IntroductionAnal fissure is described as a linear defect, or laceration, in the anoderm, located between the dentate line and the anal verge. An acute fissure is a simple laceration, whereas a chronic anal fissure is an ulceration with built-up scarred edges and exposed internal anal sphincter muscle fibers at its base. Additional findings may include a perianal skin tag at the external margin of the fissure and a hypertrophied papilla at the dentate.
