Under Vs over the Muscle for More Natural Results?

I'm currently a big 'A', small 'B' cup, my height is 5'5.5", slim body frame and weigh about 119lbs. I'm 30 and have 2 children who were both breast fed. I would like to be a full 'C' cup, I've recently been to see a consultant who has suggested he will insert 260cc textured Silicone breast implants (High profile) over the muscle. Does this seem ok?

Why subpectoral (under the pec muscle) implants

+3

Your instincts are correct. Breast implants today should be under the pectoralis muscle for a number of reasons but one of them is to pad, protect, and blend in the implant so it looks like a natural breast and not an implant under a breast. This is not just a choice thing that's up to the whim of the patient or the surgeon. It's based on decades of experience with breast implants.

In my opinion, a surgeon who is still putting breast implants above the muscle, doesn't know how to position implants properly under the muscle. Implants have to be sized, positioned, and filled (if saline) properly. The objections expressed by the surgeon you mentioned are not true for a properly done procedure. There should be no long term consequences to the pec muscle, and the only trade-off for this is increased movement of the breast when the pec muscle is flexed. This is an issue for only a small number of show body builder women.

It is possible to get an initial satisfactory result with a gel-filled implant placed above the pec muscle but it is likely to eventually be noticeable and all the long term advantages have come down on the side of sub-pectoral placement.

I would add that there is no apparent advantage to a textured surface implant except to try to lock it in place if it's not round. Most situations do not need an implant that is not round. There appear to be several disadvantages to the textured surfacing over the long run.

Breast augmentation under versus over the muscle

+3

In general, most of us would agree that under the muscle is preferred in most cases, but you should know that for the right patient with the right anatomy, you can get a nice result with the implant placed above the muscle as well-- it really just depends on the surgeon's judgement, style and experience, and combining that with what your goals are.

I would speak to at least one or two more plastic surgeons in your area and go with the one you feel the most comfortable with-- this will give you the best chance at a nice result.

Good luck!

Unless you are an extreme athlete put your implants under the muscle!

+3

Dear Dufu,

It is generally agreed that the best long-term results occur with under the muscle placement of breast implants. The implants are better protected, rates of capsular contracture are typically lower, and if you have saline implants or are very thin, rippling/waviness of the implant is less detectable. I typically only put implants over the muscle if patient use silicone implants and are extreme athletes (eg. body builders, martial artists, heavy weight lifters, etc.) The reason for this is that the pectoralis muscles in these women are so strong that they push the implants down and out from the center creating a large gap and breasts that are too low. Also, if they are in competition gear every time their muscles flex, the implants move unnaturally. The average woman does not have this concern or goes to the gym and works out like most of us (not super aggressively.) You seem really tiny, so I would recommend that under the muscle placement be entertained.

Good luck,

I'm not sure I agree with what you've been told but there are many different opinions in the operation that you're seeking.

I don't think you'll be a full C cup in 260cc implants, even subglandular. Committing to a cup size can be disappointing. The size may be smaller than you are expecting -- it's not easy to know what you think a full C cup is. I do however think that the size you've been suggested will look great on your body. It is a very tasteful size selection and your ABPS Board Certified plastic surgeon see's that. You should try on that size implant in a bra with a fitted shirt over it (your consultation may have provided that experience). It will appear similar to the end result in clothing.

The muscle wastes some inferiorly when it covers the implant, but it doesn't die. The fact is that you're pretty thin, so unless you're very muscular it is already a thin muscle and it won't make too much of a difference in soft tissue coverage but above the muscle your risk of capsular contracture is higher. What you are reading is correct, submuscular placement is the most popular placement of an implant due to the best longevity demonstrated on countless clinical studies. The subglandular position was the original placement of implants but after enough experience this positioning was only used under certain circumstances (adequate breast tissue coverage, body builders). Most agree that submuscularly, implants age better.

Breast Implants Position

+1

The term 'sub-pectoral' or 'sub-muscular' is somewhat misleading, as implants placed under the pec major are only partially covered by the muscle. The pec major covers the upper/medial half of the breast area, so a 'sub-pectoral' implant is truly subpectoral only in the upper and medial aspect of the augmented breast, while the lower and lateral aspect of the implant is actually in a sub-mammary position. Because sub-pectoral implants are, in reality, both sub-pectoral (upper/medial breast) and sub-mammary (lower/lateral breast), this placement has more recently been referred to as a 'dual plane' approach to breast augmentation.

