Abstract: The structurally weak mandibular condylar neck is more likely to break when subjected to external force. Mandibular condyle fractures can dissipate the traumatic energy, avoiding damage to the middle cranial fossa and other important anatomical structures of the brain, which can be regarded as a self-protection mechanism of the human body. A rare case of traumatic dislocation of the mandibular condyle into the middle cranial fossa was reported in this paper. The patient’s mandibular condyle without fracture was dislocated through the base of the middle cranial fossa into the cranium. The pathogenesis, clinical manifestations, diagnosis and treatment for intracranial dislocation of mandibular condyle were discussed with review of relative literatures.

Key words: Mandibular condyle, Intracranial dislocation, Treatment
