What is the difference between the capsule and the pocket in relation to breast implants, or are they the same thing?

Great question. The pocket is the physical space where the implant is located. It can be above or below the muscle. The capsule refers to a layer of scar tissue that surrounds the pocket. Essentially, the capsule is the inner wall of the pocket. Capsular contracture refers a situation where the capsule becomes abnormally thickened.

This is an excellent question and comes up often. The breast pocket and capsule are essentially the same space.  You first make a pocket during surgery into which you place the implant, then the body forms a thin capsule (normal scar tissue) around the implant as the pocket heals from the surgery. all breast implants that heal normally will have a thin capsule around them.

The capsule is the scar tissue around the implant.  The pocket is the area the implant sits.  Pocket repairs are difficult, but necessary, in most revision breast surgeries.  Implant size and shape are also critical to getting a beautiful long lasting result.
