A study proposes new standards for the safe execution of the Brazilian Butt Lift
A new anatomical study highlights critical technical problems to guarantee the safe performance of the “ Brazilian facelift ” more and more popular. A procedure using the patient’s fat to increase and improve the appearance of the buttocks. The study appeared in the official medical journal of the American Society of Plastic Surgeons (ASPS).
“ The study confirms that the gluteal fat transplant is safe, only if the injections remain in the tissue under -cutaneous “, said Daniel Del Vecchio, MD, plastic surgeon in Boston who developed the protocol and is a global expert on leading in this area. The comment of the co-author Rod J. Rohrich, MD , of the Dallas Plastic Surgery Institute, insists on the need to avoid any injection of fat in the gluteal muscle itself in order to prevent serious complications .
New evidence on the safe injection technique for gluteal fat transplantation.
Fat grafting has become a popular buttock enhancement technique for patients who want a smoother appearance curved and smoother, without using implants. In this procedure, the fat obtained by liposuction of a part of the body (such as the abdomen) is treated and injected to improve the gluteal region. According to ASPS statistics, more than 24,000 buttock increases with fat transplant were performed in 2018, , an increase of 19% compared to the previous year .
However, the serious complications resulting from this procedure are causing increasing concern. A 2015 article on plastic and reconstructive surgery reported a series of 22 deaths in patients undergoing injection of gluteal fat in Colombia and Mexico. The deaths were caused by pulmonary embolism: fatty deposits blocking the arteries of the lungs.
In 2018, the ASPS teamed up with other companies specializing in plastic surgery to issue an urgent warning concerning the number “ alarming ”of deaths linked to the increase in gluteal fat. A notice has been issued to plastic surgeons so that fat is only injected under the skin, never into the muscle.
To form the evidence base for this recommendation, Drs. Del Vecchio and Rohrich and their colleagues conducted a study on corpses to assess the patterns of fat spread in the gluteal region after injection. Four approaches were evaluated, simulating injection techniques that can be used by plastic surgeons performing gluteal fat grafting.
In three of the four injection techniques, the spread of simulated fat was mainly limited to the subcutaneous area, immediately under the skin. Even when small perforations were made in the aponeurosis, the layer of connective tissue separating the muscle from the subcutaneous space, the simulated fat had not spread very little or very little in the muscle itself.
Even with multiple perforations and high injection pressures, the muscle fascia prevented simulated fat from passing through the muscle. Researchers discuss the process of “ subcutaneous migration ” which prevents the injected fat from spreading into or under the gluteal muscle, if injected into the “ security zone ” subcutaneously.
The results were different in the fourth scenario, where several punctures were performed in the gluteal muscle. In this situation, large amounts of indirect fat were found under the muscle, which demonstrates that there was “ deep intramuscular migration “. Once fat has migrated into the submuscular space, damage to the veins in this area could allow fat cells to enter the circulation, with a potential risk for pulmonary embolism.
The experimental study provides important evidence in support of previous recommendations to ensure the safety of the Brazilian calf uplift. The researchers conclude: “ These convincing results are deep enough to suggest a new standard of care: no sub-fascial or intramuscular injection should be given and all injections should be made exclusively in the tissue subcutaneous. “
In his commentary, Dr Rohrich added: “If you are planning a glute augmentation procedure, please do so safely .”
