title: Maxillary sinus morphology in differential dental diagnosis.
abstract: In this case, the shape of the maxillary sinus was misinterpreted as a periapical pathological condition. Based on this anatomic misinterpretation, conventional endodontic therapy had been performed on two teeth. When the suspected lesion did not resolve, an exploratory procedure revealed the unusual morphology of an otherwise normal maxillary sinus. The anatomy and morphology of the maxillary sinus in differential dental diagnosis are discussed, and surgical exploration is demonstrated. A case of healthy sinus anatomy with abnormal morphology is reported.
