Sixty-seven per cent of the forty-three patients suffering from craniomandibular disorders (CMD) had a vertical condylar asymmetry greater than 3%. After division into two different groups, myogenous and arthrogenous origin of pain, it was found that myogenous patients were younger and showed significantly bigger asymmetry between the vertical heights of the left and right condyles, evaluated on an Orthopantomogram, than the patients with arthrogenous origin of pain (P less than 0.05). The mean vertical condylar asymmetry was 9.10% and 4.83%, respectively. It is suggested that the possible triggering morphological condylar asymmetry on the pathogenesis of a CMD should be recognized at an early stage of the disorders development. The use of a screening protocol and an Orthopantomogram could be of preventive importance in daily practice.
43名患有颅下颌关节紊乱症（CMD）的患者中，67%存在髁突垂直不对称超过3%的情况。将患者分为疼痛源于肌源性和关节源性两组后发现，肌源性疼痛患者较年轻，在曲面断层片上评估显示，其左右髁突垂直高度之间的不对称性明显大于关节源性疼痛患者（P小于0.05）。平均髁突垂直不对称率分别为9.10%和4.83%。建议在CMD发病机制中可能引发的形态学髁突不对称应在疾病发展的早期阶段得到认识。在日常实践中，使用筛查方案和曲面断层片可能具有预防意义。
