types of sinus surgery

[Guest guest]

After a year of chronic sinusitis, I'm getting surgery. This dr. uses

" image guided surgery " and I had to get a special CT Scan with VTI

(whatever that is) with a plastic thing on my head. Would someone know

the different ways that surgeries can be done and has anyone been

operated on this way? I also know of the new balloon surgery. A couple

of other dr's I saw use a tv screen of some sort. Of course I don't

want to be bothered with this, but it seems like I have a choice of

surgery or a permanently clogged up head.

Thanks.
