A thin 25 year old had mild scoliosis; asymmetric breasts are often caused by chest wall asymmetries. Her somewhat tubular and ptotic breasts needed to be equalized. VECTRA determined the volume difference, and we knew pre-op that she would require a left mastopexy. A 360cc implant on the right and a 300cc on the left, round smooth, accomplished our goals. She is now a large 32C.
