Selecting a Breast Implant Size
During your consultation, Dr. Zemmel will discuss with you your overall size goals for your breast augmentation. Many factors contribute to your overall size and shape. Our plastic surgeon will take a number of measurements of your breasts and then show you a range of sizes that will meet your goals. You will then try on a form-fitting shirt with the implants and examine your new shape. Keep in mind this process is to get you comfortable with your new look and make sure you are satisfied with the size and shape. Dr. Zemmel will encourage you to try on a range of implant sizes, so you may see the differences in size and shape. This will allow you to rule in and rule out certain sizes.
The majority of women (around 80%) seeking breast augmentation desire a C cup as their final size. However, Dr. Zemmel sees patients desiring a wide range of final results. Dr. Zemmel treats patients who have a wide range of body types, shapes, and breast sizes. Dr. Zemmel is comfortable performing conservative as well as a large breast augmentation. Women frequently desire a B cup to a DD as their final size.
Breast implant sizes are not measured in cup size, but rather by volume measured in milliliters (ccs). In fact cup size is a relatively inaccurate measure of breast size as there are a number of different methods of measuring breast and chest circumference. There is no industry standard for fabricating bras therefore each bra is slightly different. If you have an average height and weight and have a beginning breast size of an A or B cup, you will experience a 1 cup size increase for each 200cc of implant volume added. If you have a smaller or larger build, then this number will vary accordingly.
Dr. Zemmel believes that each woman has a range of sizes that will fit comfortably and naturally on her body type. Within that range you can be more conservative or more liberal depending on your preferences. Dr. Zemmel prefers a natural, balanced look for his patients and does not believe in an “over done” or imbalanced look.
Surgical Technique of Breast Implant Placement
Submuscular Versus Subglandular Implant Placement Techniques
Augmentation mammaplasty or breast augmentation is the surgical implantation of prosthetic breast implants for cosmetic or reconstructive purposes. Reasons for breast augmentation include increasing self esteem, improving one’s appearance in clothing, achieving more balance and harmony between the upper and lower body, correction of breast asymmetry, and replacing the breast after removal due to cancer.
Both saline and silicone breast implants are available for implantation. Several different options exist for the type of incision used for entry into the breast. The implants are placed beneath the skin and breast and finally rest either beneath or on top the pectoralis major muscle. There are advantages and disadvantages of each approach.
Placing a breast implant on top of the pectoralis muscle is called the subglandular approach. The advantage of placing the implant in this position is that recovery from surgery is somewhat easier and the lower portion of the breast is made fuller and rounder. The disadvantages include a greater chance of feeling (palpating) the implant more often, increased visibility of the implant, an increased risk of visible rippling, and an increased risk of capsular contracture, or scar tissue forming around the implant.
The submuscular approach achieves implant placement by putting the implant beneath the pectoralis major muscle of the chest. The approach calls for elevation of the pectoralis muscle in surgery and creating a breast pocket directly on the rib cage. While the approach requires slightly more surgery than the older subglandular approach, most modern plastic surgeons place implants in this position because the benefits clearly outweigh the disadvantages. By placing implants submuscular, there is an additional tissue “padding” over the implant. This gives a number of beneficial effects including lessening the palpability of the implant, less risk of capsular contracture, lower risk of implant malposition.
Dual Plane Breast Augmentation
In recent years a newer hybrid approach has been advocated by many board-certified plastic surgeons including Dr. Zemmel. This newer approach places the implant partially beneath the pectoralis major muscle and partially beneath the breast tissue itself. Termed the “dual plane” approach, this procedure combines the advantages of both subglandular and submuscular breast implant placement. The upper one-half to one-third of the implant is covered by muscle, while the lower portion of the implant is beneath the breast tissue itself. This approach can be performed through a periareolar or inframammary incision but not through the transaxillary route.
Dr. Zemmel performs the dual plane approach when possible because of the significant advantages and low risks of this technique. Dr. Zemmel believes the dual plane approach gives a more natural, tear-dropped shape to the breast and reduces the potential long-term complications associated with breast implants. The advantages include:
- Less occurrence of capsular contracture
- Less occurrence of rippling
- Less chance of feeling the breast implant (palpability)
- A more natural, tear dropped shaped look
- A softer, more natural feel to the breast
During your consultation, Dr. Zemmel will interview you to determine your goals for surgery. A full history and physical will be performed to determine which breast implant placement technique is right for you.
