Mandibular Condyle
The condylar process of the mandible is defined as the portion of the mandible superior to the sigmoid notch and includes the mandibular portion of the temporomandibular joint (TMJ). Condylar fractures are classified as extracapsular, subcondylar, or intracapsular. TMJ dislocation can occur from both directly blunt force and from pulling of the lateral pterygoid muscle on a fractured mandibular condyle. Condylar fractures that extend to the articular surface of the TMJ have can significant morbidity from resultant temporomandibular joint disorder.
Scrollable Stack Images
Images show a fracture of the mandibular condyle on the right. The fracture is transversely orientated at the level of the condylar neck. The fracture does not extend to the articular surface of the condylar head. Anteromedial displacement of the right mandibular condyle in relation to the temporomandibular joint can be appreciated. No additional mandibular fractures are seen.
