Actually, Mookie, I'm not sure what your question is - but hopefully this will help. I contracted meningitis in 2004 - I was 24 years old. The believed reason that I became sick was because of a positioner used with my 2002 cochlear implant. (The positioner is a spacer that will hold the electrodes in place.)
Since my case and some others, they have ceased use of a positioner. Now, those receiving a CI will most likely be at less risk of getting meningitis from the CI itself. Just a stroke of bad luck.
I'll take a stab at your question since I'm not sure if it's even the right one, but...if a baby who has a CI were to contract meningitis, it would be possible for this baby, if he or she recovers from the illness, to hear again with the aid of the CI. I THINK this is what you're asking - correct me if I am mistaken.
If the CI is removed for whatever reason, though, the residual hearing in the once-implanted ear is forever lost.
