title: Chronic rhinosinusitis: relationship between the time of illness, extent of the disease process and results of surgical treatment.
abstract: The object of this study was to determine the relationship between the extent of the disease in the paranasal sinuses and the time of illness. The study included a group of 158 patients treated surgically because of CRS. The evaluation of the extent of the disease process was done according to Kennedy's classification. Statistical correlation between the time of the illness and the extent of the disease process was observed. It was shown that in the group of patients where the disease process was longer than 3 years, changes due to the disease were present on both sides in the ethmoid and dependent sinuses. A relationship was also proved between the time of the illness and the results of the surgical treatment. The patients having had the illness for less than 3 years had a complete recovery rate of 83%. However, those who were ill for over 3 years had only a 49% complete recovery rate.
