The EVL Difference

Developed by Dr. Simeon Wall Jr. as a logical extension of SAFELipo, expansion vibration lipofilling (EVL) is a surgical strategy that has revolutionized liposuction and fat grafting procedures by offering superior precision, efficacy, and safety. Using existing technology in an innovative way, plastic surgeons worldwide are adopting EVL as the new standard for body contouring.

Precise Contour Sculpting

Traditional fat transfer techniques produce unpredictable results due to the surgeon’s limited ability to truly shape the recipient area. EVL represents a paradigm shift in fat grafting procedures because it addresses this limitation with a combination of technology and technique. Instead of injecting fat with a syringe, the surgeon uses a vibrating, exploded-tip cannula to create space just below the skin and above the muscle, and simultaneously propel fat into the recipient areas.

This syringe-free approach enables surgeons to place the fat with a precision not possible using other fat transfer techniques. It also greatly enhances the volume of fat that can be transferred and remain viable.

The exploded portion of the cannula, typically twice the diameter of a typical 4-mm cannula creates 4 times more space as it moves through the treatment area. Additionally, the vibration significantly enhances the grafting procedure because the movement magnifies the impact of the cannula’s exploded “wings.”

Unlike fat injection, EVL distributes the fat evenly along the fascia, which acts as a barrier to prevent the formation of adhesions from the skin to the muscle. These adhesions cause contour deformities common after liposuction using other techniques.

Enhanced Safety

Surgeons adopted EVL as the standard of care for fat grafting buttock augmentation to avoid the safety issues associated with traditional Brazilian butt lift (BBL) techniques revealed in a 2015 study. In addition to prolonged surgical times associated with traditional BBL, there is a significant risk of fat embolism. Fat embolisms occur when fat is injected into a vein in the gluteus maximus muscle then travels to the lungs. The high risk of pulmonary fat embolisms in BBL patients drops to virtually zero when board-certified plastic surgeons use EVL for these procedures. A research paper co-authored by Dr. Wall Jr. documenting the enhanced safety of EVL for butt lift surgery—more accurately called “Safe Subcutaneous Buttock Augmentation”—was named Best Paper for 2018 by Plastic and Reconstructive Surgery Journal. The publication is the world’s largest and most prestigious plastic surgery journal, and one of the most respected journals in all of surgery.
