The present study aimed to evaluate any relationship between elongated styloid process (ESP) and temporomandibular joint disc displacement (TMJD).
A retrospective cohort study.
Dentomaxillofacial Radiology division of Erciyes University Dental Hospital.
Ninety-four temporomandibular joints (TMJs) of 47 patients were allocated in this study. Intervention-disease: Two experienced dentomaxillofacial radiologists have interpreted all CBCT and MR images. Patients who referred with TMJ disorders were classified according to temporomandibular joint's disc status as normal disc position (ND), displacement with reduction (DWR) and displacement without reduction (DWoR).
Main outcome measures: Interpretation of styloid chain calcification pattern and styloid processes length measured linearly on reconstructed sagittal slices of CBCT. Randomization: Cone beam computed tomography (CBCT) and magnetic resonance (MR) images of 154 patients who were admitted between September 1, 2012 and September 1, 2019. Only 47 of them fulfilled the study requirements. Blinding: Single blind of the outcome measurements and interpretations of MR images.
Total 94 TMJs of 47 patients disc status groups were analyzed and defined as DWoR (n = 25), DWR (n = 32), and ND (n = 37). On multivariate analysis, no statistical significant differences were found between groups in terms of styloid process lengths. Mean SP length and standard deviation of disc status groups (DWoR, DWR, and ND) are 35.5 (± 9.8) mm, 34.6 (± 9.2) mm, and 38.3 (± 8.9) mm, respectively. When patients were grouped individually according to their post-MRI diagnosis, the mean styloid process length in the non-temporomandibular joint disc displacement (non-TMJD) patients (47.9 ± 10.8) was significantly higher than the TMJD patients (36.1 ± 9.3). In this study, there is no intervention to cause any harm or side effects.
Our results indicate that styloid-stylohyoid syndrome may be misdiagnosed with temporomandibular joint disorder (TMD).

本研究旨在评估细长型茎突（ESP）与颞下颌关节盘移位（TMJD）之间的关系。
回顾性队列研究。
埃尔吉耶斯大学牙科医院的口腔颌面放射学系。
47 名患者的 94 个颞下颌关节（TMJ）被纳入本研究。干预-疾病：两名经验丰富的口腔颌面放射科医生对所有 CBCT 和 MRI 图像进行了解读。根据 TMJ 盘的状态，将因 TMJ 紊乱而就诊的患者分为正常盘位（ND）、有复位的盘移位（DWR）和无复位的盘移位（DWoR）。
在 CBCT 的重建矢状位切片上线性测量茎突链钙化模式和茎突长度的解读。
2012 年 9 月 1 日至 2019 年 9 月 1 日期间收治的 154 名患者的锥形束 CT（CBCT）和磁共振（MR）图像。只有其中 47 名符合研究要求。
MR 图像结果测量和解读的单盲。
分析并定义了 47 名患者的 94 个 TMJ 盘状态组为 DWoR（n=25）、DWR（n=32）和 ND（n=37）。多变量分析显示，各组在茎突长度方面无统计学差异。各组的平均 SP 长度和标准差（DWoR、DWR 和 ND）分别为 35.5（±9.8）mm、34.6（±9.2）mm 和 38.3（±8.9）mm。当根据患者 MRI 后的诊断对其进行分组时，非颞下颌关节盘移位（非 TMJD）患者的平均茎突长度（47.9±10.8）明显高于 TMJD 患者（36.1±9.3）。在这项研究中，没有干预措施会造成任何伤害或副作用。
我们的研究结果表明，茎突-茎突舌骨综合征可能会被误诊为颞下颌关节紊乱（TMD）。
