Necrotizing soft tissue infection (NSTI) is a life-threatening illness that can seriously harm a person. Over the last years the incidence of NSTI has increased. A rapid and thorough debridement is crucial to let patients survive. After this debridement, patients will often end up with large skin defects. A burn center is specialized in treating skin defects. Patients with large skin defects after the acute phase of NSTI can be referred to this for a multidisciplinary approach. In this article we describe the surgical treatment of the complex wounds of three referred patients with NSTI in our burn center.
