    Journal: J Oral Maxillofac Surg; 2002 Sep; 60(9):996-1002; discussion 1002-3. PubMed ID: 12215982.
    Abstract:
    PURPOSE: We describe a new indication for the sagittal split ramus osteotomy with rigid fixation to treat patients with painful dysfunction of the temporomandibular joint. PATIENTS AND METHODS: Ten patients for whom nonsurgical management failed were found to have a mandibular condyle positioned postero-superior within the glenoid fossa with reduced joint space on corrected-axis tomograms. The sagittal split ramus osteotomy was used to reposition the proximal segment and to increase joint space. Preoperative and long-term postoperative (average, 44.7 months) symptoms and tomographic findings were retrospectively compared. RESULTS: Significant pain relief occurred postoperatively in all patients. One patient had a relapse after initial improvement. No patient developed a malocclusion. The long-term radiographic condyle-fossa relationship tended to return to its preoperative position with no relapse of clinical symptoms, except in the 1 patient. CONCLUSION: The sagittal split ramus osteotomy with rigid fixation is another procedure that can be used to treat painful temporomandibular joint dysfunction by changing the position of the mandibular condyle in the glenoid fossa.
