The purpose of this study was to evaluate the influence of orthognathic surgery on articular disc position and temporomandibular disorder symptoms of skeletal class III patients by means of clinical and radiographic evaluation of the temporomandibular joint.
Thirty-six patients with skeletal class III malocclusion, who were treated at Kangnam St. Mary's Hospital between January 2005 and January 2006, were evaluated by clinical examination and pre- and postoperative magnetic resonance imaging.
The change of articular disc position after mandibular setback surgery by means of sagittal split ramus osteotomy was not statistically significant, but it tended to be positioned posteriorly.
It can be suggested that orthognathic surgery does not significantly change the position of the articular disc.
本研究旨在通过对颞下颌关节进行临床和影像学评估，来评价正颌手术对Ⅲ类骨性错牙合患者关节盘位置及颞下颌关节紊乱症状的影响。
对2005年1月至2006年1月在江南圣母医院接受治疗的36例Ⅲ类骨性错牙合患者，通过临床检查及术前、术后磁共振成像进行评估。
经矢状劈开下颌升支截骨术进行下颌后缩手术后，关节盘位置的改变无统计学意义，但有向后移位的趋势。
可以认为正颌手术不会显著改变关节盘的位置。
