How closely can chin filler emulate a genioplasty?

Very likely that combination of liposuction of neck and jawline with chin implant would be a good procedure in your case. You should discuss this option with your surgeon. If available, 3D simulation would help. Good luck.

Good Morning Enthusiastic150926,I hope this message finds you well. A genioplasty surgery usually shows non relapsing results in the long term as the titanium plates are non resorbable, as well as the fact that the bones are now fractured into a new position and hence grow in that fashion moving...

It is very difficult to decide whether chin augmentation by means of implant or genioplasty, would make a change you want. Only on the basis of in person evaluation, discussion about your goals and 3D simulation, appropriate plan of treatment can be created. Good luck.
