Pathogenesis and Pathophysiology of Nasal Polyps

The pathogenesis of nasal polyps explains how the polyps start and grow. The pathophysiology of nasal polyps explains the events and processes taking place in the outgrowth of nasal polyps. Histopathological studies at various stages of polyp formation, using whole-mount methods, the glands of the uncut polyps and the ordinary histological sections, allow our statements on pathogenesis of nasal polyps. Origin and incidence of nasal polyps on autopsies, studies on the changing epithelium and quantitative studies of the inflammatory cells of the nasal polyps, removed from the patients, allow us some statements on pathophysiology of the nasal polyps. In fact, only the age of the nasal polyps separates the term pathogenesis from the pathophysiology.
