Abstract
BACKGROUND
Melanocyte-keratinocyte transplant procedure (MKTP) or non-cultured epidermal cell suspension transplantation is a very popular surgical modality for treating stable vitiligo. The recipient-site preparation is one potential determinant in the repigmentation outcomes.
AIM
To assess the efficacy of fractional CO2 (FCO2 ) laser in recipient-site preparation before MKTP and comparing it to the frequently used full surface laser ablation.
METHODS
This randomized comparative trial included 19 patients with 40 stable vitiligo lesions. In each patient, the treated sites were randomly categorized into two groups according to the recipient-site ablation (either fractional or full ablative CO2 laser). Assessment of repigmentation was performed six months after the procedure.
RESULTS
Both modalities achieved successful repigmentation of a median of 80% and 77.5% for fractional and full ablation groups, respectively, with a non-statistically significant difference between them. The median of VASI change percent was -73% and -71% with fractional and full surface ablation, respectively.
CONCLUSIONS
FCO2 laser ablation is effective for recipient-site preparation before cell suspension transplantation as well as the full ablative CO2 laser.
