[Point scale quantification of changes in computed tomography of chronic hyperplastic rhinosinusitis]

Coronal CT scans have dramatically improved imaging of the nasal cavity and paranasal sinuses. However, quantification of the extent of chronic sinusitis is not possible by simple reviewing of the CT images. The aim of the study was to introduce a CT scoring scale to assess the extend of sinusal pathology. Seventeen patients with clinically recognized aspirin-sensitive rhinosinusitis asthma syndrome (aspirin triad) were studied. The CT scans were reviewed and scored for extent of the disease by two independent radiologists. Repeated readings of the scans showed close correlation between the two assessments. The authors conclude, that CT scoring system for quantitation of the disease extent is reproducible and may be useful in clinical practice.
