This study was designed to investigate maxillofacial morphology in adolescents and adults with unrepaired cleft palate, with or without cleft lip. Twenty-two Chinese patients with unilateral cleft lip and palate (the UCLP group), and 21 Chinese with cleft palate (the CP group) were cephalometrically evaluated and classified into the five ranges established from the means and standard deviations for matched normal Chinese populations. Many subjects in both UCLP and CP groups showed an intrinsic maxillary retrusion and a steeper mandible. The others had nearly normal maxillofacial morphology. The tendency for maxillary retrusion and a steeper mandible became increasingly remarkable with age. In the long axis of upper incisors in subjects with permanent dentition, there were no UCLP subjects with labial inclination, whereas three CP subjects exhibited labial inclination.
本研究旨在调查未修复腭裂的青少年和成人的颌面形态，无论是否伴有唇裂。对22例中国单侧唇腭裂患者（UCLP组）和21例中国腭裂患者（CP组）进行了头影测量评估，并根据匹配的正常中国人群的均值和标准差分为五个范围。UCLP组和CP组的许多受试者均表现出上颌骨内在后缩和下颌骨更陡。其他受试者的颌面形态接近正常。上颌后缩和下颌骨更陡的趋势随着年龄的增长而愈发明显。在恒牙列受试者的上切牙长轴上，没有UCLP受试者出现唇倾，而有3例CP受试者出现唇倾。
