As a Plastic Surgeon, I spend most of my time improving/enhancing/correcting issues on paired structures. Breasts, eyelids, arms, legs etc… In all of these cases, the patient and I are in pursuit of perfect symmetry. Problem is, as humans, we are just not perfectly symmetric.
If you divide the body into a right and left side, and look closely, you will notice some differences in every body part. One side of the face is longer, an ear protrudes more, a breast is bigger or lower or rounder. We just aren’t even.
And so, as a Plastic Surgeon, my goal is to come as close to “perfect” symmetry as possible.
