I have jaw asymmetry and was thinking about getting orthognathic surgery. Im wondering what are the long term side effects of orthognathic surgery? I have a slight underbite and if i get surgery, i would like to have my jaw surgery pushed back SLIGHTLY. Im wondering if there is effect of trouble breathing or sleep apnea/snoring after getting this surgery?
