Odontogenic maxillary sinusitis identified by coronal view of paranasal sinus computed tomography. (A) Periapical lucency in left maxillary sinus floor. (B) endodontic-maxillary erosion in left maxillary sinus. (C) Implant protrusion into the left maxillary sinus. The distance between the post of greatest protrusion (a) and the inner bony cortical lining of the maxillary sinus (b) was measured to determine the length of the implant extrusion into the maxillary sinus.
