J. Flinn et al., A PROSPECTIVE ANALYSIS OF INCIDENTAL PARANASAL SINUS ABNORMALITIES ONCT HEAD SCANS, Clinical otolaryngology and allied sciences, 19(4), 1994, pp. 287-289
A prospective analysis of the incidence of paranasal sinus opacificati
on in 100 patients referred for cranial computerized tomography (CT) f
or non-sinus related problems is described. The findings were correlat
ed with symptomatic assessment. Twenty-seven per cent of asymptomatic
patients had sinus opacification. The study illustrates the importance
of careful clinical correlation when interpreting CT scans of the par
anasal sinuses.
