The Brazilian Butt Lift (BBL) has become one of the most sought-after cosmetic surgery procedures worldwide. However, this procedure has long been associated with significant risks, particularly fat embolism, a potentially fatal complication. In response to these concerns, the SMART BBL (Safe Subcutaneous Buttock Augmentation) technique represents a major advancement in safety, particularly through the use of ultrasound.
What is SMART BBL?
SMART BBL is an innovative buttock fat grafting technique that prioritizes patient safety by using ultrasound as a guide throughout the entire procedure. This approach allows the surgeon to visualize the depth of fat injection in real-time, ensuring that it remains in the subcutaneous layer and never reaches the gluteus maximus muscle or deep blood vessels.
Fundamental Principles of SMART BBL
The technique is based on three essential pillars:
Exclusive subcutaneous injection: Fat is injected only in the tissue layer between the skin and muscle, avoiding any intramuscular penetration. This area is much safer as it contains fewer large-calibre blood vessels.
Continuous ultrasound guidance: Ultrasound allows the surgeon to see precisely where the injection cannula is located at all times. This real-time visualization eliminates guesswork and ensures optimal fat placement.
Standardized protocol: SMART BBL follows a strict and reproducible protocol, established by international plastic surgery experts, which standardizes practices and reduces technical variations that could compromise safety.
Why is Ultrasound Crucial?
The use of ultrasound during BBL represents a paradigm shift in this procedure. Before the introduction of this technology, surgeons had to rely solely on their tactile experience and external anatomical landmarks to estimate injection depth.
Benefits of Ultrasound
Real-time visualization: The surgeon sees the cannula progressing through the tissues and can instantly adjust its trajectory if necessary. This direct visual control capability transforms a procedure once performed blindly into a precise and controlled intervention.
Identification of at-risk structures: Ultrasound allows important blood vessels to be identified and avoided with precision. The inferior and superior gluteal veins, primarily responsible for fatal fat embolisms, become visible and can be circumvented.
Depth verification: At any time, the surgeon can confirm that fat is being injected at the correct anatomical level, in the superficial or deep subcutaneous zone, but always above the muscular fascia.
Objective documentation: Ultrasound images can be recorded, providing traceability of the procedure and allowing for subsequent analysis if necessary.
The SMART BBL Procedure
Preoperative Phase
Before the procedure, a thorough consultation is conducted to assess the patient’s anatomy, expectations, and compatibility with the procedure. A preliminary ultrasound examination allows mapping of each patient’s vascular and muscular anatomy, as this varies from person to person.
The Procedure Itself
Liposuction: The first step involves harvesting fat from donor areas (abdomen, flanks, thighs, back). This fat is collected using gentle techniques to preserve the viability of fat cells.
Fat purification: The harvested adipose tissue is processed to remove impurities, blood, and fluids, retaining only adipocytes of optimal quality.
Ultrasound-guided injection: The surgeon injects the purified fat into the buttocks while following the cannula’s path on the ultrasound screen. Each pass is visualized to ensure exclusive subcutaneous placement. Fat is deposited in thin layers to promote vascularization and cell survival.
Final verification: A complete ultrasound is performed at the end of the procedure to ensure homogeneous fat distribution and the absence of immediate complications.
Postoperative Period
Recovery following SMART BBL is similar to that of traditional BBL, but with potentially fewer complications. Patients must avoid sitting directly on their buttocks for approximately two weeks, use a special BBL cushion, wear compression garments on liposuction areas, and follow a progressive recovery protocol.
Reduced Risks with SMART BBL
Fat Embolism: A Risk Nearly Eliminated
Fat embolism occurs when injected fat enters the deep gluteal veins, located in or beneath the gluteus maximus muscle. These fat particles can then migrate to the lungs, causing a potentially fatal pulmonary embolism.
With SMART BBL and ultrasound guidance, this risk is significantly reduced because the surgeon ensures that the cannula never crosses the muscular fascia barrier. Clinical studies show a drastic decrease in serious complications with this approach.
