What is capsular contracture?
Capsular contracture can happen to breast implants over time.
All implants have a capsule that forms around them.
A capsule is made up of scar tissue and it is the body’s reaction to the implant.
It is a normal reaction and it happens to all implants, no matter where they are in the body – in your hip, or your heart, in your chin or your eye.
The capsule is normal scar tissue and is nothing to worry about.
Over time the capsule (like all scar tissue) tends to contract and it is the capsular contracture that is the problem.
The problem is not with the implant, the problem is with the scar tissue that forms around the implant.
If an implant is solid like a hip implant or a chin implant, the contracture of the scar tissue does not have much of an effect on the implant.
However if the implant is soft, like a breast implant, then the contracture does have a constricting effect on the implant and this is what causes the problem.

Capsular contracture is a progressive condition and over time, the implant can start to feel hard, then it can start to look ’rounded’ and then it becomes uncomfortable.
That is the natural history of capsular contracture.
Capsular contracture is graded according to the following scale (Baker classification):
- Grade I capsular contracture: you cannot see or feel your breast implants (i.e. everybody has at least a Grade I capsule)
- Grade II capsular contracture: you can feel but you cannot see your breast implants
- Grade III capsular contracture: you can feel and see your breast implants
- Grade IV capsular contracture: your breast implants feel painful
No matter what the shape or profile of your implant, when the scar tissue contracts around it, it becomes spherical, like a ball.
This can make your breast look unsightly and feel uncomfortable.
For whatever reason, capsular contracture often only happens on one side which can lead to your breasts looking asymmetrical.
Capsular contracture is a progressive condition but it is usually very slow to progress.
Capsular contracture does not need to be treated and it is your choice whether you have your implants replaced.
Prevention of capsular contracture
There are a number of potential causes for capsular contracture that we work hard to avoid in order to minimise the risk of capsular contracture.
Small amounts of infection around the breast implant or a collection of blood around the implant (haematoma) can predispose to capsular contracture.
We do everything we can to minimise the risk of infection with breast implants and are very careful to control any bleeding at the time of surgery.
Fortunately the risk of infection and haematoma are very low after breast implant surgery.
Using textured rather than smooth breast implants and placing the implants under the muscle has also been shown to reduce the risk of capsular contracture, but probably the most significant thing that you can do to reduce the risk of developing capsular contracture is to use polyurethane foam coated breast implants.
These implants have not been widely adopted in the U.K. but have a been used in hundreds of thousands of women worldwide.
They are controversial and like most things, they have pros and cons and you can read my blog post about them here.
I think they are good implants and I use them a lot because I do not want my patients to have problems with capsular contracture in the future, but I discuss the risks and the benefits with everyone because ultimately it is your decision as to what type of implant that you have in your body and you need to be comfortable with the choice.
Treatment of capsular contracture
The good news is that capsular contracture is not a harmful condition and it is perfectly acceptable to leave it alone.
It does tend to be a progressive condition and so will probably get worse, but progression is usually slow and it can take many years for it to develop.
The bad news is that the only effective treatment of capsular contracture is surgery.
There are no tablets or creams or any other cures that have been shown to be effective in the treatment of capsular contracture.
Surgery involves removing the capsule (capsulectomy) and replacement of the breast implants.
This surgery is more extensive than the original surgery to insert the breast implants and so it is more expensive and because it is more extensive, it is more traumatic and creates more scar tissue.
Because capsular contracture happens in the first place because of scar tissue forming around the implant, another capsular contracture happens quicker after a capsulectomy and implant replacement than it does after the initial breast implant operation.
For this reason, my advice to patients is always to wait as long as possible before undergoing a capsulectomy in order to minimise the number of operations to your breast in your lifetime.
The type of surgery that can be performed on the capsule could be:
this is removal of the capsular tissue and can be partial or complete. This can be quite an extensive operation and there is a risk of bleeding that can form a haematoma and cause the breast to swell up. This would require another visit to the operating theatre to evacuate and wash out the haematoma.
this is scoring of the capsule to release it and allow it to expand if a new implant is being placed (note, if you are changing from a silicone to a polyurethane implant, then a total capsulectomy should be performed to allow virgin tissue around the polyurethane implant to grow in to it). This is usually performed in cases where there is only a mild form of capsular contracture otherwise capsulectomy would be needed.
this involves using the thick tissue of the capsule to suture together areas of the breast pocket to manipulate the shape and appearance of the breast.
This is usually required in situations where the implants are being replaced because they are not sitting well in the breast pocket.
They could be:
- Too high
- Too low
- Too far out to the side
- Too close together in the middle (synmastia)
It may also be required if the implants are being replaced for smaller implants because the breast pocket may be too big.
The other situation where capsulorrhapy is useful is where there is a poor definition of the inframammary fold. The inframammary fold is a very important feature of the breast as any surgeon who performs breast reconstruction after mastectomy will tell you.
A very important part of breast reconstruction is to recreate the inframammary fold and these techniques used in breast reconstruction can be transferred to cosmetic breast surgery if needed.
The inframammary fold is the part of the breast where a wire of a wired bra would sit. If you look at the shape of a breast, it is not simply a dome on the chest wall. In the upper part, there is a smooth transition from the upper chest to the upper pole of the breast, but it is important to avoid this shape in the lower pole.
The lower part of the breast has a defined and crisp fold which gives a natural shape to the breast as it sits on the chest wall.
This is important, not only so that the wire of a wired bra sits comfortably, but also to give a normal and natural look to the breast. If there is blunting of the sharp angle at the inframammary fold, then the breast lacks aesthetic appeal.
It can be difficult to recreate the inframammary fold in situations where it is not well defined, either following breast enlargement surgery or as a result of your natural breast shape. This can involve a combination of internal sutures and capsulorrhaphy.
