Should I go bigger than 300c moderate under the muscle silicone round implants? To achieve the results I love (Photo)

Hello and thank you for your question. You are a great candidate
for a breast augmentation.  300cc or slightly larger may be realistic for you to achieve your goals.  The size, profile, and shape of the
implant is based on your desired breast size/shape, your chest wall
measurements, and soft tissue quality.  This decision should
be based on a detailed discussion with equal input from both you
and your surgeon.  This entire surgery
can be performed with a small incision technique.  Make sure you
specifically look at before and after pictures of real patients who have
had this surgery performed by your surgeon and evaluate their results.   The most important aspect is to find a
surgeon you are comfortable with. I recommend that you seek consultation with a
qualified board-certified plastic surgeon who can evaluate you in person.
Best wishes and good luck.

Achieving the perfect size can't be determined via online questions.  This would need to be determined and a lengthy and thoughtful consultation, showing pictures, trying on sizers, etc.  Everyone holds the volume differentlyBest of luck!

First, from photos alone and without a clinical exam, it is really hard to know which size is going to help you achieve your goals.  From the photo that you provided, I would say that 300 cc is not going to allow you to establish this much of a volume increase.  Also, I would discourage you from the moderates since they tend to be wider and, in my opinion, give much less lift and shaping for my younger patients.  In my practice, we employ a formalized plan that helps our patients achieve their desired size and shape which includes the following:In-person consultationBreast measurementsDiscussion of goals Pre-operative meeting to review photos (2-3 that you bring in demonstrating a volume relationship that you find attractive) and choose a style of implant and size rangeUse of implant sizers in surgery to actually see what specific volumes accomplish with your specific tissueI have found that this approach generally allows us to be very specific in terms of identifying what it is that you want and what we can actually accomplish with various implant styles and sizes.Above all, make sure and meet with a Board Certified Plastic Surgeon who specializes in breast enhancement.  Who you choose for your initial surgery makes all the difference in terms of outcome not only for your first surgery but also potentially for any additional revisions down the road.I hope that helps and wish you the very best!-Gregory A Buford MD FACSBoard Certified Plastic Surgeon and Author