Types of Breast Implants
Silicone vs Saline
Breast implants are made from a silicone rubber shell filled with either saline solution or silicone gel. Both implants can give excellent cosmetic result in properly selected patients. There are a number of differences between saline and silicone implants:
- Improved texture and feel with silicone implants. This difference becomes more prevalent the thinner the patient. The more you have to “bury” the implant under, the less the difference between silicone and saline become.
- Lower rupture rate for silicone implants. The current data suggests a 1% rupture rate at 6 years for silicone and 1.8% per year for saline.
- Rupture of a saline implant becomes evident over several days’ time. Typically, when a saline implant ruptures, the implant develops a small fatigue fracture in the shell or the fill valve fails. Saline begins to leak and the implant deflates over one or two days, and the breast becomes smaller. Silicone implants are relatively form stable and do not change shape. There is no leakage of gel from the implant as the gel is “cohesive.” Silicone implants are said to rupture silently. The FDA therefore recommends that women undergo an MRI of the breast 3 years after surgery and every other year thereafter to assess the integrity of a silicone implant. This study may or may not be covered by health insurance so patients should expect this to be an out-of-pocket cost in the future.
- Silicone implants are somewhat more expensive than saline implants.
Selecting a silicone versus a saline implant can be a complex question. The final decision depends on the shape of the breast, the quality of breast tissue, the distribution of breast tissue within the breast, the thickness of the tissues, the shape of the chest wall and rib cage, and most importantly, each woman’s preference. Dr. Zemmel will guide you through each step of the decision-making process. Ultimately, Dr. Zemmel recommends selecting an implant that you have the most confidence in and that gives you the greatest peace of mind.
Gummy Bear Implants
In addition to the traditional silicone implants, Dr. Zemmel offers the Natrelle® 410 shaped textured implant – also known as the “gummy bear” implant. This FDA-approved breast implant offers patients unique benefits as well as a lower rate of post-operative complications. It was created to make up for the shortcomings of previous implant options and has shown to provide enhanced results for the right candidates.
Dr. Zemmel is one of few surgeons in the region who currently offers the Natrelle® 410 for cosmetic breast surgery. He underwent specialty training from Dr. Charles Randquist of Stockholm, Sweden, the plastic surgeon who is known for his advanced surgical expertise in creating beautiful results with the Natrelle® 410 implant. Following this hands-on learning, Dr. Zemmel has proudly offered his breast augmentation patients the additional option of the gummy bear implant, which holds specific advantages over other implants.
The Natrelle® 410 is a highly cohesive (level III cohesivity), completely form-stable implant. This is possible due to the additional cross-linking in the silicone molecules, which causes the implant to have a firmer consistency. Since it is both form-stable and tear-dropped shape, the implant prevents against a loss of upper pole fullness when in a vertical position and lowers the risk of rippling and rupture. Additionally, the textured surface of the gummy bear implant has shown to lower the rate of capsular contracture compared to that of smooth versions.
The implant comes in 12 different models, which includes projections of low, moderate, full, and extra; heights of low, medium, and full; and customizable width and volume. Patients interested in gummy bear implants will be educated on what to expect from Natrelle® 410 to understand if the implants are the best option to help them achieve their desired outcome. If you prove to be a good candidate for the Natrelle® 410 implants, Dr. Zemmel will help you find the best model that can provide you with your goal results.
Saline Filling Recommendations
Saline implants are made from a layered silicone rubber shell filled with sterile intravenous saline solution. Saline implants are manufactured without the saline fill. Dr. Zemmel places the implants deflated within the breast pocket and then inflates them once in the breast pocket. Saline implants have a fill range. This means each implant has a minimum and nominal fill volume. Dr. Zemmel believes filling saline implants to their maximum fill volume and in some cases slightly over-filling the implants gives a more natural result and reduces the risk of visible or palpable implant rippling. Dr. Zemmel also believes that maximum filling of an implant reduces the risk of “fold flaws” or wrinkling of an implant. Long term this is likely to reduce the risk of fatigue fractures forming, therefore reducing the risk of rupture. Dr. Zemmel believes proper filling of a saline implant is critical in obtaining an excellent cosmetic result and increases the longevity of the implant.
