Several laser techniques have been proposed for the removal of decorative tattoos. The lasers that have been used most successfully are Q-switched red or near-infrared systems because of their ability to target tattoo pigment selectively with minimal risk of scarring or permanent pigmentary changes.
The objectives of this study were to determine the clinical effectiveness of the newest Q-switched system, the alexandrite laser, in removing amateur and professional tattoos and to observe side effects.
Twenty-four multicolored professional tattoos and 18 blue-black amateur tattoos were treated with the Q-switched alexandrite laser (755 nm, 100 nsec) at 2-month intervals until total clearing was achieved. The 510 nm pulsed dye laser was used to treat tattoos that contained red pigment.
Professional tattoos required an average of 8.5 alexandrite laser treatments for total clearance, whereas only 4.6 treatments were necessary to remove amateur tattoos. Red tattoo pigment was successfully treated with an average of two 510 nm pulsed dye laser sessions. No scarring or long-standing pigmentary changes were seen in laser-irradiated skin.
The Q-switched alexandrite laser is highly effective in removing multicolored professional and amateur tattoos without adverse sequelae. The 510 nm pulsed dye laser was useful in eliminating red tattoo pigment.
已提出多种激光技术用于去除纹身。最成功使用的激光是调Q红宝石激光，它能选择性地作用于纹身色素，对周围组织的热损伤小，术后瘢痕形成和色素沉着的发生率低。
探讨新型调Q开关翠绿宝石激光治疗业余和专业纹身的临床疗效，并观察其副作用。
应用调Q开关翠绿宝石激光（波长755nm，脉宽100ns）对24例多色专业纹身和18例蓝黑色业余纹身进行治疗，每次间隔2个月，直至纹身完全清除。对含有红色色素的纹身采用510nm脉冲染料激光治疗。
专业纹身平均需要8.5次翠绿宝石激光治疗才能完全清除，而业余纹身平均只需4.6次治疗。红色纹身色素平均经2次510nm脉冲染料激光治疗即可成功清除。激光照射部位未见瘢痕形成或长期色素沉着。
调Q开关翠绿宝石激光能有效清除多色专业和业余纹身，且无明显不良反应。510nm脉冲染料激光对清除红色纹身色素有效。
