Partial Muscle Coverage

All materials in this video can be downloaded below

Partial Muscle Coverage

With Partial Muscle Coverage, the pectoralis major muscle is used to cover just the top part of the implant, leaving the lower portion of the implant uncovered. Without muscle constraining the lower part of the implant, the bottom portion of the implant is kept free, supported by existing breast skin only. This may help to provide more natural looking ptosis, or hang to the breast. Partial muscle coverage addresses some of the drawbacks of full muscle coverage breast reconstruction with implants, but may create a different set of risks and concerns.

In addition to the potential advantages and disadvantages listed in the Breast Implant Reconstruction page, other potential advantages and disadvantages of Partial Muscle Coverage are also outlined here.

Potential Advantages | Potential Disadvantages

Potential Advantages

  • Helps to achieve a more natural looking breast shape and contour (by keeping lower part of implant unrestricted by muscle)
  • Better defined crease where the breast naturally hangs
  • Greater breast projection, the way the breast hangs and points

Potential Disadvantages

  • "Bottoming out" of the implant - risk of implant moving downward, falling below the natural crease of the breast towards your waist
  • Lateral malposition – implant can shift sideways, toward your side
  • Exposure and extrusion of implant – the weight of the implant can stretch your skin to the point that it breaks through the skin itself
  • Symmastia – implants can move towards one another resulting in the breasts possibly touching in the middle
  • May be able to see or feel the implant through the skin
