- Results Masticator space involvement is visualized on CT and MRI as effacement of the fat plane, swelling of the masticatory muscles, and erosion of the mandibular ramus. 结果咀嚼肌间隙病变的CT、MRI表现为间隙内脂肪密度影消失,界限欠清,咬肌肿胀,有时可见下颌骨破坏。
- Methods : The electromyography of masticatory muscles was studied in 40 patients with unilateral posterior teeth loss and 40 volunteers with complete dentition as control. 方法: 对40例单侧上颌后牙缺失患者组成的缺牙组和40例牙列完整的自愿者组成的对照组,进行肌电图检查。
- Conclusion : Unilateral posterior teeth loss has effect on the electromyography of masticatory muscles and may play a role in temporomandibular diseases. 结论: 单侧后牙缺失可以对咀嚼肌肌电图造成影响,可能是颞下颌关节疾病的发病原因之一。
- Bruxism is a disorder characterized by grinding and clenching of the teeth, companied with fasciculation of masticatory muscles in nonfunctional status. 磨牙症是在非功能状态下咀嚼肌发生自发性收缩,使上下牙彼此磨动或紧咬的现象。
- In chronic MMM there is atrophy of the jaw muscles, and scarring of the masticatory muscles due to fibrosis may result in inability to open the mouth (trismus). 慢性咀嚼肌肌炎中,下颌肌肉萎缩、咀嚼肌纤维化,这将导致犬只无法张口。
