Under normal conditions, a breast implant does not fall lower than the bottom of the breast’s attachment to the chest or what we call the inframammary fold. There are times however when a woman’s breast is a little ptotic or droopy and we will intentionally position the implant lower in the chest as this can provide a little extra lift. Other times the implant can fall well beyond the fold and create a condition called “bottoming out.”
It sounds as if your implant has fallen beneath the fold. This can be repaired but generally requires surgery. Your surgeon would perform this from inside the breast by temporarily removing the implant and repairing the opening to reconstruct the inframammary fold. The implant is then immediately replaced and the incisions are closed. One question is have you had a MRI examination? It is generally recommended that this be performed periodically for women who have silicone gel implants to document the integrity of the implant. You would want to be assured that the implants are not ruptured.
