is image guided sinus surgery like having another ct scan of head/sinuses? should one worry about commulative radiological exposure?

Yes and no: Image guided sinus surgery allows your surgeon to more accurately identify where they are working in an effort to reduce the chance of surgical injury and to assure that the sinus issues you suffer from are treated as effectively as possible. This does require additional radiation exposure for the scans, something that one should keep to a minimum. For many, benefits outweigh the risk.

Risk vs Benefit: Make sure there is good medical necessity before more tests using ionizing radiation. Image guided surgery uses a low dose ct. But, the risk of the current medical problem may easily outweigh the potential future risk. Almost all data is from nuclear incidents with much higher radiation in 1 large dose. It is difficult to calculate risk at low levels used in ct over months/yr.

Not definitively: A lot of image guided surgery relies on a scan you already had with no new radiation at surgery. So if that's the case you don't need to worry about radiation. If, on the other hand, there will be an intraoperative scan then yes, there is extra radiation. I would not see many cases that intraop scanning would be necessary for sinus surgery. That is more needed for tumor surgery.
