How much projection can fat grafting to the chin get?

Thank you for your question.  Fat transfer to the chin can be helpful, but not as precise and defined as an implant.  The soft diffuse nature of fat transfer limits the amount of augmenation and the precision you can achieve in such a small tight space.  Two transfers area usually enought to achieve a result.  If you are dissatisfied with two transfers, it is unlikely that a third will make you happy.  Try to be more precise with your surgeon regarding what you are trying to achieve.  Next, ask whether an implant or fat is the best way to get there.  Best wishes.

I think a combination approach would be best to achieve the results you want. I find the best option is using fillers like restylane silk or belotero.  Secondarily sculptra, PRP do well to improve symmetry and volumize the face. Please see an expert.  Best, Dr. Emer.

It may be possible to achieve a permanent correction but as to how many procedures it will take is hard to say.  You may be better off with a chin implant since this procedure is quite straightforward.  Best wishes, Dr. T.
