Temporomandibular joints (TMJ)
Region of interest
[Only visible to logged-in users]
Normal TMJs in mandibular closed position
In the mandibular closed position, both condylar heads are positioned centrally within the glenoid fossae. This is normal. No signs of osseous degeneration are present in the temporomandibular joints.
Normal TMJs in mandibular open position
In the mandibular open position, both condylar heads are positioned at the crests of their respective articular eminences. This is normal.
Normal cervical vertebrae
The cervical vertebrae that are visible in the field of view (C1-C4) appear normal radiographically. No signs of osseous degeneration are present. No abnormal curvatures are present.
Orthogonal measurements of airway
These orthogonal cross-sectional images demonstrate the dimensions of the airway at various levels. No significant constrictions are present.
Clear maxillary sinuses
The maxillary sinuses are clear. No signs of sinus pathology are present.
Normal nasal cavity
The nasal cavity appears patent and normal. No constrictions are evident. No pathology is present.
Normal frontal, ethmoid, and sphenoid sinuses
The frontal, ethmoid, and sphenoid sinuses are clear and exhibit normal osseous contours. No pathology is evident.
This submentovertex reconstruction demonstrates relative alignment of the dental midlines with the midsagittal plane.
PA cephalometric reconstruction
This posteroanterior cephalometric reconstruction from CBCT data demonstrates mediolateral symmetry of the maxilla and mandible relative to the midsagittal plane.
Lateral cephalometric reconstruction from CBCT data
This lateral cephalometric image was reconstructed from CBCT data. The slight anteroposterior asymmetry between the posterior borders of the rami appears to be a result of slight rotation of the patient's head at the time of imaging.
1. Physiologic intracranial calcifications
Parasagittal physiologic calcifications are present intracranially. This is an incidental finding with no significance.
2. Calcified stylohyoid ligaments
The stylohyoid ligaments are partially calcified bilaterally. This is an incidental finding with no clinical significance.
3. Calcified cornu of thyroid cartilage
The right cornu of the thyroid cartilage is partially calcified. This is an incidental finding with no clinical significance.
