When getting breast implants, what gives a more natural appearance, going under or over the muscle?
Which Breast Implant Placement Gives a More Natural Appearance?

Implants placed beneath the breast tissue only tend to give the most NATURAL results!
Most women I see in consultation are looking for a NATURAL, not a "done" or fake result of breast augmentation. I see both professional women who work full-time and full-time Moms, from all over Northern California and also occasionally Canada (my original home!).
Most are very physically fit, at their ideal weight, and are quite physically active, using the pectoralis major muscles all the time for activities of daily living. In fact, we ALL use these muscles routinely.
I believe that NO operation should distort this major muscle of the body and stretch it out over a breast implant. The potential purported benefits do not outweigh the potential negative consequences, in my mind.
Breast implants placed behind the breast tissue only ("subglandular") gives the most natural appearance to the breast, even in very thin women. A subglandular placement avoids the "motion deformity" seen when implants are placed below the muscle ("submuscular" or "subpectoral"), even in women who think they are not that physically active.
Submuscular implants sit high and wide on the chest, and have a slightly less natural appearance in many women. This can be demonstrated by pressing the palms of the hands together in front of the body and flexing the pec muscles in front of a mirror.
Implants behind the breast tissue only also age better than submuscular implants, which tend to keep the implants in a high and wide position as the body ages. Consequently, the breast tissue "falls off" the implant with time, creating a "snoopy deformity" or a "double bubble" appearance.
I like my patients to follow up with me every year, forever! This enables me to ensure they are still looking good and feeling good even years after their breast augmentation.
There are many different surgical techniques in breast augmentation. I strive to educate my patients about how I choose to do things and why, with numerous before and after photos that are shared in the office on the initial consultation.
I always try to do "what makes sense" in Plastic Surgery, and select techniques that I would have done to MY own body!

Your body is the key
In my San Francisco practice most of my patients have implants placed under the muscle. Creating a natural looking augmentation has many factors, all of which need to be addressed.
Some of these include (in order of typical importance):
Implant shape (high profile, moderate profile, low profile)
Implant position (over, under the muscle)
Your plastic surgeon should assess many factors including:
your desired outcome and size
chest wall asymmetries
All of these (and more!) must be considered in creating a natural looking breast augmentation that will meet your expectations.
I hope this helps!

Silicone implants under muscle give more of a natural look
This has been interesting reading for me as I am a plastic surgeon who specializes in BA. I perform about 450 such procedures annually. Let me tell you what I have learned. The best way to choose your implant is to forget about cc’s. Let the surgeon do that…it’s his job. What you should do is be able to communicate the look you are trying to achieve and often pictures of other people is a good place to start. There have been many times when a patient has told me they wanted to be a full c and then I see pictures depicting a d cup. It’s not exact but a good place to start. Take a look at the surgeon’s before and after pictures to se if there are sizes which you find appealing. The measurements which we take are guidelines for some of the decisions which we make. They are not exact criteria for the size you should get and neither are the implant dimensions. There are certainly people who have chosen implants smaller than what their chest could accommodate and the corollary has occurred very often, as well. DO NOT LET YOUR SURGEON PICK YOUR DESIRED SIZE. We are not the ones living with it. Unless there is a definite anatomic restriction it may be the time to get another opinion.
Now a few words about implants. Saline are still the most common in the U.S. but are they the best choice? Not in my humble opinion. I believe them to have too much rippling upon palpation. The only positive aspect is that they require a much smaller incision for placement. As for silicone, I find them to feel the most natural. Silicone implants are much different than the ones which were taken off the market in the early 90′s. The shells are much thicker and the silicone gel is much thicker (cohesive). Cohesive is a term for all silicone and is confusing because there are varying degrees of cohesiveness. The old implants were cohesive but in such a state that they would leak. The new implants (cohesive I) will not leak but if cut in half and squeezed it will not return to the original shape. Cohesive II (Mentor Lumera) are much thicker such that they have a jello appearance when cut and will return to their original form after being squeezed. These are available only in textured and tear drop shape. They offer a bit less rippling than the cohesive I but are also a bit firmer and I believe less of an option for purely cosmetic reasons. The last is cohesive III (gummie bear) which are the thickest. I have not had as much experience with these but am a little discouraged by the feel (too firm) and the incision required (long and inframmamary position). The cohesive II and III are much less pliable and require a larger incision as they are not pliable and have memory of form. My last point…there is never a reason to put an implant above the muscle (subglandular) position. It is a setup for problems. It appalls me that some surgeons still do it that way.

