Buttock implant size is essentially determined by measuring the buttock width in relation to the buttock implant width. While buttock implant sizes are limited, choosing the right size can be determined by assessing other factors such as body frame and skin tone. If the implant is larger than the buttock, complications such as implant palpability or visibility of the edges may arise. In addition, the skin tone also determines how large the implant can be, assuming the width of the implant and the width of the buttock are acceptable. If the skin tone is extremely tight, putting a big implant regardless of a large buttock can result in loss of skin secondary to pressure necrosis, as well as wound dehiscence due to an increased tension at the incision site. Most patients are given 400 to 500cc buttock implants, combined with a fat injection between 300 to 400cc. This totals the total buttock volume to about 800 to 900cc. In determining the right implant size for buttocks, these anatomical factors, along with proper medical experience, must be taken into consideration.
