Will breasts sag if I decide to explant?

There are several factors that influence how the breasts will appear when implants are removed.  Some include the length of time the implants have been in, the volume of the implants, skin elasticity, and amount of native breast tissue.  I encourage you to see a board certified plastic surgeon near you for a consultation.  After an examination your surgeon should be able to give you more information about what you could expect after implant removal based on your individual situation.

Implant removal can lead to breast sagging. The severity depends on a number of factors, including original breast volume, ptosis, implant size, how long you've had the implants in, skin quality, etc. The breast tissue will rebound somewhat and the skin can contract. If you have saline implants you can preoperatively deflate the implants to see how the tissue is going to respond and then make a decision about proceeding with a breast lift at the time of implant removal. If you have silicone implants, then you need to have them removed first before you can assess the soft tissue volume changes. See a board certified plastic surgeon who can give you all of your options. 

The volume of the breast of course always diminishes after implant are removed and this can make someone feel more 'saggy' after such a surgery.  Everyone is a bit different and your skin elasticity depends on a few factors--  how large the implant size, aging, genetics, weight loss, how your own breast tissue has changed.  Women with great skin tone and small implants may look very much like their preop breast after implant removal.  Some of it is an unknown and many times I remove implants with a wait and see approach.  Fortunately I do not remove implants very often but in those patients, I find that few return for a lift.  In fact, no recent patient of mine has felt the need to undergo a lift even if they agree that their breasts look a little sagging after explantation.  They may feel that it is age appropriate and do not feel inclined to do anything further.
