We sought to investigate the relationship between condylar bony change and disk displacement with respect to the signs and symptoms of temporomandibular joint (TMJ) disorders in patients undergoing orthognathic surgery.
We performed a cross-sectional retrospective study of the pretreatment helical computed tomography scans of 129 orthognathic surgery patients.
Condylar bony change, unilaterally or bilaterally, was found in 35.7% of the subjects and 24.4% of the joints. Disk displacement, unilaterally or bilaterally, was seen in 41.4% of the subjects and 29.5% of the joints. The type of craniofacial deformity was significantly associated with condylar bony change and disk displacement. No association of clinical symptoms with respect to craniofacial deformity, condylar bony change, or disk displacement was found except in the case of TMJ sounds.
The results suggested that craniofacial deformity might be related to TMJ disorders, but the only clinical symptom associated with types of craniofacial deformity was TMJ sounds.
我们试图研究在接受正颌手术的患者中，髁突骨质改变与盘移位和颞下颌关节（TMJ）紊乱的体征及症状之间的关系。
我们对129例正颌手术患者的术前螺旋计算机断层扫描进行了横断面回顾性研究。
在35.7%的受试者和24.4%的关节中发现单侧或双侧髁突骨质改变。在41.4%的受试者和29.5%的关节中观察到单侧或双侧盘移位。颅面畸形的类型与髁突骨质改变和盘移位显著相关。除了颞下颌关节弹响外，未发现颅面畸形、髁突骨质改变或盘移位与临床症状之间存在关联。
结果表明颅面畸形可能与颞下颌关节紊乱有关，但与颅面畸形类型相关的唯一临床症状是颞下颌关节弹响。
