Capsular Contracture Research

December 6th, 2009

No … Unfortunately I cannot report a big breakthrough in this difficult problem, but I can report that we are making progress in understanding the mechanism.

I just returned from a Scientific Summit hosted by Mentor, which is the main breast implant manufacturer in my opinion. The subject of capsular contracture was discussed in detail, and the foremost scientific mind in the world was there.

He is a scientist who has studied this problem more than anyone else in the world. He presented some fascinating findings.

First, he described a biofilm, which is a term to mean an attachment of one or more colonies of bacteria on a surface. Surprisingly bacteria have a social life and communicate via quorum sensing chemicals. When they settle on a surface of anything they are very hard to eradicate.

They might settle on the surface of a breast implant or the scar capsule.

There are probably multiple causes of capsular contracture and biofilm is probably one of them. The research is exciting. It is promising, but it is frustratingly slow.

Bacteria have two states. One is the planktonic state where they float around in fluids or even gases. The other state is when they attach themselves to a surface. When we take a culture, we are sampling the planktonic state usually. When they attach themselves to a surface they are attached stronger than superglue, and they cannot be dislodged with a culture stick.

They pile up on top of each other in the biofilm and if we add antibiotics the antibiotic cannot penetrate. The outer surface bacteria might be killed off, but the deeper ones survive and multiply.

The biofilm is well organized with the same type of bacteria living together and with spaces within the colonies for fluid to flow. The body fluid contains protein, which is their nutrient and keeps them alive.

Treatment of Capsular Contracture

October 8th, 2009

We know that breast capsular contracture is a thickening and shrinkage of the scar tissue that surrounds all breast implants. This shrinkage causes the breast implant to become compressed, hard and misshapen.

Conservative Treatment: This is non-operative treatment. The patient is advised to push the breast implant in an effort to stretch out the shrinking capsule. Any way to press firmly on the breast to cause stretch of the capsule is helpful. We do not really know how long or how hard to press, but within reason the firmer the better for as long as reasonably possible, without causing actual injury.

Surgical Treatment: This takes it one step further. Parts of the breast capsule can be removed – even removal of all of the capsule might be possible. Also cuts can be made in the capsule causing the capsule to be divided into several parts which can spread apart. This gives the breast implant more room to move around. Of course new scar tissue will grow between the parts of the capsule or all around the breast implant if the capsule has been removed. We hope that the new scar tissue will be thin and will not become thickened and shrink like the previous scar tissue, but we do not know. This is because we cannot treat the actual cause because we do not know what the cause is. I also like to replace the breast implant because of the theory that some contamination of the breast implant might contribute to the cause. If we did not replace the breast implant and the capsular contracture comes back quickly, we would always wonder if we would have had a better outcome if the breast implant had been replaced.

Causes of Capsular Contracture

September 12th, 2009

Scars around the breast implants occur in everyone who has had a breast implant. This is normal. In my explanation it is similar to the lining of your coat pocket. This lining can stretch or shrink and we do not know how to control it.

It can happen in one breast or both. It can happen soon after surgery or years later. We cannot predict who will get capsular contracture (shrinkage of the scar tissue) or capsular relaxation (stretching out of the scar tissue).

If the scar capsule shrinks it will squash and compress the breast implant. This makes the breast implant feel hard and become rounded. If part of the capsule shrinks it can push the breast implant out of position – usually upwards. The firmness can vary between a little firm to very hard. The breast implant does not move around. It stays in one position, even if you lie down. It happens in about 15 – 20% of patients if the breast implant is on top of the muscle and 3 – 5% if the breast implant is partially under the muscle.

There are no known statistics for capsular relaxation. In this situation there is too much room around the breast implant and the breast implant moves around too much. When you lie down the breast implant moves too far outwards to your side leaving the breast area empty. When you stand up the breast implant moves back to the right place and looks good. It feels very soft. In my personal observation it seems to be more likely in people who are over weight or who have lost a lot of weight.

Many people suspect that the cause of capsular contracture might be due to a sub clinical infection. In other words, the infection is so mild that you do not know anything about it. Perhaps a few bacteria are going through the bloodstream, and before your natural defenses can kill them off they land on a breast implant. Because a breast implant is not living tissue it has no defenses of its own and the bacteria can live for a while and stimulate the scar capsule to shrink. Another theory is that blood around the implant can irritate the tissues and cause contracture. I always try to do the procedure with as little bleeding as possible.

I recommend antibiotics be given in a single large dose before any dental treatment – including teeth cleaning. This is because some bacteria are often released into the blood stream during dental care, and we guess that they may have a chance to land on the breast implant. Antibiotics could perhaps kill those bacteria before tey find the breast implant. This is only an unproved theory, but it seems like a good idea.

Effects of Capsular Contracture

August 30th, 2009

Capsules are scars. They completely envelop the breast implant, just like a lining in your clothes pocket will surround a balloon if you put a balloon in your pocket.

Scar capsule can shrink. Since we do not know why, the least we can do is to observe exactly what happens.

