Mastopexy (Greek μαστός mastos “breast” + -pēxiā “affix”) is the plastic surgery mammoplasty procedure for raising sagging breasts upon the chest of the woman; by correcting and modifying the size, contour, and elevation of the breasts. In a breast-lift surgery to re-establish an aesthetically proportionate bust for the woman, the critical corrective consideration is the tissue viability of the nipple-areola complex (NAC), to ensure the functional sensitivity of the breasts for lactation and breast-feeding.
The breast-lift correction of a sagging bust is a surgical operation that cuts and removes excess tissues ( glandular, adipose, skin), overstretched suspensory ligaments, excess skin from the skin-envelope, and transposes the nipple-areola complex higher upon the breast hemisphere. In surgical practice, mastopexy can be performed as a discrete breast-lift procedure, and as a subordinate surgery within a combined mastopexy–breast augmentation procedure.
Moreover, mastopexy surgery techniques also are applied to reduction mammoplasty, which is the correction of oversized breasts. Psychologically, a mastopexy procedure to correct breast ptosis is not indicated by medical cause or physical reason, but by the self-image of the woman; that is, the combination of physical, aesthetic, and mental health requirements of her Self.
