Hello and thank you for the question. Yes, both can be done together, given you are healthy and have no risk factors that would preclude you from having additional surgery. Question: why are you removing vs replacing the implants? Fat transfer to the breasts is a possible option and works well in certain cases. 1. you only want a small volume of added fat to the breasts. Larger volumes tend not to work and doesn't give the same fullness and size that a breast implant would. It is best reserved for modest volume corrections 2. you must account for some fat loss. Generally, for brazilian butt lifts, about 80% of the fat remains long term. In the case of breasts it is much less, around 50%. So you need to somewhat over correct the breast knowing in advance that about half will be gone. It is unusual to need another breast lift in 6 years, unless it wasn't a full anchor type lift the first time? Sometimes, weight fluctuations, repeat pregnancy can cause the breasts to sag again. Doing a full anchor, although it does leave scars, is the best option to lift the breast in the most permanent manner. For some examples of my before and after patients, please follow me on instagram: @bennettyangmdThis surgery typically takes 2-3 hours to complete, and requires about a week off of work and a month out of the gym. Before having any surgery, you should be healthy, non smoking, and make sure any health conditions are being managed by your primary care md. Best to you.
