Implants, particularly breast implants, are primarily measured by their volume in cubic centimetres (cc), not by bra cup size. This method provides a precise and standardized way to quantify implant dimensions.
Understanding Implant Measurement
The most crucial measurement for implants, especially breast implants, is their volume, expressed in cubic centimetres (cc). This scientific unit allows for consistent and accurate sizing, which is vital for achieving desired aesthetic outcomes and ensuring a proper fit within the body.
The provided reference highlights this key fact: "Implants are measured in volume, cubic centimetres (cc), rather than the cup size. A smaller breast implant can range from 150 to 200cc." This emphasizes that traditional bra cup sizes are an unreliable metric for implant sizing due to their variability across brands and lack of direct correlation to implant dimensions.
Why Volume (cc) is Preferred Over Cup Size
- Precision and Standardization: Cubic centimetres provide an exact volumetric measurement, allowing surgeons and patients to precisely understand the amount of space an implant will occupy. This standardization is critical for surgical planning.
- Predictability: Using cc helps predict the approximate post-operative size increase more accurately than ambiguous cup sizes.
- Individual Variation: Bra cup sizes are highly inconsistent and depend on numerous factors, including band size, breast tissue density, and bra brand. A 'C cup' from one brand might be different from another, making it an unhelpful measure for implant sizing.
Other Important Implant Dimensions
While volume (cc) is the primary measurement, surgeons also consider other dimensions to ensure the best fit and aesthetic result for the individual's anatomy. These include:
- Base Width (Diameter): This refers to the width of the implant's base, which must correspond to the natural width of the patient's breast and chest wall. An implant that is too wide or too narrow for the breast footprint can lead to unnatural-looking results.
- Projection (Profile): This describes how far the implant projects forward from the chest wall. Implants come in various profiles, such as low, moderate, moderate plus, and high, allowing for different levels of projection and fullness.
- Height: The vertical measurement of the implant.
- Shape: Implants are typically available in round or anatomical (teardrop) shapes, each providing a different contour.
Common Breast Implant Sizes by Volume (cc)
To illustrate the range, here's a general guide to common breast implant volumes and their typical perception:
| Implant Volume (cc) | General Perception | Approximate Bra Cup Increase* |
|---|---|---|
| 150 - 250 | Smaller/Subtle | 0.5 to 1 cup |
| 275 - 375 | Medium | 1 to 2 cups |
| 400 - 550 | Larger | 2 to 3 cups |
| 575+ | Very Large | 3+ cups |
*Note: The approximate bra cup increase is a general estimate and can vary significantly based on existing breast tissue, body frame, and individual bra brands. It is not a precise measurement method for implant sizing.
Practical Insights
- Consultation is Key: During a consultation for breast augmentation, a surgeon will use sizers (external molds mimicking implant sizes) to help patients visualize and choose the ideal volume and profile that aligns with their desired outcome and body frame.
- Balance and Proportion: The goal of implant measurement is to achieve a balanced and proportionate look that complements the patient's overall physique, rather than simply focusing on a specific cup size.
- Material and Type: The measurement principles (volume, width, projection) apply regardless of the implant material (e.g., saline, silicone) or shell type.
