The facial aging process produces changes that are characteristic of the superficial and deep fat framework and skin layers. Subdermal suspension with threads enables the sagging tissues to be lifted by means of a minimally invasive, closed procedure without surgical dissection. This observational study has been carried out on the basis of standardized tridimensional photographic analysis and measurement, aimed at determining objective, repetitive, and reliable evaluation of the soft tissue suspension technique.
Eight participants were enrolled in this pilot study presenting with mild to moderate ptosis of the jawline tissues. Patient photographs were taken before (t0), immediately after threads implantation (t1), and at the following visit (t2). Each image captured before thread insertion was registered by the software and surface linear lengths in between the mentioned points were calculated.
The result showed an overall average improvement in the "tragus-to-marionette distance" (C-A) and the "tragus-to-jowl distance" after a mean follow-up time of 8.16 months (t0-t2). All analyzed parameters improved significantly (P < 0.05) at t1 and at t2 with respect to t0.
This pilot study suggest that facial tissue suspension by means of poli-lactic/poli-caprolactone threads is safe and effective in treating skin flaws that affect mild-to-moderate ptosis of the jawline up to 8 months.
面部衰老过程会产生一些特征性变化,这些变化涉及浅表和深层脂肪结构以及皮肤层。皮下埋线悬吊术能够通过一种微创的闭合手术来提升松弛的组织,而无需进行手术解剖。这项观察性研究是在标准化三维摄影分析和测量的基础上进行的,旨在确定对软组织悬吊技术进行客观、可重复且可靠的评估。
八名参与者被纳入这项初步研究,他们均表现出轻度至中度的下颌缘组织下垂。在埋线前(t0)、埋线后即刻(t1)以及随后的随访时(t2)拍摄患者照片。在埋线前拍摄的每张图像都由软件进行记录,并计算上述各点之间的表面线性长度。
结果显示,在平均随访8.16个月(t0 - t2)后,“耳屏至木偶纹距离”(C - A)和“耳屏至颌下距离”总体平均有所改善。与t0相比,所有分析参数在t1和t2时均有显著改善(P < 0.05)。
这项初步研究表明,通过聚乳酸/聚己内酯线进行面部组织悬吊术在治疗影响下颌缘轻度至中度下垂的皮肤瑕疵方面,长达8个月是安全有效的。
