The condyles itself looked similar in size and form (Figure 1).
Praeoperative CT scan of the lesion in the right temporomandibular joint.

The full extent of these lesions on the right side was defined more precisely by a computed tomography (CT) scan (Figure 2).
Preoperative MRI. Axial T2-weight slide. Praeoperative lesion surrounding the right temporomandibular joint.

In a separate performed magnetic resonance imaging (MRI), lesions could furthermore be described as a cystical diagnostic finding (Figures 3 -5).
Preoperative MRI: coronal slide, contrast-ehanced T1-weight:cranio-lateral surrounding of the TMJ by the lesion.

Twenty five loose bodies of different size retrieved from the synovial space and the inner TMJ-capsule.

The access was obtained by a right preauricular approach in order to gain enough exposure of the numerous small particles in the temporomandibular region. Twenty five loose bodies of different size were retrieved from the synovial space and interior of the capsule (Figure 6).
Calcified chondral bodies with regressive changings most likely to correlation to a synovial chondromatosis.

This was verified by the microscopic examination which revealed all bodies to be of calcified chondral origin with regressive changings with characteristics most likely of a SC (Figure 7).
