The Understanding and Stability of Insertion Layers in Thread Lift

Thread lifting is popular for addressing the loss of facial skin elasticity and reducing wrinkles. However, the incidence of complications varies with the practitioner’s competence, the characteristics of materials used, and variations in procedural techniques. Therefore, this study aimed to compare the outcomes of thread lifting procedures based on the insertion layer and suture length to propose different techniques tailored to the objective of thread lifting. We assessed the major complications observed in individuals who underwent thread lifting to evaluate the overall efficacy and safety of the procedure. From March 2022 to January 2023, we performed thread lifting using Vxil threads with uni-and multi-layer insertion on 24 patients, and evaluated the outcomes and complications. The mean age of the patients was 37.5 (range 24-63) years, and the mean follow-up period was 199 (range 188-207) days. An average of 4.4 long lines (2-8 lines) and 12.6 middle lines (8-16 lines) were used. The degree of pulling after insertion varied with the technique and length of threads. For uni-layer insertions, a greater amount of tissue displacement was observed. Displacement was also greater using long lines than using middle lines. The global aesthetic improvement scale score increased, indicating increased satisfaction, at the 3-month and 6-month follow-ups. Reported complications included edema, pain, foreign body sensation, bruising, asymmetry, and temporary sinking. Clinicians need to choose the appropriate thread and procedure technique based on their research and efforts to minimize complications and boost patient satisfaction.
