眾所周知， Q-switched Nd:YAG 雷射可以有效治療太田痣和類似病症。我們進行了一項研究，看看 high-fluence 1064 nm Q-switched Nd:YAG 雷射對異常區域的蒙古斑的效果如何，並且不會導致皮膚變亮。我們研究了 61 位有這些斑點的患者，總共檢查了 70 個病灶。一半的病變接受了雷射治療，而其他病變則未進行治療以進行比較。我們使用體重計和名為 Mexameter® 的設備來測量黑色素水平來評估結果。治療組患者平均追蹤14個月，觀察組患者平均追蹤18個月。在研究結束時，我們發現治療組和未治療組之間的量表評分和黑色素水平有顯著差異，雷射治療組顯示出更好的結果。 high-fluence Q-switched Nd:YAG 雷射不會引起皮膚變亮，事實證明對於治療這些不尋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.

我們研究了使用特定雷射治療 ABNOM 的有效性和安全性，並研究了哪些因素可能會影響其效果。我們研究了 110 名患有 ABNOM 並接受了 2 到 9 次雷射治療的患者。我們發現治療時間越長，效果越好，但對於老年患者效果不佳。對於皮膚顏色較淺（III 型）和受影響區域較小（小於 10 cm2）的患者也效果較好。患有黃褐斑和 ABNOM 使治療效果較差。受影響區域的顏色或數量似乎沒有什麼區別。約10%的患者在治療後出現黑斑。早期多次治療取得了良好的效果。皮膚顏色較深、斑點較深的老年患者在治療後更有可能出現較黑的斑點。對於 ABNOM 兼黃褐斑的患者，最好使用較低能量的激光，以免使黃褐斑變得更嚴重。
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.

○ 治療
美白劑很少有幫助。與黃褐斑不同，ABNOM 可以透過雷射治療得到改善，並且可以去除而不會復發。雷射治療可進行 10 至 20 次來治療 ABNOM。
