RESUMO
Objective To evaluate the efficacy of the autologous epidermal grafting combining with NB-UVB radiation on the treatment of stable vitiligo.Methods Autologous epidermal graft acquired by suction blister under negative pressure were transplanted onto the laser-abraded depigmented areas,then the narrow-band UVB radiation was given after grafting to 35 patients with stable vitiligo.The onset time and the area repigmentation of every epidermal graft 3 months latter were observed (digital image contrasted before and after treatment).The results were compared with 37 cases only treated with autologous epidermal grafting.Results Both onset time and the cure rate in combined treatment group were statistically significant (P＜0.05) as compared with control group.Conclusions The combination of autologous epidermal grafting with NB-UVB radiation can shorten the onset time of repigmentation and promote generation and extension of the melanin.
