What will my breast augmentation look like with 420cc tsx profiles over the muscle, inserted with the crease? (Photo)

In my opinion, implants placed on top of the muscle look
like coconut shells or a rock in a sock.
This is not consistent with my personal aesthetic, but I nonetheless wish
you the best of luck.

Every patient is different. You need to schedule an appointment with Board Certified PS, be examined and a Surgeon will outline a treatment plan that is right for you based on your measurements.You also need to look at the before and after photos of that surgeon. There is no direct correlation between a cup size and implant size. Best to go by what looks and feels good. During your appointment you will go through a sizing process that will help you choose the right implants.

Thank you for your photo and questions. Cup size is unfortunately an imprecise measure because this varies among bra manufacturers. That being said, based on your frame and current size, you will likely have a significant increase in size and be around a D-DD cup with a ~400cc implant, and you will likely look 'busty' but not abnormally out of proportion. I must defer to the judgement of the surgeon who examined you, but placing a large implant on top of the muscle in someone with relatively small breasts increases the risk of implant palpability and rippling so I hope this was discussed with you. I hope this helps!

Your photos demonstrate a tuberous breast deformity. If your PS did not address this with you in the operative planning, get a second opinion. Good luck and be well.

The best cosmetic result in
any particular breast augmentation patient depends on a variety of factors,
including: your individual anatomy, desired outcome, realistic expectations, a
thorough discussion with the plastic surgeon about the options, and an
understanding of the pros and cons of any particular implant choice. Proper
sizing is not just about the number of cc’s. The thickness of your tissue,
breast dimensions which include the width, height, and projection, as well as
chest wall width all need to be considered when choosing an implant. Trying on
implant “sizers” of various shapes and volumes while wearing a tight t-shirt,
bra, or bathing suit at a preoperative visit will help you and your surgeon
choose the optimal implant.Keep in mind that following
the advice from a surgeon on this or any other website who proposes to tell you
what to do without examining you, physically feeling the tissue, assessing your
desired outcome, taking a full medical history, and discussing the pros and
cons of each operative procedure would not be in your best interest. I would
suggest you find a plastic surgeon certified by the American Board of Plastic
Surgery and ideally a member of the American Society for Aesthetic Plastic
Surgery (ASAPS) that you trust and are comfortable with. If you live outside of the United States, the surgeon should
ideally be a member of the International Society of Aesthetic Plastic Surgery
(ISAPS).  You should discuss
your concerns with that surgeon in person.Robert Singer, MD FACSLa Jolla, California

The proper evaluation includes skin quality and tightness. The size of the implant may or may not fit to your desires. It is important to have a board certified plastic surgeon evaluate you to see what will work for your situation.
