Ablative and fractional lasers are used for periorbital rejuvenation, with different downtime, side effects, and efficacy.
To compare effects of fractional 1,550-nm ytterbium- and erbium-doped (Yb/Er) fiber laser and variable square pulse (VSP) 2,940-nm erbium-doped yttrium aluminum garnet (Er:YAG) laser treatment for periorbital wrinkles.
This side-by-side comparison study randomized 22 women with mild to moderate periorbital rhytides to receive three treatments with fractional 1,550-nm Yb/Er fiber laser or 2,940-nm Er:YAG laser treatment on either side at 4-week intervals. A video camera was used for objective assessment of wrinkles. Standardized photographs, patient satisfaction, side effects, and pain score were recorded.
Twenty subjects completed the study. The median change in wrinkle measurement 3 months after laser treatments from baseline of the fractional Yb/Er fiber laser side was -3.03 versus -3.09 on the VSP Er:YAG side (p = .63, Wilcoxon signed-rank test). There was no significant difference in degree of wrinkle improvement analyzed according to global assessment between the sides (p = .25, Wilcoxon signed-rank test). Less downtime correlated with greater patient satisfaction of the fractional laser treatment . Two subjects experienced hyperpigmentation.
Fractional Yb/Er fiber and VSP Er:YAG lasers are effective in improving periorbital wrinkles in Asians, with minimal side effects.
消融性和分段式激光被用于眶周年轻化,它们具有不同的停工期、副作用和疗效。
比较分段式 1550nm 掺镱和掺铒光纤激光(Yb/Er)与可变方波脉冲(VSP)2940nm 掺铒钇铝石榴石(Er:YAG)激光治疗眶周皱纹的效果。
这项并列对比研究将 22 名眶周存在轻至中度皱纹的女性随机分为两组,分别接受 3 次分段式 1550nm Yb/Er 光纤激光或 2940nm Er:YAG 激光治疗,治疗间隔为 4 周。使用摄像机对皱纹进行客观评估。记录标准照片、患者满意度、副作用和疼痛评分。
20 名受试者完成了研究。激光治疗 3 个月后,从基线起,Yb/Er 光纤激光侧的皱纹测量中位数变化为-3.03,VSP Er:YAG 侧为-3.09(p =.63,Wilcoxon 符号秩检验)。根据两侧的总体评估分析,皱纹改善程度无显著差异(p =.25,Wilcoxon 符号秩检验)。停工期较短与患者对光纤激光治疗的满意度较高相关。有 2 名患者出现了色素沉着过度。
分段式 Yb/Er 光纤和 VSP Er:YAG 激光在亚洲人群中治疗眶周皱纹有效,副作用轻微。
