BACKGROUND AND OBJECTIVE
The term, labial melanotic macule, refers to a benign entity. The Q-switched ruby laser (QSRL) has been used to treat such lesions but the numbers are small with relatively short follow-up.
STUDY DESIGN/MATERIALS AND METHODS: Eight patients were treated with single pulses of the QSRL (694 nm, 20 nsec pulse duration, and 5 mm spot size) at 6.5 J/cm(2). Patients were followed-up for a maximum of 24 months to assess for recurrence.
RESULTS
Five patients cleared with a single pulse of the QSRL, while three required a second treatment session. There were no side-effects reported. At follow-up, there was no recurrence of pigment.
CONCLUSIONS
Treatment of labial melanotic macules with the QSRL produces excellent cosmetic results. No new pigment was detected at follow-up.
背景与目的
术语“唇部黑素沉着斑”指的是一种良性病变。调Q红宝石激光（QSRL）已被用于治疗此类病变，但相关病例数量较少且随访时间相对较短。
研究设计/材料与方法：8例患者接受了波长694nm、脉冲持续时间20纳秒、光斑大小5mm的QSRL单脉冲治疗，能量密度为6.5J/cm²。对患者进行了最长24个月的随访以评估复发情况。
结果
5例患者经QSRL单脉冲治疗后色素消退，3例患者需要接受第二次治疗。未报告有副作用。随访时，色素未复发。
结论
用QSRL治疗唇部黑素沉着斑可产生极佳的美容效果。随访时未检测到新的色素沉着。
