Basic Facts on Breast Implants
It is important
to understand that the outer shell or envelope of all breast
implants is made of silicone. However, the actual filling substance
can differ giving rise to various types of breast implants including
saline (salt water), pure silicone gel which is divided into simple
or cohesive gel (Silicone implants are widely used in Europe and
will most like return to the U.S. market by 2004)
Silicone gel implants are currently the most common type used throughout the World. In Europe current sales figures show a distribution of 70% silicone, 15% saline, and 15% for alternative fillers such as Hydrogel and Soya oils. As modern silicone gel implants have been available since 1963, surgeons therefore have over 35 years of experience with these types of breast implants. This is more than any other type in use. Evolution has brought changes and improvements over the years with the introduction of textured surface envelopes made of newer formulations designed to minimize the "bleed" or diffusion of what is usually tiny amounts of the silicone oil fraction of the gel contents.
Importantly the standard silicone gel by most accounts, arguably "feels" the most natural of all breast implants. This is probably as a result of the inherent smoothness of the silicone gel content
A Few Facts on Silicone.
Many women
considering this type of surgery will no doubt have heard of
frightening stories about silicone toxicity or autoimmune/connective
tissue disease, due to gel "bleed" or migration. As a result, breast augmentation has, in the last 8 years, received much unfavorable publicity mainly through the irresponsible actions of the media whereby, regardless of the facts, claims have been made with respect to silicone safety. Undoubtedly, most of these stories began to attract attention after the American Food and Drug Administration (FDA) in January 1992 imposed a ban on the use of silicone gel breast implants. The FDA concluded, "there was no evidence that silicone gel filled breast implants are unsafe, but there was insufficient evidence to prove safety". All the above was a result of pending law suits against the manufacturers of breast implants from women who had implants and were now allegedly suffering from a whole host of symptoms from a disease process arbitrarily termed "silicone related autoimmune disease". In fact a search of court records in America has revealed that no less than 216 separate complaints or symptoms have been filed in association with gel filled devices(a number unheard of with any other disease process or condition!)
Since this time there has been much activity and debate within the medical community to try to ascertain whether silicone gel breast implants are safe. To this end there have been many numerous statements issued and conclusions deduced. In summary some of these are:
1. In January 1992 the Chief Medical Officer informed surgeons and doctors that the Department of Health felt no reason existed to withdraw implants from use based on scares in the USA.
2. In April 1994 a Specialist Committee set up by the Department of Health, concluded that no scientific evidence existed which connected silicone implants with either connective tissue or autoimmune disease.
3. There have been claims that silicone causes a totally new syndrome. These have been based on anecdotal reports and therefore no studies exist to substantiate this. In response to these the American College of Rheumatology (ACR) issued a statement in October 1995 based on research studies involving over 87,000 women. This read "silicone implants expose patients to no demonstrable additional risk for connective tissue or rheumatic disease" and " there is no reason to discourage women from considering breast implant surgery on the basis of acquiring or worsening a connective tissue disorder.
4. At least 22 studies have been published from all over the world in the last few years, encompassing over 500,000 women in these studies, and none could find a relationship between so called "silicone autoimmune disease" and breast implants.
5. The finding of silicone in bodily fluids should be viewed in perspective; silicone is found abundantly in our environment and indeed probably in most people. Our contact with silicone is extensive throughout all of our lives and it is used widely in medicine. Silicone is used as a lubricant in every disposable needle, syringe and intravenous tubing. Silicones are used in lipstick, suntan lotions, food processing, skin creams, hair spray, and cosmetics. Over 1000 medical products use silicone as a component or in the manufacturing process including artificial heart valves, joints, and pacemakers.
