Once you’ve decided that you’d like to enhance your breasts’ shapes and sizes with a breast augmentation procedure, it’s time to choose whether you want your implants placed over the muscle or under the muscle. This is a decision that your plastic surgeon will help you with, but it’s good to know the benefits of both techniques. Placing the implant over the muscle maintains 100% of the strength of the pectoralis muscle. It also defines the sharp edges of the implant, giving the obviously augmented look that some desire. Under the muscle breast implants results in the lowest chance of infection and also lends a more natural look and feel to the breasts.
