35-year-old female patient with right-sided ear and facial pain. Evaluate for TMJ pathology. The anterior band of the right temporomandibular joint disc is abnormally thickened with increased signal intensity likely representing degeneration and tearing. The disc as a whole appears slightly anteriorly displaced relative to the left side. There is anterior translation of the mandibular condyle on the open mouth views that appears normal on the left and slightly decreased on the right. On the open-mouth view, the anterior band again appears enlarged with abnormal signal intensity representing degeneration and tearing with the posterior band appearing abnormally small. We see no erosive changes of the bones or large effusion.
Degeneration and tearing of the articular disc of the right temporomandibular joint with other findings as described above.
