- Abstract
Noncultured epidermal cell suspension (NCES) is a well‐established surgical treatment modality for stable vitiligo. The outcome of this procedure significantly depends on the method of recipient site preparation, a critical step to achieve cosmetically acceptable repigmentation. To compare the efficacy of recipient site preparation using three methods namely, dermabrasion, cryoblister, and dermaroller followed by NCES in stable vitiligo. In this single‐center, prospective, intra‐patient, randomized clinical trial; 36 participants having at least three vitiligo patches in same anatomic region with minimum lesional stability of 1 year were randomized 1:1:1 for recipient site preparation using manual dermabrasion, cryoblister, and dermaroller followed by NCES. Patients were followed up at 4, 8, and 12 weeks and assessment of extent and pattern of repigmentation, color match and patient satisfaction were done. Among 36 patients, 22 (61.1%) were females; mean (SD) age was 28.33 (9.4) years. Dermabrasion and cryoblister techniques showed equal efficacy with respect to extent of repigmentation (>75% repigmentation; 55.6% vs 47.2%; P =.63) and patient satisfaction score (20.2 ± 9.6 vs 19.9 ± 7.9, P =.194). However, dermabrasion was superior to cryoblister in terms of rapidity (65% vs 32.5% at 4 weeks, P =.04) and color match (47.2% vs 19.4%, P =.004). Dermaroller had poor repigmentation outcomes compared to both dermabrasion and cryoblister. Cryoblister as a method of recipient site preparation is equally effective as manual dermabrasion in NCES for attaining good to excellent repigmentation, but with risk of hyperpigmentation. However, dermaroller is inferior to both dermabrasion and cryoblister.