The natural looking breast implant
I strongly concur with Dr. Williams excellent and detailed response.
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. 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.
Under the muscle almost always better
I am a big proponent of submuscular breast implants. They are less like to stretch out the breast and make it droop over time. They hide the implant and make it look more natural. They are less likely to interfere with breast exam and mammography, and they are less likely to get hard. Some surgeons recommend on top of the muscle implants for droopy breasts. It is true they will fill out a droopy breast better at first. However, shortly thereafter, they will drag the breast down and it will be more droopy than ever. Usually, an implant under the muscle is better.
In general, under the muscle gives a more natural result
We women are incredibly aware of our breast appearance-- maybe even more than men are. Breasts are sexual and sensual, a big part of what makes us women, and they can dictate our sense of attractiveness and desirability (for better or worse). Breast augmentation is one of the top three most popular plastic surgery procedures performed. So many women embrace this procedure because it carries little risk of complication. And because an implant can be inserted through a tiny incision in the navel or armpit (and moved into place under the skin), or under the areola or breast, it's a quick, nearly scarless operation.
A major factor that effects how breast implants look and feel is whether they're inserted over or under the chest (pectoral) muscle. Traditionally I do a submammary implant, inserting the implants under the breast tissue and over the muscle because it's technically a lot easier (displacing the chest muscle requires a little more delicacy). It's also quicker: I insert the implant through an incision in the navel, nipple, breast fold, or armpit, place it over the muscle, and then inflate it when it's snugly in place. The result is fabulous: perkiness with barely a trace of scar.
If you want the most natural-looking breast you'll need a subpectoral implant, in which the implant is placed under the muscle. This procedure also requires the merest incision- about three centimeters in the crease under the breast or at the edge of the nipple-- and diminishes the incidence of capsular contracture, the formation of hard scar tissue around the implant which occurs in 10 to 30 percent of cases.
Subpectoral implants aren't right for everyone, though. If you have saggy breasts, and implant placed under the muscle won't fill out that empty breast sack, and you'll get what we call the "double bubble" look, where the implant is situated next to your armpit and the breast hangs several inches below it. Instead, you can have a procedure called augmentation mastoplexy, in which the implant is placed under the muscle and the skin on the breast is lifted and tightened.
In short, you must know--realistically-- what you are starting with, as well as what you want to look like when surgery is done. Do you care more about the placement of the scar or about a quick painless procedure? Do you want a natural appearance or a round, perky look? These are some of the factors I weigh with my patients when evaluating what type of procedure to do.
Under the muscle is more natural, but size is a more important factor
The pec muscle looks like a triangle with borders along the sternum and clavicle. When an implant is under the muscle, the muscle helps maintain the slope to the upper portion of the breast. Natural breasts have more of a slope above, and curvature below the nipple. That being said, if you choose large implants (or too large), no matter where you place them, they will look fake. Reasonable sized implants can be make to look natural, and the muscle helps.
Which Position Gives The More Natural Looking Breasts - Under Or Over The Pectoralis Muscle?
The placement of subpectoral implants is done after the pectoralis muscle is cut off its insertion into the fifth rib. Once this connection of the pectoralis muscle is released, the muscle retracts upward, making a sub-muscular implant actually a partially sub-muscular implant. When the muscle is released upwards even more, it is referred to as a Dual Plane.
There was a famous plastic surgery meeting in Dallas where a Board Certified plastic surgeon showed a number of round implants in the partially subpectoral space on lateral mammogram, and they were all teardrop due to the muscle pushing on the upper 50-70% of the implant, and the lower portion bulging forward. Round implants in the partially subpectoral space give the natural teardrop appearance of mature breasts, but have the advantage over teardrop implants, that no matter how they turn, one will never get a diagonal breast.
Therefore, round implants in the partially subpectoral space give the most natural appearance to the breast.

Breast Implant Placement for Natural Appearance
Most physicians agree that placing the implant under the muscle offers the most natural appearance. Of course other factors such as type of implant and shape of implant can also contribute to a “natural” appearance. Silicone implants have a tendency to look more natural, as do tear drop or biodimensional implants. If you are concerned about ensuring a more natural appearance after your augmentation surgery, be sure to discuss this with your doctor during your initial consultation so he or she can help you select the implants that are best suited to achieve your goals.
