BACKGROUND: Various surgical modalities and transplantation techniques had been evolved for the treatment of recalcitrant stable vitiligo. Each of these techniques has its own limitations and side effects. There are insufficient studies evaluating the efficacy of transplantation of hair follicle (HF) units as a surgical modality for vitiligo treatment in comparison with the classic mini-punch grafting.
OBJECTIVES: To compare the efficacy and safety of follicular unit transplantation (FUT) with mini-punch grafting (mPG) in cases of resistant and stable vitiligo.
METHODS: Twenty-five patients with stable vitiligo were included. Treated areas were classified into 2 groups: group I: Areas were treated with the FUT technique and group II: Areas were treated with mPG technique. Treated areas were exposed to narrowband ultraviolet B phototherapy for 6 months. After 3 months, follow-up patients' response was evaluated clinically and by dermoscopy.
RESULTS: Both techniques showed efficacy in repigmentation of stable vitiligo. Group II showed a statistically significant higher percentage of repigmentation and significant earlier repigmentation than group I. Cobblestone-like appearance was the major complication in group II, while no serious side effect was reported in group I. Leukotrichia was present in 8 patients, and 6 of them showed hair repigmentation evidently in group I.
CONCLUSION: Both techniques are effective, safe, and inexpensive methods of surgical repigmentation of stable localized/segmental vitiligo. mPG gives earlier and better percent of repigmentation, with higher incidence of cobblestoning. FUT is a good alternative for mPG, especially in hairy areas with better cosmetic outcome and minimal complications.
