The preoperative drawing lines were fully incised; the cranial resection margin was first developed by vertical dissection down to the pectoralis fascia. Thereafter, the dissection is carried out between the nipple-areola complex and the segment, and under palpable control, the segment including the skin is excised (Fig. 6.2).

Without further dissection between the skin and the breast, the defect is simply closed (Fig. 6.3).
