摘要
目的和目的在过去的几十年里，面悬线一直被用于面部软组织的复位。尽管如此，目前尚不清楚哪种技术和/或材料对中下表面的提升效果最大。为了评估非手术提线，我们使用了一种新颖的“1点，2个目标，12个线程”矢量技术，通过水平皮肤位移、鼻唇沟、下颌线的体积变化以及中三分之一和下面部脂肪区的重新定位的3D成像进行了验证。材料和方法分析了6例高加索患者（35例女性，1例男性），平均年龄42±4岁，平均体重指数22.72±0.72kg/m2。使用21号、90毫米套管和“1点、2个目标、12根线”矢量技术，针对鼻唇沟和下颌线，引入了聚二氧杂环己酮双向锯齿状面部线。Vectra H2软件用于计算水平提升皮肤位移变化、鼻唇沟和下颌线的体积减少以及中间三分之一的体积重新定位。结果平均水平皮肤位移（左侧，2.75±1.17 mm vs右侧，2.84±1.40 mm）为2.80±1.06 mm，无统计学意义（p=0.8349）。鼻唇沟的平均体积变化为−0.09±0.47 cc（左侧，−0.02±0.45 cc vs右侧，−0.16±0.58 cc），无统计学显著性差异（p=0.1991）。下颌线的平均体积变化为-0.36±0.43 cc（左，-0.36±.43 cc vs右，-0.37±0.54 cc），无统计学显著差异（p=0.4561）。中浅脂肪区的平均体积重新定位为1.34±0.79 cc（左1.24±0.84 vs右1.43±1.01 cc），没有统计学上的显著差异（p=0.1897）。结论这是第一项产生客观测量螺纹非手术解剖提升的证据的研究。在临床实践中，利用数字软组织面部人体测量进行更多的临床研究对于验证这种非手术提升治疗至关重要。
Validation of Non-surgical Facial Lifting with PDO Thread using a 3D system
Aim and objectives
Facial suspension threads have been used in the last decades for the reposition of facial soft tissue. Nonetheless, it remains unclear which technique and/or material has the greatest lifting effect for the middle and lower face. To evaluate non-surgical thread lifts we used a novel “1 Point, 2 Targets, 12 Threads” Vectors technique, verified by 3D imaging of horizontal skin displacement, volume changes at the nasolabial sulcus, jawline, and repositioning of fat compartments in the middle third and lower face.
Material and methods
Thirty-six Caucasian patients (35 females and 1 male), with a mean age of 42 ± 4 years and a mean body mass index of 22.72 ± 0.72 kg/m2, were analyzed. Polydioxanone bidirectional cog-barbed facial threads were introduced using a 21-gauge, 90-mm cannula, and the “1 Point, 2 Targets, 12 Threads” Vectors technique aimed towards the nasolabial fold and the jawline. Vectra H2 software was used to calculate horizontal lift skin displacement changes, volume reduction in the nasolabial fold and jawline and volume reposition of the middle third.
Results
Mean horizontal skin displacement (left side, 2.75 ± 1.17 mm vs right side, 2.84 ± 1.40 mm) was 2.80 ± 1.06 mm, with no statistical significance (p = 0.8349). The mean volume change of the nasolabial fold was −0.09 ± 0.47 cc (left, −0.02 ± 0.45 cc vs right, −0.16 ± 0.58 cc), with no statistically significant difference (p = 0.1991). The mean volume change of jawline was −0.36 ± 0.43 cc (left, −0.36 ± 0.43 cc vs right, −0.37 ± 0.54 cc) with no statistically significant difference (p = 0.4561). Mean volume repositioning of the middle superficial fat compartments was 1.34 ± 0.79 cc (left 1.24 ± 0.84 vs right 1.43 ± 1.01 cc), with no statistically significant difference (p = 0.1897).
Conclusion
This is the first study to generate evidence of an objective measurement of non-surgical anatomical lifting with threads. More clinical studies utilising digital soft tissue facial anthropometry will be essential in clinical practice to verify this non-surgical lifting treatment.
