What's Better - over Muscle or Under Muscle Implants?

Should I get my implants over or under muscle? I am recieving conflicting opinions from plastic surgeons.
For flat breasts, breast implants work best under the muscle.
1) We individualize based on the anatomy. For relatively flat breasts with no excess skin (like yours), I think under the muscle is better (more of your own tissue covering the implants).
2) When you are trying to correct some sagging with implants, then over the muscle generally better (implants fill skin envelope better if they are over the muscle).
3) For body builders, always over the muscle.
Breast Implants - Above or Below the Muscle?
This may be a somewhat controversial statement, but in my opinion there currently is really only one acceptable position for breast implants in an elective cosmetic surgery patient: behind the pectoralis major muscle (sub-pectoral augmentation). There are a number of very compelling reasons to place implants behind the pec major, and the most compelling one of all is the fact that radiologists report that the mammographic imaging of breasts for the purpose of breast cancer screening tends to be more easily accomplished when breast implants are sub-pectoral (compared to pre-pectoral, also referred to as the 'sub-mammary' position). An American woman's current lifetime risk of breast cancer is approximately 1 in 8 to 1 in 9, so the issue of breast cancer screening must be taken very seriously. Mammography is by no means a perfect screening study, but it is the standard of care at this point in time. The most sensitive and specific test for breast cancer is a contrast-enhanced MRI scan, and breast implants do not impair breast tissue visualization by MRI.
The next very compelling reason to select sub-pectoral placement is a cosmetic one. Implants placed on top of the pec major tend to stand out in the upper pole of the breast, creating a rounded, convex and distinctly unnatural-appearing breast profile. With implants in a sub-pectoral position, the upper pole of the implant is flattened somewhat by the muscle, helping to create a smooth transition from the area in the upper chest where the breast begins, and a gradual slope towards the nipple that is not excessively rounded or convex. In some patients with a fuller breast volume preoperatively one may get an acceptable appearance with pre-pectoral placement - initially. The problem is that as breasts age, the fatty tissue atrophies and breast tissue thins out, and the area where this is most obvious is in the upper pole and cleavage area. So a pre-pectoral implant that was initially well-concealed may, after a few years, become painfully obvious (including visible implant folds and ripples) in the upper pole.
'Under the muscle' and 'sub-pectoral' are actually somewhat misleading terms, as in most cases the implant is only partially subpectoral. The anatomy of the pectoralis major muscle is such that it is actually just the upper/medial half of the implant that is covered by the muscle, while the lower/lateral half of the implant is submammary. The pectoralis major thus provides an additional layer of tissue to conceal the implant in the most cosmetically significant area of the breast: the cleavage area. This is why saline implants are often easy to feel laterally, as they are covered by breast tissue only in lateral aspect of the breast, and in slender patients who have small breasts preoperatively the implant is often immediately under the skin in this area.
Breast implant placement
There are various factors regarding how you want your breasts to look and feel, but if you and your doctor have a good, open line of communication, you shouldn’t need to go back and forth on your decision. A major factor that effects how breast implants look and feel is whether they're inserted over or under the chest (pectoral) muscle. I do submammary and submuscular implants, inserting the implants under the breast tissue and over the muscle through an incision in the breast fold. 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.
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 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.

Different opinions on this one
personally, i place almost all of my implants under the muscle. this is usually done in a "dual plane" fashion, meaning, the upper 1/2 of the implant is covered by the pectoralis muscle, while the bottom of the implant is covered by the gland.
the main motivation for this is to help to camouflage the upper pole of the implant. a simple look at your picture shows that your ribs are quite visible. you do not have much soft tissue in this area, and using the pec to help cover the implants will help to soften the edges of the implant, and therefore camouflage the implants.
some surgeons who are older than i am, practiced in the era of subglandular implant placement. my feeling is that the trend has definitely moved to submuscular placement of the implants. that is where i would place your implants if i were doing the surgery.
Location of Breast Implants
Thank you for the question.
In my opinion, there are numerous advantages of sub muscular (dual plane) breast augmentation. This implant positioning will give you the best long-term aesthetic results and reduce the chances of complications such as significant rippling/comparability/ encapsulation and interference with mammography.
Choose the "plane" which is optimal for your situation.
Based on the photo submitted, I concur that the optimal position would be "dual plane": under the pectoralis major muscle in the superior portion and below the breast tissue in the lower pole. This plane confers the following advantages: a) better superior pole (area between collar bones and nipples) soft tissue coverage, as the pec muscle drapes over the upper part of the implant; b) lower rate of capsular contracture (scar formation around the implant); c) superior imaging by mammography. Dr. Placik has astutely pointed out that the differences between your breasts will provide more challenge for your implanting surgeon than deciding on the best plane.
Some women are better served by subglandular (over the muscle positioning) a) those who have adequate upper pole coverage, typically >2cm by pinch; b) those with a "tubular" breast, which is a constricted base with sparse breast tissue under an overly enlarged nipple-areolar complex; c) body builders whose customary chest flexing poses typically cause lateralization of the breast implants. Hope this helps.
The Unders Have It
Although the choice of over versus under the muscle is there for almost everyone, certain body types lend themselves better to under the muscle. Thin tissues on the chest wall such as yours is one of those body types. Placement under the muscle would give you a thicker implant coverage a most likely a more natural result. Also, placement under the muscle is less likely to result in tight capsular contractures, which can distort and displace implants. Good luck!

Which is Better OVER or UNDER the Muscle Breast Implant Placement
All breast implants form ripples and folds (saline much worse than silicone filled). The most attractive breast augmentation results are obtained when the implant is covered completely by your tissues. Unfortunately, women present for breast augmentation precisely because they do not have sufficient breast tissues and want more volume. To cover the ripples of the implants, they are best placed under the pectoralis muscle under the breast in the majority of women.
Implant pocket choice
First, it is a personal choice by the patient. However, a patient's anatomy may lean them in one direction versus another. If you are very thin and do not have alot of breast tissue, you may wnat more soft tissue coverage and therefore have them placed under the muscle.
Under muscle implant placement for thin women
There are of course many factors to consider but an important one is coverage of the implant. This is especially important for the upper portion of the breast, in order to smooth the transition from the chest wall into the upper breast mound and avoid a fake look. Under muscle placement is very helpful in that regard. It is important to keep in mind though that the muscle doesn't cover the side or the bottom.
