Dual Plane Placement of Breast Implants

There are two main placement options with breast implants: over or under the chest muscle.

If you’re choosing to have your implants placed under the chest muscle (pectoralis major) you may have heard of something called dual plane placement.

Dual Plane

Despite sounding like it, this has nothing to do with aeronautics! Instead, it’s all about where under the muscle your implants are placed.

When you think of an implant under the muscle you wouldn’t be alone if you imagined that it was placed completely under the muscle.

There aren’t many surgeons though who will place implants fully under the muscle. Instead, most implants in the ‘under’ placement are only partially under the muscle.


Implants are partially under the muscle because the top part is under the pectoral muscle and the bottom part is under the breast tissue.

So, really, when we say submuscular when we’re referring to unders it’s not actually technically correct! We should be saying subpectoral, because unders are only partially under the pectoral muscle… not the whole chest muscle.

With dual plane, your surgeon tailors the placement of your implants with varying degrees of muscle release/separation from the breast tissue in order to vary the amount of muscle/breast tissue coverage.

Choosing Dual Placement

Depending on which order you make the key breast implant decisions (location, incision, type, size, shape) it’s worth knowing that implants in the dual plane location can only be placed via a nipple (areolar) or underboob (inframammary fold/crease) incision.

Dual plane placement works well if you have slightly droopy breasts because the surgical technique involved can give the illusion of a little lift to the breasts.


To fully understand what dual plane means you’d have to understand a bit about the muscle anatomy of the chest wall. If the thought of anatomy 101 gives you the shivers and your surgeon is recommending the placement of your implants ‘under the muscle’ just ask them to tell you how much under the muscle.

Basically, dual plane is a form of under the muscle or, more accurately, subpectoral placement.

The bottom line with any breast augmentation surgery is that you need to go to a Board Certified plastic surgeon who does excellent work. Whatever placement option they recommend should come with a full explanation of the benefits, so you can make an informed decision.

Hi, ladies!

I am so glad you're here, because I know exactly how it feels to look in the mirror and feel self conscious.

That was the story of my life until I made one of the best decisions of my life—getting a breast augmentation. I want you to know that there is no shame in you considering breast implants, and you are absolutely worth the investment.

If you're ready to LOVE the reflection you see in the mirror, then I'm here to guide you every step of the way!
