PURPOSE
The objective of the study was to determine the diagnostic accuracy of panoramic radiographs in the evaluation of pneumatization of the temporal bone, with confirmation of the diagnosis by cone-beam-computed tomography (CBCT) images.
METHODS
Images of 200 patients' digital panoramic radiographies and CBCT were examined by three evaluators regarding the presence or absence of pneumatization on temporomandibular joint (TMJ) fossa and/or articular eminence. When present, the defect was classified as uni- or multilocular, and as unilateral or bilateral. Areas under the ROC curve were compared to assess the accuracy of panoramic radiograph.
RESULTS
The values obtained in the comparisons ranged from Az = 0.67 to 0.55 (Az = area under the ROC curve).
CONCLUSIONS
The panoramic radiograph, is not the exam of choice for detecting the presence of these air cells based on its medium to low accuracy for diagnosis of pneumatized articular eminence and TMJ fossa when compared to CBCT.
目的
本研究的目的是确定全景X线片在评估颞骨气化方面的诊断准确性，并通过锥形束计算机断层扫描（CBCT）图像来确诊。
方法
三名评估人员检查了200例患者的数字全景X线片和CBCT图像，以确定颞下颌关节（TMJ）窝和/或关节结节是否存在气化。若存在，将缺损分类为单房或多房，以及单侧或双侧。比较ROC曲线下面积以评估全景X线片的准确性。
结果
比较所得的值范围为Az = 0.67至0.55（Az = ROC曲线下面积）。
结论
与CBCT相比，全景X线片在诊断气化关节结节和TMJ窝时准确性中等至较低，因此不是检测这些气房存在情况的首选检查。
