PURPOSE: The aim of this study was to evaluate use of the axial anchor screw system in the treatment of condylar process @entity174 . @entity1 AND METHODS: Seven adult @entity1 with displaced condylar process @entity174 were treated using axial anchor screw fixation. Indications for surgery were severe dislocation of the condyle and occlusal changes. Clinical and radiologic examinations were performed 6 weeks, 6 months, and approximately 2 years postoperatively (range, 18 to 30 months). Clinical factors recorded were occlusion, range of mandibular movement, and findings on palpation of the temporomandibular joints. Ramus height and angulation between the mandibular ramus and the dislocated condyle were measured and compared with the contralateral side preoperatively and at the last follow-up. RESULTS: The postoperative course was uneventful in most @entity1 . All were free of @entity158 , and the occlusion and facial symmetry were normal. Radiographs generally showed excellent @entity174 reduction. Translation of the condyles on mouth opening was symmetrical. No signs of resorption or @entity571 were evident in most cases. However, some @entity1 had complications. These involved unsatisfactory reduction in one @entity1 causing @entity3061 at the @entity174 line. In another @entity1 bone over the screw fractured and the condyle and the screw tilted in a medial direction. CONCLUSION: Treatment of condylar process @entity174 using the axial anchor screw system is ideal in certain cases. The complications and difficulties seen may be avoidable by appropriate @entity1 selection and techniques.
