We performed immediate breast reconstruction after nipple-sparing mastectomy or skin-sparing mastectomy and evaluated the reconstruction procedure, cosmesis, and complications. Among the 30 patients included in the study, 6 received latissimus dorsi flaps, 1 received a transverse rectus abdominis myocutaneous flap, 7 received deep inferior epigastric perforator flaps, 1 received an implant, and 15 received tissue expanders. In addition, the results were excellent in 25 patients, good in 3 patients, and poor in 2 patients. As the number of patients with breast cancer is increasing, the demand for breast reconstruction will increase. Therefore, it is essential to choose an appropriate method of breast reconstruction for each case.
