title: [Nasal polyps. Definitions and development of pathogenesis theory].
abstract: This paper presents definitions and types of classifications of nasal polyps. The precise pathogenesis of nasal polyps is not known, although there are several important factors: chronic and recurrent infection of nasal mucose, abnormal vasomotor response, airflow blockade of the middle meatus and ostia of the paranasal sinuses. Since 1843 several pathogenic theories have been introduced.
