Under muscle vs Over muscle
I would say that most plastic surgeons in the United States place breast implants below the muscle or submuscular. I favor this position as well in most cases. The muscle under the breast does not completely cover the implant. It covers the top half or maybe the top third of the breast implant in most cases. Some plastic surgeons refer to this position as partially submuscular, which is more accurate. In some cases, it is referred to as "dual plane" which is another variation. They all serve the purpose of providing additional coverage over the breast implant which is especially important in the upper chest to give a smooth transition in the upper chest/breast area. Also it will prevent visibility of the implant and helps to camouflage rippling and wrinkling of the implant. This is especially important in women with low percentage body fat.
The downside is more discomfort after surgery, which I have not found to be an issue; the possibility of movement of the breast implant with contraction of the muscle which is rarely a complaint unless the movement is significant and the woman is a body builder who competes. Mammography may be facilitated if the implant is under the muscle.
The alternative is over the muscle or subglandular. This may be reasonable in women with more breast tissue and/or greater percentage body fat since they have more tissue for coverage of the implant. Also, some women with a mild degree of droopiness of the breast may benefit from the subglandular position. (In some cases the dual plane technique is used for this purpose as well.)
There can be less discomfort after the subglandular procedure. There is a slightly greater chance of capsular contracture with silicone breast implants over the muscle.
Thank you for this question and I hope you find this information helpful and good luck.
Breast Implants over or under the Muscle?
The positioning of breast implants above or below the pickles muscle is a decision that will likely influence the outcome of surgery from most patients who undergo breast augmentation surgery.
The submuscular positioning allows for more complete coverage of the breast implants leading to generally more natural feel/look of the implants in the long-term. This position will also decrease the potential for rippling and/or palpability of the implants (which may increase with time, weight loss, and/or post-pregnancy changes).
The submuscular positioning also tends to interfere with mammography less so than in the sub glandular position. The incidence of breast implant encapsulation (capsular contraction) is also decreased with implants placed in the sub muscular position.
As you can tell from this description, I prefer the use of the sub muscular ( dual plane) for most breast augmentation patients.
I hope this helps.
Difference between Over and Under the Muscle Breast Augmentation
No breast implants are perfect. A common weakness of ALL breast implants is their forming folds and rippling. To hide these ripples well, the woman's chosen implants are measured to be f a diameter which is covered by her current breast tissue. If this is ignored and an "A to a full D" augmentation is performed, ONLY the top of the impant is covered by breast tissue and te entire periphery and it's ripples are visible and palpable along the entire 360 degrees circumference.
Placing the breast implant under the muscle under the breast maximizes the amount of implant coverage and maximally reduces ripple visibility. In addition, placement under the muscle is associated with a lower ncidence of hard scar formation around (capsular contracture) around the breast implants.

Breast implants over or under the muscle
Thank you for your question. Breast implants under the muscle make it somewhat easier to get mammograms and have a slightly lower incidence of developing a hard scar. The muscle can also pad the implant in thin women to avoid severe rippling. Women who have enough of their own breast tissue may be a candidate for over the muscle because their own tissue will pad and cover the implant making it less noticable. Both techniques are acceptable but selecting the right technique for the right patient is key. Implants under the muscle do bounce and jump with exercise. I hope this helps.
Breast Implants Over or Under the Muscle
Should breast implants go over the muscle or under the muscle - which is better?
An implant placed above the muscle is referred to as 'sub-mammary' (or 'sub-glandular'), while an implant placed under the muscle is referred to as 'sub-pectoral' (or 'sub-muscular'). The muscle in question is the pectoralis major. 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.

What is the Diff Between over the Muscle & Under the Muscle Breast Implants?Answr
I usually tell my patients that under the muscle gives you a more "natural" look and over the muscle gives more of a "wow" look. Under seems to have less hardening issues but it does have the "Animation effect" where the bottom of your breast tightens with pec flexion. Here in the states we do mostly below and in Brazil mostly above. There are some cases that really do need above the muscle but they are not as common.
Placement Of breast Implants Over/Under Muscle
I place almost all breast implants below the chest muscle as do most US plastic surgeons. This provides an extra layer of tissue to help prevent implant visability. There also seems to be a lower rate of capsular contracture when implants are placed below rather than above the muscle.
Why a submuscular breast implant
It seems that the best place for an implant is within the breast itself, subglandular. Most breast implants are placed under the chest muscle (upper portion only) for two reasons. First, capsular contracture is much reduced by submuscular placement. Second, the upper edge is smoothed by the muscle and the implant edge and artifact such as ripple do not show through giving better coverage and a natural look.

Pocket position for implants
Some implants are placed above the muscle and under the gland. This is better in larger breasted women. Under the muscle in the majority are really dual plane meaning that the muscle is divided inferomedially and the implant is placed below the muscle superiorly but is only covered by the gland inferiorly. Uusaly this is better in thinner patients.
