Which Breast Implant Placement is Least Likely to Cause Sagging?

 Placement behind the muscles is the better option.  When the implant is placed in front of the muscle there is more risk of the skin stretching and sagging, as others have said, like a rock in sock.  Good luck with your surgery.

There are ways to prevent bottoming out of breasts (see video) Placing the breast implants behind the muscle can help. But, the size of the implant and placement on the chest wall are also very important.   In my opinion, all breast implants should be placed behind the muscle.  and there are two compelling reasons behind my opinion. First, radiologists have let us know that they can best image breast issue mammographically when an implant is in a subpectoral compared to a submammary position. Another compelling reason is aesthetic. The pectoralis major muscle serves as an additional layer of soft tissue coverage for the upper pole of the implant, and it tends to flatten the upper pole of the implant somewhat creating a very smooth and natural appearing contour to the upper pole.
