Can a fat transfer be done to the head/skull for flat head?

Dear BrittE92,fat can be transferred to your skull to give more projection but it would be hard to predict the final results. Another option are dermal fillers. I would suggest you to consult a board-certified plastic surgeon.Daniel Barrett, MD, MHA, MS

Noi method of injection, regardless of the material used, is going to work for skull augmentation in any reliable manner. The scalp tissues are very tight and will not be pushed out like many other areas of the body. Fat and fillers are soft materials that do not provide enough push to expand out the tight overlying scalp. While fat can be injected underneath the scalp in some amounts it does not survive well and the scalp 'wins' because it pushes it right back down over time with the fat absorption. Your assumption is correct in that fat does poorly in places where there is not much natural fat but it does really poorly in tissues that are very tight and do not have much fat..

As long as the tissue that fat is being injected in has a good blood supply, fat can be injected and have the potential for some survival. Realize that fat is soft and malleable so it will not have the same firmness/feel as bone. Probably small amounts can be injected to help contour areas but a "large" amount in one area will not withstand the effects of pressure or feel natural. Fillers like PMMA are not really a cost effective solution given what you are trying to accomplish.Steven Turkeltaub, MD
