This review article discusses the fundamental principles and practical applications of facial and neck thread lifting procedures. The authors aim to clarify key concepts such as fixing point, hanging point, and anchoring point, as well as the vectors involved in thread lifting. They also provide anatomically oriented explanations of the lifting process for different facial regions using various thread techniques, including V, U, and I-shaped threads. The review emphasizes the importance of understanding tensile strength, anchoring strength, and holding strength, and how these factors influence the effectiveness of thread lifting. The article highlights the importance of considering the varying strength of facial retaining ligaments, as this can lead to differences in skin and tissue sagging across facial areas. The authors also explore the mechanisms of thread lifting, focusing on how specific types of threads can be used to address sagging tissues and improve different facial regions. They emphasize the need to differentiate between anchoring strength and holding strength, as well as the role of various thread designs in achieving long-lasting results. The review discusses different thread lifting techniques, including lateral facial lifting using I-type bidirectional cogged threads, U-type cogged threads, and V-type cogged threads. It also covers thread lifting for double chin improvement using long-length cannula-guided or double needle cogged threads. The authors emphasize the importance of tissue consistency and the role of thread placement in achieving effective results. The review concludes that thread lifting procedures have significantly improved in addressing facial sagging, particularly in the lateral face region. The authors stress the importance of considering the unique anatomical features of each patient and the need for a thorough understanding of the underlying principles of thread lifting to achieve optimal outcomes.This review article discusses the fundamental principles and practical applications of facial and neck thread lifting procedures.
