Hi Jen,
I had the 3-D radiation and I had clean margins after surgery, but, I had one lymphnode that tested positive for cancer so IMRT was out. I also had the radiation to both sides of my face, from the middle of my cheeks down to my armpits. I only had boost treatments to my left side, the side that had cancer. They were able to have the radiation beam avoid my salivary gland on the "good" side so I have a fair amount of saliva. Make sure to ask if that is possible in your case.
Take care,
Minnie
