I’m male in my mid twenties who is in average shape, my face appears to have definition from a frontal view, but I have very little jaw definition from profile view, my cheeks slope directly into my neck. Are jaw implants my best choice, or would a chin modification help this more?
It really depends. It is hard to know from your description. There are many options from chin implants, to moving your chin (genioplasty), to breaking your jaw and repositioning it. It may be as simple as liposuction of your neck to help tighten the neck. It is best to use this site to find a few Board Certified Plastic Surgeons in your area and seek out a personal consultation.
Thank you for sharing your question. Unfortunately without an in-person examination of your tissues, nor a discussion of your goal results, it is difficult to offer a treatment recommendation. I would recommend seeing a couple of ASPS board certified plastic surgeons in consultation to discuss.
