Wedge-shaped polydioxanone threads in a folded configuration ('Solid fillers'): A treatment option for deep static wrinkles on the upper face

摘要

Background Facial wrinkles are key signs of aging which affect one's quality of life and psychological well-being. Absorbable wedge-shaped polydioxanone (PDO) sutures are popular in the esthetic clinics of Korea and may be a treatment option for static wrinkles on the upper face. Objective To describe a novel technique applicable to deep static wrinkles on the upper face and to assess its safety and efficacy. Patients and Methods A retrospective chart review was performed on the static wrinkle cases which were treated with folded, wedge-shaped PDO threads. A total of 33 Korean patients with glabellar and forehead wrinkles were included. All participants underwent a single treatment session. The results were assessed objectively using serial photography and subjectively based on the patients' satisfaction scores. Complications were also recorded. Results Our patients displayed moderate (15.2%), severe (39.4%), and very severe (45.4%) static wrinkles at baseline. The majority of patients (81.8%) considered the results satisfactory. Consensus ratings by two independent dermatologists showed that the objective outcomes at 2-month follow-up were very much improved (30.3%), much improved (30.3%), and improved (24.2%). The incidence of complications was low, and the complications were minor. Conclusion Wedge-shaped PDO sutures in a folded configuration ("solid fillers") are a promising treatment option for deep static wrinkles on the upper face. They may be applied as an adjunct, or as an alternative to conventional therapies such as botulinum toxin and soft tissue filler injection.
