350cc Silicone Breast Implants: How Profile Changes Width and Projection

“350cc” tells you how much an implant holds, not what shape it is. The same 350cc silicone implant comes in different profiles: wider and flatter, or narrower and projecting further forward. In one manufacturer’s published chart, 350cc implants range from about 12.5 cm wide to about 10 cm wide depending on profile.

So two women can both choose 350cc and end up with differently shaped implants. This guide explains profile in plain terms, shows one real example, and gives you questions to ask so you can follow your surgeon’s recommendation, without needing to become an implant expert.

1. What does “350cc silicone” tell you, and what doesn’t it?

It tells you two things: the volume (350cc) and the fill (silicone gel inside a silicone shell, as the FDA explains). It doesn’t tell you the implant’s width, how far it projects forward, or its brand. Those depend on the profile and the product line your surgeon is considering.

2. What is implant profile?

Think of pouring the same amount of water into a wide, shallow bowl and into a tall, narrow glass. The amount doesn’t change; the shape does. Implant profile works the same way.

Profile names (moderate, high, ultra-high and so on) vary between brands, so the names matter less than the actual width and projection. Our guide to same cc, different profile covers the idea for any volume.

3. A real example: one 350cc implant, three profiles

Here are three 350cc smooth round silicone implants from Mentor’s published MemoryGel chart. They’re shown only to make the idea concrete; other brands publish similar charts.

Source: Mentor MemoryGel smooth round chart (Latin American site), checked November 2026. Implant measurements, not results on a body. Charts can differ by country; confirm the exact implant with your surgeon. Not a recommendation of any brand.

Same volume, but the widest is about 2.4 cm wider than the narrowest, and the narrowest sits about 1.3 cm further forward. That is the whole idea of profile in three rows.

Volume is how much. Profile is what shape that amount takes.

4. Watch for this: “Same width” can mean more volume

Sometimes the comparison is made the other way round: keep the width the same and change the profile. Then a higher profile holds more volume. In the same chart, the High profile implant that is 12.5 cm wide (as wide as the 350cc Moderate Plus) is 425cc.

So if a surgeon suggests “going high profile,” it’s worth asking which they mean: the same 350cc in a narrower shape, or the same width with more volume. Both are reasonable conversations; they’re just different changes.

5. Does a higher profile mean more cleavage?

Not necessarily. A profile name doesn’t promise a particular neckline, cleavage or cup size. The American Society of Plastic Surgeons explains that profile is chosen with your body proportions and the result you want in mind. Describe the look you want (“more fullness at the top,” “a fuller side view”) and let your surgeon explain which options could get you there.

6. Where sizers fit: deciding how much fullness you like

Profile is your surgeon’s area. How much fullness you enjoy is yours. Oumènta external sizers let you wear 350cc and its neighbors in your own clothes, so you can walk into the consultation knowing the amount you like. Sizers show volume in a bra; they can’t show the difference between implant profiles.

Drag the slider to compare the same model with no sizers and wearing 350cc external sizers in the Pocket Bra. This shows added volume, not a particular implant profile.

For more on how 350cc can look on different bodies, see what 350cc implants look like. If you’re torn between neighbors, compare 300cc vs 350cc or 350cc vs 450cc.

Make your try-on count

Wear each volume on its own day in the same outfit, following our trial routine. Take front and side photos using our try-on photo guide; the side view is where you notice how far forward you like the fullness.

Bring the photos and a note of which volume felt right. That gives your surgeon a clear starting point for discussing profile.

7. What to ask your surgeon

Size preference deserves this attention. In a study of 341 women, about one in four surveyed three months after augmentation said they would have preferred a different breast size. That’s one specific surgical group, not a general regret rate, and the study did not test Oumènta sizers. For the bigger picture, see how to choose the right breast implant size.

Educational information only. Oumènta sizers and the Pocket Bra are apparel, not medical devices. They cannot predict surgical results, show an implant profile, guarantee a cup size or determine which implant is medically appropriate. Implant measurements shown are published manufacturer figures, not a recommendation. Discuss your goals, implant choices and risks with a qualified plastic surgeon.
