Of various Chin augmentation options grafting fat is not a particularly good one. Tissue grafting requires an abundance of host tissue and the chin does not have this. For that reason the amount of fat that survives especially in a very precise confined space will be insufficient. If done with enough grafted fat or to a point where fat actually survives it creates an undefined bulky appearance. Do you also need to assess if forward augmentation is appropriate because this by definition well deep end or worse in it and leave your mental angle. You also need to assess if forward augmentation is appropriate because this by definition well deepen or worsen The labiomental angle. It’s hard to get a good assessment with the facial hair present but it looks like vertical height augmentation may be the better option. I recommend you stay with Standard procedures that have stood the test of time and the ones most providers use and recommend. Most likely this is going to be a sliding genioplasty for working with implants. Fillers also do a pretty nice job and do not have their limitations that fat transfer does. This area is more complex than people believe because dental occlusion, the relationship between the maxilla and the mandible have to be taken into consideration and what works for one person may not at all work for another person. Anterior augmentation will always deep in the labiomental angle or fold. To get an accurate assessment in a better understanding of treatment options I suggest having multiple in person consultations was local oral surgeons and board-certified plastic surgeons. Each Specialty add their own expertise to this field and providers from both specialties work on this condition. Oral surgeons tend to see things from a more fundamental approach looking at bone structure as being the primary cause white plastic surgeons sometimes do this but sometimes opt for simpler alternatives like placing silicone implants. There are different ways of treating this but fat transfer is probably not the way to go. Best, Mats Hagstrom MD
