Subpectoral Breast Implants

Subpectoral breast augmentation, characterized by a partial placement of the implant under the muscle, is very common in the US. With the sub pectoral method of breast augmentation, a breast implant is located below the chest muscles at the top of for 2/3, and the base of the breast implant is supported by breast tissue.

Advantages of subpectoral breast implants

The main advantages when placing breast implants partially under muscle, partially under breast tissue (subpectoral placement breast augmentation) are:

a) A more complete visibility when mammography for breast (unlike subglandular placement).

The pectoral muscles actually pushes breast tissue. Breast implant and mammary tissue when subpectoral breast augmentation do not contact with each other (except for the lower part of the breast).

b) Forming a natural form in the upper pole of the breast that looks more natural. This method does not deny the probability of obtaining “artificial” breasts as a result of incorrectly chosen size, profile and surgical approach, so to get the perfect natural breasts a final decision about the choice of these parameters must take a surgeon. Trust only the professionals and you will get a WOW-effect of the new breast!

Low probability of occurrence of irregularities and expressed edges of the implant. Often, patients seek to replace the implants due to wrinkling of the skin of the breast after breast augmentation.

Placement of breast implants only under the glandular tissue increases the risk of irregularities, so the patient with a small amount of breast tissue and / or thin skin should choose a subpectoral, or axillary location, if there is no definitive indication to another method.

The risk of developing capsular contracture with subpectoral placement of the implant under the pectoral muscle less than when placed above the muscle.

Disadvantages of subpectoral augmentation mammaplasty

Subpectoral Implants

  1. In the early postoperative period discomfort persists a little longer
  2. Limiting the size of breast implant. This does not mean that only a small breast implants can be used with a subpectoral placement. This means that very large implants can not used from the first time with this method of breast augmentation.
  3. Possible distortion of the implant, placed under the muscle, if significant physical activity (for example, if you are a bodybuilder).
  4. Subpectoral breast augmentation is characterized by a little more time for reaching the final result (when the implant is completely “get up” into place).
  5. If you have a predisposition, part of the implant located underneath the skin, promotes earlier ptosis
  6. When excess dissection of the pectoral muscles by doctor error, there is a risk of complication – symmastia.

Health of each patient and the achievement of the maximum result of the patient’s wishes – the priority of the work of clinics.

Subpectoral breast implants: Pros and Cons

The upper part of the implant partially under the muscle, lower just under the breast tissue


  • The risk of capsular contracture is less
  • Less likelihood of visualization regions and occurrence of implant wrinkling in the upper chest
  • Formed more natural shape of the upper part of the breast that looks more natural

  • The recovery period is longer (discomfort lasts longer)
  • The implant can be visualized with considerable physical effort on your hands (breast shape is distorted)
  • However, it is only under severe loads on the pectoral muscles
  • It takes a long time after surgery order to implant “down” and “got up” into place (it takes more time to form a complete result of the operation)
  • The part of the implant is anyway under the skin, which may lead to earlier breast ptosis

    I am 20.5 weeks out from my tummy tuck and 6 weeks away from my breast lift and augmentation. I am 5’3″ and about 138 pounds. And after losing 100pounds twice in the last 5 years and having 2 babies I’m ready to fix the girls. My dr. Showed me 350CC implants but suggested we go a bit smaller at 325CC for my body type/Frame. I am in a 34 D right now but a ton of padding so I am super deflated. So it’s possible that I am a full C (I live in Japan and nowhere to get properly fitted) anyone else with similar stats have 325CC. *I’m leaning towards under the muscle.

    I am 5’3″ but weigh more than you. However I am going 450cc under. Mod+

  3. Faren says:

    I am 5’6 – 130lbs. I was a bit smaller in the chest pre op, but same amount of sag and deflation as you. I went with 400cc under the muscle high profile. I am now a 34dd. I had the implants 3 months ago, and headed for the lift in 3 more months.

    I’m 5’2 135 pounds I started as a 34B and got 545 high profile silicone and am now a 34DD

    I’m 5’2 about 130lbs I have 425cc on top and I am a 34dd

  6. Alana says:

    Thank you to all for the info! A D cup would be perfect for me so maybe the 325cc-350cc would be a great choice for me. I am beyond excited. I can’t believe this is finally happening. My mommy makover will be complete!

  7. Dione says:

    I thought that 325 would be tiny on me but as youre already having a lift and have a lot of tissue it’ll still look large.
    I had 310CC uhp implants over the muscle with a full uplift and they’re definitely bigger than i thought which is great as i was soo worried they’d not be big enough.

    I had a mommy make over. I’m slightly smaller than you. 5ft 110lbs. I got 375 high profile Silicone unders. I love them but kinda wish I went even bigger
