• The objective of this study was to evaluate the prevalence and potential clinical significance of incidental sinonasal findings in cone beam computed tomography (CBCT) scans requested for TMJ diagnostic purposes. This project comprised the retrospective analysis of CBCT images from 500 consecutive scans taken with the original purpose of TMD diagnosis. The assessment of potential clinical significance of incidental sinonasal findings was accomplished by the design of a set of guidelines, which may ultimately lead to a better evaluation of incidental sinonasal CT abnormalities by non-sinus specialists. Our results detected incidental sinonasal findings in 84% of the CBCT scans studied, a considerably higher prevalence than previous estimations using random populations studies. Potentially clinically important variables were detected in approximately one fourth of the scans studied, which potentially requires an otolaryngology evaluation.
