Abstract

Background/Objectives

Skin rejuvenation with laser is effective method to manage the skin aging process, however, it need repetitive procedures within short period. To compensate this shortcoming of laser, thread for facial tissue fixation is an excellent alternative of laser in skin rejuvenation. In this study, we evaluated the effectiveness of cogged polydioxanone(PDO) thread in improvement the lower face line and jowl.

Methods/Statistical analysis

A total of 55 consecutive patients with mild to moderate wrinkles were enrolled in the study. They underwent facial lifting with cogged thread (Secret Cog®, HyundaeMeditech, Korea) to correct lower facial line. Follow-up assessments were performed at 1 week, 4weeks and 3 months after procedure. The efficacy was rated by the two independent plastic surgeons using the Wrinkle Severity Rating Scale and patients’ satisfaction was assessed using the Visual Analog Scale. Post-operative complications were also recorded.

Findings

The patients showed prominent improvements after the procedure. The numbers of patient, presented WSRS difference greater than 1 were 53 (96.4%) on the left cheek and 54 (98.2%) on the right cheek. All patients achieved symmetrical facial state at all three post-operative visits. The mean satisfaction score of the patients was 6.6±2.6 on week 12. It also improved asymmetrical facial wrinkles.

Improvements/Applications
