2C it is a very big deal, if someday, they were to devise a way for all of us to be able to hear normally or even better than with a CI, we dont want our chances ruined because we destroyed our natural hearing *residual* do we?
Also with the CI there is no guarantee it will work for you. With preserving residual hearing, there is a chance we could either wait for better hearing aids or a better implant or better something to come out.
Even though my residual hearing worsened to such a degree that the current hearing aids on the market arent helping, isnt it possible that someday they may develop one that will with my degree of loss? If the CI hadnt worked and they dont work towards preserving residual hearing, it may not matter what they develop in the future.
