The procedure is performed on an outpatient basis. The area to be treated is first anesthetized with a special fluid that also helps control bleeding and facilitates fat extraction. Your surgeon then suctions fat from your neck, arms, chest, back, thighs, hips or abdomen (liposuction) through a small cannula (blunt tube). The fat obtained is then processed and purified to derive ideal fat cells for the procedure. These fat cells are drawn into syringes and injected through cannulas at precise locations and at various depths in the upper buttocks, giving them a perky appearance. Liposuction may be performed on surrounding areas to make the buttocks appear more prominent.
