[Management of hypopigmented scars following burn injuries].

OBJECTIVE

Permanent hypopigmentation of burn scars is a common consequence after partial and full thickness burns that heal by secondary intent, and they can cause severe aesthetic issues. The surgical goals for effective treatment of postburn hypopigmentation are to remove scar tissues, and to produce healthy melanocytes, with minimal donor site morbidity. This article reviews the current literature about the different ways to treat hypopigmentation following burn injuries and discusses the indications.

METHODS

The PubMed database was searched for articles published from 1985 and up to 2016. Papers with regards to the management of hypopigmented lesions were included only if scars were following burn injuries. The treatments were assessed according to body region treated, surface involved, skin color, effectiveness on restoring skin pigmentation.

RESULTS

Sixteen studies were included in this review. Non-surgical treatments like makeup and tattooing, and surgical treatments including thin skin grafting, chip skin grafting, punch grafting, non-cultured keratinocyte-melanocyte cell suspension, and cultured epidermal cells were all compared.

CONCLUSION

Thin skin grafting is a reliable treatment especially for patient who suffer from small hypopigmented lesions as this method requires a donor skin of the same size. The cell suspension procedure may be beneficial for larger scars. Moreover demarcation between skin graft and normal skin may exist and when a precise color match is required, particularly in the head, tattooing and chip skin grafting produce a good pigmentation outcome.
