The implant with orthodox technique is usually placed into the submuscular or subglandular plane. The subglandular plane usually has implant edge visibility, especially in thin women, and causes a high incidence of fibrous capsular contracture, while the submuscular plane can cause implant distortion, breasts that are too peaked, and a relatively long recovery period. The subfascial plane for breast augmentation has many advantages over the conventional plane, such as rapid recovery, satisfactory breast shape, and lower fibrous capsular contracture. Dissections of 30 breasts on cadavers showed that a pocket can be made between the pectoralis major muscle and its pectoral fascia; the pectoralis major muscle remained intact, and integrity of the pectoral fascia was preserved. The potential pocket between the pectoralis major muscle and the pectoral fascia can be used as a plane for breast augmentation.
