背景:通过减少皱纹/细纹来收紧面部皮肤是美学领域中非常需要的程序。虽然有研究集中在能源的类型,热能的总量,和受影响的深度,没有报告研究热能的形状和皮肤紧致的方向性之间的关系。我们开发了一种特定的方法,以连续的平行线向真皮施加热能,像一根线,垂直于松弛皮肤张力线(RSTL),使用同步超声平行束技术进行矢量化胶原蛋白收缩。
目的:为了评估安全性,拧紧能力,和使用高强度的热线程技术™的方向性,高频,平行超声波束。
方法:共34例,年龄在30至70岁之间的Fitzpatrick皮肤类型为2-4的男性和女性,表现出轻度至中度的皮肤松弛,参与。所有受试者都接受了一次使用热螺纹技术™的高强度治疗,高频平行超声波束覆盖整个面部和下区域。之前拍摄了3D临床图像,8周,治疗后24周。对捕获的3D图像进行定量图像分析,以客观地测量收缩的方向和距离。
结果:从基线(0mm)到治疗后8周和24周的平均收缩距离分别为1.91±0.61mm(p<0.001)和1.96±0.67mm(p<0.001)。关于治疗后24周的收缩方向,收缩方向与基轴之间形成的角度,垂直于RSTL,为+9.85°±32.94°。在34个案例中,图28所示的实施例满足标准,其角度在基轴的±22.5°内(p<0.001)。0-5量表上的平均疼痛评分(0表示没有疼痛,最大疼痛5)为2.63±0.78。在治疗或观察期间未报告副作用。
结论:热线程技术™利用高强度,高频,平行超声束被证明是临床安全和有效的矢量面部皮肤收紧。
Facial skin tightening with wrinkle/fine line reduction is a highly demanded procedure in the aesthetic field. Although there are studies focused on the types of energy sources, the total amount of thermal energy, and the affected depth, there have been no reports examining the relationship between the shape of thermal energy and the directivity of skin tightening. We have developed a specific method to apply thermal energy to the dermis in continuous parallel lines, resembling a thread, perpendicular to the Relaxed Skin Tension Lines (RSTL) for vectorized collagen contraction using synchronous ultrasound parallel beam technology.
To evaluate the safety, tightening capability, and directivity of the Thermal Thread Technique™ utilizing a high-intensity, high-frequency, parallel ultrasound beam.
A total of 34 cases, both males and females aged between 30 and 70 years with Fitzpatrick skin types 2-4, exhibiting mild to moderate skin laxity, participated. All subjects received one treatment using the Thermal Thread Technique™ utilizing high-intensity, high-frequency parallel ultrasound beam to cover the full face and submental area. 3D clinical images were captured before, 8 weeks, and 24 weeks after the treatment. A quantitative image analysis of captured 3D images was performed to objectively measure the direction and distance of contraction.
The average contraction distance from baseline (0 mm) to 8 weeks and 24 weeks posttreatment were 1.91 ± 0.61 mm (p < 0.001) and 1.96 ± 0.67 mm (p < 0.001) respectively. Regarding the contraction direction at 24 weeks posttreatment, the angle formed between the contraction direction and the base axis, which is perpendicular to the RSTL, was + 9.85° ± 32.94°. Out of 34 cases, 28 met the criteria with the angle within ±22.5° of the base axis (p < 0.001). The average pain score on a 0-5 scale (0 being no pain, and 5 being maximum pain) was 2.63 ± 0.78. No side effects were reported during the treatment or observation period.
The Thermal Thread Technique™ utilizing a high-intensity, high-frequency, parallel ultrasound beam was proven to be clinically safe and effective for vectorized facial skin tightening.
