Editing Breast augmentation (section)

===Technical limitations===
When the patient's body has insufficient adipocyte tissue to harvest as injectable breast filler, a combination of fat grafting and breast implants might provide the desired outcome. Although non-surgical breast augmentation with fat graft injections is not associated with implant-related medical complications (filler leakage, deflation, visibility, palpability, [[capsular contracture]]), the achievable breast volumes are physically limited; the large-volume, global bust augmentations realised with breast implants are not possible with the method of structural fat grafting. Global breast augmentation contrasts with the controlled breast augmentation of fat-graft injection, in the degree of control that the plastic surgeon has in achieving the desired breast contour and volume. The controlled augmentation is realised by infiltrating and diffusing the fat grafts throughout the breast; and it is feather-layered into the adjacent pectoral areas until achieving the desired outcome of breast volume and contour. Nonetheless, the physical fullness-of-breast achieved with injected fat-grafts does not visually translate into the type of buxom fullness achieved with breast implants; hence, patients who had plentiful fat-tissue to harvest attained a maximum breast augmentation of one bra cup size in one session of fat grafting to the breast.<ref name=Coleman/>
