This study was performed to ultrasonographically assess the masseter muscle thicknesses of individuals with disk displacement with reduction.
The thickness of the masseter muscle in 100 patients (28 male, 72 female; average age 34 years) who presented with one-sided temporomandibular joint pain and a clicking sound and were diagnosed with disk displacement with reduction was measured in relaxation and at maximum contraction using ultrasonography.
In the contracted position, the difference in the masseter muscle thickness between the healthy side and the side with disk displacement with reduction was statistically significant (p < 0.05). However, no statistically significant difference was found between the two sides in the relaxed position.
Obvious ultrasonographic changes of the masseter muscle were found in patients with temporomandibular disk displacement with reduction, and these changes might be related to unilateral chewing. Individuals with anterior disc displacement probably chew unilaterally because of pain and clicking.
本研究旨在通过超声评估可复性关节盘前移位患者的咬肌厚度。
使用超声测量 100 例（28 名男性，72 名女性；平均年龄 34 岁）单侧颞下颌关节疼痛伴弹响且诊断为可复性关节盘前移位患者的放松和最大收缩状态下的咬肌厚度。
在收缩状态下，健康侧和可复性关节盘前移位侧的咬肌厚度差异具有统计学意义（p < 0.05）。但是，在放松状态下，两侧之间没有发现统计学上的显著差异。
可复性关节盘前移位患者的咬肌出现明显的超声变化，这些变化可能与单侧咀嚼有关。由于疼痛和弹响，前关节盘移位的患者可能会出现单侧咀嚼。
