Abstract：
BACKGROUND: Temporomandibular disorders (TMDs) pose diagnostic challenges, and selecting appropriate imaging modalities is crucial for accurate assessment. This study aimed to compare the diagnostic accuracy and efficacy of ultrasonography (US) and magnetic resonance imaging (MRI) in identifying TMDs.
METHODS: A comprehensive meta-analysis was conducted, including studies that compared US and MRI for TMJ disorder assessments. Fixed-effects models were utilized to calculate pooled odds ratios (ORs) and relative risks (RRs) with 95% confidence intervals (CIs). Heterogeneity was assessed using the chi-squared test and I2 statistic. Newcastle-Ottawa scale was used to assess the methodological quality of the studies included.
RESULTS: Six studies were included, involving a total of 281 participants. The meta-analysis demonstrated that MRI was statistically somewhat better than US in identifying TMJ disorders. The summary OR was 0.64 (95% CI: 0.46-0.90), and the summary RR was 0.80 (95% CI: 0.68-0.95). Heterogeneity among the studies was low (χ2 = 2.73, df = 5, p = .74; I2 = 0%). Demographic variables revealed variations in sample size, gender ratio and mean age across the studies.
CONCLUSIONS: This meta-analysis provides evidence that MRI may be more effective than US in diagnosing TMDs. However, the study is limited by the small number of included studies and variations in demographic variables and study designs. Future research with larger samples and standardised protocols is essential to confirm and strengthen these findings. Understanding the diagnostic accuracy of MRI and US for TMJ disorders will aid clinicians in making informed decisions for effective TMJ disorder assessments and patient management.

摘要：
背景：颞下颌关节紊乱病（TMD）提出了诊断挑战，选择合适的成像方式对于准确评估至关重要。这项研究旨在比较超声检查（US）和磁共振成像（MRI）在识别TMD方面的诊断准确性和功效。
方法：进行了全面的荟萃分析，包括比较US和MRI对TMJ疾病评估的研究。使用固定效应模型以95%置信区间(CI)计算合并比值比(OR)和相对风险(RR)。使用卡方检验和I2统计量评估异质性。纽卡斯尔-渥太华量表用于评估纳入研究的方法学质量。
结果：纳入了六项研究，共有281人参加。荟萃分析表明，在识别TMJ疾病方面，MRI在统计学上比US更好。总OR为0.64（95%CI：0.46-0.90），总RR为0.80（95%CI：0.68-0.95）。研究间的异质性较低(χ2=2.73,df=5,p=0.74;I2=0%)。人口统计变量揭示了样本量的变化，研究中的性别比例和平均年龄。
结论：这项荟萃分析提供了证据，表明MRI在诊断TMD方面可能比US更有效。然而,这项研究受到纳入研究数量少、人口统计学变量和研究设计差异的限制.未来更大样本和标准化方案的研究对于确认和加强这些发现至关重要。了解MRI和US对TMJ疾病的诊断准确性将有助于临床医生做出明智的决策，以进行有效的TMJ疾病评估和患者管理。
