This article presents a study on the SMAS repositioning technique using cog threads, focusing on anatomical perspectives. The study highlights the importance of understanding dynamic changes in facial anatomy during postural shifts. Fresh cadaver studies show that threads can pass through the superficial musculoaponeurotic system (SMAS) layer, confirming the technique's efficacy. Proper insertion depth targeting SMAS repositioning is crucial, rather than superficial skin layers. The natural movement of tissues secured by thread insertion results in lifting effects. However, complications may arise if threads affect deeper facial muscles, leading to discomfort. Fibrous septa play a significant role in guiding thread placement, with different densities influencing thread maneuverability and tissue response during lifting. The conclusion emphasizes that procedures targeting SMAS repositioning using threads aim to maintain the new position of relocated tissues. Understanding structural variations in facial regions informs thread selection and placement. Aligning threads with tissue movement and the intended SMAS layer positioning is vital to prevent complications. Balancing thread insertion depth and tissue traction is critical for successful outcomes. The study discusses the anatomical basis of the SMAS repositioning technique, including the role of fibrous septa and the "moving plane" beneath the SMAS layer. It also explores clinical applications, such as positioning the patient on a tilting table to facilitate SMAS and reticular cutis concentration toward the temple before thread insertion. Another approach involves manually pushing the tissue toward the temple on the skin surface before inserting the threads. The discussion highlights the importance of proper thread insertion depth and the role of the SMAS layer in achieving natural lifting effects. It also addresses potential complications, such as threads penetrating the SMAS layer or causing discomfort. The study concludes that the contemporary concept of thread lifting focuses on the natural repositioning of deeper tissue layers such as the SMAS and its surrounding tissues, rather than forced lifting of superficial skin and subcutaneous tissue. The study also discusses the use of various thread types and the importance of considering factors such as the thickness and weight of the patient's skin and tissues, the extent of sagging, depth of wrinkles, and the patient's preferences.This article presents a study on the SMAS repositioning technique using cog threads, focusing on anatomical perspectives.
