Objective.本研究的目的是分析面部软组织变化的差异，尽管相同程度的上颌向前运动，单侧唇腭裂（uCLP）和那些没有，LeFort I截骨术和二次鼻整形术后的患者之间。将12例上颌骨后缩发育不良伴鼻畸形的患者分为两组，A组（uCLP）和B组（对照组），并在相同上颌骨前移的基础上进行比较。A、B组术前、术后均进行X线头影测量和三维平均面部模型测量。计算直线和角度测量值。A组的上朱红和基底红保持不变，但B组增加。在两组中，鼻底对称性得到改善，嘴唇矢状投影增加。3D分析显示，uCLP的外科手术可以提供令人满意的美学结局，但与对照组相比存在一些明显差异。
Objective. The aim of this study was to analyze the differences in facial soft tissue changes, despite the same extent of upper jaw forward movement, between patients with unilateral cleft lip and palate (uCLP) and those without, after LeFort I osteotomy and secondary rhinoplasty.Study Design. Twelve patients with maxillary retrognathic dysplasia and nose deformity were divided in 2 groups, A (uCLP) and B (control), and compared on the basis of the same maxillary advancement. Cephalometry and 3D mean facial model of groups A and B were obtained before and after surgery. Linear and angular measurements were calculated.Results. Upper vermilion and alar base remained unchanged in group A but increased in group B. In both groups, symmetry of the nasal base was improved, and an increase of the sagittal projection of the lips was observed.Conclusions. 3D analysis showed that surgical procedures for uCLP can provide a satisfactory aesthetic outcome, but some differences are evident in comparison with the control group.
