Will 460 ccs high profile silicone implants over the muscle give me a tennis ball look?

Hello Thank you for your question. Going under the muscle will give you a more natural look, as well as help to keep the implants in place. Best regards

While this may be a choice most will go below the muscle for better coverage and support and lower capsule contraction rates. I would consider another consultation. Posting pics will give us more to evaluate as well. Good Luck!
