Facial thread lifting has emerged as a minimally invasive alternative to traditional face-lifting procedures, with particular emphasis on U-shaped and I-shaped barbed threads. This review analyzes the anatomical considerations, procedural techniques, and clinical outcomes of different thread types for facial rejuvenation. The study examines the mechanical principles and lifting mechanisms of U-shaped "suspension type" threads versus I-shaped threads, highlighting their distinct characteristics and applications. The results indicate that U-shaped threads provide strong lifting effects, with success rates reported at 85-90% in achieving visible tissue elevation when anchored in the temporal area. However, these threads carry higher risks of complications, including bleeding (15-20%), dimpling (12-18%), and tissue damage at exit points (5-10%). In contrast, I-shaped threads demonstrate advantages in minimizing tissue trauma and patient discomfort, with complication rates below 5%, though they may provide less dramatic lifting effects. The study concludes that optimal outcomes are achieved through careful patient selection and customized combination approaches rather than reliance on a single thread type. Future directions point toward the development of hybrid techniques that combine the strengths of both thread types to maximize efficacy while minimizing complications.
面部线雕已成为传统面部提升手术的一种微创替代方法，尤其强调U形和I形倒刺线。本综述分析了用于面部年轻化的不同线类型的解剖学考量、手术技术和临床结果。该研究考察了U形“悬吊型”线与I形线的力学原理和提升机制，突出了它们各自独特的特点和应用。结果表明，U形线具有强大的提升效果，当锚定于颞部区域时，实现可见组织提升的成功率报告为85 - 90%。然而，这些线的并发症风险更高，包括出血（15 - 20%）、酒窝形成（12 - 18%）以及出线点处的组织损伤（5 - 10%）。相比之下，I形线在使组织创伤和患者不适最小化方面表现出优势，并发症发生率低于5%，不过它们可能提供的提升效果没那么显著。该研究得出结论，通过仔细的患者选择和定制化的联合方法而非依赖单一的线类型可实现最佳效果。未来的方向指向开发结合两种线类型优势的混合技术，以在使并发症最小化的同时最大化疗效。
