Abstract

Odontogenic maxillary sinusitis is predominantly a unilateral maxillary sinus lesion. On examination, a purulent nasal discharge in the middle meatus that occurs unilaterally can be observed. A cone-beam CT can be used to confirm a unilateral maxillary sinus lesion. In this study, periapical lucency, oroantral fistula, aberration of dental material to the maxillary sinus, and aberration of implant tip to the maxillary sinus revealed by CT were diagnosed as odontogenic maxillary sinusitis. In each reported case, pus was aspirated and aerobic and anaerobic cultures were performed.
