Which Breast Implants Result in Natural Slope and Cleavage?

My wife is going to get Breast Augmentation in 3 months. She's 130 lbs, 5'4", 34A (breast fed 2 children), breast width was narrow, long torso and curvy hips, measured 1" on the upper pec/armpit area. We have decided on Silicone Breast Implants and under the muscle. She wants to be a small/medium C. One doctor said 350cc smooth high profile round implants. Our fear is we don't like the grapefruit look under the skin. We want a natural slope and decent cleavage. What are your thoughts? Which implant (high profile, mod+, mod) and what size would you recommend? Attached picture with measurements.

Natural looking breast augmentation

A natural-appearing breast is noticeably fuller in the lower pole (below the nipple) than the upper pole. In profile (viewing from the side), the upper pole slopes gradually from where the breast begins in the upper chest down to the nipple, and the lower pole is full and rounded. For any patient considering breast augmentation, there is an implant size above which the upper pole begins to look rounded, convex, and unnaturally full. Mild to moderate upper pole fullness can look beautiful and youthful, but excessive upper pole fullness due to overly-large implants looks decidedly fake, and like what most people think of as a 'boob job'.
The actual size of a breast implant, measured in cc's, is really not very descriptive of what a breast augmentation will look like, or what the cup size will be. It is all relative to the size of the breast and the size of the patient preoperatively. A tall, broad-shouldered patient with small A-cup breasts may require 450cc implants to achieve a C-cup breast volume postoperatively, while a shorter patient with medium B-cup breasts may only need a 250cc implant to achieve a C-cup breast volume.

Choosing the right implant look

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

Based on your wife's photo, bra size, weight and height a 350-400cc moderate plus silicone implant would be my highest suggestion. Reason is, a high profile implant is selected more for petite women with a 30-32 bra size. High profile implants have a small base & project forward, giving the more "done" vs "real" look. Moderate profile implants have a wider base and much lees of a projection meant for a 34+ bra size. Moderate plus is basically in the middle, for a 32-34 bra size, projection is more realistic but still with some perk.

Thanks for all the info.  I prefer High profile implants for most patients that want to be a little bigger but are fairly narrow. Moderate plus are all right as well, they can give a bit more cleavage with less projection at the same volume of the HP's.

The natural looking breast implant.

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

I offer patient's a simple analogy to illustrate what we mean:

Q: If you take a baseball and you cover it with a silksheet, what will it look like?

A: Like a baseball, you will even see the stitching.

Q: Now if you take that same baseball and cover it with a comforter what will you see?

A: It depends on how thick the comforter is but generally you will see a softly shaped lump.

So now the question is what do you have on your chest, silk sheets or comforters?

The way we determine this is by looking at your chest, if I can see your ribs (under the muscle) then you anatomy will have a hard time disguising the implant whether it is placed under or over the muscle and you are more likely better off with a silicone implant. Another way of measuring this is to pinch your upper chest skin (similar to pinch and inch of your waist on the Special K commercial). If you have less than an 2 cm (under 4/5 of an inch) than you have "silk sheets"

If you have a thicker skin/fat/breast layer that pinches over an inch than you have the option of going under or over.

Now the exception to the rule:

Q: What happens if you change the baseball to a volleyball?

A: All bets are off, whether you put it under or over the muscle it will not look natural.

The last issue is the implant shape. A moderate or moderate plus implant that has minimal projection is more likely to be more natural appearing (less baseball like). However many paitents seek upper pole fullness and larger volumes with a small BWD and the only way to achieve this is with a high profile implant.  There are some anatomic shaped implants but I have generally found them to produce no significant difference in outcome with the exception of breast cancer reconstruction. However, this is my personal opinion

Best breast implants for natural shape

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

There are several factors to consider. In general, silicone will feel and behave more like a natural breast. Then next step is to select the size, and the most common way to do this is trying on samples in a bra with the desired cup. Once the implant size is decided, then the implant with the best match of diameter to the base diameter of the breast is determined. That is how the cleavage will be optimized. In general, a high profile implant is to maximize volume on a narrow base, low profile to minimize size on a wide base. High profile implants have a steeper angle from the upper chest into the breast so they tend to have less of a slope.

