For most women, the question of where the implant should go with respect to the muscle (pectoralis major) is an important one. Contrary to popular opinion (at least online) one is not necessarily better than the other. Nor does the implant location always determine how "fake" the results look. Great results can be obtained with either under the muscle (partial retropectoral or two plane) or under the fascia (subfascial). The determining factor is the amount and quality of the individual's own breast tissue, skin and subcutaneous (just below the skin) fat. The advantages of submuscular (under the muscle) placement are more implant coverage in the upper portion of the breast. So this is especially good for thin women. If your skin has been stretched out , the muscle may give more support to the upper part of the implant so that it doesn't fall forward. But if you have enough good tissue, then a subfascial placement is very natural, and undetectable as "operated on".
The subfascial implant moves with the breast, and not with the flexing of the muscle, which can be a bothersome trade-off when going under the muscle.
So a lot goes into the decision as to which implant placement is "best" for you. Your board-certified Plastic Surgeon should be able to discuss these options with you. I will be adding more information on breast augmentation in this blog, but if you want some more discussion, a colleague of mine in New Jersey has posted a pretty comprehensive intro blog.
