Is there a noticeable difference between 405cc moderate classic and 425cc moderate classic?

20cc.  (!!!)Only kidding. I do not think you will be able to tell the difference between the two if they are the same profile (ie both moderate classic). Congrats on your decision and good luck.

The difference in volume of 20cc's is the equivalent of 4 teaspoons. So I don't think you will notice a difference. When my patients are trying to decide between to different sizes, I recommend the larger implant. Good luck!

A 20 mL difference with the same style of implant will not make a significant visual difference.  Generally, if you are between sizes I would recommend you choose the larger of the two.  Good luck 

I tell my patients that if they really want a noticeable difference, then 50-100cc will be visible. I think that a 20 cc difference will be barely visible. If my patients have difficult choosing between 2 sizes then we suggest they choose the larger size, if it is reasonable for their frame. All implants look slightly smaller once they are inside and once the swelling has gone down. In our office we have Crisalix, for 3 D imaging so you can see what you may look like between the two sizes. We even have virtual reality goggles so that you can look down at yourself, to see the switch between the two sizes instantaneously. It is super fun and patients are truly amazed with the goggles. I always get a chuckle out of their responses. Make sure to see a board certified plastic surgeon with lots of experience.

Hello and thank you for your question.  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.

Thank you for sharing your question.  In most patients a 20cc difference will not make a material difference in the outcome of a patient's breast augmentation.  As both sizes are likely appropriate for your frame I would select the implant that looks best when you try the sizers on.  Best wishes.

Dear Katie,  I already responded to your questions yesterday. Based on your picture, 425 cc will get you to 34 C plus size, but not full C and definitely not small D cup. Check my recommendation to you in my previous response.               Best of luck,                                      Dr Widder      

Thanks for your question. When you increase a size in the same style of implant you change the width more than the projection. So a 425 will be taller and wider. One size up will not make a huge difference. If you like the diameter of the 405 but you want more projection (not height) then you may consider a moderate plus of the same or similar diameter.In General I recommend finding the implant whose diameter has enough curve to balance with the curve of the hips, and then play with the projection that fits your goals.I have included faq of this approach below. hope it helps.

There is a very slight difference in the diameter of these implants and in many cases would not be noticed by a woman. Often larger differences would be required to make a significant change in fullness postoperatively. There are many other factors and forces within healing that can determine breast size and breast shape. The various profiles of breast implants can also change the relative lateral fullness versus projection forward of implants. There are also limitations in anatomy with regards to sizing and shaping of implants. A good discussion with your surgeon regarding your goals and also what is possible sound in order.

It's all good. You can't go wrong with 405 or 425 ccs because the 20cc difference is a hair more than a tablespoon, or equivalent to one notch on your bra strap. Hope this information is reassuring. For more information on this and similar topics, I recommend a plastic surgery Q&A book like "The Scoop On Breasts: A Plastic Surgeon Busts the Myths." Good luck to you.
