Buttocks size asymmetry should not occur if the same size implant was placed in each buttocks cheek; this can happen if the implant pocket was made smaller on one cheek, i.e. that the implant is in a smaller pocket and being squeezed in. A physical examination can help determined what the problem is.
Great question. It is always normal to have minor discrepancies in buttock size and shape with both implants and fat transfer. Pre-existing differences, implant placement, and fat graft survival or placement can all result individually or combined in some minor asymmetry. That said, you should still look noticeably different and amazing!It takes a great deal of experience to perfect technique and get reliable and long-lasting results that will age well whether it’s using fat only, butt implants only, or both. In the end, it’s important to choose whatever means necessary to achieve your desired goals for size, but more importantly shape!
Keep in close contact with your plastic surgeon to assure healing is going as expected, and if needed, get a second opinion. Best, Dr. Chacón.
A noticeable size difference between the buttock cheeks is often caused by one side having a higher fat survival rate than the other. A [minor] touch-up is usually enough to achieve a more balanced appearance; however, revisions are typically performed after about 4-6 months to have a better assessment of the underlying anatomies and the problems that must be addressed.
Good luck and best wishes.
