Six months after breast augmentation, you're looking at the result for a 22-year-old patient who received Sientra silicone gel implants placed submuscularly. The submuscular position puts the implant beneath the pectoralis muscle, which adds tissue coverage over the upper pole and is a common choice for patients with less existing breast tissue. The before photo shows surgical planning markings drawn on the skin, a standard step for mapping incision placement and pocket boundaries before the procedure begins. At the six-month mark, the implants have settled fully into position. Sientra's silicone gel devices are FDA-approved and manufactured to a single-stage shell process. Individual results vary from patient to patient.
