Capsular contracture: grades, symptoms, evaluation, and treatment decisions
Capsular contracture is tightening of scar tissue around a breast implant that may cause firmness, pain, displacement, or visible distortion. Baker grades are a shorthand, not a complete diagnosis; evaluation should document symptoms, implant condition, anatomy, and other causes before a revision is chosen.
Capsular contracture is abnormal tightening of the scar capsule that naturally forms around a breast implant. It can make a breast feel firm, look distorted, move the implant, or cause pain. Baker grades describe increasing firmness and visible change, but they are subjective and do not identify the cause, show implant integrity, or dictate one operation.13
The decision record should combine symptoms, examination, photographs, implant and operative history, indicated imaging, and a differential for new swelling or masses. “Grade III” is not enough information to choose capsulectomy, pocket change, implant exchange, or removal.
The Baker scale is shorthand
FDA summarizes the common Baker classification for augmentation: Grade I is normally soft and natural in appearance; Grade II is somewhat firm but normal appearing; Grade III is firm and abnormal appearing; Grade IV is hard, painful, and abnormal appearing.1
| Grade | Typical shorthand | What still needs documentation |
|---|---|---|
| I | Soft and natural appearing | Baseline feel, symmetry, implant position, symptoms |
| II | Some firmness without visible distortion | Whether firmness is new, focal, progressive, painful, or acceptable |
| III | Firm with visible distortion | Direction of displacement, implant condition, tissue and pocket anatomy |
| IV | Hard, painful, and visibly abnormal | Pain pattern, skin findings, swelling, mass, imaging, urgency |
The severity review found inconsistent assessment and limited reliability across methods.3 A clinician’s Grade II can differ from another’s. Preserve photographs, side-to-side comparison, pain and functional impact, and the exact physical findings rather than relying on the numeral alone.
Not every hard or changed breast is contracture
A new contour change can involve rupture or deflation, implant malposition, fluid, infection, fat necrosis, a breast-tissue finding, or another capsule process. Late swelling, a mass, or a fluid collection requires a diagnosis-specific pathway rather than automatic revision for “scar tissue.” The BIA-ALCL and capsule-SCC guide explains when sampling and pathology questions become central.
Retrieve the device card and every operative report. Record implant manufacturer and model, fill, surface, size, pocket, incision, placement date, prior infection or hematoma, radiation history, and every revision. Compare current symptoms with earlier photographs and imaging.
For silicone implants, imaging may help evaluate integrity when symptoms, examination, or screening history support it. The MRI-versus-ultrasound guide keeps rupture surveillance separate from cancer screening and capsule diagnosis.
Treatment depends on the job
Observation can be reasonable when firmness is mild, stable, and acceptable and there is no concerning finding. A symptomatic or distorted breast can lead to a revision discussion. But “treat the capsule” still does not name the operation.
Possible components include implant exchange or removal, opening the capsule, partial or total capsulectomy, pocket change, implant-size change, muscle or pocket repair, fat grafting, lift, scaffold or mesh, and pathology. Each component has a distinct reason and risk.
The systematic review found heterogeneous, predominantly low-quality evidence across surgical strategies.2 It does not support a guaranteed cure or one mandatory capsule extent for every contracture.
Recurrence belongs in consent
Contracture can recur after revision. A published recurrence rate depends on whether the population was augmentation or reconstruction, implant type and surface, pocket, infection prevention, radiation, revision technique, follow-up, and definition of recurrence. Raw percentages from a different setting are not a personal forecast.
Ask the surgeon to explain:
- the proposed contributor in this case;
- what is known and unknown about that contributor;
- which part of the operation addresses it;
- the practice’s definition and follow-up for recurrence; and
- what options remain if firmness or distortion returns.
No supplement, massage, medication, device, or surgical technique should be marketed as guaranteed prevention. If a nonsurgical treatment is proposed, request the exact product or device, regulatory status, study population, endpoint, and whether it avoids or delays an operation.
Quote the operation by components
| Component | Decision question |
|---|---|
| Implant | Keep, exchange, change size/fill/surface, or remove without replacement—and why? |
| Capsule | Open, partially remove, totally remove, or sample—which finding supports the extent? |
| Stay in place or change plane; how will old and new spaces be managed? | |
| Tissue | Is a lift, fat graft, skin reduction, or muscle repair needed for a separate problem? |
| Pathology | Which fluid, mass, or capsule specimens will be submitted and who delivers results? |
| Aftercare | Drains, garments, visits, activity, urgent contact, and recurrence assessment? |
A focused evaluation sequence
- Describe the change without grading it first. Record onset, firmness, pain, movement, shape, swelling, skin change, and functional effect.
- Recover the complete implant history. Match device cards, operations, imaging, complications, and current product labeling.
- Exclude findings that need another pathway. Keep rupture, infection, late fluid, masses, and breast-tissue findings distinct.
- Name every proposed maneuver and its job. Require a separate rationale for implant, capsule, pocket, tissue, and pathology work.
- Put recurrence and alternatives in writing. Compare observation, revision choices, removal, future surveillance, and the response if symptoms return.
The decisive question is not “What grade is it?” It is “What exact finding is causing pain or distortion, which operation component addresses that finding, and what evidence and follow-up support the plan?”
