Metrics of the Aesthetically Perfect Breast.

Breast surgery has long been viewed as an art more than a science. However, defining and objectively measuring the ideal breast morphology and aesthetic proportions are fundamental for surgical planning and to setting the goals of surgery as well as to evaluate surgical outcomes. Despite the fact that much has been written about aesthetic and reconstructive breast surgery, there is still no real consensus about what the attributes are of an ideal breast. Moreover, there are in fact no objective standard measurement systems and guidelines to describe ideal or even normal breast shape. Though there is great variability in the perception of beauty among patients and surgeons alike due to many factors among which are age, sex, and sociocultural background, there is common agreement that beauty is a universal phenomenon that has a universal standard present across all civilizations and centuries, and that perceived beauty is enhanced and optimal aesthetics are achieved when proper measurements are made and anthropometric proportions as well as attractive harmonious ratios are respected. The current review is an attempt to summarize the most relevant information available trying to introduce some harmony in our perception of aesthetic ideals of breast surgery.
