Abstract

Background: Facial treatments with lifting threads are one of the non-surgical options increasingly requested in dermatology and plastic surgery offices. Despite, the practice techniques still lack systematization both to achieve more satisfactory results and to prevent adverse events. Most of the available publications provide little or no basis regarding the mechanics and physics of the aging process. Objective: In this study, we bring our experience of more than 4 years using PDO threads for repositioning ptosis of the facial subcutaneous tissues that occurs during the aging process, in a safe, reproducible and effective technique. All techniques employed are based on the physical, mechanical and biological characteristics of PDO threads, as well as the aging process and anatomical features of the human face. Materials and methods: Eighty-five patients underwent facial repositioning treatment with cog threads, whether barbed or molding. The threads used were USP 3-0 to 0-2 and were chosen according to each patient indication. Results: Most patients reported very satisfactory results, with minimal discomfort during the immediate post-treatment period. Among all treated patients, no cases of thread migration or breakage were observed, with only one instance of a pyogenic granuloma forming at one thread entry point. Conclusion: The vector technique with anchoring, using a knot posterior to the facial ligament line, for facial repositioning with PDO threads can be considered safe and effective for sagging treatment due to skin aging process. Technique is very predictable, with homogeneous results and fully reproducible by qualified professionals.
