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.
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。
