摘　　要：目的　评价单侧完全性唇腭裂患者经上颌前牵引治疗后的软组织侧貌改变。方法　 12例患者接受上颌前牵引治疗 ,根据X线头颅侧位定位片上软组织的测量标志点 ,对治疗前后软组织的侧貌改变进行比较分析。结果　上颌骨前牵引治疗后 ,患者鼻突度有明显改变 ,软组织上颌突度增加了 3.8°(P <0 .0 1) ,代表软组织面突度角也有明显改变 (P <0 .0 1)。而下颌软组织突度矢状方向S Ns SM角减少 1° ,无统计学意义。垂直方向 ,上面高无变化 ,而全面高度增加显著 (P <0 0 1)。结论　上颌前牵引后 ,在矢状方向上软组织突度发生显著变化 ,主要包括轻度的鼻隆起 ,下颌及颏部的后缩也有一定改善。Objective The purpose is to evaluate the soft tissue profile changes in patients with complete unilateral cleft lip and palate treated after maxillary protraction. Method 12 patients with complete unilateral cleft lip and palate were treated using maxillary protraction. Lateral cephalometric films were taken before and after treatment. Soft tissue profile changes were evaluated by comparing the difference of soft tissue landmarks between two films. Results After maxillary protraction, the convex of nose (S Ns PRN) increased significantly ( P <0.001), the convex of maxillary soft tissue was increased by 3.8 degree( P <0.01). The convex of middle face changed significantly ( P <0.01). In mandible angle S Ns SM was decreased one degree ( P >0.05).Vertically, there was no significant difference in upper face height ( P >0.05).Total face height increased significantly ( P <0.01). Conclusion After treatment of maxillary protraction, the soft tissue profile in patients with complete cleft lip and palate improved significantly. [
