Site 26: Inadequate bone
A 5x8mm cylinder was overlaid on the adjacent images at site 26. Inadequate bone exists for this cylinder to be fully embedded at this site due to the presence of a prominent loculation of the nasal cavity.
Site 27: Adequate bone
A 5x8mm cylinder was overlaid on the adjacent images at site 27. Adequate bone exists for implant placement at this site.
Sagittal views of left maxilla
These sagittal cross-sectional images demonstrate the mucositis that is present on the floor of the nasal cavity apical to site 26.
1. Rarefying osteitis on tooth 17MB: Unfilled MB2 canal
Rarefying osteitis is present at the mesiobuccal root apex of tooth 17. This may be secondary to the presence of an unfilled second canal in the mesiobuccal root. The lateral position of the existing obturation within the root of the tooth supports this diagnosis.
2. Retained roots of tooth 27
The roots of tooth 27 are retained. No periapical pathology is present, but furcal bone loss extends to the level of the apical thirds of the roots.
3. Enlarged bone marrow space apical to tooth 36M
An enlarged bone marrow space is present in the apical region of the mesial root of tooth 36. This is a non-significant incidental finding.
4. Hypoplastic maxillary sinuses
The maxillary sinuses are hypoplastic, and are positioned at the posterior superior aspect of the maxilla. Both sinuses are completely opacified, which is suggestive of the presence of mucositis. Due to the small size of the maxillary sinuses, the nasal cavity has extended into the sinus spaces.
5. Wide nasal cavity
The nasal cavity extends laterally into the regions normally occupied by the maxillary sinuses. The nasal cavity overlies the region apical to sites 26 and 27.
Coronal views of maxilla
These coronal cross-sectional images demonstrate the enlarged nasal cavity, as well as the hypoplastic maxillary sinuses that contain mucositis or sinusitis.
Axial views of maxilla
These axial cross-sectional images demonstrate the wide nasal cavity which has extended into the area normally occupied by the maxillary sinuses. Mucositis lines the walls of the nasal cavity.
6. Elongated styloid processes
The styloid processes are elongated bilaterally. This is an incidental finding with no significance.
7. Mild cervical degenerative joint disease
Small osteophytes and mild subchondral sclerosis are present on the articulating surfaces of the cervical vertebrae. This is suggestive of the presence of mild cervical degenerative joint disease, which is an incidental finding with no clinical significance.
