Hasn't your surgeon discussed post-operative care with you?  My ENT gave
me written instructions as to what I should do, which included the need
to make some follow-up appointments with him.  These instructions
included an oral antibiotic I was to take starting the day after the
surgery.  My ENT also gave me a prescription for a painkiller I could
take, in case the post-operative discomfort was too great.

These instructions said that I might have some bloody post-operative
drainage for a week or so, but not how I was to deal with that.  I
learned the hard way to wear old clothes I didn't care about staining.
Your surgeon's nurse should show you how to affix a so-called "moustache
bandage" between your upper lip and your nose, to absorb some of the
bloody secretions for the first few days.  You might want to stock up on
surgical adhesive tape and gauze, because that's how "moustache
bandages" are made.

Good luck!  Hope it all goes well for you!

It's nothing to worry about really.
If you have not had one recently, get a general health checkup from your Family
Doctor or Internist including EKG and clotting time and bring it with you and
give it to them on admission.  Also bring along the CT scans if they do  not
have them already.
Do not eat or drink after midnight on the day before.
Be as well rested as possible.

Rhinoplasty is cosmetic surgery, no--a "nose job"? I don't see how that
would help your sinus infections. No sinus surgery involved?

As far as septoplasty, I would recommend against it except for people whose
septum is extremely deformed, which is thought to be the main cause of one's
nasal-sinus problems.

I make that recommendation based on my experience--when I had one of my
sinus and turbinate surgeries done, the ENT also did septoplasty from my
mildly deviated septum. In that surgery my septum developed a hole in it, a
perforation.

In another sinus surgery (with a different surgeon) the following year, the
doc tried to patch the perforation, but that didn't work, and now the hole
is larger than ever. (In one sense better large than small. When I first had
the perforation, it was smaller, and made a very annoying whistling sound
with my breathing.) I've been told the perforation contributes to my severe
rhinitis, crusting, etc.

I believe that is always a risk with a septoplasty. Therefore, unless your
septum is extremely deviated, and the docs (get more than one opinion) are
certain that straightening the septum would make a large difference in your
symptoms, I'd recommend against it. (Not just--"while we are working on your
sinuses and/or turbinates we might as well straighten your septum as well".
I wouldn't suggest going along with that.)
