Sliding genioplasty? Jaw surgery? (Photo)

Hello, so for a while now i've felt that either my chin is weak or the entire lower jaw. I've read a lot a about the procedure called "sliding genioplasty" but i'm unsure if i'm a candidate for it. For some background info i used to have a "deep bite" that i had corrected with orthodontics, but i am still left unsatisfied clearly, which is why i'm considering this. I also have some small speech issues but that could be unrelated.
