanism is absent of the malleus, anvil and stirrup? The oval window is ok? Is the endolymphatic fluid normal? Balance - vestibular compensation, ocular reflexes, etc? That is quite fascinating. :)

Yes, I'm sure the other 15 or so people in the world who suffer from this malady would pay dearly for this treatment. :laugh:

If the problem is rare, no company is going to bother to develop a solution. I highly doubt anything but a synthetic set of the 3 ear bones will work, and how those will be implanted, god only knows.

Unless you can come up with a little mic with a wire that you loop all through her ear, all the way to her cochlea, and bang on it like a hammer.

But this isnt a weekend project. Like they saiod, nothing to attach it to.

Well here's someone you may want to see...

http://www.luhs.org/depts/otolaryn/2a6_leonetti.html

It would require a visit to the states, but I'm sure he could consult on the phone or something. He's an amazing Doctor...just look at his resume.

Anyways, I went to him because I suspected I was sufferring from the misdiagnosis of a cholesteatoma (benign cyst in the inner ear/ear drum.

I had to have a mastoidectomy, tympanoplasty as well as a list of other things done. Basically he took out my ear bones, drilled out my mastoid bone, rebuild my hearing bones and ear drum and some other great stuff.

Try calling his office.

As far as I know, absolutely everything is fine. The problem is that there is no way for the sound waves to get to her cochlea because the ear has essentially been hollowed out.

She's had surgery 6 times so far since she was 5 I think.

She's probably had 2 or 3 prosthetic eardrums already.

No she can't hear a tuning fork. The sound never makes it to her cochlea

i'm deaf myself and i don't think canada help that much.

in america, you get insurance coverage for cochlea implant in order to hear again (with cochlea implant equipment.)

i don't want to get my head operated by doctors for cochlea implant and plus i do play sports so the more risk of something hitting my head could damage the cochlea implant.

Yes, talking to doctors first would be a good idea, that is quite an undertaking, I wish you the best of luck.

While you're at it, can you come up with a solution to nerve damage? I have half my hearing lost in my left ear. :p ;)
