AESTHETIC RESULTS, SATISFACTION, AND PAIN ASSESSMENT WITH SMOOTH PDO (POLYDIOXANONE) THREADS: CASE SERIES

Abstract

The technique of smooth polydioxanone (PDO) threads has gained prominence as a minimally invasive option for facial rejuvenation, promoting collagen biostimulation and enhancing facial contouring. This study aimed to describe a series of cases and the aesthetic results, patient satisfaction, and pain associated with the use of smooth PDO threads of different thicknesses and vectors. Five clinical cases of female patients, aged between 40 and 58 years, who underwent treatment at a specialized clinic, were analyzed. The technique used varied according to the treated area, with the threads applied in strategic vectors to maximize lifting and support effects. Patient satisfaction was assessed using the Likert Scale, and pain was measured with the Visual Analog Scale (VAS). The results indicated that all patients showed noticeable improvement in facial appearance, with high satisfaction levels (Likert Scale = 5) and pain ranging from mild to moderate (VAS from 2 to 5). Complications were minimal, and pre- and post-procedure photos highlighted the observed improvements. It is concluded that the smooth PDO thread technique is an effective and safe alternative for facial rejuvenation, with a high patient satisfaction rate and a low incidence of complications. Future studies with larger samples are recommended to confirm the findings.
