Yes, the surgery fixed it!
This is my doctor, he's awesome:
https://www.drwalkerortho.com/airway-orthodontics/for-adults/ ... highly recommend skimming the info on his site. I didn't have sleep apnea, but I 100% had airway issues (and a small upper palette) which were causing me to grind my teeth.
It's quite sad that only some orthodontists understand the issues with airways / jaws and focus only on straightening teeth. My friend who is a dentist just quit her job as a dentist to go back to school (orthodontic residency) to learn about it because of how passionate she is about the misinformation out there.
