Uncommonly, an open lock can occur when the mandibular condyle
is unable to translate back into the glenoid fossa, whether due to posteriorly displaced disc material or due to the articular eminence (Figure 4).
The mass was centered on the temporomandibular joint, and it had eroded the lateral margin of the mandibular condyle
. The radiologic differential diagnosis included pigmented villonodular synovitis, synovial sarcoma, chondroma, osteochondroma, or a parotid lesion.
Radiographs revealed the left zygomatic fossa devoid of the mandibular condyle
without visible fracture (Figure 1).
The mean value in the coronal section of the mandibular condyle
in the control group was 4.2 mm.
ID refers to an abnormal positional relationship of the articular disc in relation to the mandibular condyle
and the articular eminence in the glenoid fossa, in the temporal bone [5, 10, 11, 14].
The area, perimeter, width, and height of the mandibular condyle
were measured using the image analysis AutoCAD software (AutoCAD, Autodesk Inc.; San Rafael, CA), and their values were compared among groups.
The morphology of the articular eminence, glenoid fossa and mandibular condyle
depends on numerous factors, such as changes in dentition associated with aging (tooth loss, attrition and/or increased function), degenerative changes of the glenoid fossa, masticatory stress, craniofacial growth, gender, ethnicity and the relationship between the fossa and the eminence in relation to the facial structures(4,6,10-13).
Recurrent simple bone cyst of the mandibular condyle

A clinical investigation on disc displacement in sagittal fracture of the mandibular condyle
and its association with TMJ ankylosis development.
An active mandibular condyle
with a related, progressing facial deformity often requires high partial condylectomy to limit the growth of the condyle.
The main components of the TMJ are the mandibular condyle
, the mandibular fossa of the temporal bone, the articular disc with collagen fibers interposed with between them, and a synovial [1-5].
Based on the results of the current study, all protocols proposed have proved suitable for the identification of cavitary defects in the superior surface of the mandibular condyle
. However, the protocol of a 1.0 mm-thick slice and no filter proved to be the worst for identifying the defects on the posterior surface.
The patient had undergone a surgery for her TMJ ankylosis of the right side of mandibular condyle
but her mouth opening was still just 10 mm.
