BACKGROUND: Laser tattoo removal conventionally uses Q-switched (QS) lasers, but they require multiple sittings, and the end results depend largely on the type of tattoo treated. In pigmented skin, due to the competing epidermal pigment results, laser results in tattoo are slow and inadequate. OBJECTIVE: To evaluate the efficacy of a combined use of ultrapulse CO2 and QS Nd:YAG (1064 nm) laser in the treatment of tattoos in Indian skin. MATERIALS AND METHODS: A split-lesion trial was carried out in five patients, with the left side of tattoos receiving the QS Nd:YAG (1064 nm) and the right side, a sequential combination of Up CO2 and QS Nd: YAG at 6 weeks interval with a maximum of six sittings. Outcome assessment was carried out by a blinded assessor using standardized photography. An assessment of physician improvement score, side-effects score, and patient satisfaction score was taken during and at the end of the study. RESULTS: There was a statistically significant improvement on the combination side(physician improvement score -3.7 vs. 1.87: P = 0.0019) which occurred earlier with fewer sittings (1.7 vs. 6). There was no statistically significant difference in the side effects. CONCLUSION: A combination of an Up CO2 laser with QS Nd: YAG laser is a promising tool for rapid and effective removal of blue-black/blue amateur tattoo in pigmented skin.
背景:激光纹身去除术传统上使用 Q 开关(QS)激光,但需要多次治疗,最终效果在很大程度上取决于所治疗的纹身类型。在色素性皮肤中,由于竞争的表皮色素结果,激光对纹身的治疗效果缓慢且不足。
目的:评估超脉冲 CO2 和 QS Nd:YAG(1064nm)激光联合应用于印度皮肤纹身治疗的疗效。
材料和方法:对五名患者进行了半皮损试验,左侧纹身接受 QS Nd:YAG(1064nm)激光治疗,右侧纹身则在 6 周间隔内接受超脉冲 CO2 和 QS Nd:YAG 的序贯联合治疗,最多进行六次治疗。通过盲法评估者使用标准化摄影进行疗效评估。在研究期间和结束时,对医生改善评分、副作用评分和患者满意度评分进行评估。
结果:联合治疗侧(医生改善评分-3.7 与 1.87:P=0.0019)有统计学显著改善,且治疗次数更少(1.7 与 6)。副作用无统计学显著差异。
结论:超脉冲 CO2 激光与 QS Nd:YAG 激光联合应用是一种快速有效去除色素性皮肤中蓝黑色/蓝色业余纹身的有前途的工具。
