1. Partially healed socket preservation at site 23
A history of socket preservation is present at site 23. The socket preservation material at the crestal aspect exhibit a slightly heterogeneous distribution. A small dehiscence is noted in the overlying buccal cortical plate. The socket preservation material in the apical portion of the site has healed normally and exhibits a density that is similar to that of the adjacent trabecular bone.
2. Multiple healed socket preservations in maxilla
The socket preservations at sites 14, 17, 25, and 27 have healed normally. The socket preservation material at site 25 exhibits a density that is higher than that of the adjacent trabecular bone. Note that buccolingual atrophy in the anterior maxilla and pneumatization of the bilateral maxillary alveolar processes reduces the bone volume available for implant placement.
4. Chronic sinusitis of the right maxillary sinus
The right maxillary sinus is completely opacified, and the sinus walls are thickened and sclerotic. This appearance suggests the presence of chronic sinusitis. Sinusitis is a contraindication to a sinus lift procedure.
3. Localized mild mucositis in the left maxillary sinus
A localized zone of mild mucositis is present on the lateral wall of the left maxillary sinus. This is a non-significant incidental finding.
Sagittal views of the right maxillary sinus
These sagittal cross-sectional images demonstrate the opacification of the right maxillary sinus, as well as a transverse septum apical to site 17. These findings both will impede a potential sinus lift. Note that the presence of chronic sinusitis is a contraindication to a sinus lift procedure.
Sagittal views of the left maxillary sinus: No impediment for sinus lift surgery
These sagittal cross-sectional images demonstrate the presence of localized mild mucositis within the left maxillary sinus. There are no significant impediments for a sinus lift procedure.
5. Left palatine tonsilloliths
Tonsilloliths are present in the left palatine tonsil. This is an incidental finding with no clinical significance.
6. Calcified stylohyoid ligaments
The stylohyoid ligaments are partially calcified bilaterally. This is an incidental finding with no clinical significance.
7. Multilocular lesion in right greater wing of Sphenoid bone
A multilocular entity is present in the right greater wing of the sphenoid bone. This entity is continuous With the middle cranial fossa, and has not caused any significant expansion of the bone. The external surface of the skull base is intact adjacent to this entity. Based on the position of the entity, its continuity with the middle cranial fossa, and the multilocular appearance, the most likely diagnosis is a vascular entity, such as a central hemangioma, or possibly a prominent arachnoid granulation. Further investigation of the skull base by medical imaging is recommended.
