Will breast tissue eventually fill back in after explantation? 3 days post-op.

Thank you for your question. Seems like you've been through quite a lot! While the skin may contract a bit, your breast tissue will likely not return. The only way to add more volume (or redistribute the volume you have) is through a lift, or with another implant or fat grafting. I would give things some time to heal, however - at least 3-6 months and then see how you feel at that point. Best of luck! 

You are very early in your recovery, but the breasts will most likely not gain volume.  In fact, you may look a little flatter once swelling decreases.  The skin of the breast will probably contract some.  If after you have healed you are unhappy with the look, you can consider fat grafting, a lift, or an implant at that time.

The breasts will remain flat and maybe a bit more as the swelling subsides.  The only way to add moe volume is to either inject fat or put in another implant. You may benefit from a lift as well.
