Hanging of the breast is called breast ptosis in Latin. A breast is essentially sagging when there is a disproportion between the volume of breast tissue and the surface area of the skin mantle. Both the sagging of the skin with age and the loss of breast tissue after pregnancy or weight loss lead to breast ptosis.
In a juvenile breast, the nipple is located about five to seven centimeters above the underbust crease or at the level of the middle of the upper arm. As a further guide, the distance from the jugulum to the nipple is usually measured. This distance is about 21 to 23 centimeters for a teenage breast.
Another characteristic of a sagging breast is deviations from a balanced height ratio between the upper and lower halves of the breast, corresponding to 45 percent to 55 percent (Mallucci P, et al. Population analysis of the perfect breast: a morphometric analysis. Plast Reconstr Surg. 2014 Sep;134(3):436-47.). The degree of expression of breast ptosis is divided into three grades according to Regnault. Somewhat more accurate is the indication of the height between the nipple and the inframammary fold in centimeters (Kirwan L. 2002. Aesthet Surg J). Breast ptosis can be corrected by a breast lift.
