Imaging of Trauma and Acquired Conditions of the Temporomandibular Joint

As with any joint of the body, the temporomandibular joint (TMJ) may suffer a traumatic injury. Trauma to the TMJ can precipitate a cascade of changes in the joint which may give rise to patient symptoms. It is essential for the radiologist to be aware of the range of presentations of joint trauma and the sequelae of trauma and various acquired conditions which may be linked to previous traumatic insult of the joint to facilitate early diagnosis and appropriate treatment (if indicated) to hopefully reduce discomfort for the patient and the long-term impact of these conditions.
