They stuff tampons and "packing" up your nose until everything heals and the septum is straight.
It was really quite an ordeal. Keeping your nose crammed with stuff for a couple of weeks, while you cannot breathe is very frustrating.
However, once everything had been pulled out, I was a lot better. Before the surgery, I had become a nasal spray junkie; needing nasal spray often just to keep breathing. I have used no nasal spray (aside form saline) for several years. When I breathe out my nose, I can feel wind whooshing out from it. If the new method works, w/o all the hassle I went through, it sounds pretty good.
I actually had endoscopic nasal surgery, (@ $10,000) and during that they got rid of my deviated septum.....but they also found 3 polyps that were blocking spaces.....but, in the end my sinus problems were NOT cured....it took changing my diet to fix them.
