The Value of 2-Dimensional Analysis of Changes in Breast Shape.

Abstract

Mazzocchi et al1 commented on the lack of objective breast measurement systems, stating that “none has been adopted in clinical practice because they are either very complex or expensive. Therefore, the evaluation of breast surgery outcomes remains subjective.” Evidently, the authors are unaware of a 2-dimensional system2 (Figure 1) that can be used in multiple clinical applications.3 Figure 1. This 20-year-old woman with minor asymmetry is seen before (A,C,E) and 2 years after (B,D,F) a breast augmentation using submuscular smooth, round moderate profile saline-filled implants (Allergan Inc., Irvine, CA). Preoperatively, the right breast was slightly larger than the left. The right breast implant was inflated to 380 cc and the left implant was inflated to 410 cc. Frontal views (A,B) show an increase in areola diameter and lowering of the inframammary folds. Right lateral photographs (C,D) show increased upper pole projection, breast projection, and breast area after surgery. The nipple level is unchanged. Left lateral photographs (E,F) also show increased upper pole projection, breast projection, and area. MPost, maximum postoperative breast projection. One-dimensional systems have been available for years,4,5 but they have a number of limitations.2 Differences are expected between individuals and between repeated (test-retest) measurements. There is subjectivity in labeling of the landmarks. Another problem with such linear measurements is relevance. The distance from the suprasternal notch to the …
