370cc biconvex gluteal implants: clinical case of hybrid gluteal augmentation
Some anatomies cannot be corrected with a single procedure. In this case, the patient presented with square buttocks, an undefined waist, and a lack of midsection projection. Therefore, the goal was not only to increase volume but also to transform a straight silhouette into a more curved and harmonious figure.
To achieve this, a hybrid buttock augmentation with 370cc biconvex gluteal implants360° liposuction and subcutaneous fat transfer. This allowed for greater projection, a defined waist, and a smoother transition between the torso and buttocks.
The essential things you need to know
- Biconvex buttock implants allow for a more powerful central projection than standard designs.
- In this patient, 370cc implants were used in a double plane position.
- In addition, 360° liposuction was key to creating a waistline and visual contrast.
- Fat transfer helped refine the contours and smooth the transition with the implant.
- Therefore, this type of result would not have been possible with fat alone.
Clinical case: 370cc biconvex gluteal implants + hybrid BBL
The starting anatomy: why fat alone wasn't enough
During the assessment, three important features were observed: square buttocks, a virtually nonexistent waist, and limited central projection. In addition, the lateral transition was poor, so the silhouette did not create the hourglass contrast the patient desired.
In this type of anatomy, a single fat transfer is often insufficient. Therefore, the surgical plan had to combine structure, waist definition, and surface refinement. Thus, implants provide projection, liposuction creates contrast, and fat transfer improves the contour's finish.

The procedure: 370cc biconvex gluteal implants + hybrid BBL
Biconvex implants 370cc
Their curvature on both sides allows for powerful central projection. Therefore, they are useful for buttocks that are square, flat, or have little structural projection.
Double plane position
Deep placement improves implant stability. It also helps achieve more natural movement.
360° Liposuction
It defines the flanks, abdomen, and lower back. As a result, it creates the necessary concavity for a more defined waist.
Subcutaneous fat transfer
The fat is placed in the subcutaneous plane. Its function is to soften edges, improve the transition, and refine the result.
Why was the change in silhouette so noticeable?
The transformation didn't come solely from added volume. In reality, the change occurred by removing volume where it created a boxy shape and adding structure where curve was lacking. Liposuction created the contrast, the implant provided the projection, and the fat refined the transition.
Do you want to know if hybrid buttock augmentation is right for your anatomy?
The choice between a BBL with fat transfer, buttock implants, or a hybrid technique depends on your starting point. A personalized assessment will help determine what results are realistic for you.

Do biconvex buttock implants cause capsular contracture?
This is a common question, especially since many patients are familiar with capsular contracture in breast implants. However, the situation is different in buttock surgery. Clinically significant capsular contracture in buttock implants is extremely rare.
While there is no single explanation, two factors likely play a role. First, the gluteal region has a high vascularization. Second, the buttocks are in constant motion when walking, sitting, or changing posture. Together, these factors create a very different environment than that of the mammary region.
The key idea
In clinical practice, capsular contracture is not the primary risk associated with gluteal implants. Instead, the risks that must be clearly explained are malposition, seroma, infection, dehiscence, or implant exposure.
Real risks that do need to be explained
- Malposition or asymmetry: Implant displacement from the planned position.
- Seroma: fluid accumulation around the implant.
- Infection: rare, but important complication.
- Dehiscence: partial opening of the wound, especially in the intergluteal area.
- Implant exposure: rare, but possible if the tissues thin.
When is hybrid butt augmentation the right choice?
El Supercharged BBL It is indicated when fat alone cannot provide the necessary projection. For example, it can be a good option for patients with little donor fat, flat or square buttocks, and a desire for a more structural change.
On the other hand, if the patient has sufficient fat and is seeking a moderate increase, a BBL with own fat That may be enough. Therefore, the choice depends on your anatomy, fat distribution, tissue quality, and desired outcome. To compare options, you can also read this guide on BBL with or without implants.

Frequently asked questions about biconvex buttock implants
What are biconvex buttock implants?
These implants are curved on both sides. They are designed to provide greater central projection, especially in patients with flat, square, or structurally weak buttocks.
Why were 370cc implants used in this case?
Because the patient needed significant central projection to transform a square silhouette into a more curvaceous figure. However, the size is always decided according to the anatomy, tissues, and aesthetic goal.
Do biconvex buttock implants cause capsular contracture?
Clinically significant capsular contracture is extremely rare in gluteal implants. Therefore, the most relevant risks are usually others, such as seroma, malposition, infection, or healing problems.
Is a BBL with fat transfer better than a hybrid butt lift?
It depends on the anatomy. If there is sufficient fat and the goal is moderate, a BBL may be sufficient. However, if there is a lack of structural projection or the patient has little fat, a hybrid augmentation may be more appropriate.
How long does the result last?
The implant is permanent. Furthermore, the transferred fat that survives the first few months tends to stabilize long-term. The final result is usually assessed between 3 and 6 months.
When can I get back to my routine?
Most patients can resume gentle activities within about two weeks. However, strenuous exercise is usually postponed for about six weeks, always according to individual medical advice.
