Implants initially sit high up because the chest muscles and surrounding breast tissues have not become accustomed to the implant resulting in tightness. You have to allow gravity to take effect, and overtime, natural tissue expansion will allow the implants to fall into place causing your breasts to appear more natural, softer, and rounder. Once that happens, the implant will sit directly behind the breast tissue in a natural 45:55 breast ratio, and the nipples will move up higher. While the muscle is gradually descending, it is possible for the breast size to appear different because the implant will not be directly behind the breast tissue. However, once the implant fully drops down, the implant will be reinforcing the breast tissue from the back resulting in a better quality augmentation. Please note that it is not uncommon for breasts to heal and adapt to implants at different rates. In fact, the process I described above can occur quicker in one breast over another. Unfortunately, patients don’t get to see what the plastic surgeon sees in the operating room, and as the patients gets in the recovery room, the breasts begin to swell and muscles begin to tighten. Over the next 3-6 months of recovery, the breast tissue and skin stretch and relax, the body absorbs all the fluids, and you experience the ‘drop and fluff’. If the breasts still appear different at that point in time, then you may share your concerns with your surgeon and they should be able to fix the problem. You may have to wait 3-6 months for the final results Patience is key! Please continue to have regular follow-ups with your surgeon to make sure your breasts are healing beautifully. Their recovery instructions should take precedence over all else you read here as they are better informed about your surgical details. Hope this helps.
