Most patients do not need the most popular surgery

How to choose the right buttock surgery?

By Dr. Alexander Aslani, MD — Cirumed Clinic, Marbella | Collaborating member of the ASERF Task Force on Gluteal Fat Grafting Safety

Most patients arrive for their consultation thinking they already know what surgery they want. Many believe they need a BBL Because it's the most well-known procedure. Others arrive convinced they need implants because they want more projection. Some ask about fillers because they want to avoid surgery. But when it comes to buttocks, the most important question isn't which procedure sounds better, but which surgery is really right for your anatomy.

That's where a specialist consultation completely changes the logic of the case. The right surgery isn't chosen based on preference, trends, or an image seen on social media. It's chosen according to the available donor fat, the baseline projection, the waist-to-hip ratio, tissue quality, and the result that can be achieved safely and with long-term stability.

The right surgery

One of the most frequent mistakes in buttock augmentation is starting with the technique instead of starting with the body. When a patient comes in asking for a BBLThat request doesn't guarantee that a BBL is the best solution. Similarly, wanting more projection doesn't automatically mean you need implants. And seeking a non-surgical alternative doesn't make fillers an equivalent option.

What separates a well-indicated buttock surgery from a poorly planned one is a simple question: What can this anatomy achieve safely and stably?

In some patients, the donor fat is excellent and the real priority is contouring. In others, the underlying gluteal structure is so flat or the fat so scant that fat transfer alone cannot solve the problem. In still others, the best result will come not from choosing between BBL or implants, but from combining both in a hybrid strategy such as the Supercharged BBLThat is the true core of the surgical decision.

The 3 key questions

Before recommending any technique, an experienced buttock surgeon needs to answer three essential anatomical questions:

• How much viable donor fat is available and where is it distributed?
• Does your anatomy need volume, does it need structure, or does it need both?
• What is your current waist-to-hip ratio and how much can it realistically be improved?

These three questions are more important than the initial preference for a procedure. A patient with very little donor fat will not achieve great results with a BBL, even if that was her first idea. A patient with very flat buttocks and a need for architectural correction may require implants from the outset. And a patient with some fat, but who needs both structural projection and contour smoothness, may benefit more from a hybrid approach.

That's why, when a patient asks, "What kind of buttock augmentation do I need?", the correct answer doesn't begin with the name of the technique. It begins with anatomical analysis. That same principle underlies more advanced approaches such as the Supercharged BBLwhere not only the volume matters, but how it is distributed and how it is balanced with the existing anatomy.

When is a BBL better?

El BBL It is usually the best choice when the patient has sufficient donor fat, a reasonable anatomical base, and a goal of improving contour and proportion rather than an extreme structural need. In these patients, fat grafting can increase projection, round out contours, and improve the waist-to-hip ratio very naturally.

But even within the BBL, the outcome doesn't depend solely on how much fat is injected. It depends on how it's extracted, how it's processed, the injection rate, and the placement plane. The literature reports very wide fat survival rates, ranging from approximately 40 to 80 percent, and this variability isn't accidental. It's directly related to technical decisions.

Fat cells that are extracted with too much pressure, manipulated aggressively, or injected too quickly suffer more mechanical damage and have a lower survival rate. Furthermore, the visual outcome of a BBL depends not only on the buttocks but also on work done on the waist and flanks. When the surgery is approached as a comprehensive contouring procedure rather than simply a "buttock augmentation," the result is usually much more harmonious. This explains why more advanced techniques such as the Supercharged BBL have gained so much relevance in well-selected patients.

BBL Security

The safety of BBL changed decisively when the mechanism of fat embolism was better understood. Internationally reported cases of mortality led to a complete revision of practice standards. Today, the current consensus states that fat should be injected exclusively into the subcutaneous plane above the muscle, with the use of ultrasound strongly recommended.

This means that, if a patient is evaluating a BBLIt's not enough to ask how many a surgeon performs. You must also ask how He performs them. Does he use ultrasound guidance? Does he follow ASERF recommendations regarding the injection plane? Does he treat liposuction of the waist and flanks as an integral part of the result?

The right surgery shouldn't just be effective. It must be performed within an appropriate safety framework. That's one of the reasons why modern buttock augmentation shouldn't be evaluated solely on before-and-after results, but also on the technical process behind it.

When are implants best?

The gluteal implants They are often the best option when the patient has very little donor fat, a very flat gluteal anatomy, or a need for projection that fat alone cannot reliably achieve. In these patients, attempting a BBL first and then revising it with implants is usually a longer, more expensive, and more difficult process than choosing correctly from the start.

The great advantage of implants is that they offer immediate and lasting structural enhancement. But that doesn't mean that any implant, in any plane, and in any patient will work well. With buttock implants, the material, size, and especially the patient's budget are extremely important.

