Abstract

The purpose of this study was to evaluate the safety and efficacy of a new combined method of Q-S laser-assisted tattoo removal. Ten patients with 13 professional, mostly mono-chromatic black tattoos were recruited. All tattoos received the same Q-S laser treatment sequence. An objective evaluation of tattoo clearing was assessed by careful analysis of a standardized collection of digital images taken from each tattoo, 2 months after each laser session, with the help of a custom-made pigment-fading percentage photographic ruler. The percentages of pigment clearance and side effects were evaluated by 4 independent dermatologists. Patient satisfaction and perceived discomfort during and post-procedure were evaluated according to specific scales. Clinical evaluators confirmed an average photographic pigment clearance of 97% after a median 4.85 treatment sessions. The Frac-Tat® method required 40% fewer sessions compared to those calculated by Kirby-Desai estimates. Photographic assessment of laser-exposed skin quality performed 2 months after tattoo clearing was considered almost comparable with untreated peripheral skin, confirming a very low side effect score. The Frac-Tat QS laser-assisted tattoo removal sequence used in our study showed a high degree of safety and efficiency, clearing exogenous pigments in a relatively few number of sessions. Preliminary ablative photo-acoustic fractional 1064-nm Q-S laser micro-drilling was considered an essential step in optimizing tattoo removal, increasing wavelength-independent micro-columnar clearing of deeper dermal exogenous pigments. Our preliminary observations also confirmed a significant improvement of tattoo procedure-induced micro-textural changes thanks to a tissue remodeling effect induced by the 1064-nm Q-S fractional laser photo-acoustic ablation.

摘要

本研究旨在评估一种新的 Q-S 激光辅助纹身去除联合方法的安全性和疗效。招募了 10 名患有 13 处专业纹身的患者,这些纹身主要是单色黑色纹身。所有纹身均接受相同的 Q-S 激光治疗序列。通过使用定制的色素消退百分比摄影标尺,仔细分析每次激光治疗后 2 个月从每个纹身采集的标准化数字图像,对纹身清除的客观评估。色素清除率和不良反应率由 4 位独立皮肤科医生评估。根据特定量表评估患者在治疗过程中和治疗后的满意度和感知不适。临床评估者在中位数 4.85 次治疗后确认平均摄影色素清除率为 97%。与 Kirby-Desai 估计值相比,Frac-Tat®方法需要少 40%的治疗次数。在清除纹身后 2 个月对激光暴露皮肤质量进行的摄影评估被认为与未处理的周边皮肤几乎相当,证实了非常低的不良反应评分。我们研究中使用的 Frac-Tat QS 激光辅助纹身去除序列显示出高度的安全性和效率,在相对较少的治疗次数内清除外源性色素。初步的消融性光声 1064nm Q-S 激光微钻被认为是优化纹身去除的重要步骤,增加了对深层真皮外源性色素的波长独立微柱清除。我们的初步观察结果还证实,由于 1064nm Q-S 分数激光光声消融引起的组织重塑效应,纹身治疗引起的微纹理变化得到了显著改善。
