Jaw surgery

I have a consultation tomorrow i prepared about 6 pag of questions. ( i have a bad memory) My question is i have no functional issues that im aware of ,my main concern is aesthetic. If thats the thing should i really consider this type of invasive surgery can i just camouflage it with fillers or prosthetic? Ive seen cases that they camouflage it with fillers. I dont want 100% symetry but i wanna look close to normal. I saw a few comments saying if its not functional dont go thru it.
