Abstract:
Odontogenic sinusitis (ODS) has been shown to be the most common cause of unilateral maxillary sinus opacification on computed tomography scans. Review of the maxillary alveolar ridge and maxillary tooth roots, and their relationships to the maxillary sinus floor is essential when interpreting paranasal sinus imaging. In recent years, ODS has received increased attention in the recent otolaryngologic and dental literature. This article will discuss technical considerations to optimize imaging of the paranasal sinuses and maxillary dentition, as well as both classic and nuanced radiologic findings of ODS.
