Odontogenic sinusitis: a comprehensive review

Abstract

Odontogenic sinusitis (OS) is a highly prevalent, underappreciated and underdiagnosed disease that has been known for over 100 years. Apical periodontitis, periodontal disease and iatrogenic extrusion of foreign bodies into the sinus are the main causes of OS. Although the prevalence of sinus pathosis of dental origin is still controversial, otolaryngologists recognize that in the presence of recalcitrant sinusitis, a dental origin should be considered and properly treated. Currently, cone-beam computed tomography is the gold-standard imaging technique to assess the relationship between dental conditions, especially apical periodontitis and sinus diseases, and whenever this association is detected, patients should be seen by both a dentist and an otolaryngologist in order to achieve complete recovery. This article reviews the current concepts regarding the definitions, diagnosis and management of OS from a clinical point of view.
