Objectives: To evaluate the efficacy of thread lifts in combination with arm liposuction for improving skin laxity in the upper arms, particularly in cases with mild to moderate skin sagging. This study aims to assess whether thread lifts can serve as a minimally invasive alternative to brachioplasty, particularly for Asian patients who are more prone to keloid formation. Introduction: Arm liposuction is one of the most commonly performed body contouring procedures in Japan. Due to hormonal factors, subcutaneous fat tends to accumulate and persist in the upper arms, making liposuction a popular choice among women. However, the “batwing” area is prone to skin laxity after fat removal, particularly in cases where over 600cc of pure fat is extracted or in patients over 40 years old. In Western countries, brachioplasty is commonly performed alongside arm liposuction to address skin laxity. However, Asian patients have a higher tendency for keloid scarring, making brachioplasty Materials / method: At our clinic, thread lifts are performed in conjunction with arm liposuction using PDO (polydioxanone) threads, inserting 4-6 threads per side to achieve lifting effects. This case report focuses on a 54-year-old female patient, detailing the surgical method and postoperative course. The patient’s preoperative condition, postoperative progress, and skin tightening effects were evaluated over time. Results: The combination of arm liposuction and thread lifts demonstrated a significant reduction in skin laxity, particularly in the batwing area. In the presented case, the sagging skin showed visible improvement, with a noticeable lifting effect compared to traditional liposuction alone. The integration of thread lifts during the contraction phase of recovery contributed to enhanced and prolonged skin tightening, minimizing the risk of excessive skin redundancy post-liposuction. Conclusion: Thread lifts combined with arm liposuction are an effective and minimally invasive method for addressing mild to moderate skin laxity. While brachioplasty remains the gold standard for severe cases, thread lifts provide a scar-free alternative for patients, particularly those of Asian descent, who are at higher risk for keloid formation. Additionally, when performed concurrently with liposuction, thread lifts leverage the natural contraction process of healing, leading to sustained improvements in skin tightness. This approach may offer a viable long-term solution for upper arm contouring with
