How to estimate size after explant and lift? (Photo)

Unfortunately, you have not told us your bra size.  If you are 32 or 34, each 100 cc of implant removal corresponds to 1 cup size change.  If you are 36 or 38, each 200 cc of implant removal corresponds to 1 cup size change.  From this, you can determine what your bra size will be after removing your implants.  The technique I recommend is 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.  Later, fat transfers can be performed if additional volume is desired.      Best Wishes,Gary Horndeski, M.D.

To best estimate the amount of natural breast tissue you have I encourage you to meet with a board certified plastic surgeon near you.  The longer that an implant is in place and the larger the implant volume, the more effect it will have on natural breast tissue.  Weight gain or loss can also impact the amount of natural breast tissue that is present.

Thank you for the question.  Nothing will replace in-person evaluation when it comes to providing you with good advice.  One way to decide whether or not you will be pleased with the results of breast implant removal surgery alone would be to ask your plastic surgeon to show you photographs of what he/she anticipates your breasts will look like after the procedure.
Generally speaking, what your breasts will look like after explantation depends on several factors such as: the quality of skin elasticity (the better the elasticity the better the skin will bounce back), the size of the implants used (the larger the implant the more trouble you may have with redundant skin), and the amount of breast tissue present at this time (which may have changed since the time of your breast augmentation).
Life experience since your breast augmentation procedure, such as pregnancy or weight gain weight loss, will potentially influence the factors discussed above. If you take these factors into consideration and apply them to your specific circumstances you may get a good idea of what to expect after the implants are removed.
 Patience is definitely indicated after removal of breast implants; it will take many months/year for the skin to “bounce back” and for you to see the final appearance of the breasts.
In "borderline" cases where there is doubt whether breast lifting is necessary or not, I advise patients to undergo explantation only and to give their breasts the benefit of the doubt  before deciding whether breast lifting would be beneficial.  
 I hope this helps. Best wishes.
