Аннотация
BACKGROUND: Various treatments of xanthelasma palpebrarum have been studied, including surgical excision, treatment with chemicals, and ablative laser therapy, but these methods have some disadvantages. Recently, nonablative laser therapy has been proposed as a treatment for xanthelasma palpebrarum.
OBJECTIVE: To investigate the efficacy and safety of a 1,450-nm-diode laser in the treatment of xanthelasma.
MATERIALS AND METHODS: Sixteen patients were treated using a 1,450-nm-diode laser. Fluences of 12 J/cm(2) , a 6-mm spot size, and a dynamic cooling device setting of 20 to 30 ms were used. One to four treatments 4 to 6 weeks apart were given to each patient. Photographs were taken before each treatment session and 4 to 6 weeks after the last treatment.
RESULTS: Two (12.5%), eight (50%), and four (25%) of the 16 patients were scored as having some (20-40% clearing), moderate (40-60% clearing), and marked (60-80% clearing) improvement, respectively. Focal mild transient hyperpigmentation was noted in five patients. Post-treatment local swelling lasted 3 to 4 days.
CONCLUSION: The 1,450-nm-diode laser treatment is a new, valuable treatment option for xanthelasma palpebrarum, offering relatively mild side effects. Studies including long term follow up and a comparison with alternative treatment modalities are necessary to further assess the clinical utility of this treatment. The authors have indicated no significant interest with commercial supporters.
