Objectives: Nasolabial folds are a common concern across all ages and ethnicities. Causes vary, but in Asian women in their 20s–30s, including Japan, excess nasolabial fat—above the folds—is often a key factor. This study evaluates nasolabial fat liposuction with a thread lift, a procedure that removes fat and prevents sagging for facial rejuvenation. We assessed cases treated at our clinic using 3D imaging analysis and patient surveys to determine the efficacy of this combined approach. Introduction: Nasolabial folds result from age-related factors such as skin laxity, fat redistribution, and skeletal changes, making them a prevalent aesthetic concern. Various treatment modalities, including dermal fillers, liposuction, and thread lifts, have been explored, each with inherent limitations. This study investigates the synergistic benefits of combining nasolabial fat liposuction with a thread lift to achieve optimal facial rejuvenation outcomes. Materials / method: This study included 21 patients, aged 20 to 50, who underwent combined nasolabial fat liposuction and thread lift. The procedure was performed under intravenous anesthesia using microcannula liposuction, followed by the insertion of polydioxanone (PDO) threads along the nasolabial folds and midface region. Treatment outcomes were assessed through visual analysis (before-and-after photo comparisons), volumetric changes in the nasolabial fat area (measured via specialized equipment), and patient satisfaction surveys, including FACE-Q assessments andｘ. Results: The combined treatment significantly reduced the depth and visibility of nasolabial folds. At the three-month follow-up, objective 3D imaging (Life Viz®️) demonstrated an average reduction of 0.50cc in nasolabial fat volume. The FACE-Q assessment for "nasolabial fold depth (bare face)" yielded an average score of 3.29, reflecting high patient satisfaction. Postoperative symptoms such as pain, swelling, warmth, and tightness were noted but resolved completely within three months, with no severe complications reported. Conclusion: This study highlights the efficacy of nasolabial fat liposuction with a thread lift in reducing nasolabial folds and enhancing facial rejuvenation. Objective 3D imaging confirmed fat volume reduction, while high patient satisfaction reinforced its effectiveness. Mild postoperative symptoms resolved within three months, with no severe complications. These findings suggest this combined approach is a safe, effective option for individuals in their 20s to 50s seeking facial contour refinement.
