Hyperdense findings in sinus computed tomography of chronic rhinosinusitis.

Background: Our study investigated the diagnostic value of the mineralization findings and high-density secretion features of sinus computed tomography (CT) images in cases of chronic rhinosinusitis (CRS) compared to histopathology and operative findings.

Methods: This was a prospective cohort study of 193 patients consecutively enrolled for endoscopic sinus surgery (ESS). Group 1 had mineralization in the sinus; group 2 had high-density secretions in the sinus but no mineralization; group 3 lacked both high-density secretions and evidence of mineralization.

Does chronic rhinosinusitis increase the risk of lung cancer? A population cohort study.

Background And Aims: Chronic rhinosinusitis is one of the most common chronic inflammatory diseases of the upper airway. A previous study of chronic rhinosinusitis and the risks of lung cancer was based on a self-reported questionnaire concerning rhinosinusitis. Population-based cohort studies of the correlation between chronic rhinosinusitis and the adenocarcinoma subtype of lung cancer have been limited.
