Explant 550cc - What can I expect? (photo)

The smaller the implant and the less the amount of time it has been since placement, the greater the chance the breasts will return to their preoperative state. It is very difficult to predict breast size following explant b/c breast implants and weight fluctuations over time tend to thin tissues, cause a decrease in size, and create more droop.  
Usually removing them and performing the lift at the same time makes the most sense as some patients clearly need a lift and only want to go through one surgery.  If you are borderline, it is not unreasonable to remove the implants and then observe a waiting period of six months before the determination for breast lift is made. This will give your breasts time to bounce back and your PS time to determine what type of lift, if any, is needed.
Breast fat transfer is a great tool to balance breasts, improve symmetry, and gain up to one cup size in volume.  In general, 200 cc per breast is typically the upper limit of fat injection recommended by most plastic surgeons.  It is not that more cannot be injected; but on average, this has been determined to be the most that can be expected to live during one transfer.  Multiple transfers would be required for additional cc's.  In general, the abdomen and thighs are preferred donor sites but fat from other areas can be used.
Some of the retention rate will depend upon the amount of fat transferred, as smaller volumes will likely have a higher survival.  Occasionally, a patient can resorb a great deal of the fat despite optimal transfer procedures. I typically transfer from 250 cc to 400 cc or so per breast.  
Results are largely dependent upon the skill of the surgeon, his/her ability to remove fat without creating contour deformities, and your expectations. You would need a consultation with a board certified PS to determine your available fat stores.

You can elect to have your implants removed at any time.  Your skin will have stretched from accommodating the implants.  You will lose the volume and upper pole fullness that implants provide.  You may wish to consider a breast lift to improve overall shape.  You can also consider smaller implants.  I encourage you to meet with a board certified plastic surgeon near you to discuss your goals for surgery.

Removing 550 cc implants will take you down 5 cup sizes.  Many women are dissatisfied after explant alone because of the hanging skin, empty appearance and require a lift.  The technique I recommend explantation and lift using The Bellesoma Method.  The implants are removed, your breast tissue is reshaped creating upper pole fullness, elevated higher on the chest wall and more medial to increase your cleavage.  Vertical scars are avoided, nipple sensation (in 95%) and the ability to breast feed are maintained, if not injured during your previous surgery.  At the same time or later, fat transfers can be performed if additional volume is desired.Best Wishes,Gary Horndeski, M.D.
