Background: Thread lifting is one of the most common minimally invasive options in facial rejuvenation procedures. The application of polydioxanone (PDO) showed good results and fewer complications. PDO threads effectively strengthen the contour of the face, reduce roundness, and lift sagging skin due to collagen-stimulating properties.
Objective: The purpose of this study was an evaluation of the efficacy of the PDO threads: the combination of the cog type and press cog type threads (Ncog and Nfix) and cog type thread (Ncog) alone. And this study was conducted to define complications related to thread inserting during the follow-up period.
Materials and methods: Thirty patients who underwent PDO thread treatment for facial rejuvenation and tightening sagging skin tissues were evaluated. The follow-up period was seven months. Photographic objective and subjective evaluations were performed during this period.
Results: Thirty patients were included in this study. The mean age of participants was 51.8 years (range 65 to 34). There was a statistically significant difference between pre and 1-month post-operative results in both groups with a mean score of 1.94 ± 0.43 (p < 0.05). Furthermore, the combination of Ncog and N fix showed slightly better results than Ncog alone. According to patient satisfaction, all patients were satisfied with the clinical outcomes.
Conclusions: Our results revealed PDO threads are effective in aged skin rejuvenation, soft tissue retraction, and support, showing fewer complications. In addition, it could be assumed that treatment with thicker thread could be a more efficacious procedure. However, this statement requires further researches.
