Breast Implants Guide
The most important decision to make for a patient considering breast augmentation is who is performing the surgery. Choosing a board certified plastic surgeon with vast experience in breast augmentation surgery is a must. Dr. Yates is a board certified Utah plastic surgeon who specializes in breast augmentation and has performed well over 2,000 of these surgeries. In choosing a breast implant, the important decisions that must be made to help achieve the desired breast augmentation result are 1) implant size and dimension, 2) implant type (saline vs. silicone), 3) below or above muscle, 4) breast implant shape, 5) incision choice. Of these, the MOST important considerations are desired breast shape and size. How large do you want your breasts to look? Do you care if your breast size matches your frame or is bigger better? Are you interested in a more natural breast augmentation result or more of an augmented, very round, breast.
Other than choosing the best plastic surgeon for you, the breast implant size is probably the second most important and difficult decision to make. Dr. Yates will help you pick the ideal breast implant size based on breast dimensions, skin envelope and desired shape. This is the starting point for sizing. You will then “try on” external implants of various sizes based on ideal fill and desired goals to help you and Dr. Yates fine tune your goals. Looking at a simulated result with 3D breast imaging helps with this communication. Looking at photos on this site, RealSelf and others can help get an idea of implant size. We want you thinking in terms of cc’s rather than cup size. Cup size is quite variable depending on the width of the chest and bra manufacturer. As a general guide, for a narrow patient an increase in one cup size is in the 125-150 cc range where an average patient is in the 125-175 cc range and a wide patient in the 200-250 cc range. Our opinion is that you should choose implant size based on dimension and the look that you want and fit to the appropriate bra thereafter (and not worry about the letter).
The perfect breast shape for natural breasts should have a little more breast volume below the nipple than above with nipples tilted slightly upward. Often patients who want breast implants like a greater degree of upper fullness than natural. What you consider your ideal breast shape requires careful consideration and discussion with Utah plastic surgeon, Dr. Yates. We have provided a lot of useful information on breast shape here. Choosing the proper implant type, size, and position to match your shape goals is very important. In general tear drop (anatomical or gummy bear) breast implants can help many patients achieve a more natural shape with a smoother upper breast shape while round implants give more rounded cleavage.
“What will I look like after breast augmentation”. Dr. Yates is one of the few Utah plastic surgeons with Vectra 3D breast augmentation imaging. A 3D image is taken and a simulated image can be created with a variety of implant sizes. This is excellent in determining degrees of asymmetry. A patient can “see” their shape and size before surgery.
Generally, if women are unhappy with their choice of breast implant size, they wish they had gone larger. However, there are definitely disadvantages to going too large, with higher complication rates associated with larger implants. Larger implants certainly look and feel less natural as well. This is what makes this decision so difficult.
1) Round silicone breast implant
Advantages : Silicone breast implants are more natural feeling than saline implants. Silicone implants have a lower risk of breast implant visibility and rippling. Silicone implants can have a more natural shape, particularly for very small breasted women. Ruptures are less common. Generally silicone breast implants have a higher patient satisfaction. Most of our Utah patients are choosing silicone over saline.
Disadvantages: Silicone breast implants are more expensive than saline. Because they come pre-filled the incision and scar are longer. There is less adjustability with silicone implants if the breast size is different. Although ruptures are less common, if a silicone breast implant fails this can result in a “silent” rupture that could rarely lead to breast hardening or deformity which can be difficult to improve surgically.
2) Tear drop shaped breast implant (anatomical or gummy bear)
Since their FDA approval for use in the U.S. these have become increasingly popular. These implants have the ability to give a more natural shape even with larger sizes and have lower rates of capsular contracture than traditional silicone implants. The scar is a little larger with these implants (2″), they are a little more expensive and firmer. The risk of rotation is real and higher than we initially thought based on early studies. These implants do very well in the subglandular pocket for many patients.
3) Saline breast implant
Advantages: Saline breast implants are less expensive. There scar can be smaller and there is more adjustability of breast size with saline implants. If there is a failure, a saline implant simply deflates and it is relatively simple to have a new implant replaced.
