The number of procedures needed depends entirely on how much volume you want in the recipient site. For someone who only wants to be a little bit larger, one round of fat grafting may be sufficient. For another patient who wants complete breast reconstruction after mastectomy, multiple rounds of fat grafting will usually be necessary. Each round of fat grafting is separated by at least 3 months so that the patient’s body can fully heal in between. Some fat will always resorb after fat grafting, and it takes several months to evaluate how much fat has been retained. Thus, while a tentative timeline can be created at the beginning of the journey, the number of sessions will ultimately depend on how much fat your body retains after each round of fat grafting.
