Techniques enhancement for tissue expander/implant two-stage breast reconstruction

To investigate the outcomes of breast reconstruction with employing improved techniques throughout the tissue expander/implant two-stage breast reconstructed process, which involved the tissue expander placement, the saline filling intraoperatively and postoperatively, the implant selection, and the permanent implant replacement. In this study, 68 patients who had been provided immediate or delayed tissue expander/implant two-stage breast reconstruction with autologous fat injection post-mastectomy in Peking University Third Hospital from April 2014 to September 2018 were involved, and the relevant information was analyzed retrospectively. The enhancements of the techniques, involving the incision selection, the expander placement, the principle of expansion, the management of capsule, the prosthesis selection, and the assisted reconstruction method were summarized, and the reconstruction outcomes were evaluated objectively through three-dimensional surface imaging. Among the 68 patients in this study, immedi
