1. Oroantral communication at site 26 + acute sinusitis of the left maxillary sinus
An osseous defect within the alveolar process at site 26 extends through the sinus floor. This radiographic appearance reflects an oroantral communication at site 26. The left maxillary sinus demonstrates near complete opacification, but the sinus walls do not demonstrate evidence of chronic changes. This suggests the presence of acute sinusitis secondary to the oroantral communication.
Orthogonal measurements of oroantral defect
These orthogonal cross-sectional images demonstrate the dimensions of the oroantral defect at site 26 from various perspectives.
Orthogonal views of left maxillary sinus
These orthogonal cross-sectional images demonstrate the presence of near-complete opacification of the left maxillary sinus. This appearance suggests the presence of acute sinusitis, which may be secondary to the oroantral communication at site 26.
