During routine panoramic radiographic examinations, a series of incidental findings may be observed in maxillary sinuses. One of these findings may be exostoses which are the outgrowths of compact and cancellous bone. In this case report, we represent two cases of exostosis of the maxillary sinus evaluated using cone-beam computed tomography. Although antral exostoses have no clinical importance, except if they cause obstruction of sinus ostium, their differential diagnosis must be achieved from other pathologies with similar radiographic properties such as anthroliths and osteomas.
