Am I better candidate for a chin implant or jaw surgery? (photos)

I have a chin implant scheduled. My surgeon was thinking an extended one along my jaw in a size 1 or 2. My concern comes from an earlier consultation suggesting I have a consultation for jaw surgery. This felt too risky for me. If it was a functional issue instead of cosmetic I was more willing to consider. I came back to discuss chin implant but the apt was rushed due to schedule issues. The dr is good in the area and was recommended by someone I trust. Do you think I am a candidate for implant
