Intrusion of the mandibular condyle into the middle cranial fossa: report of a case in an 11-year-old girl.

Intrusion of the head of the condyle into the middle cranial fossa is a rare but highly significant result of trauma to the mandible. Various treatment modalities for this type of injury have been reported in the literature. This case report concerns the intrusion of the left mandibular condyle into the middle cranial fossa in an 11-year-old girl. Five days after the original injury, severe limitation of opening was noted, as was a significant overjet and posterior open bite. A CT scan revealed intrusion of the left condyle into the middle cranial fossa. Treatment consisted of closed reduction with intermaxillary fixation. At the 10-month follow-up, full range of motion was possible with only minimal deviation.

Total temporomandibular joint replacement in a patient with rheumatoid arthritis: report of case.

This case is an example of a patient with apparent successful total TMJ replacement. With reconstruction of the joints with artificial implants, the loss of posterior ramus height because of complete erosion of the joints, mandibular retrognathia, and severe open bite were corrected. The improved masticatory function, absence of choking, and disappearance of sleep apnea symptoms allowed the patient to resume a more normal life. The patient will continue to be examined periodically, but the current prognosis is favorable.
