Roentgencephalometry was used for the assessment of the development of clinically important facial characteristics in complete unilateral cleft lip and palate during the prepubertal and pubertal period. Thirty-one patients aged 8 and 11 years and 30 patients aged 11 and 14 years were examined repeatedly. All of them were operated upon and orthodontically treated with the same methods. An unfavorable development of facial convexity, sagittal jaw relations, configuration of the soft profile, and of the prominence of the upper lip occurred during both periods. An improvement of overjet that was attained during the prepubertal period showed a renewed impairment during the period of puberty. The impairment was not caused by the higher facial growth rate, but was attributable to the exhaustion of the compensation and adaptation mechanisms of the dentoalveolar component of the upper jaw produced by the preceding orthodontic therapy. The development of sagittal jaw relations and of facial rotation was not related to the initial patterns of these characteristics, but the possibility of an improvement of the inclination of upper incisors and of overjet was influenced by their initial pattern. During the prepubertal period the development of overjet was not related to the development of sagittal jaw relations or of mandibular growth rotation, as was the case during puberty.
采用X线头影测量法评估青春期前和青春期单侧完全性唇腭裂患者重要临床面部特征的发育情况。对31例8至11岁的患者和30例11至14岁的患者进行了多次检查。所有患者均采用相同方法进行手术和正畸治疗。在这两个时期，面部凸度、矢状颌关系、软组织侧貌形态以及上唇突出度均出现不利发育。青春期前获得的覆盖改善在青春期出现了再次损害。这种损害并非由面部较高的生长速度引起，而是归因于先前正畸治疗导致上颌牙牙槽成分的代偿和适应机制耗竭。矢状颌关系和面部旋转的发育与这些特征的初始模式无关，但上切牙倾斜度和覆盖改善的可能性受其初始模式影响。在青春期前，覆盖的发育与矢状颌关系或下颌生长旋转的发育无关，青春期则不然。
