Fracture of glenoid fossa following mandibular trauma

A case of glenoid fossa fracture secondary to mandibular trauma is reported. Subjectively, this injury is characterized by pain in the temporomandibular region of the injured side and by mandibular function impotence. Objectively, there is disappearance of the mandibular condyle from the pretragic region, mandibular lateral deviation toward the fractured side, and premature occlusal contacts on the injured side. The injury can be definitively diagnosed only with a temporomandibular joint radiographic examination of them, which includes a lateral and front-back projection stratigraphy. The surgical techniques currently used in these cases are also discussed.