Therefore, for many thin patients or those needing architectural correction, the right question isn't "Can I get a BBL?", but rather "Can my anatomy achieve the desired result with fat transfer alone?". If the answer is no, implants cease to be a second option and become the correct structural solution.

The implant plan

One of the biggest misconceptions about buttock implants is that size is the only key factor. In reality, the most important technical decision is in what anatomical plane The implant is placed. A well-positioned implant in the correct plane performs better than a larger one placed in a less favorable plane.

The classic fully intramuscular placement offers good coverage, but subjects the implant to the full contractile force of the gluteus maximus. Over time, this can lead to displacement, discomfort, and asymmetry. The technique dual-planeDeveloped by Dr. Aslani in collaboration with Del Vecchio, Bravo, Zholtikov, and Palhazi, this technique distributes the pocket between a superior submuscular component and a inferior subfascial component. This reduces muscle load, improves definition of the lower pole, and promotes more natural transitions.

In other words, in gluteal implant surgery, the pocket is not a minor technical detail. It is one of the factors that most influences coverage, mechanical behavior, and the stability of the result. This structural logic is precisely what differentiates an architectural approach from a merely volumetric one.

When is hybrid technology better?

For patients who need structural projection but also have some donor fat available, the hybrid technique It usually offers the most comprehensive result. Here, the implants provide the architectural core, and the fat is used to smooth transitions, improve soft tissue coverage, refine hips, and round out the contour in a way that implants alone cannot achieve.

This hybrid approach is especially valuable in patients who need more projection than fat alone can provide, but who also want to avoid the stiff look, abrupt transitions, or overly mechanical contouring that can occur when everything depends on the implant.

From a surgical standpoint, this strategy is not simply a "sum of techniques." It's a way of better distributing functions: the implant addresses the structure, while the fat grafting addresses the integration of the result. Often, this intelligent distribution yields better results than overusing a single technique. This is also the principle behind more advanced concepts such as... Supercharged BBLwhere the distribution of volume matters as much as the quantity.

the fillings

Many patients inquire about fillers because they want to avoid surgery. But it's essential to understand an important difference: permanent fillers, such as silicone oil or PMMA, have a very serious and well-documented complication profile in the buttocks. Chronic inflammation, tissue destruction, material migration, and complex reconstructions are known risks.

Temporary hyaluronic acid fillers are another category and can have a limited role as an adjunct in a highly specialized surgical setting, for example, to correct minor irregularities or improve coverage in specific cases. But they are not a true substitute for surgery. BBL nor of implants when the patient wants a significant and lasting change.

The gluteal region requires large volumes for the change to be visible and withstands a very high mechanical load. Therefore, fillers are not the primary treatment option for most healthy patients seeking a genuine gluteal augmentation.

---

Which technique fits best?

Although each patient requires an individual assessment, this general logic is usually helpful:

• Good donor fat + primary need for contour and proportion: BBL
• Little donor fat + very flat buttocks + need for structure: implants
• Need for structure + some available fat for refining: hybrid technique
• Desire for significant change without surgery: Understand that fillers have limits and are not equivalent to a true buttock augmentation.

The key is not to fit all patients into the same option, but to understand that each technique addresses a different anatomical problem. That is the true basis of a well-indicated gluteal surgery. This type of reasoning also explains why articles like the one on Supercharged BBL They are so useful for understanding the real evolution of modern buttock augmentation.

What to ask the surgeon

Choosing the right technique matters, but choosing the right surgeon matters even more. When a patient is considering buttock augmentation surgery, there are several questions worth asking:

• Do you use ultrasound guidance and follow current safety recommendations for BBL?
• Do you have real experience with gluteal implants and dual-plane or subfascial techniques?
• Do you use hybrid techniques when the anatomy justifies it?
• Do you have published results or demonstrable experience in specialized gluteal surgery?

Scientific evidence is now robust enough to show that surgical experience, subspecialization, anatomical planning, and adherence to safety standards make a real difference in outcomes and complications. It may also be helpful to review other blog posts on advanced gluteal surgery to better understand how a specialist reasons when faced with a specific patient.

Conclusion

The real mistake in buttock augmentation isn't choosing a BBL, implants, or a hybrid technique. The real mistake is choosing a technique that doesn't suit the patient's anatomy. That's the root of many mediocre results, unnecessary revisions, and misguided expectations.

When the decision is well made, each technique has its place. BBL It's excellent for patients with sufficient fat and a need for natural contouring. Implants are a powerful tool when fat is lacking or real structure is needed. The hybrid technique is usually superior when a patient needs both projection and refinement. And fillers have only a very limited role, far from competing with true gluteal surgery.

The right way to choose is not to ask which procedure sounds best, but which one can offer the best result for your specific anatomy, safely and with long-term stability. That is precisely the change in mindset that also articulates concepts such as Supercharged BBLwhere the technique adapts to the anatomy and not the other way around.
