ORTA ANADOLU'DA KRONİK RİNOSİNÜZİTİN BİREYSEL ÖZELLİKLER VE ÇEVRESEL FAKTÖRLERLE İLİŞKİSİ

Abstract

OBJECTIVE: The aims of this study were to investigate the prevalence and distribution of sinonasal diseases in patients that underwent paranasal sinus computed tomography (CT) due to chronic rhinosinusitis (CRS) with or without nasal polyps, and to explore the association between CRS and sinonasal variations and the effect of environmental factors.MATERIAL AND METHODS: The paranasal sinus CT images and files of 1000 patients that referred to a tertiary health center in Ankara were retrospectively evaluated. The CT findings, smoking status, presence of allergies, place of residence (urban/rural), and history of functional endoscopic sinus surgery were noted.RESULTS: CRS was seen in 68% of the patients, and most common in maxillary sinuses (53%). Nasal polyps with CRS were noted in 11% of the cases. CRS was also more common among smokers (p<0.001). In CRS accompanied by nasal polyps, no difference was found between urban and rural residence. However, most cases of CRS with nasal polyps lived in urban areas (81.4%, p=0.006). There was no difference between allergy and CRS with and without nasal polyps or between sinonasal variations and CRS development.CONCLUSIONS: In the region investigated, the prevalence of CRS with nasal polyps was higher in the urban area (higher air pollution); however, the prevalence of CRS without nasal polyps did not change according to the place of residence. CRS was generally more common among smokers, but there was no significant difference in patients with CRS accompanied by nasal polyps. CRS was not more common in people with allergies.
