Brief Summary:
ORSHFS grafts yielded lower cell counts than NCECS but the M-K ratio and resultant repigmentation did not show significant difference with better healing of the donor site. Compared to cryoblebs, CO2 gave more homogenous pigmentation. The acral sites showed better results using combination of donor NCECS and recipient cryoblebs.
Detailed Description:
Background: Melanocyte-keratinocyte suspension (M-K susp) is gaining popularity for vitiligo treatment. Few studies have addressed procedure-related variables.
Objective: To assess the effect of different M-K susp procedure-related variables on the clinical outcome in stable vitiligo.
Methods: This retrospective study included 40 cases with stable non-segmental vitiligo treated by M-K susp followed by narrow band- ultraviolet B phototherapy twice weekly. Donor site was either a skin graft in non-cultured epidermal cell suspension (NCECS) (34 cases) or hair follicle unit in Outer Root Sheath Hair Follicle Suspension (ORSHFS) (6 cases). Recipient site was prepared by either cryoblebbing (24 cases) or carbon dioxide (CO2)laser resurfacing (16 cases). Cell counts and viability were recorded in the cell suspensions, and tissue melanocytes and keratinocytes were examined by Melan A and Cytokeratin respectively. Assessment of repigmentation was done 18 months after the procedure.
