Would a sliding genio help increase my chin height and be a good surgery for my desired morph below? (Photo)

As lighting genie of plasty is probably better than using an implant if you’re primarily looking to gain vertical height. Anterra projection will be excessive in your case and will deepen Your labor your labiomental fold excessively.
Talk to some local board certified plastic surgeons who perform the sliding genioplasty or talk to oral surgeons in your community. not all plastic surgeons performed this lighting genie of blasty and it seems more common for oral surgeons to do them at least in our community.
