Will a septoplasy leave a noticeable scar, or leave a scar at all if my septum deviation is higher within the nose?

I'm an actress and constantly on camera. My nose breathing has gotten worse over the years and i cant breathe when working out. Ever since I've turned 18, I've tried to sleep with a closed mouth and tried many sleeping tools. terrible mistake. i ended up awaking and gasping for air. i wake up with a dry mouth and my teeth are beginning to yellow and decay. I've had it! its messing up my daily life, but i will not crush my dreams for it either. let me know if there are other things to aid it.
