Abstract

Objectives: To evaluate the efficacy and safety of Q-switched ruby laser (QSRL) for Chinese patients with acquired bilateral naevus of Ota-like macules (ABNOM). Methods: Thirty Chinese female patients were enrolled. QSRL therapy was performed at intervals of three to six months, with the following parameters: spot size, 6 mm; pulse duration, 20 ns; fluence, 2.5-3.5 J/cm2. Results: Twenty-six patients achieved good to excellent clearance after one to seven (mean 3.2) treatments. Repeated treatments led to enhanced efficacy. Nine developed transient post-laser hyperpigmentation while two developed persistent hypopigmentation. Conclusions: QSRL provides a safe, effective and economical treatment modality for ABNOM in Chinese.

目的:評價Q開關紅寶石激光對華人後天對稱性太田痣樣斑的治療成效和安全性。方法:有三十個中國女性患者參加。以以下參數,每隔三至六個月內進行Q開關紅寶石激光治療:光點大小6毫米;脈衝持續時間,20納秒;流量2.5-3.5焦耳/平方厘米。結果:經過一至七次(平均3.2)治療後,二十六例患者獲得好至極好的療效。多次治療可提高療效。九例患者出現短暫色素沈著,兩例出現持久性色素減退。結論:Q開關紅寶石激光是治療後天對稱性太田痣樣斑的一種安全 、有效及經濟的方案。