6. In July 1998, the Department of Health published its findings and conclusions following a committee review set up to investigate the safety of silicone implants. The committee which comprised mainly of scientists and academics concluded that it found no scientific evidence linking silicone implants with disease( the full 36 page report can be obtained from Silicone Gel breast Implants Independent Review Group on 0207 972 8000 or it can be downloaded on the internet on http://www.silicone-review.gov.uk)
In conclusion to these statements, it would be fair to accept that some women who have had Breast Augmentation surgery, may have subsequently developed at some point in their lives a connective tissue or autoimmune disorder. However as these disorders arise fairly commonly in individuals in the general population anyway, regardless of whether they have had breast implant surgery or not, is it not possible that they may have become ill anyway? This type of question can only be answered by careful statistical analysis and examining groups of individuals who have had silicone implants and then comparing them to similar numbers and types of individuals without breast implants. If it then appears that the group of women with silicone implants suffers a higher number of individuals with autoimmune diseases then a causal link can be established. However, at the moment, after examination of all the relevant data, it seems safe to say that there is no conclusive scientific evidence that silicone materials in breast implants increases the risk of connective tissue diseases or for that matter breast cancer.

What are the alternatives to Silicone Gel?
Saline Breast Implants
Saline Implants are the mainstay of Breast augmentation in the United States. (This may very well change once silicone is re-introduced for aesthetic breast surgery by the FDA in the upcoming year. Although the shell are still the made from silicone the filler is sterile saline, and if leaking were to occur the net effect would be the bodies absorption of salt water. Dr. Klapper will discuss at the time of your consult the pros and cons of Saline Breast Augmentation.
Are there different shapes and consistencies of breast implants?
There are different shapes and types of
breast implants; both silicone and saline. Traditionally, all
implants have been round. The majority of all implants currently
used are still round with use of anatomic implants as deemed
necessary to meet the individual patients goals.
How do I choose which size of breast implant is the best for
me?
Implants come in a wide variety of sizes and it is possible for any woman to comfortably carry a variety of sizes on her chest. Most women have a rough idea as to how big they may want to be in terms of bra sizes. The objective during the examination is to determine which size of breast implant will give the desired appearance. As you can imagine different size implants in different framed women gives different results. The secret is to choose a size that will give you a more balanced, proportionate look overall and more inline with your desires. At the time of your consultation Dr. Klapper will take specific measurements of your breast and chest in order to try and determine which size would be suitable for you. In addition to these measurements he will take into consideration your vision of your ideal breast size.
It is important to understand however that ultimately, the limiting factor in choosing implant size is the space available beneath your breast. Its important to remember that as the volume of any breast implant increases, then so does its width. Therefore if you choose an implant that is excessively large, the edge of the implant may then extend around beyond the breast and potentially even under the armpit. This would be undesirable for most people. In addition the potential for rippling (see below) and other long-term adverse problems increases.
The vast majority of women however have a realistic outlook of what they wish to look like, and therefore it is not often that a surgeon cannot deliver the desired expectations to his patient.
Do Breast Implants cause Breast Cancer?
There
is no evidence that silicone in breast implants causes cancer in
humans.
Does a Breast Augmentation affect the means to detect Cancer?
Perhaps the most significant concern over breast
implants is the possibility of delayed detection of breast cancer
with silicone and saline filled breast implants. Both of these are
radiopaque, meaning the implants obstruct the breast tissue viewing
to varying degrees on mammogram. Mammography techniques however have
improved over the last few years enabling the radiographer to
minimize the amount of breast that is hidden by the implant. It is
important however to realize that 10-20% of breast cancers are
invisible to x-ray, and therefore most breast cancers are still
being discovered by self or physical examinations. In this respect,
interestingly enough, some clinicians feel that the implant can
actually increase the ease of palpation.
A woman with breast implants should be on the same schedule of routine mammography as all other women. The radiographer should be informed that she has implants and therefore special displacement (Eklund) views will be required for proper radiological evaluation.
In conclusion, implants make the job of the radiologist more difficult but they do not prevent him from carrying it out.
How long do breast implants last?
