(12) On normal sagittal oblique closed-mouth images, a commonly cited standard for normal disc position on MRI is visualization of the posterior margin of the posterior band at an 11:00 position or more posterior clock-face position above the mandibular condyle
. (13) This margin will be seen anterior to this in the setting of anterior displacement; if present, the degree of displacement is identified on open-mouth imaging.
When the mouth opens, the head of the mandibular condyle
should not pass beyond the apex of the TMJ.
3 and 4 respectively) presented the following effects: deformation of the mandibular condyle
and articular tubercle; bone sclerosis; altered dimensions in the condyle (vertical or latero-medial); cortical erosion; presence of osteophytes; presence of subchondral cyst.
Regarding the first issue, the TMJ is a ginglymoarthrodial joint comprising the mandibular condyle
that articulates with the glenoid fossa of the temporal bone .
All measurements of the mandibular condyle
were made twice with 5-min intervals for six randomly selected subjects.

The article highlights the importance of routinely reviewing the mandibular condyle
on computerised tomography brain studies in a trauma setting.
The TMJ is a ginglymoarthrodial (hinge and glide) articulation with some degree of diathrosis (free motion) formed by the mandibular condyle
and glenoid fossa of the temporal bone (4) (Figure 1).
