eduction mammoplasty (also breast reduction and reduction mammaplasty) is the plastic surgery procedure for reducing the size of large breasts. In a breast reduction surgery for re-establishing a functional bust that is proportionate to the woman's body, the critical corrective consideration is the tissue viability of the nipple-areola complex (NAC), to ensure the functional sensitivity and lactational capability of the breasts. The indications for breast reduction surgery are three-fold — physical, aesthetic, and psychological — the restoration of the bust, of the woman's self-image, and of her mental health.[1]

In corrective practice, the surgical techniques and praxis for reduction mammoplasty also are applied to mastopexy (breast lift).
