目的
2
评价锥形束CT(CBCT)造影检查对颞下颌关节盘穿孔的诊断价值。
方法
2
回顾分析了2013年12月至2023年1月期间临床诊断为颞下颌关节骨关节病(TMJOA),且同时进行了CBCT造影检查及开放手术的患者。将CBCT造影诊断结果与开放手术探查金标准比较,得出真假阳性和真假阴性关节例数,从而评价CBCT造影诊断关节盘穿孔的整体准确性。
结果
2
共90例患者106侧关节符合本研究纳入标准,其中男性10例,平均年龄36.4岁;女性80例,平均年龄42.6岁,单侧病变74侧,占比82.22%,双侧病变16例,占比17.78%。其中造影剂显影良好94侧,占比88.68%,造影剂显影不良12侧,占比11.32%。CBCT造影结果明确诊断为关节盘穿孔75侧,占比70.75%,手术探查确认穿孔75侧;5例造影剂显影不良,影像诊断考虑可能穿孔,探查确认穿孔5例;影像诊断真阳性率100%;CBCT造影结果明确诊断不存在关节盘穿孔19侧,造影占比17.92%,手术探查确认无穿孔19侧,真阴性率73.08%,7例造影剂显影不良,影像结果未报关节盘穿孔,手术探查存在穿孔7侧,假阴性率26.92%。
结论
2
CBCT造影对颞下颌关节盘穿孔具有较高的诊断准确率,可为临床提供可靠的影像学依据。
Objective
2
To evaluate the diagnostic value of cone-beam computed tomography (CBCT) arthrography for temporomandibular joint disc perforation.
Methods
2
A retrospective analysis was conducted on patients who were clinically diagnosed with temporomandibular joint osteoarthrosis (TMJOA) and underwent CBCT arthrography and open surgery between December 2013 and January 2023. The diagnostic results of CBCT arthrography were compared with the gold standard of open surgical exploration to determine the number of true and false positive and negative cases, thereby evaluating the overall accuracy of CBCT arthrography in diagnosing disc perforation.
Results
2
A total of 90 patients (106 joints) met the inclusion criteria of this study, including 10 males with an average age of 36.4 years and 80 females with an average age of 42.6 years. Among them, 74 joints exhibited unilateral lesions (82.22%), and 16 joints exhibited bilateral lesions (17.78%). Among these, 94 joints (88.68%) showed good contrast medium visualization, while 12 joints (11.32%) showed poor contrast medium visualization. CBCT arthrography clearly diagnosed disc perforation in 75 joints (70.75%), and surgical exploration confirmed perforation in 75 joints. In 5 cases, poor contrast medium visualization was observed, and the imaging diagnosis suggested possible perforation, with surgical exploration confirming perforation in 5 cases; the true positive rate of imaging diagnosis was 100%. CBCT arthrography clearly diagnosed the absence of disc perforation in 19 joints (17.92%), and surgical exploration confirmed the absence of perforation in 19 joints, with a true negative rate of 73.08%. In 7 cases, poor contrast medium visualization was observed, and the imaging results did not report disc perforation, but surgical exploration revealed perforation in 7 cases, with a false negative rate of 26.92%.
Conclusions
2
CBCT arthrography demonstrates high diagnostic accuracy for temporomandibular joint disc perforation and may provide reliable imaging evidence for clinical decision-making.
