Although tattoos are ancient and very popular among young people, it is also a reason for regret, and many people today have a desire to remove them. Among the possibilities for this, laser removal is the most successful procedure with the highest degree of pigment removal and the lowest risk of complications. This study was recorded on three patients with tattoos, and only the black pigments were removed. None of the patients involved had a history of skin allergies, skin cancer, and/or keloid formation. Case 1 had a professional tattoo removed in the right calf region in two sessions. Case 2 had an amateur tattoo that was removed on the scalp in three sessions. Finally, Case 3 had two professional tattoos, which were removed from the face in a total of eleven sessions. The following equipment was used: Spectra XT Q-Switched Nd:YAG 1064 nm with a pulse width of 5 ns; Pico Ultra 300 Nd:YAG 1064 nm with a pulse width of 300 ps; and SoftLight Q-Switched Nd:YAG 1064 nm with a pulse width of 17 ns. In general, satisfactory results were obtained, but hypopigmentation was present in Cases 1 and 3. This was probably due to sun exposure at the laser removal site, the short interval between the sessions, and/or higher radiant exposure combined with a smaller spot size, respectively. To achieve a successful tattoo removal in the higher phototypes and reduce unwanted effects, the professionals must know the best parameters to be used, as well as the adequate foundation on the individual characteristics of each patient and the tattoos. Furthermore, patient compliance with the pre/post session care and a suitable interval between the laser sessions are essential to avoid undesirable complications.
尽管纹身由来已久且在年轻人中非常流行,但它也可能令人后悔,如今许多人都有去除纹身的想法。在去除纹身的多种方法中,激光去除是最成功的程序,色素去除程度最高且并发症风险最低。本研究记录了三名纹身患者的情况,仅去除了黑色色素。所有参与的患者均无皮肤过敏、皮肤癌和/或瘢痕疙瘩形成的病史。病例1在右小腿部位分两次去除了专业纹身。病例2在头皮上分三次去除了业余纹身。最后,病例3有两处专业纹身,共分十一次从面部去除。使用了以下设备:脉宽为5纳秒的Spectra XT调Q钕:钇铝石榴石1064纳米激光;脉宽为300皮秒的Pico Ultra 300钕:钇铝石榴石1064纳米激光;以及脉宽为17纳秒的SoftLight调Q钕:钇铝石榴石1064纳米激光。总体而言,取得了满意的效果,但病例1和病例3出现了色素减退。这可能分别是由于激光去除部位的阳光照射、治疗间隔时间短和/或辐射暴露量较高且光斑尺寸较小所致。为了在较高肤色类型中成功去除纹身并减少不良影响,专业人员必须了解要使用的最佳参数,以及基于每位患者和纹身的个体特征的充分依据。此外,患者遵守治疗前/后的护理以及激光治疗之间的适当间隔对于避免不良并发症至关重要。
