Should breast implants be placed above the muscle or below the muscle? Which method is the best?
The first problem is that there is no best answer for any one person. Each person’s own physical characteristics and physique determine which method is best for them. The solution is therefore to look for an experienced and skillful plastic surgeon who can give the best recommendation for your needs.

Nonetheless, here is some useful information for you to make an informed choice.


The sub-glandular technique, also known as over the muscle placement, places the implants between the breast tissue and the chest muscle.

The sub-fascial technique involves elevating the layer covering the outer surface of the chest muscle and placing the breast implants in the space created.

The sub-muscular technique, under the muscle placement, means placement of the implant below the pectoralis major chest muscle.

The dual-plane technique, involves both the sub-muscular and sub-glandular techniques. The upper part of the breast implant is sub-muscular meaning it is placed in a pocket underneath the chest muscle, while the lower part of the implant is covered only by the breast tissue.

Do note that all of these techniques places breast implants UNDER the mammary glands, which still allows for breast-feeding.



  • Can achieve a more rounded, augmented look, which some women prefer.
  • Implants can be placed slightly closer together to achieve more cleavage.
  • The breast implants do not become distorted when the pectoral muscles are flexed, which makes a good choice for women who lift weights regularly.
  • The surgical procedure is slightly easier and perceived as less invasive. This also means that there is less post-operative pain as compared to under the muscle placement.


  • Only advisable for women who have a good amount of their own breast tissue (B-cup or larger). This is so that there will be adequate soft tissue covering the breast implants to reduce the risk of breast implant visibility (palpability) and rippling, especially over time.
  • For patients with smaller amount of breast tissue, bigger implants result in a less natural outcome. (However, different degree of projections can be chosen to suit the width of the chest to get a more natural outcome.)
  • With less tissue covering the breast implant (only skin as compared to under the muscle technique), the breast might be more susceptible to visible rippling in the future.
  • Although technology allows for better breast imaging, with or without implants, over the muscle technique is generally thought to require more mammogram views due to the shadow present.
  • Based on clinical studies, the sub-glandular technique has a higher rate of capsular contracture formation due to the constant muscle movement. Patients are advised to massage the implant to reduce the risk of capsular contracture formation.


AdvantagesThe advantages to sub-fascial technique is similar to the sub-glandular technique but with the additional features:

  • The implant is supported by a strong fibrous sheath in addition to the breast tissue.

DisadvantagesThe disadvantages to sub-fascial technique is similar to the sub-glandular technique.



  • Suitable for women with any amount of breast tissue.
  • Can achieve a more natural look with natural sloping upper poles.
  • With more soft tissue padding the breast implants, there is a reduced risk of breast implant visibility and rippling in the long run.
  • Less chance of sagging as the weight of the breast implant is supported by both breast tissue and chest muscle.
  • Less likely to interfere with mammography.
  • Reduced risk of capsular contracture formation.


  • The breast might appear to sit in a higher position until the muscle fully relaxes in about 4-6 weeks after surgery.
  • This technique might not be advisable for women who regularly lift weights as it might cause implant distortion when the chest muscle is flexed.
  • The surgical procedure is perceived as more invasive. This also means that there is slightly more post-operative pain and longer recovery time as compared to over the muscle placement.
  • Not advisable for patients with too much flabby/hanging breast skin as there is a chance of the skin hanging over the implant in the long run.



  • Combines both advantages of sub-glandular and sub-muscular techniques.
  • By releasing the attachments of the overlaying breast tissue to the pectoralis major muscle to varying degrees based on an individual anatomy, the best-looking breast can be customized to suit each patient.
  • Natural result particular for patient with very small breasts as the upper pole of the implant is covered by both the breast muscle and tissue.
  • Lower risk of the formation of capsular contracture.
  • The possibility of implant dropping is reduced as the muscle and fascia secure the implant and keep it in the right position.
  • The possibility of palpating the implant borders in reduced.
  • Lower risk of wrinkles forming on the upper part of the body.

DisadvantagesThe disadvantages of dual-plane technique is similar to the sub-muscular technique.

Given this, it is still up to your individual physical characteristics and preferences to determine which technique is best for you. Always ask to discuss all the advantages and disadvantages with an experienced plastic surgeon before making a decision.
