escharectomy

Full Definition

Escharectomy is the surgical excision of dead, leathery tissue that forms over deep burn wounds. This procedure is essential for removing non-viable tissue that can harbor bacteria and prevent healing. It differs from debridement in that it specifically targets the thick, leathery eschar characteristic of full-thickness burns. The procedure must be performed before skin grafting can be successful, as healthy tissue is required for graft adherence.

Usage

Usage note: Often confused with escharotomy, which is an incision through eschar to relieve pressure, not removal of tissue.
