In terms of body aesthetics a bit of lateral fullness or implant show on the sides can be attractive and can make an athletic body look curvier. Most Playboy playmates have some lateral fullness.
This is when the capsule at the side is closed off or tightened.
The incision used is the same as in the original surgery: areolar (nipple) or inframammary (under the breast). Mesh (GalaFlex or Strattice) may be used for additional support.
If the original surgery was transaxillary (armpit) or transumbilical (belly button) the patient is given the choice of areolar or inframammary incisions. The capsule is opened and the implant removed. The lateral pocket is tightened as above and mesh may be used for additional support. The implant is replaced (or new implant) and the incisions are closed. A drain may be placed if Strattice is used.
Strattice is often placed to correct laterally or inferiorly displaced implants.
