Effect of pdo facelift threads on facial skin tissues: An ultrasonographic analysis.

[BACKGROUND] Recent studies demonstrate that PDO threads, after being introduced into the facial skin, provide benefits due to collagen formation around the thread and improved vascularization.

[AIMS] This work aims to report the ultrasound and photographic follow-up after the execution of the facelift thread technique, thus evaluating the anti-aging treatment that PDO threads will provide for human facial skin.

[METHODS] The facelift will be performed using PDO thread 18G cannulated Sculpt i- Thread FML 100 × 185 mm, and 29G PDO thread Needled Flat i-Thread 38 × 50 mm. A total of 10 patients were selected for the study; all of them had medium-grade facial ptosis and aged 40-50 years old. In order to control tissue changes after thread, insertion ultrasound measurements will be made with Philips ultrasound 12 MHz linear probe at maximum resolution, initial evaluations and control of 30, 60, 90, and 120 days, measuring the skin layers: epidermis\dermis and hypodermis. Photographic control was performed before and after 120 days of intrusion of the PDO threads.

[RESULTS] The formation of collagen around the PDO thread was evidenced through ultrasound images in all patients in this study, as well as improvement in the appearance of the skin and sagging, evaluated by photographic control.

[CONCLUSIONS] We can define that the PDO threads used for the facelift are effective in the formation of collagen around the thread (observed through the increase in the dermal layer), and improvement of the condition of the anti-aging factor through sagging skin, vascularization and thinning of the superficial fat layer (observed through the reduction of the subcutaneous or hypodermis layer).
