One of the critical sites of the thermal injuries is the region of the perineum. Burns of the perineum are relatively frequent, while affections of the anus and sphincters are rare. At the Prague Burns Centre, University Hospital Královské Vinohrady, two patients were treated with this kind of injury. The site of the burns proved in both instances decisive for treatment and for subsequent prognosis. The surgical procedures (necrectomy and autotransplantation) had to be prepared with regard to the case-histories: in the 11-year-old boy by colostomy and in the adult man suffering from muscular dystrophy by a synthetic low-residue diet.
