Update on Hypertrophic Scar Management in Burn Patients

Hypertrophic scars arise from burn injuries because of persistent inflammation in the reticular dermis. Several risk factors promote this chronic inflammation. One is tension on the burn wound/scar due to surrounding skin tightness and bodily movements. High estrogen levels and hypertension are also important systemic risk factors. Thus, to prevent burn wounds from developing into hypertrophic scars, it is important to focus on quickly resolving the reticular dermal inflammation. If conservative treatments are not effective and the hypertrophic scar transitions to scar contracture, surgical methods such as Z-plasty, full-thickness skin grafting, and local flaps are often used.
