The authors noted the high prevalence of facial asymmetry and of unilateral amblyopia in some hundred children suffering from chronic neurological conditions. Unilateral changes in muscle tone are responsible for such asymmetry. Amblyopia in itself may cause a facial asymmetry. The dental arcades are little affected even by severe deformities of their underlying bony supports. Dento-maxillary abnormalities are no more severe in these children than in a normal population.
作者们注意到，在数百名患有慢性神经疾病的儿童中，面部不对称和单侧弱视的发生率很高。单侧肌张力变化是造成这种不对称的原因。弱视本身可能会导致面部不对称。即使其下方的骨支撑严重畸形，牙弓也很少受到影响。这些儿童的牙颌面异常并不比正常人群更严重。
