Abstract
Background Of all the tissue or cellular grafting techniques used in the treatment of vitiligo, melanocyte transplant/transfer through ultrathin skin grafting (UTSG) provides rapid onset of regimentation. The regimentation process is further accelerated with a combination of psoralen and ultraviolet A radiation, or psoralen and ultraviolet A obtained by sunlight or narrowband ultraviolet light B, or excimer laser/lamp (308 nm). Aims We assessed the efficacy of carbon dioxide laser ablation followed by melanocyte transplant/transfer through ultrathin skin graft sheet/sheets and further treated by excimer lamp therapy in patients with stable vitiligo. Methods One hundred ninety-two patients with stable vitiligo were treated with UTSG following carbon dioxide laser ablation and patients were then put on excimer lamp therapy. Primary efficacy was determined in terms of grades of regimentation and colour match at the end of 1-year. Results A total of 192 stable vitiligo patients with a mean age of 32.71 ± 8.55 years were recruited. Of the total 410 lesions, 394 showed excellent regimentation indicating a success rate of 96.1% at 1-year follow-up, whereas 16 (3.9%) lesions present on fingertips and toe tips showed poor or no regimentation at 3-month and 1-year follow-up. With regards to colour match, 394 (96.1%) lesions had achieved excellent colour match, and 16 lesions (3.9%) had poor or no colour match at 1-year follow-up. Limitations This was a single-center study with a small sample size. Conclusion The effectiveness of carbon dioxide laser ablation followed by melanocyte transfer/transplant through ultra-thin skin graft sheet/sheets when combined with excimer lamp therapy provides favourable cosmetic outcomes with rapid onset of regimentation in stable vitiligo.