Other Minimized Complications
Asymmetry: Ultrasound visualization allows for more uniform fat distribution, reducing asymmetry risks.
Fat necrosis: By injecting fat in thin layers and at the correct level, graft vascularization is optimized, improving their survival.
Infection: The standardized protocol and less traumatic technique reduce infection risks.
Expected Results and Durability
SMART BBL offers natural and harmonious results. Although the injection is subcutaneous rather than intramuscular, patients achieve satisfactory volume enhancement with improved buttock contour.
Fat Survival Rate
Approximately 60 to 70% of injected fat survives permanently. Final volume generally stabilizes three to six months after the procedure. This partial resorption is normal and anticipated during surgical planning.
Natural Appearance
Unlike buttock implants, SMART BBL uses the patient’s own tissues, ensuring a naturally-feeling result and harmonious appearance that evolves naturally with the body.
Who is a Candidate for SMART BBL?
Ideal candidates for this procedure are individuals in good general health, with sufficient fat reserves for harvesting, with realistic expectations regarding results, non-smokers or willing to stop smoking several weeks before and after the procedure, and at a stable weight.
It’s important to note that BBL, even with the SMART technique, is not a weight loss solution but a body contouring procedure.
Choosing Your Surgeon
The safety of SMART BBL depends greatly on the surgeon’s expertise. It’s essential to choose a certified plastic surgeon, specifically trained in the SMART BBL technique, experienced in using ultrasound in cosmetic surgery, member of recognized professional associations, and with a certified operating theatre.
Don’t hesitate to ask to see before/after photos of patients who have undergone the SMART BBL technique, and to ask all your questions during the consultation.

Frequently Asked Questions (FAQ)
1. Is SMART BBL more expensive than traditional BBL?
SMART BBL may cost slightly more due to the necessary ultrasound equipment and surgeon’s specialized training. However, this additional cost is justified by the significant increase in safety. Prices generally range from $8,000 to $16,000 CAD depending on countries and surgeons, liposuction areas, and volume of fat to be transferred.
2. Does using ultrasound make the procedure longer?
Ultrasound may add 30 to 45 minutes to the total procedure time, but this additional time is minimal compared to the safety gain. Most SMART BBL procedures last between 3 and 4 hours total.
3. Are SMART BBL results different from traditional BBL?
Aesthetic results are comparable, if not superior, as fat distribution is more controlled and uniform. The main difference lies in the increased safety of the procedure, not in the final outcome.
4. How long is recovery after SMART BBL?
Initial recovery takes approximately 2 to 3 weeks, during which direct sitting on the buttocks must be avoided. Return to normal physical activity may take 6 to 8 weeks. Final results are visible after 3 to 6 months.
5. Can SMART BBL be combined with other procedures?
Yes, SMART BBL is often combined with other procedures such as abdominoplasty, extended liposuction, or breast augmentation. However, your surgeon will assess whether this combination is safe in your particular case.
6. Are there scars after SMART BBL?
The incisions needed for liposuction and fat injection are very small (a few millimetres). Scars are generally minimal and discreet, placed in inconspicuous areas.
7. How much fat can be injected during SMART BBL?
Volume depends on several factors: the amount of fat available in donor areas, the patient’s buttock anatomy, and safety limits. On average, 400 to 800 ml of purified fat is injected per buttock, knowing that 60 to 70% will survive permanently.
8. Is SMART BBL painful?
Postoperative pain is mainly related to liposuction areas rather than the buttocks themselves. It’s generally well controlled by prescribed pain relievers. Most patients describe a sensation of significant soreness rather than acute pain.
9. Can all surgeons perform SMART BBL?
No, SMART BBL requires specific training in ultrasound use in cosmetic surgery. Ensure your surgeon has completed this training and regularly practices this technique.
10. What happens if I gain or lose weight after SMART BBL?
Transferred fat cells behave like other fat cells in your body. If you gain weight, your buttocks may increase in volume; if you lose weight, they may decrease. Maintaining a stable weight is recommended to preserve results.
