It is not a problem to treat women with breast asymmetry. In fact, many women have different size breast. For smaller volume differences, it often is corrected just by the breast augmentation procedure with equal size implants. For example, if you have one breast that is 200 grams and the other is only 100 grams, if you add 300 gram implants to both you end up with 500 grams on one side and 400 grams on the other. So in this example, without using different implants, we are reducing the difference from 50% to 20% just by adding equal volume to both.
Of course, we could always use a larger implant on one side if it would improve the symmetry of the result. Whether with saline or silicone gel implants, the options still exist to correct breast asymmetry during breast augmentation.