There is also 'total submuscular' implant placement, in which the implant is positioned behind the pec major and the serratus anterior muscle, so that the entire implant surface is covered by muscle tissue. This is not commonly done for cosmetic breast augmentations, but has been used for breast reconstruction using breast implants.

There are a number of compelling reasons for selecting subpectoral placement over submammary placement. The most significant is that fact that radiologists have indicated that it is easier to image breast tissue by means of mammography when the implant is subpectoral. The pec major also provides an additional layer of tissue to conceal breast implants in the 'social aspect' of the breasts - that part that is easily visible in swimsuits and lower-cut clothing. Additionally, the pec major is quite effective at flattening the upper pole of a breast implant so that a natural slope for the upper aspect of the breast is created.

Implants placed on top of the pec major tend to look very convex in the upper pole. The breast begins quite 'abruptly' in the upper aspect of the chest, and the appearance is therefore distinctly unnatural. Submammary implants are also more likely to have visible implant folds and ripples in the cleavage area. Another consideration is the fact that there is some evidence which suggests that the risk of capsular contracture may be lower with subpectoral implant placement. Even if the risk of contracture is the same, a mild contracture tends to be less noticeable and therefore less of a problem for the patient when the implants are in a subpectoral position.

Submammary placement may produce a reasonable result for fuller figured patients with larger starting breast volumes, as the larger amount of natural subcutaneous fat and breast tissue helps to conceal the implant contours. The problem is that as breasts age, they tend to deflate - especially in the upper pole. So what was adequate implant coverage in the cleavage area at age 27 may be inadequate coverage at age 37, and implant folds and ripples gradually become visible. So subpectoral placement is the best choice for both the short and long term.

'Sub-fascial' breast augmentation is also possible. Fascia is the term for a sheet of connective tissue made of collagen, and the pec major has a fascial covering as most muscles do. Breast implants can be placed behind the pec major fascia only, rather than behind the entire muscle, however this approach is not widely used. The pec major fascia is a relatively thin layer of tissue, so it is not nearly as effective in concealing breast implants as the actual muscle itself. Partial sub-fascial placement can be useful in some breast augmentation revision surgeries, where variations in pec major origin or incorrect release of the pec major has resulted in significant distortion of breast appearance when the muscle contracts.

Breast implants should be placed under the muscle

+1

Most surgeons would advise against placing breast implants above the muscle. The opposite is true; most surgeons place breast implants beneath the muscle. This is performed for three basic reasons:

1. By placing the implant beneath the muscle, the muscle camouflages the implant to some extent so your breast looks more natural and less circular.

2. The second reason is that it is easier for a radiologist to read a mammogram when it is below the muscle.

3. The third reason is that it reduces the complication rate for capsular contracture.

With respect to your consultation, I would suggest a second opinion. Namely because most surgeons no longer use textured implants routinely. Textured implants were at one time thought to reduce capsular contracture complications. This is generally felt no longer to be true.

All implants need coverage, only some need muscle coverage

+1

I perform both subglandular and submuscular breast augmentation and can get very nice, natural results with both approaches. As you can see from the other answers there are a lot of variables that are taken into consideration when performing breast augmentation. For a lot of reasons including appearance, tissue coverage of a breast implant is important. If you have enough native breast tissue, this may be enough to cover the implant. If not, the muscle will add a layer of coverage. From your description of being a "big A," I would bet that you would better off with an implant under the muscle and would suggest that you seek another opinion.

Breast implants placed under the muscle will look and feel more natural

+1

Unless you have a sagging breast, the submuscular approach will fell more natural if the operation is a success.

The high profile implants look less natural than low or moderate profile plus implants.

Seek a second opinion.

Most implants go under the muscle today

+1

Over the years implants have been placed above and under the muscle among other combinations of the two. Currently the dual plane technique is the most commonly uses - this where you place the implant below the muscle but the lower portion of the muscle is released surgically to give a more natural appearance. There are only a limited number of indications for going above the muscle. The muscle will not "die" as suggested by the consultant you saw. A natural appearance also comes from your own body type and implant size. The thinner you are the more natural an implant will appear under the muscle. Discuss your concerns with a board certified plastic surgeon.

Over or Under Muscle

+1

I definately think that you would happier with implants placed under the muscle from your description of your body size. I, like most other plastic surgeons of my generation, placed most implants over the muscle in the mid80s to mid90s. Since then almost all of my patients have had their implants placed under the muscle. There definately is a more natural appearance, but there is a bit more pain and discomfort early on.
