Abstract
Q-switched (QS) lasers are widely considered the gold standard for tattoo removal, with excellent clinical results, impressive predictability, and a good safety profile. The generation of giant pulses by the method of Q-switching is responsible for the unique laser-tissue interaction that is seen in tattoo removal by QS lasers. The QS lasers work by impaction and dissolution of the tattoo pigments. Mechanical fragmentation of the tattoo pigments encased in intracellular lamellated organelles followed by their phagocytosis by macrophages is thought to be the major event in the clearance of pigments by QS lasers. A few novel techniques have been tried in recent times to hasten the clearance of tattoo pigments.
摘要
调Q（QS）激光被广泛认为是纹身去除的金标准，具有出色的临床效果、令人印象深刻的可预测性和良好的安全性。通过调Q方法产生巨脉冲，这是QS激光在纹身去除中所呈现的独特激光与组织相互作用的原因。QS激光通过撞击和溶解纹身色素起作用。包裹在细胞内层状细胞器中的纹身色素发生机械破碎，随后被巨噬细胞吞噬，这被认为是QS激光清除色素的主要过程。近年来，人们尝试了一些新技术来加速纹身色素的清除。
