Breast augmentation with artificial implants is one of the most frequently performed aesthetic surgeries but is associated with various complications, such as capsular contracture, that lead to implant removal or replacement at a relatively high rate. Thus, we used transplantation of autologous fat tissue (cell-assisted lipotransfer; CAL) by prof. Kotaro Yoshimura and Cellport Clinic Japan, that is a suitable methodology for the replacement of breast implants.