Smooth vs Textured
Breast implants are manufactured with two types of surface textures: smooth and textured. Textured implants were designed in response to the relatively high rate of capsular contracture with older generation implants. By creating a textured surface with very fine surface irregularities intentionally built in the surface, the implant designers believed this would redirect or reorient the scar tissue and prevent it from tightly contracting around the implant. While this helped in preventing capsular contracture, a number of other consequences were found to occur. The textured surface acts as “Velcro” between the implant and the bottom surface of the breast tissue. This increased the likelihood of visibility of the implant, rippling, and palpability of the implant beneath the surface of the breast. Dr. Zemmel also believes textured implants have a higher rupture rate than smooth surfaced implants. Most plastic surgeons including Dr. Zemmel believe textured implants have very limited application in modern breast augmentation surgery. The excellent performance profile of smooth round saline and silicone implants allows Dr. Zemmel to offer these implants exclusively to his patients.
Smooth surfaced implants have no texturing. This allows a smooth inference between the implant and the breast tissue capsule. It allows the implant to glide easily and rotate through the breast pocket without the “Velcro” effect of texturing. Dr. Zemmel believes smooth round saline or smooth round silicone implants when placed in properly selected patients give the optimum results immediately and long term.
Moderate vs Moderate Plus vs High Profile Breast Implants
Breast implants are manufactured in a number of shapes and sizes. Allergan has three levels of forward implant projection for any given volume. They are called moderate profile, moderate plus profile, and high profile breast implants.
The profile a breast implant refers to is the amount of projection (forward height) for a given volume and diameter. Moderate profile implants are the flattest, moderate plus profile are medium height, and high profile implants project the farthest for a given fill volume.
During your consultation, Dr. Zemmel will select a range of implants that will fit your breasts and frame. You will try on a number of implants to approximate your final result. Trying on implants is an extremely important part of preparing for your breast augmentation. It allows Dr. Zemmel’s patients to gain a sense of what their final results will look like. Dr. Zemmel’s goal for your surgery is to give the most natural, proportional, and aesthetically pleasing result. Moderate and moderate plus profile implants are typically used in women who are taller with a slightly wider rib cage. For women with a more “petit” chest and smaller breasts who wish to enlarge 2 or 3 cup sizes, Dr. Zemmel often recommends a high profile implant. Oftentimes, both a moderate plus or high profile implant will work very well and the final decision is based on the artistic preferences of both Dr. Zemmel and the individual patient.
You will be given several opportunities to try on implants before surgery. This will allow you to confirm your selection of implant and proceed with surgery with confidence.
Life Span of a Breast Implant and Future Breast Implant Maintenance
Breast implants are not lifetime devices, and you should expect to replace your breast implants at least one in your lifetime. Breast implants are like any other mechanical part of product you may purchase: they have an associated life span. Saline breast implants have a rupture rate of 1.8% per year, while silicone breast implants have a rupture rate of 1% at 6 years. The current available data suggest that silicone implants have a significantly lower rupture rate when compared to saline implants. The average replacement time for all patients undergoing breast augmentation is 15 years. It is important to understand that many women go much longer than 15 years before rupture, while a few women require earlier replacement.
Breast Implant Rupture
Saline Breast Implant Rupture
When a saline breast implant ruptures, it is usually due to a small crack in the outer shell of the implant developing over time. The crack develops from normal wear and tear over many years time. This leads a deflation of the implant, and the ruptured implant will deflate over one to three days. This causes the breast to deflate, and a shape change will occur over a day or two. For most patients it is obvious when a saline deflation occurs.
Silicone Breast Implant Rupture
Newer cohesive silicone gel implants have a different natural history for rupture. The cohesive gel filling does not leak out, and the shape of the implant is relatively form stable. When silicone implants rupture, there is no shape change, no change in sensation, and rupture is virtually asymptomatic. When these silicone implants rupture, they are said to rupture “silently.” Because of this, the FDA recommends that women undergo periodic screening for rupture of their silicone breast implants. The FDA recommends that women who have silicone breast implants undergo a surveillance MRI 3 years after surgery and every 2 years there after in order to detect rupture. This may or may not be covered under your health insurance plan.
When rupture of either a saline or silicone breast implant occurs, Dr. Zemmel recommends replacement of both breast implants.
Breast Implant Warranty
Allergan, the manufacturer of both saline and silicone breast implants, warranties the implants against rupture. If you experience a rupture, Allergan will pay for the replacement for the first 10 years after your original operation, as well as provide financial assistance for the operation. Dr. Zemmel and Allergan will supply you with implants at no charge. Dr. Zemmel will go over the different scenarios in detail during you consultation. Dr. Zemmel, Richmond Aesthetic Surgery, and the breast implant manufacturer Allergan will do everything possible to relieve the financial burden from you during an implant rupture.
