When performing hybrid breast augmentation (a combination of silicone implants and fat grafting), one of the most crucial aesthetic points is the décolleté and cleavage line.

Rather than simply enlarging the breasts, the goal is to create a natural, three-dimensional contour from the sternum to the upper chest that enhances the entire body silhouette.

Who Is This Suitable For

• Those who wish to reduce the appearance of prominent ribs.
• Those who feel their cleavage is too wide or the breasts are positioned outward.
• Those who want a smoother transition between the implant and the chest wall.

In these cases, fat grafting to the cleavage and décolleté area can be highly effective.

By supplementing this region with fat, it is possible to soften the skeletal appearance and create a smooth, natural transition between the implant and the skin, resulting in a more feminine and balanced upper body line.

Medical Considerations

While this area is aesthetically important, it is also one of the most challenging regions for fat survival.

Although it is the area where patients most desire long-term volume, the fat retention rate tends to be lower compared with other parts of the breast.

Key reasons include:

• The décolleté region has relatively poor blood flow, making fat engraftment more difficult.
• Constant movement and pressure changes in this area increase the likelihood of resorption.
• The thin tissue layer between the skin and implant limits the amount that can be safely injected.

For these reasons, precise planning of the injection layer, amount, and angle is essential.

Overfilling this area may lead to complications such as oil cysts or fat necrosis.

Case Example

The patient below is shown one month after hybrid breast augmentation.

Despite some resorption compared to immediately after surgery, the cleavage and décolleté area has retained a soft, smooth contour, producing a naturally enhanced bust line.

Many patients feel that some additional volume would be ideal, which is a normal and expected process during the healing period.

Summary

In hybrid breast augmentation, the distribution and technique of fat grafting are as important as implant selection.

At AVAN TOKYO GINZA LIPOSUCTION CLINIC, our surgeons—highly knowledgeable in breast anatomy and vascular physiology—perform precisely designed, layer-specific injections to achieve both safety and beauty.

For those who desire a natural, refined bust and a beautifully contoured décolleté that complements their body line, hybrid breast augmentation may be the ideal choice.