Disadvantages: Saline breast implants are a little less natural feeling and more prone to rippling. For smaller breasted women the shape with saline implants can look rounder and generally more “augmented”. There is a new saline implant, the ideal implant that has many of the advantages of silicone in regards to feel and rippling but is saline filled.
For nearly all round breast implants Dr. Yates believes that implant placement below the muscle gives a more natural result. In reality, this is a “dual plane” approach with a portion of the implant covered by implant and a portion that is not.
Long term benefits of breast implants beneath the muscle include; improved shape, less implant edge visibility, less theoretical interference with mammography and decreased risk of capsular contracture.
This patient presented to Dr. Yates with a subglandular breast implant and capsular contracture. Revision required breast implant and capsule removal and implant pocket change to below the muscle for an improved shape and decreased risk of recurrence of capsular contracture.
The biggest problem with submuscular placement is that the implants can move significantly with pectoral muscle motion. Depending on the shape and strength of the muscles this can be embarrassing or push the implants to the sides. To minimize these issues a subglandular position can be chosen. Dr. Yates prefers a gummy bear, tear drop shaped implant for subglandular augmentation. These implants have a lower risk of implant edge visibility, rippling and contracture minimizing the complications more commonly seen in subglandualar augmentation. Additionally, gummy bear implants placed above the muscle can feel more “breast like” as the implant is not separated from the breast tissue by the muscle. Subglandular implants requires a patient with good natural support and adequate coverage and Dr. Yates considers only around 20% of patents good candidates for this approach.
The dual plane technique of breast augmentation is a technique where the implant is placed in a partial submuscular pocket and partial subglandular pocket to maximize some of the advantages of placement below and above the muscle. In simple terms the lower pectoral muscle is released from both the chest wall below and the breast tissue above. The muscle lifts above the lower part of the implant which helps to elevate a slightly droopy breast. The upper muscle coverage helps reduce risks of contracture and improve implant coverage.
Dr. Yates uses a simple dual plane technique for most breast augmentation surgeries and a more aggressive version in specific cases to help release a tight lower pole or improve mild droop. A dual plane technique is not a substitute for a lift for a patient with significant droop.
For years supporting the breast tissue over the implants in a lifted position with sutures has been theorized and tried. In practice, there have been no studies showing success but many studies showing failure of these approaches. In general, an implant alone does an “internal lift” to the breast. This effect can be enhanced with modern dual plane approaches. However, if a patient needs a lift beyond what an implant and dual plane approaches can improve, internally supporting with sutures is never enough and a formal breast lift is necessary.
1) Transumbilical breast augmentation (TUBA) – The incision is placed around the belly button. The breast implant pocket is developed through this incision through a small tunnel in the abdomen. Dr. Yates feels strongly that this is a very inaccurate method for breast augmentation. Only saline implants can be used. Any revisions (which are unfortunately all too common with this incision) need to be done with a large incision on the breast. This incision is marketed as “scarless breast augmentation”. It is a good marketing tool…who wouldn’t want breast augmentation without scars? The problem is that the risk of implant rupture is higher, and the risk of implant malposition is extremely high. Most plastic surgeons would never consider this incision and it is a passing fad.
2) Axillary (armpit) incision – The advantage is a scar off the breast. Dr. Yates does not generally prefer this incision as there is no way to feel (with fingertips) inside the implant pockets simultaneously to be sure they are exactly the same. This makes this incision choice less accurate with a higher revision rate. Any revision requires an additional larger scar on the breast.
3) Periareolar (around the nipple) – If this scar heals well it can be nearly invisible – hidden in the color contrast between the skin and areola. Concerns with this incision include slightly increased risk of loss of nipple sensation, possible interference with breast feeding and a risk of infection and capsular contracture from bacteria in the milk ducts. This is losing popularity and many plastic surgeons no longer offer this incision due to these risks.
