Many modalities for the treatment of tattoos and pigmented lesions produce a greater risk of complications in Fitzpatrick types V and VI skin because of an increased incidence of adverse pigmentary changes and keloidal scarring. In fair-skinned persons Q-switched lasers have proved effective in removing pigmented lesions and tattoos without scarring.
This study was conducted to determine the efficacy and effects of Q-switched lasers on a small series of darkly pigmented patients with tattoos.
Four patients of Ethiopian origin with facial and neck tribal tattoos were treated with both the Q-switched ruby and Nd:YAG lasers. One black woman with a multicolored tattoo on the mid chest was treated with the Q-switched ruby laser.
Clearing of all lesions was seen. The treatments did not result in scarring or permanent pigment changes other than the ones intended.
Our results indicate that in darkly pigmented patients, Q-switched laser treatment of tattoos can be performed successfully. The longer wavelength Q-switched Nd:YAG laser is recommended when removing tattoos in darker complected persons. A test treatment is advised before treatment of large skin areas.
由于色素沉着不良变化和瘢痕疙瘩形成的发生率增加，许多治疗纹身和色素沉着病变的方法在 Fitzpatrick V 型和 VI 型皮肤中产生并发症的风险更高。在皮肤白皙的人群中，调 Q 激光已被证明可有效去除色素沉着病变和纹身且不留疤痕。
本研究旨在确定调 Q 激光对一小系列深色皮肤纹身患者的疗效和效果。
对 4 名有面部和颈部部落纹身的埃塞俄比亚裔患者使用调 Q 红宝石激光和 Nd:YAG 激光进行治疗。一名胸部中部有彩色纹身的黑人女性接受了调 Q 红宝石激光治疗。
所有病变均清除。治疗除预期效果外，未导致疤痕形成或永久性色素改变。
我们的结果表明，在深色皮肤患者中，调 Q 激光治疗纹身可以成功进行。在肤色较深的人群中去除纹身时，建议使用波长较长的调 Q Nd:YAG 激光。在治疗大面积皮肤区域之前，建议进行试验性治疗。
