Facial lifting with polydioxanone barbed threads has been widely used in aesthetic treatment for years. However, gravity resists the thread and continuously pulls the face downward. This study aims to determine methods to lift the skin more efficiently with longer longevity. The quality of the thread is important and is defined by the pulling and pullout strengths. Moreover, the method of using threads is also important. We compared five thread-implantation techniques and six angles for the V-shaped implantation methods using a polydimethylsiloxane model to simulate thread migration in tissues. The results of the simulated thread-lift techniques can provide valuable information for physicians, enabling a more precise design of facelift surgery techniques.
多年来，聚二氧六环倒刺线面部提升术已广泛应用于美容治疗。然而，重力会对抗缝线并持续向下拉扯面部。本研究旨在确定更有效地提升皮肤且维持时间更长的方法。缝线的质量很重要，由拉伸强度和拔出强度来定义。此外，缝线的使用方法也很重要。我们比较了五种缝线植入技术以及V形植入法的六个角度，使用聚二甲基硅氧烷模型来模拟缝线在组织中的迁移。模拟缝线提升技术的结果可为医生提供有价值的信息，从而更精确地设计面部提升手术技术。
