OBJECTIVES
To determine if the skeletal form of individuals born with oral clefts was associated with maxillary position.
MATERIALS AND METHODS
Lateral cephalometric radiographs of 90 individuals 8 to 12 years old born with or without cleft lip and palate paired by age and sex were used. Skull base length, cranial base angle, cranial deflection angle, and maxillary skeletal length and position were studied. Also, mandibular skeletal length and position, lower anterior facial height, and dental position were defined. Individuals were divided into three groups: 30 individuals born with cleft lip and palate with Class III malocclusion (UCLP Class III), 30 individuals born with cleft lip and palate with Class I malocclusion (UCLP Class I), and 30 individuals born without cleft lip and palate with Class III malocclusion (non-cleft Class III).
RESULTS
When comparing the UCLP Class III group with the UCLP Class I group, there were differences in maxillary position (P < .001) and mandibular position (P = .004) found. No differences were found when comparing the UCLP Class III group with the non-cleft Class III group.
CONCLUSIONS
There are intrinsic factors that affect craniofacial morphology of individuals born with cleft lip and palate.
目的
确定患有唇腭裂个体的骨骼形态是否与上颌位置有关。
材料与方法
本研究纳入了 90 名 8 至 12 岁的个体，这些个体均患有或未患有唇腭裂，并按照年龄和性别进行了配对。研究了颅底长度、颅基底角、颅偏斜角、上颌骨长度和位置，以及下颌骨长度和位置、下前颜面高度和牙位。个体被分为三组：30 名患有唇腭裂伴 III 类错颌畸形的个体（UCLP Class III），30 名患有唇腭裂伴 I 类错颌畸形的个体（UCLP Class I）和 30 名未患有唇腭裂伴 III 类错颌畸形的个体（非唇腭裂 Class III）。
结果
当比较 UCLP Class III 组与 UCLP Class I 组时，发现上颌位置（P <.001）和下颌位置（P =.004）存在差异。当比较 UCLP Class III 组与非唇腭裂 Class III 组时，未发现差异。
结论
患有唇腭裂的个体的颅面形态存在内在因素的影响。
