摘　　要：关节音是颞下颌关节紊乱病的主要临床症状之一,正常人群也常有关节音存在,由于其产生机制不同,正常关节及不同类型颞下颌关节紊乱病的关节音各有不同的特点。根据关节音的声谱图特征,从关节音振动能量、频率、振幅、发生时间等方面对关节音进行鉴别,可能有助于判断颞下颌关节的功能状况。本文就关节音产生的可能机制、关节音的研究方法和声谱图的特征作一综述。Temporomandibular joint sound is one of the main clinical symptoms of temporomandibular disorders （TMD）. However, it is also present in most asymptomatic individuals. Because the formation mechanisms are different, the characteristics of the normal joint sound and different types of TMD joint sound are various. Therefore, we can identify the joint sounds according to the energy, frequency, amplitude and occurring time of the vibration on the joint sound sonogram. And that may be useful to determine the TMJ functional status. In this article, the possible mechanism and research methods of TMJ sound, and the characteristics of sonogram were reviewed.
