Vertical measurements of the Orthopantomograms of 152 patients were made for condylar and rami heights. The symmetry between the right (R) and the left (L) side was calculated with the formula: [(R-L)/(R + L)]. A statistically significant difference between the patients of a routine dental group and the patients treated for craniomandibular disorders was found regarding condylar height symmetry.
对152例患者的曲面体层摄影片进行髁突和升支高度的垂直测量。用公式[(R-L)/(R + L)]计算右侧（R）和左侧（L）的对称性。结果发现，常规牙科组患者与接受颅下颌疾病治疗的患者在髁突高度对称性方面存在统计学上的显著差异。
