Generally, if there are changes in the intrathoracic prosthesis, it is necessary to consider whether it is displaced, ruptured, etc. Once the diagnosis is made, it must be removed as soon as possible. Autologous fat breast augmentation surgery can be performed immediately after the prosthesis is removed, and the two can be removed and performed at the same time. This can not only avoid sagging and shriveled breasts after the prosthesis is removed, but also make use of the vascularized environment created by the prosthesis, which is more conducive to the survival of autologous fat.
