When it comes to placement of the breast implants, there are two general positions: on top of or below your chest muscle. I typically do a combination of the two, called dual-plane breast augmentation.
Nothing in life is perfect, and the same can be said for implant position.
On top of the muscle
Advantage: More natural lift of the breast, better control to improve cleavage
Disadvantage: Implant visibility and palpability, increased risk of implant rippling
Below the muscle
Advantage: More implant coverage, so less likelihood of implant rippling. More ‘natural result’
Disadvantage: Animation deformity in which the implant moves with muscle contraction
I generally do a dual-plane placement in which the lower border of the chest muscle is released. This allows muscle coverage at the top of the implant and lets the implant settle in a natural position behind the breast gland. In my opinion, it allows for the best of both world
