I dont know if its hypocritical as much as its something a lot of people do not want to openly admit. Its like saying I had jaw surgery to look better, and that makes it seem superficial or unnecessary. Like... its some kind of a cosmetic procedure, because a chunk of society has an adversity to such a concept.
And directly or indirectly, this surgery has serious aesthetic changes. It isnt like a hip replacement or gall bladder removal surgery. We all have different reasoning behind WHY we go for jaw surgery, some of us have arthritic joints, or condylar reabsorption, or severe TMJ, asymmetry, excess or lack of certain features related to jaw development.
At the end of the day I think something has to be 'off' with your jaws in order for you to be a candidate for jaw surgery. Why the hell am I rambling lol.
