The appearance of implants placed above the muscle, in general, tend to provide greater fullness to the upper pole and a less natural, more "augmented" look. Depending on the amount of breast tissue you have, saline implants may be more prone to showing rippling of the implant and will be more prone to capsular contracture (hard, painful scar tissue around the implant). Although I place most breast implants behind the muscle, if I have a reason to place the implant in front of the muscle, unless the patient has a significant amount of natural breast tissue, I will usually try to steer the patient towards silicone implants.Hope this helps. Best of luck.
The answer depends on how much breast tissue you have to start with. If you have very little breast tissue, then you will most likely be able to see the implant and get the "implant" look. If you have a moderate amount of breast tissue, then you will most likely have a more natural look. Consider placing the implants under the muscle or silicone implants for a more natural look and feel. Good luck!
