Objective The goal is to optimize the diagnosis of complications after thread implantation using high-resolution ultrasound (US).Material and Methods The study design included the formation of twelve sample comparison groups. Inclusion criteria for the group: women without evident somatic pathology after cosmetic implantation in various periods after the procedure. The difference between the groups was in the chemical composition of the material (L-lactic acid, polydiaxanone, copolymer of L-actide with ԑ-caprolactone, polypropylene, polyester fiber in a silicone sheath, metal), complaints (the presence of amyctic, the presence of overcorrection, the absence of complaints), the period of time after implantation (up to 6 months, from 6 to 12 months, more than a year). Then ultrasound was performed, 33 qualitative and 7 quantitative indicators were analyzed. The study involved 93 women aged 29 to 65 years after the thread implantation. The circulation period varied from 3 days to 20 years.Results An analysis of the relationship between quantitative and qualitative features revealed statistically significant connections between the presence of an acoustic shadow and threads of polylactic acid and polypropylene, the presence of reverberation, and the metal – gold (p < 0.0001). Relationships were established between polyester fibers in a silicone sheath with complaints of inflammation, the presence of edema during examination, perifocal edema around the thread during ultrasound (p < 0.0001). The difference was also found between the diameter of the thread in the group of patients examined up to 6 months and the group in the period 6–12 months after implantation (p < 0.0001), as well as the group up to 6 months and more than a year (p = 0.0033).Conclusion The presence of an acoustic shadow, a thread diameter of more than 1 mm are ultrasound signs of fibrotic changes around the thread. The characteristic echographic signs of inflammation around the thread will be a zone of reduced echoicity, corresponding to perifocal edema. Hypercorrection is a consequence of fibrotic changes development around the thread.
