Sir:

We would like to congratulate Catanuto et al. on their work in developing a method with which to analyze the surface contour of the breast. We are excited that other experimental groups share our enthusiasm for attempting to add science to a field that previously has been approached completely subjectively.

Their work has focused on defining a Gaussian curvature parameter that they used to describe convex and concave portions of the breast surface.1,2 This type of analysis may be useful in studying patients' and surgeons' preferences in breast shape, as in our previous work.3 As they indicated in their articles, their work has yet to be validated. Our own work sought to experimentally validate our optical method of quantifying volume and surface area. Furthermore, we demonstrated that measurements of the female breast in the prone position are equivalent to those taken in the upright position, thus avoiding shadows at the inframammary fold and other limitations as documented in their articles.

In an upcoming article regarding phase II of our experiment, we use the volume-to-surface area ratio as a conceptually simple approximation of fullness or convexity of the breast. We perform a clinical application of our optical method, coupled with a series of online surveys, and we derive ideal anthropomorphic measurements and a mathematical relationship between volume and surface area for an aesthetically acceptable shape. We also quantify aesthetic features such as cleavage and asymmetry. These results are based on aesthetic feedback from plastic surgeons, cosmetic breast surgery patients, and reconstructive breast surgery patients, culminating in the first set of democratically representative and scientifically derived aesthetic values available in the literature. Previous studies relied on the aesthetic judgments of one plastic surgeon evaluator alone4 or conveyed no aesthetic judgment.5

We agree that in addition to surface area it is important to quantify the surface curvature of the breast, and we look forward to future publications from Catanuto et al. Perhaps our combined efforts will stimulate other groups to pursue scientific rigor in aesthetic plastic surgery.
