Double-Layer Cogged Thread Lifting Technique: A Superficial- and Deep-Layer Lifting Method.

Abstract

Although thread lifting is a widely performed method, the degree of initial lifting and sustainability varies based on how the threads are inserted into the skin layers. This study aimed to perform thread lifting on 43 patients to achieve maximum lifting effects using thicker threads in the deeper layers of the subcutaneous fat layer and thinner threads in the shallower layers. Immediately after the procedure, we measured the depth of the inserted threads using ultrasonography and evaluated the results based on patient satisfaction and the global aesthetic improvement scale (GAIS). At the end of the procedure, an upright position was employed to check for dimples or irregularities, and intraoral observation was also conducted. Patient satisfaction significantly increased immediately after the procedure compared to that before the procedure. High GAIS scores were maintained even after 6months, indicating high satisfaction with the procedure. Inserting threads into multiple layers was deemed more effective than inserting them into a single layer. Thread lifting on 43 patients was used to maximize lifting effects by utilizing thicker threads in deeper subcutaneous fat layers and thinner threads in shallower ones. Our procedure maintained high global aesthetic improvement scale (GAIS) scores even after 6months, indicating patient satisfaction. Multiple layers were shown to be more effective than a single layer for thread insertion. This journal requires that authors assign a level of evidence to each article.
