Will breast issue fluff up after an explant? I was a 32A before implants. I am now COMPLETELY flat.

The picture would be helpful in your case. This unlikely the breast will "fluff up" at this point. The breast will somewhat contract and try to regain some shape. But you're likely to have droopy breasts and loss of volume obviously. I would reevaluate your result and three months. 

Good day! It is unclear how far your are with your recovery or what other procedures your underwent. It is best to wait 3 months but improvement can be seen up to a year. Give your skin and muscle ample time to heal, retract and recover. Improved appearance after explantation can be achieved through a lift or fat transfer in conjunction or after the surgery if you are not satisfied with the results. Do not hesitate to ask your surgeon about this and discuss realistic goals and expectations. Best of luck! #RealSelf100

It is hard to believe that with a 380 cc implant that you would be flat. Give it time to heal and for the tissues to relax around them.

Yes, they will definitely change.  In my experience, the biggest change seems to come in the first 2-3 weeks and I have even seen some research that measured breast volume immediately after explant and then 2 weeks later.  Even in that short amountof time, that research measured a 15-20% increase in breast volume.  So while they will look a little weird for a while, your breasts will improve for at least 3 weeks and maybe for as long as 3 months.  I hope this helps!

Congratulations on having undergone the procedure; your concerns about the size/shape of your breasts at this point are common and understandable. Generally speaking, many patients who undergo breast implant removal are much more pleased several months after the procedure is performed;  during the initial few months after breast implant removal, the breast skin envelope tends to “contract” and take better shape. Continue to follow up closely with your plastic surgeon who will always be your best resource for advice and/or reassurance. Best wishes.

Although
breast tissue doesn’t exactly “fluff up” after explantation the way implants do
following an initial augmentation, in both cases it can take a few months to
see your final results. Implants stretch and thin the overlying skin and
tissue, so removing that support can make you feel like there’s nothing there
anymore. In reality, your breast tissue has just been a little redistributed,
and needs time to contract. By between three and six months following
explantation, hopefully you’ll see a look that’s closer to your pre-surgery
figure.

It is highly doubtful that you will "fluff up" after surgery.  Since you had a small amount of breast tissue prior to surgery, there is no reason to expect larger breast after an explant.  Best wishes!

Unfortunately, this is a little wishful.  While you may not always look exactly as "flat" as you do now - compression bandages and distortion in the immediate post-operative period make is so that it's not a precise predictor of your final result - removing 450 cc implants is, in general, a significant and dramatic change to your body.  Coupled with the passage of time, having had these implants in place is likely to leave you looking smaller than you were before the surgery.The good news is that this is not necessarily EXACTLY the way you'll look and, even though it's a shock right now, you may get used to it.  Finally, you can always consider reinserting (smaller) implants at some point in the future.Sorry about that but I hope that this helps and good luck,Dr. Alan EnglerMember of RealSelf100
