Breast implants can be placed in three distinct locations within the breast during breast augmentation surgery. These are normally termed as completely submuscular, subglandular, and subpectoral.

The 2 Different Implant Placements

Let’s take a look at each of these to better understand why your plastic surgeon might recommend one placement over another.

Completely Submuscular

This is normally reserved for the placement of a tissue expander in breast reconstruction. What this implies is that the implant is entirely covered by chest muscles. Both the pectoralis major and serratus anterior muscles are elevated off the chest wall to enclose the implant entirely.

The reason to choose this approach is that often the skin integrity is compromised in a mastectomy and there is a high risk of skin loss and implant exposure. If this occurs in breast reconstruction, it normally leads to the removal of the implant and the need to start all over again. The underlying muscle is healthy and vascular, this may help in preserving the implant if the skin fails to heal.

This approach is almost never used in cosmetic breast augmentation. The aesthetic outcome of this may be compromised since the implant can appear too high and out of balance within the breasts.

Subglandular

This implant placement is the second most common in the US. Space is located above the chest muscle layer, but immediately beneath the breast itself. It allows the proper location of the implant immediately behind the breast and there are no restrictions related to the underlying muscle anatomy.

This placement provides the most direct impact of the implant on the breast to slightly elevate the nipple and areola without a lift. There is also no muscle related distortion of the underlying implant that is frequently termed as animation deformity, where the implant can move with contraction of the pectorals muscle. Finally, this is the least painful placement since the muscle is not manipulated that is usually the result of the majority of the postoperative pain.

The boon that is usually associated with this approach is that the implant is potentially more visible since the pectoralis muscle does not cover the implant. This results in a higher risk of implant rippling seen through the skin. Thus, the ideal candidates for this approach are those who have some degree of preexisting breast tissue to help hide the implant.

Additionally, the incidence of capsular contracture is significantly higher with this placement location. As capsular contracture is one of the most challenging aspects of breast augmentation surgery, this risk alone is enough to avoid this approach in most women.

Subpectoral

This is the most common approach used for breast augmentation by plastic surgeons. It is also frequently associated with the dual plane technique.

A dual plane surgical technique is an approach that separates the breast tissue from the pectoralis muscle but still keeps the implant largely in a submuscular position. The implant resides in a “dual plane” where the top two-thirds are covered by the pectorals, and the bottom third is covered by the breast tissue alone. This allows for the possibility of improvement in breast asymmetry and can result in a mild enhancement of a lift seen at the nipple and areola.

The major benefit of a submuscular placement of a breast implant is that it recruits more “soft tissue” to help hide or camouflage the underlying implants making the result more “natural” with less of a risk for visible rippling. In addition to this obvious benefit, the risk of capsular contracture is threefold less with this approach. This is significant and provides a more long-lasting reliable result for most women. Finally, mammograms are more easily read by radiologists as there is not a risk of the implant obscuring breast tissue hidden beneath it while remaining over the muscle layer.

In a subpectoral approach, all of the breast tissue sits above the muscle or implant itself. However, some negative aspects still exist with this approach. Firstly, the elevation of the muscle during surgery will frequently lead to more pain in the early aspect of your recovery. This is temporary but to be expected. Also, there is a risk for animation deformity where the breast or implant will move with contraction of the pectoralis muscle. This does not happen to most women but is more significant versus a subglandular approach. While exercising or contracting the pectoralis, the implant can move and women may find this to be unfavorable.

Choosing the best implant placement for you

When choosing the best location for the breast implant, you must consider this to be a compromise of different techniques with individual pros and cons. This should be individualized with both the patient and surgeon after a lengthy discussion about your specific options in light of your anatomy, desires and risk tolerance.

Fortunately, breast augmentation is a very successful surgery and one with many happy patients when performed by a Board-Certified Plastic Surgeon. To see if you are a candidate for breast enhancement surgery, contact our San Diego office at 858-638-9800 to schedule your in-person consultation.
