Three cases of TMJ ankylosis due to mandibular fracture were treated successfully by surgery that involved aggressive resection of the ankylotic segment and insertion of a silicon sheet implant.<BR>Case 1 was a 37-year-old male who had fallen down and suffered fracture of the lower limbs and mandible at the age of 25. Fractur of the anterior part of the mandible was treated by open reduction with transosseous wiring, but bilateral condylar fractures were treated conservatively. His mouth opening was limited gradually. X-ray examination showed extensive bone union at the left side of TMJ area.<BR>Case 2 was a 5-year-old girl who had fallen down and struck her jaw at the age of four. She had no treatment. Her mandibular movements became limited gradually. X-ray examination showed bone union at the left side of TMJ area.<BR>Case 3 was a 27-year-old male who had suffered fracture of the mandible in a trafic accident at the age of 23. Treatment of the mandibular fracture was the same as for case 1. He had undergone the operation on the TMJ one year later, because of pain in the TMJ and limited opening of his mouth. However, his symptoms did not improve. X-ray examination showed hyperplasia with irregular morphologic change of the left mandibular head and narrowing of the joint space.
