While there are several definitions of chronic or nonhealing wounds β and it is generally accepted that under normal circumstances, wound healing occurs within 6 weeks of injury and wounds that fall outside that are generally referred to as chronic wounds β the same cannot be said for burn wounds.
We know that a superficial burn will heal in 5β7 days and a superficial dermal burn within 7β10 days, but little is understood about the normal healing trajectory of deep dermal or full-thickness burns.
