To evaluate facial morphology characteristics of patients with unilateral complete cleft lip and palate (UCCLP) after cleft palate repair in different periods.
46 nonsyndromic UCCLP patients were chosen as test group and divided into three kinds (under 4-year-old, 4-7-year-old, over 7-year-old) according to periods of palate repair. 38 age and gender matched non-clefts children were involved as control group. 26 cephalometric measurements were measured to evaluate facial morphology of four groups.
Compared with patients who received palate repair before 4-year-old, patients who received repair after 4-year-old had more protrusive ANS point (Ba-N-ANS, Ba-ANS) and less Y-axis angle. Patients who received palate repair after 7-yesr-old had greater A-PMP and ANS-PMP than patients who received palate repair before 4-year-old, patients who received palate repair before 7-year-old had smaller ANS-Me but after had no significant difference when compared with non-clefts.
Whenever palate repair is undertaken in the period of maxillary growth and development, patients' maxillary growth would be restrained, the delayed repair sample have better lower face height, maxillary protrusion, maxillary sagittal length and mandible growing direction when compared with the early repair sample, that is to say, the delayed repair sample have preferable head-face morphology.
评估单侧完全性唇腭裂（UCCLP）患者在不同时期腭裂修复后的面部形态特征。
选取46例非综合征性UCCLP患者作为试验组，根据腭裂修复时期分为三种（4岁以下、4 - 7岁、7岁以上）。选取38例年龄和性别匹配的非腭裂儿童作为对照组。测量26项头影测量指标以评估四组的面部形态。
与4岁前接受腭裂修复的患者相比，4岁后接受修复的患者前鼻棘点（Ba - N - ANS、Ba - ANS）更突出，Y轴角更小。7岁后接受腭裂修复的患者比4岁前接受腭裂修复的患者有更大的A - PMP和ANS - PMP，7岁前接受腭裂修复的患者ANS - Me更小，但与非腭裂患者相比，7岁后接受修复的患者无显著差异。
无论在上颌生长发育期间何时进行腭裂修复，患者的上颌生长都会受到抑制，与早期修复样本相比，延迟修复样本在面下高、上颌前突、上颌矢状长度和下颌生长方向方面表现更好，也就是说，延迟修复样本具有更优的头面部形态。
