The choice of a round implant or a breast shaped implant (anatomical) is an area of considerable controversy.
Yet let me give you my opinion, though again I don't see that there is a right or wrong in this issue. I believe that augmentation of the breast is breast enhancement. The enlargement should be a natural enhancement of the size of the breast. Each breast will have a unique characteristic or personality which can be easily filled with a round implant or 'neutral' implant. The implant should also have a softness and flow to best match the natural breast tissue.
I like the 410 implant, which we also call a 'gummy bear' or a stable form implant, in special cases and in breast reconstruction where the natural personality and characteristic of the breast has been lost. However in augmentation the 410 can look flat in the upper part (the implant is indeed flat on top) and the highly cohesive gel can be rather firm and lack a softness and flow as in the natural breast, a more 'stuck on' appearance as one changes positions.
I would choose the higher profile round gel, and would go up at least 100 to 150cc (325cc) to see any real difference. Why such a small implant selection in France? The difference between the anatomical and the round is shape and flow. There will be dissenting views, though I hope I have helped.
Best of luck.
