All of the above.

Using the diagnostic web viewer, we have provided images that assist in telling our clinical story. Areas of significance are indicated below.

FINDINGS:

Right closed mouth data sets demonstrate an anteriorly positioned malformed or bulbous disc. Open mouth data sets fail to demonstrate disc recapture, and the disc is displaced anteriorly. Sclerosis is present within the condylar eminence. No stress injury. 

The left disc is displaced anteriorly on the closed mouth data sets but does recapture although is malformed on open mouth data sets consistent with partial internal derangement. No substantive arthropathy. 

IMPRESSION:

High grade internal derangement on the right. The disc is globular, anteriorly positioned and does not recapture on open mouth data sets. 

Partial internal derangement on the left includes an anteriorly positioned disc which does recapture.
