How do surgeons grade breast sagging (ptosis) using the Regnault Scale?
#Surgeons grade breast sagging using the clinical Regnault Ptosis Scale, which measures the position of the nipple-areolar complex relative to the inframammary crease (IMF).
Grade 1 (Mild Ptosis): The nipple lies at the level of the inframammary fold. Grade 2 (Moderate Ptosis): The nipple drops below the level of the fold but remains above the lowest contour of the breast. Grade 3 (Severe Ptosis): The nipple sits at the absolute lowest point of the breast, pointing downward toward the floor. Pseudoptosis occurs when the breast gland sags below the fold, but the nipple itself remains at or above the crease.
Accurate ptosis grading directly dictates the surgical incision pattern required for correction.
