Traumatic dislocation of intact mandibular condyle into middle cranial fossa

Introduction A 10-year-old girl presented to the Emergency Department with temporomandibular joint pain, malocclusion, and trismus after a bicycle accident. Methods CT of the temporal bones showed displacement of the right mandibular condyle into the middle cranial fossa with small intraparenchymal hemorrhage. The condyle was reduced using closed reduction technique and the patient was placed in maxillomandibular fixation. Results Complete reduction of the displaced condyle with resultant normal occlusion and persistent bony defect in the temporal bone. Conclusion In early follow-up assessments the patient has had complete resolution of symptoms with residual bony defect from the site of fracture in the temporal bone.
