Thin and small patients tend to have problems with implants such as palpable edges or wrinkling or unnaturally round breasts due to insufficient skin to cover implants. These problems can also be solved using autologous fat to fill and correct the concavity or wrinkles. The surgery is similar to that for primary breast augmentation with autologous fat. The surgeon takes an adequate amount of fat, purify it, and inject it in local areas with an implant edge or concavity. Injections are superficially made in cutaneous tissues above implants while avoiding damage to the implants. Using a sufficient amount of fat, problems with implants such as their texture or appearance can be improved without revision surgeries. In addition, some problems with breast shapes after implants, e.g., distanced breasts or upper breasts not full enough, can be improved using local fat injection, saving suffering from a second augmentation with implants. However, this surgery still has the drawback of autologous fat absorption. Patients need to completely stop breast massage after the procedure to prevent excessive loss of fat cells. Thus, the best timing for the surgery would be after the care period of the implant surgery, when breast massage is no longer needed.
