众所周知， Q-switched Nd:YAG 激光可以有效治疗太田痣和类似病症。我们进行了一项研究，看看 high-fluence 1064 nm Q-switched Nd:YAG 激光对异常区域的蒙古斑的效果如何，并且不会导致皮肤变亮。我们研究了 61 名有这些斑点的患者，总共检查了 70 个病变。一半的病变接受了激光治疗，而其他病变则未进行治疗以进行比较。我们使用体重秤和名为 Mexameter® 的设备来测量黑色素水平来评估结果。治疗组患者平均随访14个月，观察组患者平均随访18个月。在研究结束时，我们发现治疗组和未治疗组之间的量表评分和黑色素水平存在显着差异，激光治疗组显示出更好的结果。 high-fluence Q-switched Nd:YAG 激光不会引起皮肤变亮，事实证明对于治疗这些不寻常的蒙古斑是有效且安全的。
The Q-switched Nd:YAG laser is known to effectively treat nevus of Ota and similar conditions. We conducted a study to see how well a high-fluence 1064 nm Q-switched Nd:YAG laser worked on Mongolian spots in unusual areas, without causing the skin to lighten. We studied 61 patients with these spots, examining a total of 70 lesions. Half of lesions were treated with the laser, while others were left untreated for comparison. We evaluated the results using a scale and a device called a Mexameter® to measure melanin levels. Patients were followed up for an average of 14 months in the treatment group and 18 months in the observation group. At the end of the study, we found significant differences in the scale scores and melanin levels between the treated and untreated groups, with the laser-treated group showing better outcomes. The high-fluence Q-switched Nd:YAG laser, without causing skin lightening, proved effective and safe for treating these unusual Mongolian spots.

我们研究了使用特定激光治疗 ABNOM 的有效性和安全性，并研究了哪些因素可能会影响其效果。我们研究了 110 名患有 ABNOM 并接受了 2 到 9 次激光治疗的患者。我们发现治疗时间越长，效果越好，但对于老年患者效果不佳。对于皮肤颜色较浅（III 型）和受影响区域较小（小于 10 cm2）的患者也效果更好。患有黄褐斑和 ABNOM 使治疗效果较差。受影响区域的颜色或数量似乎没有什么区别。大约10%的患者在治疗后出现黑斑。早期多次治疗取得了良好的效果。皮肤颜色较深、斑点较深的老年患者在治疗后更有可能出现较黑的斑点。对于 ABNOM 兼黄褐斑的患者，最好使用较低能量的激光，以免使黄褐斑变得更严重。
To evaluate the efficacy and safety of 1064-nm Q-switched Nd:YAG laser (QSNYL) therapy for ABNOM and to identify the factors influencing the outcome. A total of 110 patients with ABNOM were retrospectively evaluated and received two-to-nine treatment sessions. The curative effect was positively correlated with the treatment time and negatively correlated with the increasing age at first treatment (p < 0.05). The curative effect was better in patients with skin type III than those with type IV ( p < 0.05) and in patients with a lesion area of less than 10 cm2 than those with a larger affected area (p < 0.05). Additionally, the treatment effect was poorer in patients with concomitant melasma (p < 0.05). The treatment effect was not significantly correlated with the lesion color or number of affected sites (p > 0.05). Eleven patients (10%) developed postinflammatory hyperpigmentation (PIH). Early and repeated QSNYL therapy achieved satisfactory results for ABNOM. The risk of PIH after laser treatment is highest among patients with older age, darker lesion color, and darker skin color. For patients with ABNOM with concurrent melasma, low-energy laser therapy is recommended to reduce the risk of melasma aggravation.

○ 治疗
美白剂很少有帮助。与黄褐斑不同，ABNOM 可以通过激光治疗得到改善，并且可以去除而不会复发。激光治疗可进行 10 至 20 次来治疗 ABNOM。
