References眾所周知，Q‑switched Nd:YAG 雷射可有效治療太田痣及類似病變。我們進行了一項研究，評估 high‑fluence 1064 nm Q‑switched Nd:YAG 雷射對異常區域蒙古斑的效果，並觀察其是否會導致皮膚變亮。研究納入 61 位有此類斑點的患者，共檢查 70 個病灶。其中一半病灶接受雷射治療，另一半作為對照未接受治療。我們使用體重計及 Mexameter® 測量黑色素水平，以評估治療結果。治療組患者平均追蹤 14 個月，對照組平均追蹤 18 個月。研究結束時，治療組與未治療組在量表評分及黑色素水平上皆呈顯著差異，雷射治療組顯示較佳結果。結果顯示，high‑fluence Q‑switched Nd:YAG 雷射不會引起皮膚變亮，證實其對治療這些不尋常的蒙古斑既有效又安全。
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 的有效性與安全性，並探討哪些因素可能影響其療效。研究對象為 110 名患有 ABNOM、接受 2 至 9 次雷射治療的患者。結果顯示，治療次數越多，效果越佳；但在老年患者中效果較差。皮膚較淺（III 型）且受累區域小於 10 cm² 的患者亦獲得較好結果。合併黃褐斑的 ABNOM 患者療效較差。受累區域的顏色或數量似乎無顯著差異。約 10% 的患者在治療後出現黑斑。早期多次治療可取得良好效果。皮膚較深、斑點較深的老年患者治療後較易出現較深的黑斑。對於同時罹患 ABNOM 與黃褐斑的患者，建議使用較低能量的雷射，以免加重黃褐斑。
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
美白劑的效果有限。不同於黃褐斑，ABNOM 可透過雷射治療改善，且在去除後不易復發。雷射治療通常需要 10 至 20 次才能達到理想效果。
