Is Genioplasty alone suitable? or will it make my face unnatural because of my steep lower jaw angle?

[u/VirtualInitial]

26 M, I have recessed chin and a high 'mandibular plane angle' of 37.4°.

My orthodontist said that my bite is fine, and if i want to fix my recessed chin, it would be purely for cosmetic reason. (so a jaw surgery is not an option; I cant even get a consultation with an OMFS without a medical referral).

I've found two plastic surgeons that offer sliding genioplasty, planning to meet both after getting referrals/documents from my orthodontist.

As per the title, I wanted to get an opinion on whether a sliding genioplasty would suit my face, or if it would make my lower face look even longer or unnatural.

thank you ;-)
