Capsulectomy vs capsulotomy
One letter separates these words and a great deal separates the operations. If you take one thing from this page: -ectomy means it comes out, -otomy means it gets cut and stays in.
The short answer
A capsulectomy removes the capsule of scar tissue around the implant. A capsulotomy cuts into it to release tightness, or simply to get the implant out, and leaves the capsule in your body. Capsulectomy is the bigger operation with the longer recovery. Capsulotomy is smaller and generally regarded as more likely to be followed by the problem returning.
Schematic. Simplified, not to scale, and not a depiction of a patient or a result.
Side by side
| Capsulotomy | Capsulectomy | |
|---|---|---|
| What happens | Capsule is cut, not removed | Capsule is dissected out and removed |
| Operation | Shorter, less dissection | Longer, more dissection |
| Risk profile | Lower surgical risk | More bleeding risk; near the chest wall, more risk to surrounding structures |
| Recurrence | Generally considered higher | Generally considered lower |
| Pathology | Little or no tissue to examine | Capsule can be sent for pathology |
| Typical use | Releasing tightness; straightforward implant exchange | Contracture, rupture, suspected cancer, most explants |
Why the distinction matters to you
Three practical consequences, in the order they will affect you.
- Pathology. A capsulotomy leaves little to examine. If the capsule is removed it can be sent to a lab, which is how implant-associated cancer is found. This is the argument that matters most and it is the one least often raised in consultation.
- Recurrence. Where contracture is the reason for surgery, leaving the capsule leaves the tissue that contracted. Surgeons generally regard capsulotomy as more likely to be followed by recurrence, which is why it is not usually the plan for significant contracture.
- Recovery and cost. Capsulectomy takes longer, which increases both surgical and anaesthesia time, and both are billed. See the cost page.
The 2024 Breast Surgery Collaborative Community consensus statement defines capsulotomy, partial capsulectomy, total capsulectomy and en bloc capsulectomy as distinct procedures with distinct indications, and is the reference surgeons are working from.
Closed capsulotomy
There is a third thing you may encounter, and it is not a version of either. Closed capsulotomy means squeezing the breast forcefully from outside to rupture the capsule without operating. It was performed historically and is now generally avoided: it can rupture the implant, and manufacturers have voided warranties over it.
If it is proposed to you, ask why, and ask what happens to your warranty.
What to confirm with your surgeon
The words get used loosely, including by clinicians in conversation. Worth pinning down before you consent:
- Are you removing the capsule, or cutting it?
- If removing, are you aiming for all of it, and what would stop you?
- Will it be sent for pathology?
- If you cannot safely remove part of it, what will you do and will you tell me afterwards?
That last question is the one worth asking. Finding a capsule adherent to the ribs or the lung lining is a normal intraoperative discovery, and a surgeon who has already told you how they would handle it is a surgeon who has thought about it.
If you have read that you should insist on en bloc specifically, our page on that question explains why the consensus position differs from the advice circulating in patient communities.