The capsule may shrink at any time. It might happen just months after the breast implant procedure was done, and it can also happen many years after the breast augmentation was done. It can happen at any time.

The capsule may shrink in one breast or both. Obviously if it occurs on one side only then the breasts will become different.

The capsule may not shrink evenly or uniformly. By this I mean that parts of the capsule might shrink only. If the lower part shrinks, it will squeeze the breast implant upwards and cause displacement. This means that the affected breast implant will be too high and cause an unnatural bulge in the upper chest on the affected side. Sometimes, the patient thinks the breast is growing bigger. This is because she is either looking down at the bulge as it goes higher or she sees it in the mirror. Actually, it is not growing. The breast implant is just moving upwards.

We must first analyze what has happened before we can decide on the most appropriate treatment or management.

Next week lets think about what might cause capsular contracture and how frequently if occurs. In subsequent blog episodes I will also explore what our current thoughts are for treatment or management of capsular contracture around breast implants.

If you have capsular contracture please comment and add your thoughts to this blog.

Breast Implants and capsules

August 23rd, 2009

Whenever the human body is cut it heals with a scar. We see the outside scar, but there is scar inside too.

When breast implants are placed in the human breast the space for the breast implant becomes lined with scar all around, like a ball or like the lining of a pocket. We call this scar the “capsule”. It is just a fancy name for scar inside.

Capsules (scars) inside can shrink and sometimes stretch. We don’t know why and we cannot control them.

If your pocket lining shrinks and you have a balloon in your pocket it will get compressed and feel hard and become unnaturally round. This is capsular contracture.

It can also stretch out and I call this capsular relaxation.

Unequal Breasts

August 16th, 2009

When I see someone with unequal breasts several issues need to discussed.

1. First we need to analyze what is different about the breasts. It might be shape or volume or both. Measurements are taken.

2. Second it is important to find out from the patient what she wants and which breast she prefers.

3. Then we can figure out what needs to be done. Options include breast implants on one side or unequal breast implants to both sides to correct the volume differences. Then we need to discuss what can be done about the shape. A lift on one side or unequal lifts (mastopexy) might be chosen. Even a breast reduction on one or both sides might be necessary. Every combination of breast implants (breast enlargement), breast lift (mastopexy) or breast reduction might be chosen.

There are lot of different choices that can be made. They are made in discussion with the patient. Some patients want as little as possible done and some want more done. I have seen lots of people with breast deformities at my plastic and cosmetic surgery practice in Stockton, California. We are near Modesto, Tracy, Lodi and Galt.

Call us at (209) 952-2251 so that we can meet and discuss all options that are available for your situation, if you have unequal breasts.

Liposuction Abdominoplasty (tummy tuck with liposuction)

August 8th, 2009

Liposuction abdominoplasty (tummy tuck with liposuction) has become such a huge success that I hope that patients will come from further away than my usual Stockton, Lodi, Manteca, Modesto and Tracy areas.

The combination of liposuction and abdominoplasty has produced the best results for this procedure that I have ever seen. In addition complications are much less. Recovery is much quicker.

I am continually surprised to see how great the results of liposuction abdominoplasty are.

Dysport

August 2nd, 2009

Dysport is just like Botox. It works a little quicker and is a little cheaper. It is injected in just the same way as Botox. It lasts about the same amount of time – about 4 months. Currently the frown lines cost $230.

How I do Liposuction

July 15th, 2009

Liposuction is probably done differently by every plastic surgeon who does it.

1. I make punctures to create very small holes. I do not make any cuts. I do it with a round awl (a pointed object)

2. I use a metal cannula to inject quite a lot of intravenous fluids using a special pump. The fluid contains epinephrine to make the blood vessels smaller and lessen bleeding. It also contains some xylocaine to relieve the immediate pain afterward.

3. Then I move an ultrasound emitter over the skin. The skin is covered with a lubricant like KY jelly. This also helps conduction. This process pushes the injected fluid through evenly and softens the fat.

4. I suction using special cannulae attached to large syringes. When I pull the syringe plunger it locks open and creates a vaccuum. This is how I do the suctioning. There is no machine.

5. When finished BandAids are placed over the punctures, and a support garment. There are no stitches. There is likely to be some drainage for 24 hours. This lessens bruising.

6. Recovery is quick. I like the patient to be asleep for this procedure.

Looking for your comments

July 2nd, 2009

This blog is mainly about plastic surgery and cosmetic surgery in particular. I intend to put out articles that both inform you and stimulate you to add your own thoughts. Please ask questions. Please disagree as you feel appropriate.

I will answer you if you ask me about breast implants, breast lift, breast enhancements, breast reduction, tummy tucks of all types and also liposuction. As you know my practice is well known for excellent results in these areas.

I am fascinated by these subjects as well as all questions related to beauty and would be happy to enter into a spirited conversation with you. I will even digress to non plastic surgery subjects if you want me to. Let’s talk about the economy, weight loss, life changing situations, poltics, health care and art.

I invite you to participate.
