Breast ptosis is defined by the inferior descent of the breast relative to the inframammary fold. The most common classification accepted by plastic surgeons uses the nipple relative to the inframammary fold to determine the severity of ptosis. The severity of breast ptosis is classified into: Grade 1 - Mild - Nipple position descends to the level of the inframammary fold. Grade 2 - Moderate - Nipple position descends to a position below the inframammary fold but remains higher than the lowest edge of the breast. Grade 3 - Severe - Nipple position is located on the most inferior aspect of the breast and often is pointed to the ground. The severity of ptosis will often influence the choice of breast lift technique recommended by a plastic surgeon.
