BACKGROUND: Tear trough deformity, hyperpigmentation and skin laxity of the lower eyelid makes individuals appear fatigued and elderly. Many patients prefer less invasive, cosmetic correction of the aged lower eyelid. PDO barbed threads introduced braided fine threads design, which works as a template for attraction the regenerative factors and for cells’ migration and proliferation. The purpose of this study 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.
MATERIALS AND METHODS: Total thirty 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. 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 (“SCA” group). Results were evaluated subjectively, based on the patients’ satisfaction rates, and objectively, by photographs’ evaluation.
RESULTS: According to Barton’s grading system: seven months after the treatment, there was statistical significant difference between the two groups: 1.733±0.74 in the non-SCA group and 0.733±0.83 in the SCA group (p<0.05). Based on patients’ self-assessment: there was significant difference at 7 month after the treatment: 2.86±0.84 in “non-SCA” group and 3.76±0.90 in “SCA” group, p<0.05. Complications such as persistent swelling, hematoma, skin irregularity, and infection were not observed during follow-up assessments.
CONCLUSION: The application of PDO braided type threads (N-scaffold) as a 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, non-invasive tool for the aged lower eyelids rejuvenation.
