ABSTRACT
BACKGROUND: Acquired bilateral nevus of Ota-like macules (ABNOM) are a common form of hyperpigmentation in Asian populations, characterized by brownish-blue or slate-gray pigmentation in the bilateral malar regions. The purpose of this study was to evaluate the efficacy and complications of a Q-switched (QS) fractional ruby laser in the treatment of ABNOM. METHODS: Forty-four patients with ABNOM treated with a QS fractional ruby laser from January 2014 to February 2016 were enrolled in this study. Patients received up to 10 treatment sessions, at intervals ranging from 3 to 4 weeks. An automatic skin diagnosis system was used before and after laser treatment to evaluate the efficacy of the laser treatment. To evaluate the complications of the laser treatment, a retrospective chart review was conducted. RESULTS: Forty-one patients were female, and 3 were male. The mean age of the patients was 47.2 years, and the mean follow-up period was 14 months. The median skin pigmentation score was 5 (interquartile range [IQR], 5–6) before laser treatment and 3 (IQR, 3–4) after laser treatment. A statistically significant difference (P < 0.01) was found in the skin pigmentation score before and after laser treatment. CONCLUSIONS: This study suggests that, although multiple sessions are required, QS ruby fractional lasers can be considered an effective and less invasive form of treatment of ABNOM.
