SD: standard deviation; SLNB: sentinel lymph node biopsy; ALND: axillary lymph node dissection; NSM: nipple-sparing mastectomy; SSM: skin-sparing mastectomy; LDMF: latissimus dorsi muscle flap; USD: United States dollar. a There were two patients with no axillary surgery. One patient with multiple tumors was diagnosed with benign tumors with intraoperative frozen section; another patient had undergone traditional NSM, ALND, and expander breast reconstruction previously. b One patient had undergone NSM. Subcutaneous and muscular dissection is performed to enter the pocket and remove the tissue expander in this surgery.
