Direct-to-implant breast reconstruction is a standard method of implant-based reconstruction; however, the risk of skin necrosis and implant failure exists. During simultaneous contralateral augmentation, an implant larger than the resected tissue must be inserted to balance both sides, which may increase the risk of complications. This study examined the differences in the incidence of complications between the single-stage direct-to-implant reconstruction and 2-stage reconstruction when contralateral augmentation was performed simultaneously.


This study included 99 patients who underwent implant-based breast reconstruction with contralateral augmentation between 2012 and 2020. A retrospective chart review was conducted and the patients were divided into 2 groups: the single-stage reconstruction (n = 61) and 2-stage reconstruction (TSR, n = 38) groups. Demographic data and surgical and oncological information were collected. Complications including skin necrosis and reconstruction failure were investigated as the primary outcome.


Implant volume and contralateral implant volume were significantly greater in TSR group than in the single-stage reconstruction group. There were no significant differences in the incidence of complications and reconstruction failure rates between both groups. The nipple-sparing mastectomy was the risk factor for complications. Furthermore, the risk factors for mastectomy skin necrosis were implant volume and differences in the volume of both implants.


Single-stage reconstruction did not increase the risk of complications compared with TSR when implants that were larger than the resected tissue were inserted after mastectomy. Proper patient selection and selection of implants that are not excessively large could satisfy patients' cosmetic needs in a single operation.