Like all man
made products, breast implants do not last forever. Despite being
very robust and resistant to even extreme pressures, they are
susceptible to daily wear and tear over time. What this means in
simple terms is that the outer shell or coating of the implant
eventually wears thin and ultimately disappears. If this happens
then the contents of the implant leak out. This is usually termed
disintegration, leakage or rupture of the implant. Clinically
however this may be difficult to spot. Occasionally one may detect a
slight flattening of the breast or an alteration of the shape, but
this may only be very slight and hardly noticeable. Capsule
formation (see above) is the main reason that ruptures of an implant
can sometimes be tricky to detect. As previously stated, a capsule
forms a type of "biological bag" encompassing any breast implant. Should leakage of the implant therefore occur, the contents will still be contained in the same location by the body's own bag or capsule. Despite being difficult to detect clinically however, thankfully an ultrasound scan will most times be able to accurately assess the condition of any implant when necessary. There are many quoted figures as to how long ultimately any implant lasts before disintegrating. An average figure is probably in the order of 20 years. There are however variations in the wear and tear amongst different individuals. A women therefore who subjects herself to extreme physical exercise for many hours a day on a regular basis with resultant excessive movements of her breasts (i.e. aerobics instructor, marathon runner, regular horse riding etc.) will naturally subject her implants to more wear and tear over a given period of time, than someone who does very little exercise. In the first situation it would be reasonable to assume that the implants may disintegrate sooner than in the latter case.
In order therefore to have a proper assessment of the state of your implants it is best advised to have your implants examined by a specialist on a regular basis from about 10-15 years after your operation and an ultrasound performed as necessary.
What does the operation involve?
The main
principle in the operation of Breast enhancement surgery is the
creation of a pocket behind the breast which will accommodate a
breast implant. There are however a number of details in the
approach to this surgery which one needs to understand beforehand.
What kinds of Incisions are there?
The infra
mammary incision,is made under the breast at the fold or crease
line. The incision is about 4 cm in length. This is the most common
incision, and the natural fold of the breast usually hides the scar
quite well. It will probably always be covered by any clothing-even
the smallest of bikini tops. Because the incision gives immediate
access to the space where the implant will be placed it is possible
to very accurately create the size and shape of the pocket for the
implant, and the carefully control the position of the implant
within that pocket.
Another method is the peri-areola incision, which is made around the edge of the areola (the darker skin around the edge of the nipple). The disadvantage is that the scar is not hidden by any folds, and subsequent scarring may interfere with milk expression in breast-feeding.
The third method is the axillary incision, which is made in one of the crease lines of the armpit. This is used less often because it is more difficult to get proper placement of the implant in some patients, and if there is a problem in the future, an additional incision on the breast may be required. Although some patients thinking about this surgery may believe this approach is the least conspicuous, in truth this may not always be the case, particularly in light of sleeveless open type clothing which expose the armpit area quite readily and frequently.
Regardless of where the incision is placed it is important to remember that a scar will always be present. The scars normally settle quite well and become less conspicuous with time. However no surgeon can ultimately predict the appearance of any particular scar.
Where do you place the implant? In front of or behind the muscle?
There are two locations or pockets
made where the implant may be placed; the sub glandular (in front of
the pectoralis muscle) and the sub muscular (behind the pectoralis
muscle). The pectoralis muscle is the chest muscle that is commonly
developed in body builders.
Sub muscular placement increase the padding overlying the implant offering more coverage and camouflage to the shape of the implant. This is particularly helpful in women bearing very little or no breast tissue at all. By providing this extra padding in these circumstances, one then substantially decreases some of the adverse effects on the appearance mentioned above. Another advantage is that mammography has been reported to be slightly more effective. The disadvantages are that there may be a bit more pain, or discomfort, after surgery and that the breast will move with certain actions of the muscle.
In the U.S. the sub glandular placement is probably the most common location used. The disadvantage is that the outline of the implant may be more prominent or visible in very slim women. In these situations one can therefore sometimes detect a "step-off" appearance or "stuck-on" look of the breasts on the chest. In these situations you will be advised to have the implant placed sub muscularly.
There are however some breast shapes that are better suited to the sub glandular approach. These women typically have breasts that at one time were much larger than the present. When there is a very large volume decrease and there is little or no shrinkage in the size of the skin envelope surrounding the breast tissue, then the shape approaches that of an "empty bag". Under these circumstances it is sometimes better to place the implant in the sub glandular position in order to allow the implant to fill out the skin envelope of the breast.
