ObjectiveTo explore the techniques and short-term effectivness of contralateral breast symmetrization mammaplasty in breast reconstruction. MethodsBetween February 2014 and December 2015, 11 patients received immediate or delayed breast reconstruction after nipple-sparing mastectomy (6 and 5 cases respectively) for contralateral breast symmetrization mammaplasty. The age ranged 36-55 years (mean, 45 years). The disease duration was from 7 days to 6 months (mean, 2.5 months) in 6 patients undergoing immediate breast reconstruction. According to tumor TNM staging, 2 cases were rated as TisN0M0, 3 cases as T1N0M0, and 1 case as T2N0M0. The duration was from 2 to 25 years (mean, 8 years) in 5 patients undergoing delayed breast reconstruction. The implant (7 cases) and latissimus dorsi (4 cases) were used for breast reconstruction; and breast augmentation (6 cases) and breast reduction (5 cases) were performed for contralateral breast symmetrization. ResultsOne patient had local poor wound healing postoperatively and was cured; primary healing was obtained in the other patients, and no other postoperative complication of infection, implant exposure or capsular contracture was found. The patients were followed up 3 to 24 months (mean, 12 months). The reconstructive outcomes were excellent in 9 cases and good in 2 cases, with an excellent and good rate of 100%. There was no recurrence or metastasis. ConclusionSimultaneous contralateral symmetrization with augmentation/reduction mammaplasty after breast reconstruction can obtain satisfactory symmetric outcomes.
