[摘要]目的：探讨Q开关Nd：YAG激光多次低能量祛除文身的临床疗效观察。方法：临床选取21例文身患者，治疗采用自身对比:A区为试验区，使用Q开关1064nm波长激光，光斑直径4～6mm，能量密度为2.0～4.0J/cm2，平行均匀照射1遍，术后即刻反应皮损变白霜，无皮肤出血点,每天治疗1次，连续治疗3～4次；B区为对照区，使用Q开关1064nm波长激光，光斑直径3～4mm，能量密度为5.0～8.0J/cm2，均匀照射1遍，即刻反应皮损灰白或皮肤出血。两组病例均于术后6个月观察疗效。结果：术后6个月观察，试验区：治愈9例(42.8%)，显效12例(57.2%)，无瘢痕形成；对照区：治愈3例(14%)，显效5例(24%)，好转13例(62%)，2例(9.5%)出现轻度增生性瘢痕。结论：采用Q开关Nd：YAG激光多次低能量治疗文身的方法可加快文身消退病程，减少文身治疗中能量密度过大形成瘢痕或色素脱失的风险，为文身治疗提供一种新的治疗方法。

Abstract: Objective To evaluate the efficacy of multiple low-energy Q switched laser treatment for tattoo patients. Methods 21 patients (skin typeIV-V, mean age 21.4) with tattoos were enrolled,and the tattoo lesions were divided into two parts on one person.: Lesions in part A (the experimental group) were treated with Q-switched laser (wavelength 1064nm ,spotsize 4～6mm, fluence 2.0～4.0J/cm2 , pulse repetition rate 10 Hz). The lesions became white-frosting after irradiation .The treatment was performed once a day for 3 days.Lesions in part B (the control group) were treated with Q-switched laser (wavelength 1064nm, spotsize 3～4mm, fluence 5.0～8.0J/cm2 , pulse repetition rate 10 Hz) for one session. The evaluation was performed 6 months after treatment. Results In group A, all cases achieved different degree of improvement :42.8% of the tattoos were cured, 57.2% of the tattoos were excellent, without scar formation. In group B: all case achieved different degree of improvement :14.0% of the tattoos were cured, 24.0% of the tattoos were excellent and 62.0% of them were improved. Slightly hypertrophic scar formation occurred to 2 cases in group B. Conclusion Application of the multiple low-energy Q-switched laser is effective and safe in the treatment of tattoos ,and the side effects was rare, thereby it give a new choice for the patients with tattoos ......
