Autologous fat particle injection transplantation in breast augmentation surgery is to extract fat from places where body fat accumulates (such as abdomen and thighs) with a liposuction device, filter and separate the extracted fat into pure fat, and then inject fat particles into the retromammary space and/or gland surface with a syringe. The price of autologous fat granule injection transplantation for breast augmentation surgery is about 20-40 thousand yuan. Postoperative patients need to rest for 1-4 days and rest for 7- 14 days more.
