BACKGROUND: Fractional CO2 laser and autologous hair transplantation are independently effective in the treatment of refractory and stable vitiligo.
OBJECTIVE: The authors' purpose was to evaluate the therapeutic efficacy of fractional CO2 laser pretreatment compared with autologous hair transplantation and phototherapy alone for refractory and stable vitiligo.
METHODS: A total of 20 patients with refractory and stable vitiligo were enrolled from our clinic. Resistant lesions randomly divided into 2 regions as follows: (1) Part A: fractional CO2 laser pretreatment followed by autologous transplantation and phototherapy, and (2) Part B: autologous transplantation and phototherapy alone. Five days after fractional CO2 laser application to Part A, both treatment regions received a transplant of scalp grafts. On Day 11, the entire lesion was exposed to narrow-band UVB phototherapy, twice a week for 12 weeks. The diameter of perifollicular repigmentation was measured monthly with a caliper.
RESULTS: Perifollicular repigmentation was detectable surrounding 74% of grafted hair follicles by Month 3. Furthermore, Part A demonstrated a significantly greater diameter of repigmentation with 6.6 ± 5.8 mm in Part A compared with 4.3 ± 1.8 mm in Part B (p = <.001).
CONCLUSION: In this study, our results demonstrate improved efficacy of autologous hair transplantation and narrow-band UVB with fractional CO2 laser pretreatment in refractory and stable vitiligo.
