Abstract Background Perineum necrotizing fasciitis. also known as Fournier gangrene (FG). is a rare but highly mortal infectious necrotizing fasciitis with or without involvement of the underlying muscle. Evidence exists that negative pressure wound therapy (NPWT) combined with a split thickness skin graft (STSG) can help to heal wounds with FG. https://allfixelectricales.shop/product-category/sealing-washer-kit/
