Tear trough deformity, hyperpigmentation, and skin laxity of the lower eyelid make individuals appear fatigued and elderly. Many patients prefer less invasive, cosmetic correction of the aged lower eyelid. Polydioxanone (PDO)-barbed threads introduced braided fine threads design, which works as a template for attraction of the regenerative factors and for cells' migration and proliferation. The purpose of this study was to estimate the outcomes of simultaneous additional application of braided type PDO threads (N-scaffold) for aged lower eyelids' rejuvenation in patients, who underwent the midface PDO thread lifting.
A total of 30 patients with mildly loose skin in the facial area, who underwent the thread lifting using PDO threads, were included in this study. Patients were divided into two groups, 15 patients per group. The first group underwent the midface thread lifting using PDO threads ("non-SCA" group). The second group underwent midface thread lifting in combination with braided PDO threads for tear trough deformity improvement ("N-scaffold" group). The results were evaluated subjectively, based on the patients' satisfaction rates, and objectively, by evaluating photographs.
According to Barton's grading system, 7 months after the treatment, there was a statistically significant difference between the two groups: 1.733 ± 0.74 in the non-SCA group and 0.733 ± 0.83 in the N-scaffold group (p < 0.05). Based on patients' self-assessment, there was a significant difference at 7 months after the treatment: 2.86 ± 0.84 in "non-SCA" group and 3.76 ± 0.90 in "N-scaffold" group, p < 0.05. Complications such as persistent swelling, hematoma, skin irregularity, and infection were not observed during follow-up assessments.
The application of braided type PDO threads (N-scaffold) as part of the midface thread lifting, for aged lower eyelids rejuvenation appears to be effective and safe within a period. This study suggests that PDO threads insertion may be a useful, additional, and non-invasive tool for the aged lower eyelids rejuvenation.
泪槽畸形、下眼睑色素沉着和皮肤松弛会使个体看起来疲惫和衰老。许多患者更喜欢更微创的、美容性的下眼睑衰老矫正。聚二氧环己酮（PDO）带刺线引入了编织细线设计，它作为吸引再生因子和细胞迁移和增殖的模板。本研究的目的是评估在接受 PD0 线中面部提升的患者中同时应用编织型 PDO 线（N 支架）进行下眼睑老化的同时改善的效果。
共有 30 名轻度面部皮肤松弛的患者纳入本研究，他们均接受 PDO 线中面部提升。患者分为两组，每组 15 例。第一组接受 PD0 线中面部线提升（“非 SCA”组）。第二组接受中面部线提升联合编织型 PDO 线改善泪槽畸形（“N 支架”组）。结果通过患者满意度进行主观评估，通过照片评估进行客观评估。
根据 Barton 分级系统，治疗后 7 个月，两组之间存在统计学差异：非 SCA 组为 1.733±0.74，N 支架组为 0.733±0.83（p<0.05）。根据患者的自我评估，治疗后 7 个月时存在显著差异：非 SCA 组为 2.86±0.84，N 支架组为 3.76±0.90（p<0.05）。随访评估期间未观察到持续性肿胀、血肿、皮肤不平整和感染等并发症。
作为中面部线提升的一部分，编织型 PDO 线（N 支架）的应用在下眼睑年轻化中在一定时期内是有效且安全的。本研究表明，PD0 线插入可能是一种有用的、额外的、非侵入性的下眼睑年轻化工具。
