Abstract

Aging is part of the human being, and the search for treatments to alleviate facial wrinkles is frequent in the dermatological office, where minimally invasive facial rejuvenation techniques often associate technologies and polydioxanone (PDO) threads that together present satisfactory result. The concern of most medical professionals when using these technologies, which initially heat the skin, is the possibility of breaking or melting the wires. However, it is well established that the melting point of PDO polymer is 110° to 115° C, a temperature well above the maximum temperature reached by thermal damage to tissues caused by technologies. Although there are still no publications on protocols and technologies for associating PDO threads, however, through the scientific evidence already well established by the basic principles of the technologies and their mechanisms of action, interaction with the tissue, it is possible to associate these techniques. A summary of the associations of the most common current technologies with PDO threads can be found in Table 1. Among the technologies, microfocused ultrasound (HIFU) acts in the same anatomical plane as the PDO threads, which is the superficial subcutaneous layer. For contextualization, I report the case of a patient where HIFU and PDO wires with claws were performed and the result after 60 days. 150 shots were performed per hemiface with Ultraformer® technology with the tips: 4.5 - 30 shots 0.8 mj; 3.0 - 30 shots, 0.7 mj; 2.0 - 50 shots 0.3 mj and 1.5 0.2 mj 40 shots. Then, 2 PDO Sculpt® wires 18 G x 165 mm were made in the middle third and 2 PDO spiculated wires 19 G x 160 mm in the lower third per hemiface, totaling 8 (Figure 1). This poster aims to bring clarity on how to use the technology associated with PDO threads.
