Thank you for the good question. Patients who are considering breast augmentation/lifting surgery should understand that this combination surgery is significantly more complex than either one of the procedures done separately. In other words, the combination breast augmentation / mastopexy surgery differs from breast augmentation surgery alone in that it carries increased risk compared to either breast augmentation or mastopexy surgery performed separately. Furthermore, the potential need for revisionary surgery is increased with breast augmentation / mastopexy surgery done at the same time. This revisionary rate may be as high (or higher) than 20%. Personally, I find that the breast augmentation/lifting procedure to be one of the most challenging of the breast operations I perform, even compared to somewhat complex revisionary breast surgery. On the one hand, when performing breast augmentation/lifting surgery we are increasing the breast size with breast implants; on the other hand, we are reducing the breast “envelope” in order to achieve the breast lift. These two “forces” must be balanced as perfectly as possible in order to achieve the desired results. Removing too much skin/ breast tissue is problematic; removing too little breast skin/tissue can also be problematic. Remember also that patients presenting for breast lifting surgery and general have lost some skin elasticity/thickness making potential incision line healing problems and/or recurrent drooping/sagging important concerns to communicate. The analogy I use in my practice is that of a thinned out balloon, being expanded with additional air; I hope that this analogy helps patients understand some of the issues at hand when performing the combination breast augmentation/lifing operation. Given the complexity of the combination breast augmentation/lifting operation and the greater risk of revisionary breast surgery needed, there are good plastic surgeons who will insist on doing the procedures separately. For me, if I see a patient who needs a great degree of lifting, who has lost a lot of skin elasticity, or whose goal is a very large augmentation then I think it is best to do the procedures in 2 stages (in order to avoid serious complications). However, doing the procedure in one stage does increase the risks of complications in general and the potential need for further surgery. This increased risk must be weighed against the practical benefits of a single stage procedure (which most patients would prefer). Conversely, if I see a patient who requires minimal to moderate lifting along with a small to moderate size augmentation (and has good skin quality), then doing the procedure one stage is much safer. Nevertheless, the potential risks are greater with a 1 stage procedure and the patient does have a higher likelihood of needing revisionary surgery. My best advice: select your plastic surgeon carefully. Make sure that he/she has significant experience achieving the types of outcomes you will be pleased with. Then, communicate your goals carefully, as well. Be careful about utilizing cup size references when it comes to communication. In my practice, the use of computer imaging and goal photographs is much more helpful. Working together you will come up with a good plan to achieve your goals. Best wishes.
