Dear Ms. Landennrey97,Thank you for your story, photos, desired post operative appearance and questions. Unfortunately with out a exam of your tissues I can can only make general comments. I hope find the following helpful.The amount of fat that takes depends:1) the gentle technique of harvest providing the least amount of damage/trauma to the fat cells2) how the fat is injected3) the receipent area (good blood supply, lack of previous scars, etc.)4) postoperative care5) genetics of the individual The process for performing a BBL is the same regardless of the patients weight or fat location:1) harvest the fat 2) purify the fat3) sculpting the buttock:a) with precise liposculpting b) with precise fat injectionThe bottom line: 1)fat survival as a graft is multifactoral but usually varies between 70-80%.2)the fat that doesn't survive is broken down, dissolves and is excreted by our body The amount injected fat depends on how much fat there is available to harvest.Just importantly the liposuction should be done to "sculpt" other parts of the body to attain a body that is in proportion and attractive. Thus a small amount of fat can go along way or in contrast a large amount may not give you the desird appearance One can try to gain weight prior to the procedure in hope that the areas you can the weight can be liposuctioned. Caveat: all fat that is gained may not be deposited in areas that can be liposuctioned. Please bring your collected and desired model photos and schedule several appointments with experienced Plastic Surgeon who is Certified by the American Board of Plastic Surgery and ideally a member of the American Society for Aesthetic Plastic Surgery (denoting by membership as having met additional criteria and a focus on Cosmetic Plastic Surgery).
