To examine the relationship between lip repair and inhibition of maxillary growth, and to investigate the characteristics of upper lip in patients with complete unilateral clefts of lip, alveolus and palate.
Lateral cephalometric radiographs and photographs (anterior-posterior and profile) were taken for 3 groups of patients: (1) 35 complete unilateral cleft lip, alveolus and palate cases in whom only a labioplasty was performed as infants; (2) 47 cases who had both lip and palate repaired; and (3) 37 non-cleft peers as controls.
There was maxillary retrusion in groups (1) and (2). Surface area and height of the upper lip was reduced in both these groups when compared with the normal controls.
Lip repair is a most important factor in the restraint of maxillary growth in patients with complete unilateral clefts of lip, alveolus and palate. And height and projection of the upper lip are reduced following lip repair.
研究唇修复与上颌骨生长抑制之间的关系，并调查完全性单侧唇、牙槽突及腭裂患者的上唇特征。
对三组患者拍摄头颅侧位片及照片（前后位和侧位）：（1）35例完全性单侧唇、牙槽突及腭裂患者，婴儿期仅行唇成形术；（2）47例唇腭裂均修复的患者；（3）37例非腭裂同龄人作为对照。
第（1）组和第（2）组存在上颌后缩。与正常对照组相比，这两组的上唇表面积和高度均减小。
唇修复是完全性单侧唇、牙槽突及腭裂患者上颌骨生长受限的最重要因素。唇修复后上唇高度和突度减小。
