Volume restoration remains the principal target to be addressed when approaching midface rejuvenation, and absorbable sutures can create a suspension system that addresses ptotic skin located primarily in the midface. The aim of this pilot study was to investigate the effectiveness in lifting sagging tissue and to determine the outcome of thread lifting procedures of the midface. Six participants were enrolled and treated with suspension threads to correct mild to moderate ptosis of the flabby tissues of the midface. Volumetric changes were calculated at t0 (pretreatment), t1(120 days) and t2 (365 days), with a mean follow-up time of 349.64 days, (range from 304 to 380.5 days). Results showed an overall average improvement of 5.59 mL at 120 days (t0-t1) after thread implantation, up to a mean value of 4.16 mL at the end of the 350 days follow up (t0-t2). A comparison was made in between and statistical analysis was performed with level of significance set at P < .05. The records shown suggest that it is possible to achieve volume restoration which lasts up to 12 months as all parameters improved significantly (P < .05) at t1 and at t2 with respect to t0. Facial tissues suspension by means of threads is therefore safe and effective, as it is possible to achieve tissue repositioning which lasts up to 12 months for the correction of mild to moderate ptosis of the midface.
体积恢复仍然是中面部年轻化时需要解决的主要目标，可吸收缝线可以创建一个悬带系统，主要解决中面部的下垂皮肤。本研究旨在探讨提升下垂组织的效果，并确定中面部线雕提升程序的结果。共招募了 6 名参与者，他们使用悬吊缝线来矫正中面部松弛组织的轻度至中度下垂。在 t0（治疗前）、t1（120 天）和 t2（365 天）测量体积变化，平均随访时间为 349.64 天（范围为 304 至 380.5 天）。结果显示，在植入缝线后的 120 天（t0-t1），总体平均改善 5.59 毫升，在 350 天随访结束时（t0-t2），平均改善值为 4.16 毫升。对其进行了比较，并进行了统计学分析，置信水平为 P <.05。记录显示，通过线雕可以实现长达 12 个月的体积恢复，因为所有参数在 t1 和 t2 时均显著改善（P <.05），与 t0 相比。因此，通过线雕对面部组织进行悬吊是安全有效的，因为可以实现组织重新定位，持续长达 12 个月，以矫正中面部的轻度至中度下垂。
