Customized negative pressure wound therapy for intractable auricular defects using alginate dressings and feeding tubes

Abstract

Negative pressure wound therapy (NPWT) is a treatment modality that has proven to be useful for complex wounds.1,2 Delivery to the wound is influenced by the negative pressure, the wound filler, and the wound contact layer.3 Recently, portable NPWT systems have been developed, such as the PICO™ (Smith & Nephew Medical Ltd, Hull, UK), V.A.C. Via™ and Prevena™ (Kinetic Concepts Inc, San Antonio, TX), SNaP® (Spiracur Inc., Sunnyvale, CA), and Avance® Solo (Mölnlycke Health Care, Gothernburg, Sweden).
