Abstract
- Improvement in temporomandibular joint (TMJ) pain and dysfunction occurred in some patients after orthognathic surgery, and one possible explanation is related to these changes in condylar position. The improvement in the occlusion from orthognathic surgery may play a role in improvement of symptoms. The purpose of present study was to investigate the incidence of preoperative and postoperative symptoms of TMJ disorders in patients with orthognathic surgery. The study group consisted of 72 males and 68 females in mandibular prognathism. The total number of 140 patients were carried out SSRO (82 cases), IVRO (14 cases), Le Fort I and SSRO (32 cases), Le Fort I and IVRO (5 cases), and ASO (7 cases). In the patient group with no TMJ dysfunction preoperatively (119 cases, 85%), 14.3% (17 cases) developed a problem postoperatively. In the patient group with TMJ symptom preoperatively (21 cases, 15%), 66.7% (14 cases) solved a symtom postoperatively.
