Linda Rose,
I would have to say without a doubt in my mind that, yes, you will sing again.
I have never heard you sing and that does not matter in the least. Every patient who goes through what you are about to will experience many changes in their voice, some positive some negative. If you want to overcome the reconstruction you will. Will a recording sound the same..probably not..does that matter...no.
Singing, in fact, may strengthen and help healing if it is approached in the same manner that an athelete who sprains or breaks an ankle approaches rehabilitation. So talk to your docs and when you feel ready sing!!
If for nothing else it will certainly make you feel better.
Cheers,
Mike
