本研究把３６名单侧完全性唇腭裂术后患者依牙龄分为替牙组及恒牙组。３６名相同年龄分布的正常人为对照组。利用Ｘ线头颅定位后前位片，对单侧完全性唇腭裂患者颅面生长发育的对称性进行研究。研究结果表明，除替牙期乳突点、磨牙点及恒牙期眶外侧壁点，唇腭裂患者颅面双侧对应结构的垂直向差值均大于正常；两个牙龄期所有颅面对应结构的水平非对称率均大于正常人。唇腭裂术后患者颅面发育的不对称不仅仅局限于面中部结构，且有随年龄增大的趋势
In this study, 36 patients with unilateral complete cleft lip and palate patients were divided into two groups according to the age of the tooth group and the permanent tooth group. 36 normal persons with the same age distribution were control group. The use of X-ray cranial positioning of the anterior segment, the unilateral complete cleft lip and palate patients with craniofacial growth and development symmetry study. The results show that in addition to the periodontal mastoid point, molar point and permanent dentition lateral orbital point, the corresponding difference in the bilateral craniofacial corresponding structure of patients with cleft lip and palate is greater than the normal ; all two craniofacial age craniofacial The horizontal asymmetry of the corresponding structures were greater than that of normal people. Patients with cleft lip and palate after craniofacial development asymmetry is not limited to the surface of the middle structure, and with age trends
