Abstract

Temporomandibular joint (TMJ) dislocation is characterized by mandibular condyle dislocation out of articular cavity, fixated in an abnormal position in which self-reduction it is not possible. The TMJ traumatic dislocation occurs after medium and high intensity trauma directly on the joint or on symphyseal area and it is generally associated to fractures. This report documents a case of an unusual posterolateral dislocation of the left condyle with tympanic plate fracture, insignificant fracture of mandibular condyle, and discuss about the clinical symptoms, classification of dislocations, and treatment. A list of similar cases from the last 10 years is also showed.
