The difference between the shortest distance of each sternal notch to the nipple (SN–N), that of each IMF to the nipple (IMF–N), the difference in projection between both breasts, and the volume difference between both breasts were measured using the Vectra H2 (Canfield Scientific, Inc.) 3D scanner to compare the level of symmetry between both groups^a
