There are numerous reasons why patients come in for a breast augmentation. One of those reasons is asymmetry, which means the breasts do not match. It is very uncommon for any patient to have exact symmetry of the breasts before or after surgery, but usually the symmetry can be improved with the insertion of the correct breast implants.
The reasons why some breasts do not match can include differences in size, differences in shape, differences in height of the breasts, asymmetry of the chest wall, and differences in the nipple-areolar complex. In many patients, more than one reason for asymmetry exists.
It’s important to understand that it is uncommon for the breasts to match exactly, so it should take a significant degree of asymmetry to warrant breast implants, especially if the patient is content with the size of their breasts.
