Paper by Dr. Keisuke Matsumura of TCB on Thread Lifts Published in International Academic Journal "European Journal of Plastic Surgery". Quantifying Efficacy and Retention Rate with a 3D Imaging Analysis System.

Dr. Keisuke Matsumura of TCB Tokyo Central Cosmetic Surgery (CEO: Hiroo Teranishi, hereinafter "TCB"), an aesthetic clinic with 102 branches nationwide (as of May 2026), conducted research on the efficacy and retention rate of thread lifts using a 3D imaging analysis system. He announced the publication of the paper titled "Upward vector observed in all 17 cases after non-absorbable polyester–silicone thread lift: a vectra 3-D pilot study" (3D Quantitative Evaluation of Non-Absorbable Thread Lift: A Pilot Study Using Vectra 3D). This study quantitatively evaluated the effect of thread lifts using non-absorbable polyester-silicone threads in terms of volume (mL) and assessed the retention rate, utilizing the Vectra H2® 3D imaging analysis system. The paper was published in May 2026 in the international academic journal "European Journal of Plastic Surgery." Paper: "Upward vector observed in all 17 cases after non-absorbable polyester–silicone thread lift: a vectra 3-D pilot study" Paper Title: Upward vector observed in all 17 cases after non-absorbable polyester–silicone thread lift: a vectra 3-D pilot study Journal: European Journal of Plastic Surgery Publication Date: May 2026 Authors: Keisuke Matsumura, Takahiko Tamura, Kohki Okumura, Hiroo Teranishi URL: https://rdcu.be/fgowN Background While non-absorbable thread lifts are theoretically expected to provide long-term support, objective evaluation based on volume (mL) using three-dimensional (3D) images has been limited. This study aimed to quantify the volumetric lift effect and retention rate of thread lifts using Vectra 3D analysis. Methods As a single-center prospective pilot study, 17 cases of thread lifts using non-absorbable polyester-silicone threads were subjected to Vectra H2® imaging at pre-operation (T0), 1 month post-operation (T1), and 3 months post-operation (T2). Two highly reproducible ROIs (Zone 1/Zone 2) based on landmarks were set, and the primary evaluation index ΔV was calculated. ROI setting and volume calculation were performed independently by two physicians, and the average values were used for analysis. Results ΔV at 1 month post-operation was positive in all cases, and the retention rate at 3 months post-operation was also evaluated. No thread removal due to infection was observed during the observation period. Conclusion In non-absorbable polyester-silicone thread lifts, the volumetric index ΔV using Vectra 3D objectively demonstrated the lift effect and retention rate. The highly reproducible ROI design and demonstration of inter-rater agreement showed the feasibility of implementing this as a quantitative evaluation framework.
