Implant pocket is the most important determinant of outcome and is described by the relationship of the implant to the pectoralis muscle on the chest. The “pec” muscle is a flat fan-shaped chest muscle connected to the front of the chest on three sides (collar bone, outside border of the breast bone, and along the ribs near the lower part of the breast). The muscle is not connected to the chest wall on the side toward your armpit (you can pinch the muscle between your fingers on the side) as it spans over the armpit to connect the chest to your upper arm. Placing the implant above this muscle is called subglandular or prepectoral. Placing the implant below the muscle is called submuscular or subpectoral, and can be further differentiated by being completely under the muscle (total submuscular), or partly under the muscle (dual-plane). When an implant is placed below the muscle, the procedure is more painful and you may need more pain medication. However, for most women, the pain is temporary and there is no difference in pain long term. By changing the pocket, you can change the overall breast look as well as the relative short and long term risks and benefits of the procedure. During your consultation from the breast implant specialist, Dr. Albright will help you decide which implant pocket is best for you.
