Surgery as such is not a dangerous one. It is routinely performed on children with tonsil
problems. In your case, the wheezing
has to be adequately controlled, without that I do not think so even anesthesiologist will agree for surgery. According to the grades you have mentioned I think it is better for you to go for surgery once the acute problems are controlled. Also, there is nothing called removal of half tonsil as such. If the tonsil and adenoids
have to be removed it has to be removed completely. Any more doubts you are welcome.
