Routine lateral tomography of the temporomandibular joint has resulted in a three-fold increase in the detection of positive findings. The technique is easily accomplished, eliminates the problem of superimposition of unwanted structures, permits a true lateral view of the condyle and condylar fossa, and allows small articular surface abnormalities to be identified. Although the entrance skin dose to the patient's face in the beam is about two times greater per exposure than that for our previous conventional open and closed lateral views, we believe that the increased dose is reasonable and the resulting improved diagnostic accuracy outweighs this disadvantage.
颞下颌关节的常规侧位断层摄影使阳性结果的检出率提高了两倍。该技术操作简便，消除了不必要结构重叠的问题，能提供髁突和髁突窝的真实侧位影像，还能识别小的关节面异常。尽管每次曝光时射束对患者面部皮肤的入射剂量比我们之前传统的开口位和闭口位侧位片约高两倍，但我们认为增加的剂量是合理的，而且由此提高的诊断准确性超过了这一缺点。
