咀嚼侧偏好（CSP）已被认为是颞下颌疾病（TMD）的病因之一，因为它可以引起颞下颌关节的结构变化。但其与关节隆起倾斜度 (IAE) 的关系尚不清楚。本研究旨在比较患有 CSP 和不患有 CSP 的患者之间的 IAE。对 90 名 TMD 患者（平均年龄 45.6 岁，69 名 CSP，21 名无 CSP）和 20 名无 TMD 和 CSP 的参与者（平均年龄 41.3 岁）的锥形束计算机断层扫描图像进行测量，以比较 IAE 和关节窝深度 (DGF)。IAE 和 DGF 显示所有参与者之间呈正相关。与没有 TMD 和 CSP 的参与者相比，没有 CSP 的 TMD 患者表现出相似的 IAE，但 DGF 值显着更高（p<0.05）；相反，患有 CSP 的 TMD 患者的 IAE 和 DGF 显着较高（p<<0.05）。所有参与者均未观察到 IAE 和 DGF 的双边差异。除了男性 CSP 患者的颅窝较女性更深外，IAE 和 DGF 没有观察到性别差异。患有 CSP 的 TMD 患者似乎有一个深部的关节窝，并且有陡峭的隆起，这可能被认为是一种特征性影像学特征。
Chewing side preference (CSP) has been proposed as one etiology of temporomandibular disorders (TMDs) as it can induce the structural changes of the temporomandibular joint. But its association with the inclination of the articular eminence (IAE) is unknown. This study aimed to compare IAE between patients with CSP and without CSP. Cone-beam computed tomography images of 90 patients with TMD (mean age of 45.6 years, 69 with CSP, 21 without CSP) and 20 participants without TMD and CSP (mean age of 41.3 years) were measured to compare IAE and depth of the glenoid fossa (DGF) IAE and DGF showed a positive correlation among all the participants. Compared with the participants without TMD and CSP, the TMD patients without CSP presented a similar IAE but with a significantly higher value of DGF (p < 0.05); in contrast, the TMD patients with CSP presented a significantly greater IAE and DGF (p < 0.05). No bilateral differences in IAE and DGF were observed in all the participants. Except the male patients with CSP had a deeper fossa than did the female, no differences in IAE and DGF according to gender were observed. TMD patients with CSP seem to have a deep glenoid fossa with steep eminence which might be considered one characteristic imaging feature.