In my experience, under the muscle silicone breast implants give the most natural result. The extra tissue coverage from the muscle helps camouflage the implant look. Additionally, there is no question that the silicone implants feel much more natural than saline implants. Good luck with your surgery.

Breast Implant Size

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
Breast Implant Size is a combination of subjective and objective criteria.380 cc is a reasonable recommendation. There is not a direct correlation between the cc's of a breast implant and the corresponding cup size, as cup size is an inexact measurement that varies considerably among companies and even within the same company. Online consultants will not be able to guide you as well as surgeons who perform in person consultation.

The size of the implants are based on a combination of a patient's goals and objectives and her anatomy. In order to provide a natural looking augmentation, the surgeon needs to evaluate many factors including soft tissue coverage, skin laxity, chest wall width, breast imprint width, the shape of the breasts and relative level of constriction to ensure that the breast implants are appropriate for your body.

Which Breast Implants Result in Natural Slope and Cleavage?

The current trend in breast augmentation is for a more natural result. There are several new additions to the breast implant family that makes this much easier for your plastic surgeon to help you achieve this goal.

One the use of silicone implants has made a dramatic change in terms of natural feel and shape. The silicone implants over saline implants are much softer and look much more natural. With a silicone implant a patient would have to place a much bigger implant to have a very round “fake” appearance. This is because the saline implants are very firm and thus create this round unnatural shape. The silicone implants because of how soft they are tend to give subtle and natural appearance.

The other new addition is the use of shaped implants. Shaped implants are great for patients that a very afraid of looking overly round and fake. The shaped implants are made with a natural slope to them, this way patients can have more natural shape with their augmentation. The shaped implants have been great for my breast reconstruction patients and for patients that want a larger implant, but still want to look natural. In smaller implants the difference between the silicone shaped and the silicone round implants is very little.

Please discuss your breast augmentation surgery with your board certified plastic surgeon and let them help guide you during the process.

Simply put: Pick the best plastic surgeon that you trust, be clear about your desired outcome and let him/her select the best implant. It is very difficult to determine the exact size and shape implant you will require to best match your ideal breast image without an examination by a board certified plastic surgeon. Not just any board certified plastic surgeon, but one with many years of frequently performing breast augmentation surgery including different approaches, techniques and implant choices. This is because several measurements not to mention your breast characteristics are needed to determine the optimal implant size to obtain your goals. Without knowing these dimensions it would be difficult to make this determination. For example, the existing base width of your breast will determine, in many cases, the maximal volume per implant profile that you can accommodate. To illustrate; a 100 cc difference may make a significant difference with a narrow base width breast, but much less of a difference if you have a wide chest wall and wide breast “foot print”. Therefore, just because your friend may have a great result with let’s say a 350 cc implant to make her go from a “A” cup to a “C” cup size does not mean that you will have the same result with the same size implant. . Further simply placing implants in a bra to determine the size best for you is not always accurate as the bra often distorts the size, is dependent on the pressure the bra places plus the implant is outside your breast and not under it among other variables. Computer software morphing programs that automatically determine the best implant size can be helpful in some but not all cases (e.g. doesn’t work well in my experience with existing implants, sagging or asymmetric breasts). Using “want to be” photos however are useful if simply provided to the surgeon as I will further explain in the link below.

Volume, dimensions, projection, and width

Once you have selected a volume based on the visual you get from trying on sizers, the surgeon can use the measurements to determine which implant will give you the look that you desire.  If for instance you are using saline high profile round implants, you can achieve natural if you are at the low end of the volume range of a larger implant, if you choose a smaller implant and fill it to the middle of the range to get to the same volume you will get more cleavage and an intermediate look, if you choose the smallest implant that can be used to get to the same volume, and fill it all the way up, it will be the most projected of the three looks.  For silicone, you just need to look at the dimensions of the implants and decide with the surgeon which will give you the projection you are looking for.
