Will 500cc implants under the muscle look small?

The implant selection should be based on a combination of your desired size, soft tissue dynamics, breast base diameter and skin elasticity.  I recommend an in-office examination as well as a detailed discussion with a surgeon who you are comfortable with.   Finally, make sure your surgeon is a Double-Board Certified Plastic Surgeon certified by the American Board of Plastic Surgery (ABPS), a member of the American Society of Plastic Surgery (ASPS) and the American Society of Aesthetic Plastic Surgery (ASAPS).Best,Dr. DesaiBeverly Hills Institute for Aesthetic Plastic SurgeryHarvard Educated, Beverly Hills & Miami Beach Trained, Double-Board Certified Plastic Surgeon

I routinely perform a 3-d simulation for all of my breast augmentation patients in order to properly assess and size each patient so they are ultimately happy with their final size and profile. 

Hello and thank you for your question.  The
best advice you can receive is from an in-person consultation.  500 and 600cc implants are large implants.  Pictures would be very helpful in making this decision.  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.   
Best wishes and good luck.

Dear Meganjimenez,determining the ideal breast size and matching that goal for the patient is the most difficult part of breast augmentation. It starts and ends with the patient. We have all of our patients find 3 photos of their desired breast size. We ask for naked breast photos because clothing can obscure the true size (push up bras). Next, we consult with patients and go over the photos and take detailed breast measurements during a physical exam. Next, we using a sizing algorithm to determine a range of implants that will work based on the exam and the measurements. Lastly, during the operation, we use silicone sizers in the operating room to see how the size actually looks in the breast. We sit the patient up in the operating room, while asleep of course, and compare the sizer result with their desired look photos. If its too small, we start the process over with a slightly larger implant. We don't stop until we get the perfect match. Of all of my breast augmentation patients, everyone of them have been happy with their size due to this detailed and meticulous process. You don't want to invest time and money into a result that is either too big or too small. You should spend some time discussing it with your plastic surgeon.Daniel Barrett, MD, MHA, MS

It is difficult to counsel you without an exam, photos or measurements of your chest wall and breast configuration.We use surgical simulation software in our office to take a lot of this kind of guesswork out. Did you use a sizer in the office? How did you and your surgeon arrive at the implant size? Was it just exam and conversation or did you use any other objective method like the above to narrow the search?

500cc implants are big....We need photos of what your chest looks like and need to know what size you want to be so we can best help you. Please review the before/after photos of the doctor you are working with to make sure you like their work and find photos of patients that look like you with 500cc or 600cc implants to see if you like how they look.  Andre Aboolian, Plastic Surgeon, Beverly Hills, andreaboolian.com

you can easily accommodate larger implants and the easiest way to visualize this is to use external sizers.  So a sizer in your unlined bra 450 cc in size would simulate what you are desiring with the 500 cc implant as I always add 10% to my implants from whatever sizer my patients like.  And a 550 cc sizer will give you the look of the 600 cc implant.  See what works on your frame and choose what is best for you.  I would speculate you would be better with the 600 cc size.

Just as beauty is in the eye of the beholder, so is the concept of "large." I would suggest that you visit your plastic surgeon and have him/her try sizers in a bra and that you slip a top on and look in the mirror. Decide what size of implant works for you. 
You might also find photos that demonstrate your appearance goal and that your plastic surgeon could have in the OR to help him/her during the procedure. Alternatively, breast imaging may help you decide on implant size.
With all of that said, sometimes what can be done in surgery is not what one hopes for, so a degree of flexibility on your part helps to avoid disappointment.
Best of success!

Thanks for your question- your height and weight are helpful, but not enough information to get you a reliable answer.  Sizing for breast implants is a complex issue and helping patients figure out the right size is one of the aspects of  plastic surgery that requires expertise on the part of the surgeon.  Many surgeons do things differently, and so it's hard to give an opinion about your surgeon's advice.  Largely it also depends on how you want to look- athletic?  proportionate? full-breasted?You should seek out a surgeon who's before and after photos look like you you want to look, and then get a consultation that provides you with a comfortable plan.   For example, with my patients I don't make women choose an implant size at all.  I have them use sizers and a bra to show me how they want to look, and I use intra-operative sizers during the procedure to see how various implant volumes and shapes appear in order to achieve their postoperative goals.  That way there is not a lot of uncertainty by the patient regarding which implant size they have chosen.  They rely on me to get them the look that they want based on my techniques and attention to their wishes.  I tend to get it right :)My way is no better or worse than other successful surgeons, it's just how I do things.  Some surgeons use 3D imaging, other surgeons go only based on measurements.  With my sizing and operative techniques I end up basically never doing revisions for size (rarely at all for anything), and it works for me.  A good, experienced surgeon with a low revision rate, good before and after photos, and a great reputation should provide you with a consultation and a plan that you are comfortable with.Best wishes,Dr. L

The ideal Implant size cannot be determined by height and weight alone. It is best to have an in-office evaluation so that careful measurements can be taken to determine the best size implant for your chest diameter, several upper body measurements, and current breast tissue. Once you have the measurements, they are all put together to determine the right implant from the right manufacturer. Breast implants of the same cc's can look and feel extremely different depending on the profile and material. That being said, implants in the 500-600 range are considered large to very large in most patients. Hope this helps!
