Maxillary antrolith - an incidental radiographic finding

Abstract

Maxillary antrolith are calcified masses found within the maxillary sinus. The pathogenesis of antrolith formation is not clearly understood, but long-standing and fungal infections, poor sinus drainage, and the presence of foreign bodies are predisposing factors. These calcified bodies are usually discovered on routine panoramic radiographs, although this modality does not stand as the golden-pattern for maxillary antrolith diagnosis. Cone Beam Computed Tomography (CBCT) is known to be an effective method of identifying sinus opacification, and can give valuable information on maxillary sinus inflammation without excessive radiation exposure. The objective of this study was to perform a literature review on antrolith and to report a clinical case of maxillary antrolith discovered on the routine panoramic radiograph on a 56-year-old male patient.