In the event that the skin envelope has stretched to the point where the nipple is below the breast fold, it may be necessary to reposition the nipple upward again and reduce the size of the skin envelope by means of an uplift or mastopexy. Again, this will be determined at the time of the consultation
The decision, as to which location the implant should be placed in your case, will be discussed at the time of the consultation.
What type of anesthetic is used and how long does the surgery take?
The operation is mostly performed
under general anaesthesia and is done on an outpatient basis.
Is breast augmentation painful?
Some
pain will be experienced following a Breast Augmentation. It is
always difficult to quantify how much pain any one individual will
experience. Whilst some women find this procedure extremely painful
others report very little pain postoperatively. Placement of the
implant behind the pectoral muscle is associated with a greater
degree of pain, as it is necessary to cut the muscle in order make
space for the implant.
It would be fair to suggest that most women experience a moderate degree of pain for the first five days, which will require regular painkillers. After a week however most women report a considerable improvement in their symptoms and in fact do away with any regular painkillers.
What happens after breast augmentation surgery?
Your breasts will be somewhat swollen and bruised
postoperatively. This usually settles in about two to three weeks.
Sometimes swelling may be slightly different between the two sides.
This is normal and settles with time. However if a great difference
develops between the two sides then you must contact us for advice.
Following a Breast Augmentation, the breasts may appear to be placed quite high up. This is also normal. During the first two months postoperatively the implants will gradually lower and settle from the effects of gravity into a more natural position. Do not be alarmed if one side settles quicker than the other, as this sometimes occurs.
Following the operation you will have a light dressing in place which will need to be kept dry until your follow-up appointment. At this time the wound inspected and lightly cleaned. There are no stitches to remove, as these are internal and dissolvable. Always remember to read and follow the postoperative instructions that will be given to you.
What kind of after effects should I expect?
Changes in nipple and breast sensation(feeling) can
occur. Some patients may loose sensation entirely, others report
only a slight decrease, and some even report heightened sensation.
In the majority of cases where sensation changes occurs, these are
only temporary and soon recover. The recovery period can sometimes
take up to 18 months to complete. In a small minority of patients,
however, permanent loss of sensation may occur.
Breast Feeding can proceed following a breast augmentation providing of course that you are able to produce enough milk in the first place. You must understand that regardless of whether you have implants or not, all women cannot breast feed satisfactorily.
Pregnancy: Should you become pregnant following your operation then your existing breast tissue will be subjected to the normal hormonal influences of this period and therefore your breast will enlarge and the skin will stretch accordingly. Likewise, once the pregnancy and any associated breast feeding ceases, your own breast tissue will then shrink down. It is impossible to predict to what degree these changes will occur; however, the breast implant volume will remain the same throughout these.
Palpation of the implants may occur in thinner women following breast augmentation. In these situations the implants are more likely to be felt at the lower part of the breast near the fold. Again this has no medical implications, although women who do not bear this in mind may suddenly become worried about feeling a "lump" in their breast. In any instance of uncertainty it is always best to contact your surgeon to have this examined.
What are the scars like ?
Scars are not
a complication but a normal event after any surgery. Thankfully the
scars in a Breast Augmentation operation are short, being about 3-4
cm in length. You should always expect these to be red, raised,
lumpy and even itchy to begin with but with time they should fade
and flatten. This is the natural evolution of the healing process.
However it is important to keep in mind that this may take up to two
years to complete. Daily massage of the scars during this time
period is advised to expedite and facilitate this process. You must
understand however that no responsible surgeon will ever be in a
position to predict any scars ultimate appearance.
What could go wrong?
All surgery
carries some uncertainty and risk. When a breast augmentation is
performed by a qualified Plastic Surgeon, complications are
infrequent and usually minor. Still, individuals vary greatly in
their anatomy, their physical reactions, and their healing
abilities, and the outcome is never completely predictable. These
include infection, hematoma, and skin necrosis. Infection can occur
despite our normal routine of administering antibiotics at the time
of surgery as well as post-operatively. This happens about one
percent of the time. Signs such as pain, redness, swelling, or
fever, following augmentation should be reported immediately to the
hospital. Infection not reported could easily compromise the success
of any surgery. If infection was to be serious and fail to respond
to antibiotics, removal of the implants would be required and
replacement would not be effected until such time as the infection
had cleared.
