Abstract

Patients with TMJ dysfunction often suffer from TMJ noise. However, determining the side at which the noise occurs is not always easy in auscultation or when picking up the noise electrically, because the sound is carried across the bony structure and picked up on both sides. To solve this problem, we utilized a three-directional accelerometer, measuring the sound on both sides in the hope that a difference in measurements would identify the side of the noise. We discovered that time difference between the acceleration peaks for the side originating the sound was shorter than that of the other side. Our report also contains a few observations on the result of this study on patients with plural TMJ noises occurring during one movement of the mandible.

【TMJ噪声发生侧的识别方法研究——多次点击】。
颞下颌关节功能障碍患者常伴有颞下颌关节噪声。然而,在听诊或电测噪声时,确定噪声发生的一侧并不总是容易的,因为声音穿过骨骼结构并在两侧被接收。为了解决这个问题,我们使用了一个三向加速度计,测量两侧的声音,希望通过测量的差异来识别噪音的一侧。我们发现,发出声音的一侧的加速度峰值之间的时间差比另一侧的要短。我们的报告也包含了一些观察结果,本研究的患者多发性颞下颌关节噪音发生在一个运动的下颌骨。
