Efficacy and safety of 308 nm excimer laser for vitiligo / 中国医学科学院学报

ABSTRACT

<p><b>OBJECTIVE</b>To assess the efficacy and safety of the 308 nm excimer laser for the treatment of vitiligo.</p><p><b>METHODS</b>We treated 170 patients with stable vitiligo by using the 308 nm excimer laser. The lesions of vitiligo were treated one to two times per week for 10-30 times. Efficacies were evaluated every 7 days and 3 days after the treatments were completed. Patients were followed up for two months.</p><p><b>RESULTS</b>The rates of "remarkably improved" and "cured" were 67.97% and 32.03% in faces, 54.55% and 27.27% in necks, 63.26% and 26.53% in trunks, 38.84% and 15.70% in limbs, and 0 and 0 in hands and feet. The areas of faces had a better response than those of necks, trunks, or limbs (P < 0.01), and the areas of trunks or limbs had better response than that of hands and feet (P < 0.01).</p><p><b>CONCLUSION</b>The 308 nm excimer laser is safe and effective in treating stable vitiligo and the efficacy varies in different lesion sites.</p>
