title: [Subcondylar mandibular fracture].
abstract: Mandibular fractures are frequent lesions which are classified into 6 groups according to the site of the fracture. Condylar fractures are primarily due to a direct blow to the symphysis menti. Medical imaging must be able to identify the type of fracture, its intra- or extra-articular site and the associated displacement of the condyle, the fundamental element in deciding treatment. The action of the masticatory muscles on one of the bone fragments may be responsible for an unstable fracture, leading to disturbances of consolidation (pseudarthrosis). Anterior bilateral fractures can be life-threatening due to ptosis of the tongue.