Bleeding, as a result of a leak in a blood vessel will give rise to swelling and bruising of the breast. If this is slight then your body will be able to absorb it in time. If it is significant (termed hematoma, and occurs 1% of the time) then it may be necessary to drain this. Your surgeon will be able to assess this.
Skin necrosis or skin decay occurs when there is not enough blood to supply the skin. This could happen if the surgeon were to select an implant size too that was too large for the pocket created. This is extremely rare and in fact, Dr. Klapper has not experienced this problem and nor does he expect to.
Capsular Contracture (Hardening)?
This
is the most common complication of breast implants. A capsule or
capsule formation is a layer of scar tissue that normally forms
around any artificial material placed in the body. It is important
to realize that this is the natural response of the body to foreign
material. Most times this capsule is so soft that it is virtually
undetectable and therefore does not affect the implant in any way.
Capsular contracture or hardening occurs when this layer of scar
tissue shrinks around the implant, squeezing it so that it starts to
feel firm, or in some cases, quite hard. Most capsular contractures
experienced today stem from the smooth shell silicone implants
placed some years ago. The capsule contracture rate in the past was
30-35%.
With the onset of textured shell implants, the problem of capsular contracture has been significantly reduced, now being between 6-8%.
The cause of capsular contracture is not totally clear, but seems to be multifactorial. It is important to realize that there are degrees of contracture and that the majority of women, who do develop this hardening, develop it only to a mild extent. In the minority however, it may be severe enough to be bothersome, even painful and may cause distortion of the breast. The condition may occur in one or both breasts and to a different degree either side.
It may develop any time, even years later although it is most likely to happen in the first 3 years after surgery. Unfortunately at this time there is no effective way to prevent capsular contracture if it is going to occur. However as mentioned previously, encapsulation is no longer the problem that it was. Having mentioned all the above, it is important to note that capsular contracture is not in itself a health risk other than its possible interference with mammography.
There are two ways to reduce or relieve the firmness of a contracture. These are the closed and open capsulotomy. In the closed capsulotomy, the firm implant is manually squeezed tightly from the outside, in an attempt to disrupt or tear the scar envelope. When successful the result is instantaneous and the implant immediately feels soft. The tear resistance of the scar envelope however varies from woman to woman. Some tear easily but in others the scar is so tough that it cannot be torn. In others, only a partial tear is possible which can lead to a small outpouching of the implant, with a resultant unsightly appearance. A closed capsulotomy may also result in bruising, bleeding, or even rupture of the implant itself. If rupture occurs then you will need surgery to remove and replace it. In light of these unpredictable outcomes, closed capsulotomy is infrequently done.
The other method, which is much more controlled and thus the preferred method, is the open capsulotomy, performed under general anaesthesia. In this procedure the old incision is reopened and the thickened capsule is removed or loosened. The implant is then reinserted again into the breast pocket. Unfortunately, even after a successful capsulectomy, there is always the possibility of recurrent hardening.
How long before I can get back to normal?
Although you can gently walk about and do very light
duties from the next day, please avoid any stretching or lifting
during the first 7 to 10 days. Depending on your job many ladies go
back to work after this time. Obviously if this involves excessive
stretching and lifting you are then advised to refrain for a further
10 days. You can usually commence light lower limb exercise after
three weeks. Upper arm exercises and swimming can begin after six
weeks. When exercising always try and wear a good sports bra.
Driving is allowed after 1 week. Sexual activity can be commenced at
around 4 weeks although at this stage only very gentle handling of
the breasts is advised. More vigorous handling can be commenced only
after 2 months!
Breast Augmentation Summary?
The
chances are excellent that you'll be happy with your surgery. Most
patients understand the advantages and benefits of this type of
surgery, and in Dr. Klapper's experience this operation has both
high patient and surgeon satisfaction.
