Can’t decide on cc size. I’m thinking 420cc or 430cc, high profile and under the muscle. Thoughts?

Thank-you for your question.
Choosing the correct breast implants may seem overwhelming due to the options available for implant material (silicone or saline), placement (under or over the muscle), implant size and shape. Treatment plans are individualized for each patient based on findings during the consultation to meet your goals. 
Selecting the correct implant size and shape is among the most important decisions in a successful breast augmentation procedure. Placement of the identical implant will not produce the same results in all patients due to differences in:
1.Dimensions of the breast 
2.Diameter of the chest 
3.Volume of breast tissue 
4. Height and weight 
5. Breast shape, including breast ptosis and asymmetry
I rely on 3 methods to advise my patients:
1. Dimensional planning 
2. Gel implant sizing 
3. 3-Dimensional Vectra imageing system.
At the time of consultation, measurements are taken allowing for dimensional planning to select the implant which best fits the base diameter of the breast. Gel implant sizing is performed to allow you to visualize augmentation the with the various sized implants. Vectra 3-D imaging has been a very important method in my practice in selecting the correct implant size and shape as it allows you to see what you will look like following augmentation with any of the available implants. I would recommend a consultation with a Board Certified Plastic SurgeonBest regards, Andrew Lyos MD, FACS

Breast implant type and sizing selection is a complicated process and requires a detailed consultation that includes a discussion of your goals, a detailed examination, and a lengthy discussion. But the decision will always start and end with the patient. When it comes to sizing, 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 it is 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, every one of them has 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 discuss your concerns with a board-certified plastic surgeon and make sure that your surgeon understands your goals.
