The temporomandibular joint is a complex synovial joint in the body. It is the area in which the mandible articulates with the cranium. The temporomandibular joint space is located between the articular eminence and the glenoid fossa of the temporal bone at the base of the skull and the condylar process of the mandible. This interarticular space is divided into superior joint space (1.2 ml) and inferior joint space (0.9 ml) by the articular disc. The purpose of this study is to detect and evaluate the variations in the temporomandibular joint space among patients having temporomandibular joint disorders.
In this retrospective study, 60 magnetic resonance imaging scans were evaluated at King Faisal Specialist Hospital in Riyadh, Saudi Arabia, between the years 2006 and 2016. Measurements were done in sagittal view in three areas: anterior, central, and posterior areas. However, coronal view readings were recorded in two different areas: medial and lateral joint spaces. All measurements were recorded at the highest point of the condyle that is perpendicular to the opposing bone. The SPSS program was used for statistical analysis.
The central joint space values were higher than the anterior and posterior joint spaces in both coronal and sagittal views. We also found that joint spaces among male patients were higher than female patients (right side =0.015 and left side =0.006). It is worth mentioning that the number of temporomandibular joint disorder female patients was more than the number of male temporomandibular joint disorder patients (52 females versus 24 males). Additionally, patients who were older than 55 years old had wider joint spaces than patients who were younger than 25 years old.
The central joint space value was the highest among the other joint spaces on both views of magnetic resonance imaging, and the values of joint spaces among males were larger than those of females on sagittal magnetic resonance imaging. Patients with elderly temporomandibular joint disorders showed larger joint spaces than young patients. This study spotlights the importance of magnetic resonance imaging evaluation in temporomandibular joint disorder patients for a better understanding of the clinical evolution of temporomandibular disorders.
颞下颌关节是人体中一个复杂的滑膜关节。它是下颌骨与颅骨相接的部位。颞下颌关节间隙位于颅底颞骨的关节结节和关节窝之间以及下颌骨的髁突。这个关节间隙由关节盘分为上关节间隙（1.2ml）和下关节间隙（0.9ml）。本研究旨在检测和评估颞下颌关节紊乱患者的颞下颌关节间隙变化。
在这项回顾性研究中，我们评估了 2006 年至 2016 年期间在沙特阿拉伯利雅得法赫德国王专科医院的 60 例磁共振成像扫描。测量在矢状面的三个区域进行：前、中、后区域。然而，冠状面的读数记录在两个不同的区域：内侧和外侧关节间隙。所有测量均在与对侧骨垂直的髁突最高点进行。使用 SPSS 程序进行统计分析。
在冠状面和矢状面，中央关节间隙值均高于前、后关节间隙。我们还发现男性患者的关节间隙高于女性患者（右侧=0.015，左侧=0.006）。值得注意的是，颞下颌关节紊乱女性患者的数量多于男性患者（52 名女性对 24 名男性）。此外，年龄大于 55 岁的患者的关节间隙比年龄小于 25 岁的患者宽。
在磁共振成像的两种视野中，中央关节间隙值均高于其他关节间隙值，在矢状面磁共振成像中，男性的关节间隙值大于女性。老年颞下颌关节紊乱患者的关节间隙大于年轻患者。本研究强调了磁共振成像评估在颞下颌关节紊乱患者中的重要性，有助于更好地了解颞下颌关节紊乱的临床演变。
