To assess the degree of facial symmetry in patients suffering from unilateral cleft lip, alveolus and palate (UCLAP) by determining differences between the cleft and the non-cleft hemifaces from 3D surface data.
In twenty-two 10-year-old UCLAP patients, who had the lip repaired using the Tennison-Randall technique and did not undergo further revisional surgery, differences were determined between landmarks, surface areas of the upper lip vermilion and nostrils and virtual volumes of midface, nose and upper lip for cleft and non-cleft sides, separately, after having established a plane of symmetry calculated from optical 3D facial surface data.
Statistically significant differences could be found between cleft and non-cleft sides for the nasal landmarks G(lat), G(sup) and La(med), the nostril angle and the virtual volume of the nose (p(Glat)=0.011, p(Gsup)<0.0005, p(Lamed)=0.002, p(nostril angle)=0.036 and p(nose volume)<0.0005, resp.).
Analysis of 3D data shows that complete nasal symmetry is difficult to achieve with Tennison-Randall's lip repair without revisional surgery. Further trials on larger populations of patients will allow a more comprehensive and consistent analysis of the consequence of different methods for cp repair in order to identify the techniques with the best outcome in terms of facial symmetry.
通过从三维表面数据确定唇裂侧与非唇裂侧半脸之间的差异，评估单侧唇、牙槽突和腭裂（UCLAP）患者的面部对称程度。
22名10岁的UCLAP患者，采用坦尼森 - 兰德尔技术修复唇部且未接受进一步修复手术，在根据光学三维面部表面数据计算出对称平面后，分别确定唇裂侧与非唇裂侧在标志点、上唇朱红色和鼻孔的表面积以及中面部、鼻子和上唇的虚拟体积方面的差异。
在鼻标志点G（外侧）、G（上方）和La（内侧）、鼻孔角度以及鼻子的虚拟体积方面，唇裂侧与非唇裂侧之间存在统计学显著差异（p（G外侧）=0.011，p（G上方）<0.0005，p（La内侧）=0.002，p（鼻孔角度）=0.036，p（鼻子体积）<0.0005）。
三维数据分析表明，采用坦尼森 - 兰德尔唇修复术且不进行修复手术难以实现完全的鼻对称。对更多患者群体进行进一步试验，将能够对不同腭裂修复方法的后果进行更全面和一致的分析，以便确定在面部对称方面效果最佳的技术。
