Trouble deciding size: 300cc or 330?!! Help! Im 165cm 50kg and thin. I want a natural look! (photos)

Hello and thank you for your question. 300 and 330cc are very close in size.  I may also advise considering submuscular placement of your implants.  There are several advantages
and disadvantages to over vs under the muscle.  Under the muscle has the
advantage of lower capsular contracture rates, less risk of rippling, and
better visualization with future mammograms.  Most patients say that under
the muscle also has a more natural look and feel.  The size, shape,
and profile 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.

Hello,Cosmetic plastic surgery is a field of medicine that is just beginning to develop and utilize data to optimize techniques and choices for better outcomes and lower complication rates. A 14 point plan has been developed and published this year in PRS, which seeks to optimize breast augmentation results and minimize complications, especially capsular contracture, through reduction in bacterial contamination, the most common negative phenomenon of breast implants. Of those 14 points, periareolar incisions and subglandular implant placement are not recommended. Instead, a dual plane/sub-pectoral placement via an inframammary incision is preferred. Regarding your goal of obtaining a 'natural' appearance, sub-pectoral placement would be preferred, as would a lower profile implant. Additionally, implant volume is perhaps the most important variable to perceived outcome: the larger the implant, the 'faker' the result. If your surgeon isn't an ABPS certified/ASAPS member surgeon who specializes in breast surgery, you may consider consulting with a few. Best of luck!
