Are polyurethane breast implants difficult to remove and replace?

The old polyurethane implants will be removed with the capsule. This is not particularly difficult to do.

They can be.  As with any procedure it is difficult to state absolutely what the outcome will be.In the case of polyurethane implants such as the "Meme" implant, the polyurethane was a shell around a silicone gel implant.  If the polyurethane resorbed or became otherwise separated from the implant and the implant did not remain fully intact, then (and as with other silicone gel implants) removing the gelatinous material can be difficult.  Ideally, if the implant is removed with an intact scar tissue shell (the capsule) then it should come up in a fairly straight-forward manner.  That can be more difficult, however, if the implant was under the muscle (the deeper portions of the capsule may be adherent to the ribs).In short, it is possible to remove the implants but it can be difficult.I hope that this helps and good luck,Dr. Alan EnglerMember of RealSelf100
