Region of interest
[Only visible to logged-in users]
Normal TMJs in mandibular closed position
In the mandibular closed position, both condylar heads are centrally positioned in the glenoid fossae. This is normal. No signs of degeneration are present in the articulating regions of the temporomandibular joints.
Normal TMJs in mandibular open position
In the mandibular open position, both condylar heads are positioned at the crests of the articular eminences. This is normal. No signs of reduced range of motion are radiographically evident.
Normal coronoid processes
The coronoid processes appear normal bilaterally. No signs of enlargement of the coronoid processes are present.
1. Small subcutaneous calcification overlying left masseter
A small round subcutaneous calcification overlies the left masseter. This is a non-significant incidental finding.
2. Normal appearances of muscles of mastication
The muscles of mastication appear normal radiographically. No signs of calcification are present.
