Acoustic wave therapy is a novel facial tightening technique that involves nonthermal penetration of the skin and subcutaneous tissue, affecting cells and their metabolism, and resulting in an increased release of unwanted fat and activation of blood and lymphatic flow in tissues. The objective of this study was to investigate the effectiveness of acoustic wave therapy.
STUDY DESIGN/MATERIALS AND METHODS: A total of 333 patients underwent multiple facial tightening treatment sessions using focused and radial acoustic waves. Each patient received 2,000-3,000 pulses of focused acoustic waves at a power of 0.45-0.88 mJ/mm with a pulse frequency of 3-5 Hz and 4,000 pulses of radial acoustic waves at 4-bar power at a frequency of 21 Hz. These sessions were performed more than three times, and treatments were repeated at 1-month intervals. Digital photographs superimposed three-dimensional volumetric assessments, and three-dimensional skin surface displacement calculations using vectors were used to evaluate the results 12 months after the last treatment. Patients also evaluated the results using a 5-point Likert scale.
Improvements in skin texture, clarity, and laxity were observed in digital photographs. Superimposed three-dimensional color images showed marked volumetric reduction and/or formative modification for even contour toward the lower mid-face. Most vectors showed three-dimensional skin surface displacement at the lateral sides of the temples, cheeks, and chin, in an upward direction. These results were obtained and sustained for up to 12 months without edematous reactions. Almost all patients reported improvement, with 79% reporting "good" or "excellent" improvement. Complications were minor and transitory. Persistent side effects were not observed.
Acoustic wave therapy could be used as a standard facial tightening treatment, with skin rejuvenation effects shown on digital photographs and three-dimensional quantification assessments. This noninvasive acoustic wave approach was found to be a safe, long-lasting, and effective method for facial tightening. Lasers Surg. Med. 00:00-00, 2020. © 2020 Wiley Periodicals LLC.
声波治疗是一种新颖的面部紧致技术，涉及非热穿透皮肤和皮下组织，影响细胞及其新陈代谢，导致多余脂肪的释放增加，并激活血液和淋巴在组织中的流动。本研究的目的是探讨声波治疗的有效性。
研究设计/材料和方法：共有 333 名患者接受了多次聚焦和径向声波的面部紧致治疗。每位患者接受 2000-3000 次聚焦声波脉冲，功率为 0.45-0.88mJ/mm，脉冲频率为 3-5Hz，4000 次径向声波脉冲，功率为 4 巴，频率为 21Hz。这些疗程进行了三次以上，每隔一个月重复治疗。使用数字照片叠加三维体积评估和使用向量进行三维皮肤表面位移计算来评估最后一次治疗后 12 个月的结果。患者还使用 5 分李克特量表评估结果。
在数字照片中观察到皮肤质地、清晰度和松弛度的改善。叠加的三维彩色图像显示出明显的体积减少和/或成形修饰，以使中下脸轮廓更加均匀。大多数向量显示出太阳穴、脸颊和下巴侧面的三维皮肤表面位移，呈向上方向。这些结果在 12 个月内得到并维持，没有水肿反应。几乎所有患者都报告有所改善，79%的患者报告“好”或“优”的改善。并发症轻微且短暂。未观察到持续的副作用。
声波治疗可作为一种标准的面部紧致治疗方法，数字照片和三维定量评估显示皮肤年轻化效果。这种非侵入性的声波方法被发现是一种安全、持久和有效的面部紧致方法。激光外科学杂志。00:00-00，2020. 2020 年威利父子公司版权所有。
