不完全性腭裂修复术后患者替牙期的颅面特征初探

Craniofacial morphology of patients with isolated cleft palate in the mixed dentition after palatoplasty

目的比较不完全性腭裂患者修复术后与健康儿童替牙期颅面形态的差别,进一步了解不完全性腭裂患者的颅面特征。方法选择20例不完全性腭裂修复术后,处于替牙期的患者作为腭裂组,年龄7～11岁;选择年龄、性别匹配的非腭裂健康儿童35名作为对照组。对两组研究对象的头颅侧位 X 线片进行 X 线头影测量对比分析。结果腭裂组全颅底长、上颌长、下颌有效长度分别为86.48 mm、44.79 mm、65.45 mm,对照组分别为91.27 mm、48.84 mm、70.49 mm,差异均有统计学意义(P<0.001)。结论不完全性腭裂患者颅面部发育不足,呈Ⅲ类骨面型。

Objective To evaluate the craniofacial morphology of patients with isolated cleft palate in the mixed dentition after palatoplasty. Methods Twenty patients （7 to 11 years old） with isolated cleft palate in the mixed dentition were selected. The control group comprised 35 age-matched noncleft children without orthodontic treatment. Cephalometric analysis was carried out to evaluate craniofacial morphology. Results The mean values of total cranial base length, maxillary depth, mandibular effective length in cleft patients were 86. 48 mm,44.79 mm and 65.45 mm, respectively. Those in control group were 91.27 mm, 48. 84 mm and 70. 49 mm, respectively （P 〈 0. 001 ）. Conclusions Underdeveloped maxilla and class Ⅲ skeletal profile were presented in patients with isolated cleft palate.
