A study was designed to measure noninvasively the deep temperature of the temporomandibular joint (TMJ) region and corresponding regions of the masticatory muscles at rest. With a transcutaneous probe, the deep thermometry of the right and left anterior (Ta) and the posterior portion (Tp) of the temporal muscles, the mid-portion of the superficial belly of the masseter muscles (Mm), and the TMJ regions were measured. In 20 normal male subjects, the deep temperature of the Ta region (mean 36.342 degrees C), the Tp region (mean 36.345 degrees C), and the TMJ region (mean 36.06 degrees C) was higher than that of the Mm region (mean 35.897 degrees C) at rest. In addition, no differences in the deep temperature were observed between the right and left Ta, Tp, Mm, and TMJ regions at rest. All of the normal subjects showed differences between the right and left TMJ region of less than 0.3 degrees C. In 10 patients with craniomandibular disorders, however, eight patients showed differences of more than 0.3 degrees C between the asymptomatic and asymptomatic TMJ region. Because of high sensitivity and specificity, the deep thermometry measurements can provide useful non-invasive information.
一项研究旨在在静息状态下非侵入性测量颞下颌关节(TMJ)区域以及咀嚼肌相应区域的深部温度。使用经皮探头,测量了颞肌左右前部(Ta)和后部(Tp)、咬肌浅腹中部(Mm)以及TMJ区域的深部温度。在20名正常男性受试者中,静息状态下Ta区域(平均36.342摄氏度)、Tp区域(平均36.345摄氏度)和TMJ区域(平均36.06摄氏度)的深部温度高于Mm区域(平均35.897摄氏度)。此外,静息状态下左右Ta、Tp、Mm和TMJ区域之间未观察到深部温度差异。所有正常受试者双侧TMJ区域的差异均小于0.3摄氏度。然而,在10名颅下颌疾病患者中,8名患者的无症状和有症状TMJ区域之间的差异超过0.3摄氏度。由于具有高敏感性和特异性,深部温度测量可以提供有用的非侵入性信息。
