The aim of this study was to evaluate, using cone-beam computed tomography (CBCT), the relationship of persistent foramen tympanicum (PFT) with degenerative changes in the temporomandibular joint (TMJ) and the presence of pneumatized glenoid fossae and articular eminences.
Two experienced oral and maxillofacial radiologists evaluated 510 CBCT scans, from which 94 patients were divided into two groups: G1-patients with PFT and G2-control group. The location of the PFT, presence, or absence of degenerative TMJ changes and morphology were evaluated. Similarly, all images were evaluated for the presence of pneumatized articular eminence and glenoid fossa. The Chi-square test and Fisher's Exact test were used for the categorical variables. A multinomial logistic regression model was performed for subgroup analysis. To assess the estimation-chance occurrence of TMJ alterations the Odds Ratio analysis was used.
Statistically significant results were found for erosion, planning, and subchondral cyst. Regarding TMJ morphology, significant results were found for: round, flat, and others. Moreover, it was possible to observe that patients who had the PFT were approximately 48 times more likely to manifest TMJ alterations and approximately 3 times more likely to manifest articular eminence pneumatization.
Since individuals who have FTP have a greater chance of having TMJ and PEA changes, it is important for the dental radiologist to be aware of these signs in CBCT scans for a correct diagnosis.

本研究旨在通过锥形束 CT（CBCT）评估持续性鼓室（PFT）与颞下颌关节（TMJ）退行性改变以及翼状突窝和关节结节气化的关系。
两位有经验的口腔颌面放射科医生评估了 510 例 CBCT 扫描，其中 94 例患者分为两组：G1-PFT 组和 G2-对照组。评估了 PFT 的位置、TMJ 退行性改变的存在或缺失以及形态。同样，所有图像均评估了关节结节气化和翼状突窝的存在。对于分类变量，使用卡方检验和 Fisher 精确检验。对于亚组分析，进行了多项逻辑回归模型。为了评估 TMJ 改变的估计机会发生，使用了优势比分析。
在侵蚀、规划和软骨下囊肿方面发现了统计学上显著的结果。关于 TMJ 形态，发现了明显的结果：圆形、扁平形和其他形状。此外，观察到患有 PFT 的患者发生 TMJ 改变的可能性大约增加了 48 倍，发生关节结节气化的可能性大约增加了 3 倍。
由于具有 FTP 的个体发生 TMJ 和 PEA 改变的可能性更大，因此口腔放射科医生在 CBCT 扫描中注意到这些迹象对于正确诊断非常重要。
