PREVENTION OF AFTER LIPOSUCTION SOFT TISSUE DEFECTS BY STEM CELL TRANSPLANTATION

Abstract

The article provides information on the research work carried out to determine the improvement in aesthetic results by eliminating the complications that may occur after liposuction, significantly decreasing the level of soft tissue defects by using stem cells. Seventy patients underwent autologous fat grafting to prevent skin irregularities along with liposuction of the anterior abdominal wall. Patients divided into 2 groups: 1st group (30 patients), after liposuction, it was distributed in the form of fat, and in the 2nd group (40 patients), it was injected into the subcutaneous tissue in a form enriched with stem cells. Patients were observed for 6 months and evaluated on a 3-point scale (1 - insufficient, 2 - sufficient, 3 - excellent). Compared with autolipofilling, stem cell lipofilling reduced the volume of seromas and occurred in fewer patients. Fibrous secretions in the subcutaneous fat decreased, as a result, soft tissue defects were formed less frequently and weaker. Collagen and elastin fibers increased in the 2nd group, which made it possible to restore the softness and elasticity of the skin to a greater extent. Increased vascular proliferation improved skin nutrition. In the 2nd group, soft tissue defects and the need for corrections significantly decreased compared to the 1st group. This study showed that transplantation of autologous adipose tissue enriched with stem cells has a positive clinical effect.
