I'd like to get some filler in my tear troughs, cheeks and lips. Is it better to wait until after a Septoplasty?

Is it better to wait until after the surgery? Or does it not matter? I'm getting a cat scan on my nose today. Does filler show up on a cat scan? I just don't want things to be different for when the dr sees the cat scan and if things would be different if I had filler after that. I don't want him going in and getting any surprises. Am I worrying for nothing? Also, if I get Botox before the surgery is there a timeline I should be considering?
