    Abstract:
    OBJECTIVE: To evaluate the application of lateral lag screw and reduction of articular disk in management of intracapsular sagittle fractures of the condylar process. METHODS: The study group consisted of 16 cases (19 joints), including 10 males (12 joints) and 6 females (7 joints). Condylar sagittal fracture and displaced articular disk were detected in all patients. The condylar segments were repositioned and fixed by using lateral lag screw and the displaced articular disk were repositioned at the same time. The mean postoperative follow-up was 16 months (range 6-28 months). During the follow up, facial nerve function was monitored and radiologic re-examinations were performed to evaluate reposition of condylar process fractures and articular disk, while the mouth opening and occlusion were registered. RESULTS: The reduction of the displaced condylar fragments and articular disks in all patients were excellent on 3D CT and MRI. No severe complications were observed (including permanent facial nerve palsies, malocclusion, ankylosis). Three months after surgery, all patients showed their better mobility with condylar and disk, and mouth opening reached 43 mm on maximum, 32 mm on minimum, with a mean of 37 mm. CONCLUSION: The results by application of lateral lag screw and reduction of articular disk are helpful in anatomical and functional recovery of temporomandibular joint for patients with displaced sagittal condylar process fractures.
