I am under the impression that you are doing it on purpose by giving banjo a hard time when you knew the fact that surgery can happen anything is possible. Sadly, several kids who had surgery for CI and unfortunately that doctors performed mistakely and kids' residual hearing is gone and some forms of inside ears are gone therefore CI didnt work at all. what a waste when the kids HAd some residual hearing. SAD. Like i said doctors are not god or perfect.
You would be under that impression, or at least do your very best to insinuate it.. You are wrong..
But I don't give wrong information to other people. And if I see information that is wrong, I - and you - should challenge it..
Spreading misinformation is the lowest one can do..
To get back to the topic..
The main question was "Does CI affect some nerves?" and that is a BIG yes... That's the whole purpose of CI. To stimulate a nerve. And it does it well..
Sometimes, other nerves are stimulated as well. With the correct mapping this can be prevented.
Sometimes during surgery other facial nerves are touched, even though they are well monitored. This can cause strange tastes or lack of tast. Or visual things...
BUT... there are no nerves that go to any other pars of the body in the middle ear. Nerves go out from the spine. Nerves to the arms do not go via the inner ear..
Anestesia is a risk.. But that's with any surgery..
If something would happen due to this, it has nothing to do with CI surgery.. The same could happen with some other surgery or investigation that would involve aesthetics...
