Developed by dermatological surgeon Jeffrey Klein in the 1980s, tumescent liposuction changed the surgical removal of localized body fat. In this method, an anesthetic solution based on lidocaine and other products is diluted in saline and infiltrated in large quantities in the fatty layer of the skin. This causes local swelling, constricting blood vessels and decreasing bleeding and bruising. In addition to the use of local anesthesia and minor bleeding, the technique is notable for its low rate of serious complications.
Tumescent liposuction must be performed by a trained professional in a surgical environment. When the patient’s condition is good, it may be a non-hospital operating room. The procedure involves injecting large volumes of a solution directly into the areas of excessive fat deposition. After a small incision is made in the skin, microcannulas are inserted into the fat layer. They can be connected or not to a vacuum machine and with reciprocating movements, the fat is sucked through the tube to a sterile collection system, or in the case of manual liposuction, to the syringe. An elastic compression belt is used to aid in skin contraction and recovery. The result is a “sculpture” that transforms protruding areas into more attractive contours.
Tumescent liposuction has the benefit of reducing skin irregularities, causing less bleeding, less bruising and allowing faster recovery. It is most effective for removing deposits of localized fat that do not respond to exercise or diet, and is not intended to be a substitute for weight loss, but rather a procedure for defining contours.
By using local anesthesia, tumescent liposuction allows the removal of a maximum of two liters of fat per session, being an option indicated for patients who have localized fat, but are not obese.
Before undergoing tumescent liposuction, the patient must make a complete surgical risk assessment. It is necessary to take measurements of the areas to be treated and discuss the expectations regarding the procedure with the doctor, which need to be realistic.
The procedure takes about two and a half hours, and post-operative care requires attention. The duration of rest and the period for returning to daily activities vary from patient to patient, and the use of analgesics may be necessary. The patient must use a mesh mesh (brace) for one month after surgery – the doctor will indicate the most suitable model. You should avoid high physical effort for at least 15 days, and avoid exposure to the sun for approximately two months.
