OBJECTIVE
The objective of this study was to analyze craniofacial morphologic characteristics at the stage of mixed dentition in Chinese children who had received surgery for unilateral complete cleft lip and palate (UCCLP) compared with the healthy population.
MATERIAL AND METHODS
Lateral cephalometric radiographs were taken for 2 groups of individuals: (1) 48 UCCLP patients who had been operated on before 2 years of age, and (2) 60 noncleft peers as controls.
RESULTS
The operated UCCLP groups differed from the control group as follows: reduced cranial base length, less maxillary length, more retrognathic maxilla, retusion of the entire maxilla, more incongruous intermaxillary relation, more concave skeletal profile, and more lingually inclined maxillary and mandibular incisors.
CONCLUSIONS
The operated UCCLP children at the mixed dentition stage showed serious craniofacial deformities and the craniofacial growth was influenced (especially in maxilla).
目的
本研究的目的是分析与健康人群相比，接受单侧完全性唇腭裂（UCCLP）手术的中国儿童在混合牙列期的颅面形态特征。
材料与方法
对两组个体进行头颅侧位X线片拍摄：（1）48例在2岁前接受手术的UCCLP患者，（2）60例非腭裂同龄人作为对照。
结果
接受手术的UCCLP组与对照组的差异如下：颅底长度缩短、上颌长度减小、上颌后缩更明显、整个上颌后移、颌间关系更不协调、骨骼轮廓更凹陷以及上颌和下颌切牙舌倾更明显。
结论
处于混合牙列期的接受手术的UCCLP儿童表现出严重的颅面畸形，并且颅面生长受到影响（尤其是在上颌骨）。
