Yikes,
Surgery on vocal cords?
Do they actually do that?
Perhaps you mean surgery that will have impact on the vocal cords? (Any intubation will prevent the vocal cords from functioning properly.)
Whatver, good luck, and I sincerely hope that the procedure goes well.
Surgery is fairly common in people who sing. I know one who had surgery and he is still having to take it easy for a while every year. When I had it about 5 years ago, I did not have any trouble eating. I had a polyp.
