A retrospective analysis of 100 coronal sinus CT scans was performed to investigate the frequency of opacity of the nasolacrimal duct and determine if there was any correlation between the pattern of duct opacity and the presence of inflammatory sinus disease. The study showed that the nasolacrimal ducts are opaque in the majority of normal people and that there is no relationship to inflammatory sinus disease.
