Q-switched (QS) lasers are the gold standard for tattoo removal. The purpose of the present study was to gain a more comprehensive understanding of the factors that influence the efficacy of QS lasers and their associated complications in the removal of tattoos in China.
Clinical data of 266 patients were analyzed retrospectively. The tattoo clearance rate was evaluated using the 4-point scale. The Cox regression model was applied to analyze the factors that affected the efficacy of QS lasers in tattoo removal. In addition, treatment-related adverse reactions were analyzed.
The results showed that several variables had a statistically significant effect (p < 0.05) on the efficacy of QS laser-mediated tattoo removal treatment, including the patients' age, the tattoo's age, type, color, or ink density and the number of treatments. A variety of adverse responses occurred during the laser treatment. The overall incidence of adverse responses was approximately 24.06%, including pigmentation, hypopigmentation, bulla formation, allergic reactions, and skin texture changes or hypertrophic scarring.
Some factors may influence the efficacy of QS lasers in the treatment of tattoos and certain adverse reactions may occur during this process.
调Q（QS）激光是纹身去除的金标准。本研究的目的是更全面地了解影响QS激光在中国纹身去除效果及其相关并发症的因素。
回顾性分析266例患者的临床资料。使用4分制评估纹身清除率。应用Cox回归模型分析影响QS激光纹身去除效果的因素。此外，对治疗相关的不良反应进行分析。
结果显示，几个变量对QS激光介导的纹身去除治疗效果有统计学显著影响（p < 0.05），包括患者年龄、纹身的年限、类型、颜色、墨水密度以及治疗次数。激光治疗期间出现了多种不良反应。不良反应的总发生率约为24.06%，包括色素沉着、色素减退、水疱形成、过敏反应以及皮肤质地改变或肥厚性瘢痕。
一些因素可能影响QS激光治疗纹身的效果，在此过程中可能会出现某些不良反应。
