[Classification of rhinosinusitis].

Rhinosinusitis is a multifactorial disease which has been variously defined by far. There is a strong need among all physicians to create a commonly accepted classification of rhinosinusitis, providing indications for an appropriate evaluation, diagnosis and treatment of the disease. The goal of this review is to present leading definitions of different forms of rhinosinusitis as well as classifications based on clinical findings, temporal considerations and the patophysiology of rhinosinusitis.
