How is tissue adhesion different from a capsule?
A capsule is the organized membrane the body always builds around an implant. An adhesion is scar tissue binding surfaces that should glide past each other. Related biology, different structures, different problems.
Patients researching breast surgery meet both words and often use them interchangeably. Both are products of the same wound-healing machinery, but a capsule is an expected, structured response to an implant, while adhesions are scar bridges that form where healing tissues fused together.
Same biology, different behavior
Every implant gets a capsule — a thin, continuous lining around the device — and it only becomes a problem if it thickens and contracts. Adhesions have no such default role: they can tether skin to underlying muscle, distort a scar when the arm moves, or restrict how tissue planes glide after any operation. In implant surgery, the capsule is assessed as a structure of its own, while adhesions are more a question of scar management and mobility.
Whether a firm or tethered spot is capsule-related or an adhesion is not something touch alone can settle, and how each is treated varies by location and individual healing. If an area feels bound down or pulls with movement, point it out at a consultation with your surgeon — the distinction takes an examination, sometimes with imaging.
