What would be the best way going about a chin reduction surgically for my over projected jaw? (Photos)

(Under the chin, through the mouth?) I know there's different techniques. I'd just really like to get an idea of what my jaw itself would require. Im 22 yrs old. But it's something I've been very self conscious my whole life. Definitely would raise my self esteem a lot to have this surgery done and honestly change my life. My dentist said that I would have t breaking my jaw and moving it back to correct it. Yikes. I hope not. I don't have the best pictures but I hope they help!
