Clinical signs and synovial fluid analysis in the temporomandibular joint of mandibular prognathism patients

本研究的目的是通过滑液分析、放射学检查和计算机化下颌运动分析来全面评价下颌前突患者的关节功能。[]95.3pg/100ug SF蛋白)的IL-1β水平高于TMF内乱(ID)患者(330.1()sy.+-。[)347.7 pg/100ug SF蛋白)。SF、IL-6和IL-8水平有低于ID的趋势。所有下颌前突患者无症状TMJ无畸形。计算机化的下颌运动分析系统显示，所有有症状的TMJ患者在正畸手术后均未出现TMJ剪切和/或皱缩。结论：下颌前突错牙合畸形患者的无症状TMJ的炎性介质的SF水平低于ID TMJ

The purpose of this study is to tolally evaluate temporomandibular joint (TMJ) function.of mandibular prognathism patients by synovial fluid analysis, radiological examinations, and computerized jaw movement analysis.Synovial fluid (SF) from TMJs with asymptomatic mandibular prognathism patients showed significantly lower levels (76.7(]SY.+-。[)95.3 pg/100 ug of SF protein) of IL-1 beta than TMF internal derangement (ID) patients (330.1(]SY.+-。[)347.7 pg/100 ug of SF protein). SF IL-6 and IL-8 levels tended to be lower than those of ID.No deformities of TMJ components wererevealed in asymptomatic TMJs of all mandibular prognathism patients. Computerized jaw movement analysis system showed no emergence of TMJ cliking and/or crepitation after orthgnatic surgery in all saymtomatic TMJs preoperatively.In conclusion, SF of inflammatory mediators tended to be lower levels in the asymtomatic TMJs of mandibular prognathism with malocclsion than ID TMJs
