1. Antrolith in left maxillary sinus: ENT referral recommended
A well-defined, irregularly shaped radiopacity with a densely corticated periphery and a granular internal appearance is present within the left maxillary sinus. This radiopacity is positioned along the medial sinus wall at the level of the middle nasal meatus, and closely abuts the osteomeatal complex. The radiographic appearance is most suggestive of a large antrolith within the left maxillary sinus. While this is typically a non-significant incidental finding, the large size and position of this antrolith has resulted in obstruction of antral drainage and chronic sinusitis, which suggests that referral to an ENT specialist is indicated for further management.
2. Chronic sinusitis of the left maxillary sinus
The left maxillary sinus is opacified, and the sinus walls are thickened and sclerotic. This appearance suggests the presence of chronic sinusitis, which may be secondary to the large antrolith that has obstructed antral drainage.
Orthogonal measurements of antrolith
These orthogonal cross-sectional images demonstrate the approximate dimensions of the antrolith in the left maxillary sinus.
Periodontal bone loss + calculus
Generalized severe periodontal bone loss and calculus deposition are evident on the remaining maxillary teeth.
3. Mild mucositis in the right maxillary sinus
Mild mucositis is present in the right maxillary sinus. This represents an incidental finding with no clinical significance.
4. Ethmoid sinus mucositis
The ethmoid air cells demonstrate mucosal thickening, which reflects the presence of mild mucositis.
5. Intracranial calcification of internal carotid arteries
Calcifications are visible lining the walls of the cavernous segments of the right and left internal carotid arteries. These findings may represent signs of arteriosclerosis. The significance of this finding cannot be determined based on CBCT imaging alone.
