The informed consent leaflet “ChB 10h” provides information on surgical procedures treating pilonidal abscesses and fistulas in the natal cleft overlying the coccyx or the sacrum. These generally occur when an ingrown hair follicle becomes inflamed and infected. Sweating and a sedentary lifestyle can promote infection and pus formation. Pilonidal fistulas occur in particular in persons with strong hair growth, those who ride horses frequently, and truck drivers.
