Expansion Vibration Lipofilling (EVL) is an advanced technique in fat grafting and body contouring, particularly in procedures such as the Brazilian Butt Lift (BBL). This innovative method enhances the traditional fat transfer process, aiming to improve safety, precision, and aesthetic outcomes. It was described by Dr Simeon Wall Jr who also described SafeLipo. We look at EVL and how it differentiates itself from conventional techniques:

 What is EVL?

EVL, or Expansion Vibration Lipofilling, is a technique developed to optimise the process of fat grafting. It combines two key elements:

1. Expansion: This involves using a specially designed cannula that creates an expanded space in the tissue where the fat will be injected. The expansion helps to make room for the fat cells, reducing pressure and potentially increasing the survival rate of the transplanted fat.

2. Vibration: The cannula is equipped with a vibrating mechanism. The vibration helps to gently and evenly distribute the fat into the targeted areas, promoting a smoother and more consistent result.

 How is EVL Performed?

The EVL procedure involves several steps:

1. Fat Harvesting: Similar to traditional fat transfer procedures, fat is first harvested from donor areas of the patient’s body using liposuction. Common donor areas include the abdomen, thighs, and flanks.

2. Fat Purification: The harvested fat is then purified to remove any impurities, excess fluids, and non-viable fat cells. This step ensures that only the healthiest fat cells are used for the transfer.

3. Expansion Phase: Using the specialized EVL cannula, the surgeon creates an expanded space within the tissue. This step helps to reduce pressure on the newly injected fat cells, potentially increasing their survival and integration into the tissue.

4. Vibration-Assisted Injection: The purified fat is then injected into the expanded space using the vibrating cannula. The vibration assists in evenly distributing the fat, which can lead to a more natural and smooth appearance. The device used is the MicroAire system.

 Benefits of EVL

EVL offers several advantages over traditional fat grafting techniques:

– Improved Fat Survival: The expansion phase reduces pressure on the fat cells, which can increase their survival rate and lead to longer-lasting results.

– Even Distribution: The vibrating cannula helps to distribute the fat more evenly, reducing the risk of lumps and irregularities.

– Enhanced Safety: By creating an expanded space for fat injection, EVL can reduce the risk of complications such as fat embolism.

– Natural Results: The technique promotes a smoother and more natural-looking contour, enhancing the overall aesthetic outcome.

 Why Choose EVL?

EVL is particularly beneficial for patients seeking:

– Enhanced Contouring: For those looking to achieve more defined and natural curves.

– Higher Fat Survival Rates: Patients who want long-lasting results from their fat transfer procedures.

– Reduced Risk: Individuals concerned about the potential complications associated with traditional fat grafting methods.

FAQs on EVL

How does EVL differ from traditional fat grafting techniques?

EVL uses a combination of tissue expansion and vibration-assisted fat injection, which can improve fat cell survival, enhance even distribution, and reduce the risk of complications.

Is EVL safe?

Yes, EVL is designed to enhance the safety of fat grafting procedures. The expansion phase reduces pressure on injected fat cells, and the vibration-assisted injection helps to avoid deep tissue injections that could lead to complications.

What procedures can benefit from EVL?

EVL can be used in various fat transfer procedures, including Brazilian Butt Lifts (BBL), breast augmentation, and facial fat grafting.

How long is the recovery period after an EVL procedure?

Recovery time is similar to traditional fat grafting procedures, typically ranging from 2 to 4 weeks. However, the specific timeline can vary depending on the extent of the procedure and the individual’s healing process.

Can EVL be combined with other body contouring procedures?

Yes, EVL can be effectively combined with other procedures such as liposuction, tummy tucks, and breast lifts to achieve comprehensive body contouring results.

What should I expect during a consultation for EVL?

During the consultation, your surgeon will assess your goals, evaluate your anatomy, and determine if EVL is the right technique for you. They will also explain the procedure, potential risks, and recovery process.

Conclusion

Expansion Vibration Lipofilling (EVL) represents a significant advancement in the field of fat grafting and body contouring. By combining tissue expansion with vibration-assisted fat injection, EVL enhances the safety, precision, and aesthetic outcomes of procedures like the Brazilian Butt Lift.
