The majority of women have a very nice and long lasting result from breast augmentation. A thin layer of healthy tissue soon forms around your new breast implant to make it part of you. This is called the capsule.
This occurs around any implanted material whether it is a pacemaker or an artificial hip. In some people this tissue may thicken with time and the term for this is "capsulation "or "capsular contraction."
Capsular contracture is the most common complication that occurs with breast augmentation and can happen at any time. It seems to be more common in the first few months after surgery, but the incidence then rises again several years after surgery.
How does Capsular Contraction occur?
At the time of the implant surgery, a pocket is made under the breast for the implant. The capsule that forms is made of fibrous tissue. Some patients lay down more collagen and scar tissue in this capsule, which naturally tends to shrink with time. In most people this may cause a slight increase in firmness of the implant, or it may only be noticed by your specialist. In some people, the capsule will tighten gradually, and squeeze the implant. This makes the breast implant feel hard, and alters the appearance of the breast. In the later stages, the implant feels very firm, and may take on a ball-like look. Capsular contracture like this usually produces pain and discomfort.
How is capsular contraction graded?
Breast is soft and looks natural (this means there is no capsulation!)
Breast is a little firm but looks normal
Breast is firm and looks abnormal
Breast is hard, painful, and looks abnormal
What causes capsular contraction?
There are probably several causes that affect some patients and not others. There are some factors that may increase the risk of capsular contracture.
The rate of capsular contraction is twice as high in smokers. Mr Turton advises all of his patients not to smoke.
Capsular contracture is more likely following an infection. It may occur following sub-clinical infection.
- Sub glandular placement
Breast implants placed above the muscle tend to have higher capsular contracture rates, versus breast implants placed behind the muscle, which is also known as submuscular placement. But remember there are other pros and cons to be taken into account in deciding on implant placement, and your specialist will discuss these.
This is a collection of blood around the implant. It can cause an inflammatory reaction, which can lead to capsular contracture. It is advisable to place a temporary drain at the time of surgery which is removed immediately before your discharge home. This removes even small volumes of blood which otherwise would be left around your implant by those surgeons that don't routinely drain.
- Smooth Surface Implants
The smooth surface implants seem to be associated with a significantly higher capsulation rate than the rough surfaced type. These rough surfaced implants were a new design change introduced over 10 years ago. The process is called "texturing". There are different ways to texture the implant. The textured implants inhibit the capsulation process and do dramatically reduce it's occurence. The textured implants also unite better to the back of the breast tissue reducing risks of a rotation of a shaped implant. Occasionaly you make get some texture-rippling form, if minor capsulation occurs with a textured implant in place.
- Previous capsulation
If you have had previous capsulation it is much more likely to occur again. There may be a genetic reason for this related to wound healing. This is unknown though.
How do you treat capsular contraction of breast implants?
My first advice is to stop smoking if you are a smoker. If there are no symptoms and the cosmetic result remains excellent you do not need to have anything done. It doesn't always progress. It is also important to know that it is not usually associated with any toxic or nasty systemic inflammatory processes.
If it causes discomfort, pain or an unwanted cosmetic result then surgery would be the best way to deal with it.
No one should undergo the previously used but now out-dated technique of closed capsulotomy (the hardened implant is manually squeezed from the outside, to tear the scar envelope, as it can damage the implant).
Open capsulotomy or capsulectomy: This involves a general anaesthetic. The previous incision is usually reopened and the capsule is either incised, or partly or totally excised.
The old implant may sometimes be reinserted. However, I will normally advise for a new implant to be used. After surgery the breasts feel softer and quite often slightly lower (the capsule has acted to keep the breasts artifically high, so after it is removed the breasts drop back to their normal position).
