One of the major disadvantages of sagittal arthrotomography of the temporomandibular joint is its limited capability to detect sideways (medial or lateral) disk displacement. Several arthrographic signs, suggesting sideways disk displacement have been described in recent reports. The most important one is the edge sign. In doubtful cases, arthro-CT can be used for depiction of medial or lateral disk displacement.
颞下颌关节矢状面关节造影的主要缺点之一是其检测侧向（内侧或外侧）盘状移位的能力有限。最近的报告中描述了几种提示侧向盘状移位的关节造影征象。其中最重要的是边缘征。在可疑病例中，关节CT可用于显示内侧或外侧盘状移位。