4) Inframmamary (below the breast within the crease) – The most popular choice for breast enhancement in our practice and among most plastic surgeons. Generally this scar hides very well in the crease beneath the breast. The scar can be very short for saline implants (1-1.5″) and can be relatively short (1.5-2″) even for silicone implants. For anatomical implants the scar is slightly longer than 2″.
*Dr. Yates prefers inframammary for its advantages the majority of the time. At the time of your consultation, Dr. Yates will help you decide which may be best for you.
The two basic breast implant shape choices are round and teardrop (anatomical). Teardrop shaped implants have recently been approved for use in the U.S. Round implants are more commonly used than teardrop shaped implants in the U.S. but with time and experience shaped implants have gained popularity. The main advantage of a teardrop shaped implant is that a more natural shape may be achieved although this is controversial. Additionally, because these breast implants are more cohesive (more solid than liquid) there may be a lower risk of capsular contracture. However, the trade-off is less upper pole fullness, longer scar, firmer result and more expense. Recent studies have shown less difference in outcomes between round and shaped implants than expected and higher risks of rotation than previously considered. For these reasons, Dr. Yates currently prefers tear drop implants only in patients whose goals cannot be achieved with round implants.
To decrease the risk of contracture, textured implants were developed in the 1970’s. Textured implants fell out of favor when silicone implants were taken off the market. A textured saline implant has a fairly high rate of rippling and palpability. With an increasing percentage of silicone breast implant usage textured implants have made a comeback.
A textured implant can help in certain situations where a smooth implant is more likely to shift in position such as poor elasticity or chest wall deformity. These may be more likely to stay put over time with a lower risk of displacement or bottoming out. However, textured implants can have a higher risk of rippling and palpability in patients without much coverage.
A recently discovered illness associated with breast implants is ALCL, a rare type of lymphoma. This is found most commonly (or possibly exclusively) with textured implants. Although ALCL is very rare and typically treatable, Dr. Yates is very conservative with safety related issues and now uses fewer textured implants than he once did. We still use them but only for specific indications.
Silicone is a material that can be made more liquid or solid depending on the degree of cross-linking of the molecules, the thicker the material the more cohesive the implant. Implants with greater cohesiveness may have improved safety and keeps the silicone in place even in the face of rupture. Cohesive implants are a little firmer and can give a rounder breast shape. Each implant brand has a different cohesiveness of their standard round implants, and their tear drop shaped implants. The term gummy bear should be reserved for a highly cohesive silicone implant, although this is not always the case from office to office. Currently the highly cohesive implants available in the U.S are Mentor memoryshape (tear drop), Allergan style 410 (tear drop), Inspira cohesive 3 (round), Sientra shaped (tear drop) , and Sientra style 107 (round). The intermediate cohesive implants are Inspira Cohesive 2 (round) and Sientra style 106 (round).
Although Dr. Yates appreciates the value of a highly cohesive implant in some patients for rippling treatment or prevention, there may not be enough benefit to warrant the excess cost and firmness for the average patient.
Many patients state they desire a certain breast implant profile, for example high profile implants. The profile is the projection of the implant in relation to the diameter of the implant. A high profile implant has a smaller diameter and greater projection (away from the chest) at a certain volume whereas a moderate profile has larger diameter and less projection at the same volume. In reality, the best way to choose the profile is to match the correct diameter to the dimensions of the patient and choose which profile is best based on the volume of implant. For example a thin patient who desires large implants is going to need a high profile breast implant. Moderate and moderate plus profile implants give a more natural result than high profile.
The Ultrahigh profile implant should generally be reserved for patients who want a very large implant for their frame. These have a higher risk of displacement over time and can look narrow, over projecting and “spaced” if chosen for the wrong patient.
There are four FDA approved implant manufacturers in the U.S., Mentor, Allergan , Sientra and Ideal. There are subtle advantages and disadvantages of all three brands. Some plastic surgeons are loyal to one implant brand for ease of use and familiarity. A comparison of some of the pros and cons of the different implant manufacturers can be found here
