Minimally invasive combined technique of thread implantation, including the use of lifting threads from polydioxanone and a copolymer of polylactic acid and polycaprolactone and reinforcing threads from 100% polylactic acid

Abstract

Modern scientific studies demonstrate a direct relationship between a decrease in the quantitative ratio of type I/III collagen in tissues and the severity of age-related changes, the formation of a deformative type of aging and the early development of ptosis of the lower third of the face able to compensate for the reduced ratio of type I/III collagen. In addition, the specificity of the threads used to perform lifting technologies provides an increase in collagen, predominantly of type III, and a relatively small number of them and only a certain lifting route are used. Currently, the clinical efficacy of 100% polylactic acid threads has been proven, which are able to stimulate the synthesis of type I collagen. Thus, the combination of lifting and reinforcing techniques in one procedure is expedient and relevant.
 In order to achieve aesthetic and lifting results of thread techniques, as well as to increase the intensity of microcirculation, oxygenation and stimulation of collagenogenesis (including type I), we have developed a method of minimally invasive combined technique of thread implantation, including the use of lifting threads made of polydioxanone and polylactic acid copolymer and polycaprolactone and 100% polylactic acid reinforcing threads.
 The minimally invasive technology provides prolongation of the lifting effect; creates the effect of volumization of facial tissues and the supporting dynamic framework in conditions of tissue displacement, and also improves the quality of skin structures by stimulating trophic and oxygenation of tissues, strengthening the collagen framework, increasing the ratio of type I/III collagen, enhancing the production of its own hyaluronic acid and extracellular matrix components.
