Until the recent development of the Q-switched lasers, it was not possible to remove tattoos without causing scarring, sometimes very disfiguring. Variations in wavelengths and pulse widths used may result in different clinical effectiveness or risks. The objective of this study was to determine the effectiveness of the alexandrite laser in removing professional and amateur tattoo pigment without adverse tissue response.
We describe the clinical and histologic effects of the use of a new Q-switched laser for treatment of tattoos, the alexandrite laser (wavelength, 755 nm; pulse width, 100 nanoseconds). The results of treatment of 17 patients with professional tattoos and eight patients with amateur tattoos are analyzed. Greater than 95% removal of tattoo pigment averaged 8.9 treatment sessions. Transient hypopigmentation occurred in approximately 50% of patients, and transient textural surface changes occurred in 12%.
The alexandrite laser is a safe and effective treatment modality for removal of black and blue-black tattoo pigment.
在调Q激光最近发展之前，去除纹身而不造成瘢痕是不可能的，有时瘢痕会非常毁容。所使用的波长和脉冲宽度的变化可能导致不同的临床效果或风险。本研究的目的是确定翠绿宝石激光在去除专业和业余纹身色素时不产生不良组织反应的有效性。
我们描述了一种新型调Q激光——翠绿宝石激光（波长755nm，脉冲宽度100纳秒）用于治疗纹身的临床和组织学效果。分析了17例专业纹身患者和8例业余纹身患者的治疗结果。纹身色素平均去除率超过95%需要8.9次治疗。约50%的患者出现短暂性色素减退，12%的患者出现短暂性质地表面改变。
翠绿宝石激光是去除黑色和蓝黑色纹身色素的一种安全有效的治疗方式。
