Abstract：
BACKGROUND: Ultrasound-assisted liposuction (UAL) has become popular because of its favorable outcomes in fat emulsification, blood loss reduction, and skin tightening. This study aimed to compare the effects of two UAL devices on the abdomen by assessing postsurgery skin biomechanical properties.
METHODS: This single-blind, prospective study (2020-2022) involved 13 liposuction procedures performed on patients without chronic diseases. Each patient\'s abdomen was divided vertically from the xiphoid to the perineum. Vibration amplification of sound energy at resonance (VASER)-assisted liposuction (Solta Medical, Inc., Hayward, CA) was performed on one half, while the other half underwent liposuction with high-frequency ultrasound energy (HEUS)-assisted technology. Skin biomechanical measurements, including distensibility, net elasticity, biological elasticity, hydration, erythema, melanin, and skin firmness, were taken at 12 and 24 months postsurgery, focusing on the anterior abdomen, 8 cm to the right and left of the umbilicus.
RESULTS: Analysis of the above skin biomechanical measurements revealed no significant differences between the HEUS and VASER devices, except for skin firmness, which showed a notable increase following HEUS surgery. Patient-perceived clinical differences were assessed via nonvalidated questionnaires, revealing no distinctions between devices.
CONCLUSIONS: Biomechanical skin results post-UAL surgery with these devices on the abdomen were not significantly different, although HEUS revealed increased skin firmness. This suggests that HEUS-assisted technology, akin to other devices, is a viable option for UAL procedures.

摘要：
背景：超声辅助吸脂术（UAL）由于其在脂肪乳化中的有利结果而变得流行，减少失血,和皮肤收紧。本研究旨在通过评估手术后皮肤生物力学特性来比较两种UAL设备对腹部的影响。
方法：这种单盲，前瞻性研究(2020-2022年)涉及对无慢性病患者进行的13项抽脂手术.每个患者的腹部从剑突到会阴垂直分开。共振声能的振动放大（VASER）辅助吸脂术（SoltaMedical，Inc.,海沃德,CA)是在一半上进行的，而另一半接受了高频超声能量（HEUS）辅助技术的吸脂术。皮肤生物力学测量，包括扩张性，净弹性，生物弹性，水合作用,红斑,黑色素,和皮肤紧致度，在手术后12个月和24个月，专注于前腹部，8厘米左右脐。
结果：对上述皮肤生物力学测量结果的分析表明，HEUS和VASER装置之间没有显着差异，除了皮肤紧致度，在HEUS手术后显示显着增加。患者感知的临床差异通过未经验证的问卷进行评估，显示设备之间没有区别。
结论：使用这些装置在腹部进行UAL手术后的生物力学皮肤结果没有显着差异，尽管HEUS显示皮肤紧实度增加。这表明HEUS辅助技术，类似于其他设备，是UAL程序的可行选择。
