The purpose of this study was to clarify which findings in magnetic resonance imaging (MRI) are good predicators of pain and mouth opening limitation in patients with temporomandibular joint (TMJ) internal derangement (ID).
Clinical examinations for pain and mouth opening limitation were conducted for suspected TMJ ID. MRI scans were taken within a week of clinical examinations. On the oblique-sagittal plane image, readings were obtained in terms of the functional aspect of disc position, degree of displacement, disc deformity, joint effusion, and osteoarthrosis. Multiple logistic regression analyses were conducted to identify the predictors of pain and mouth opening limitation.
A total of 48 patients (96 TMJs) were studied, including 39 female patients and 9 male patients whose ages ranged from 10 to 65 years. The resultant data showed significant correlations between pain and the MR imaging of the degree of disc displacement (P<0.05). The probability of there being pain in moderate to significant cases was 9.69 times higher than in normal cases. No significant correlation was found between mouth opening limitation and MRI findings.
We identified a significant correlation between clinical symptoms and MRI findings of ID. The degree of anterior disc displacement may be useful for predicting pain in patients with TMJ ID.
本研究旨在明确磁共振成像(MRI)中的哪些表现是颞下颌关节(TMJ)内紊乱(ID)患者疼痛和张口受限的良好预测指标。
对疑似TMJ ID患者进行疼痛和张口受限的临床检查。在临床检查后一周内进行MRI扫描。在斜矢状面图像上,从盘位置的功能方面、移位程度、盘畸形、关节积液和骨关节炎方面进行读数。进行多因素逻辑回归分析以确定疼痛和张口受限的预测指标。
共研究了48例患者(96个TMJ),包括39例女性患者和9例男性患者,年龄范围为10至65岁。所得数据显示疼痛与盘移位程度的MR成像之间存在显著相关性(P<0.05)。中度至重度病例出现疼痛的概率比正常病例高9.69倍。未发现张口受限与MRI表现之间存在显著相关性。
我们发现ID的临床症状与MRI表现之间存在显著相关性。盘前移位程度可能有助于预测TMJ ID患者的疼痛。
