目的：探讨唇封闭功能不全（ILS）对面部软组织形态的影响。方法：选取3-5岁学龄前儿童444名。受试者面部表面的图像是用三维激光扫描仪获得的。在三维面部图像上建立和识别16个面部标志点的坐标，并测量有（wILS）和无ILS（woILS）儿童之间的差异。结果如下：4岁和5岁儿童的矢状面凸面（不包括鼻子）的角度wILS儿童明显小于woILS儿童。鼻突角和唇前突角wills组在各年龄段均显著小于wolls组。结论：ILS患儿鼻下突、唇突向前突出，鼻部较扁平。ILS对面部形态的影响甚至在3岁之前就开始显现。
Objective: To examine whether incompetent lip seal (ILS) influences the form of facial soft tissue. Methods: Four hundred forty-four preschool children 3-5 years of age were selected. The images of the subjects' facial surface were obtained with a three-dimensional laser scanner. Coordinates of 16 facial landmarks were established and identified on the three-dimensional facial images, and the differences between children with (wILS) and without ILS (woILS) were measured. Results: The angle of sagittal facial convexity, excluding the nose, in 4- and 5-year-old children was significantly smaller in wILS children than in woILS children. The nasal prominence angle and the protrusion angle of lips in wILS children were significantly smaller than those in woILS children, at all ages. Conclusion: Children with ILS have anteriorly prominent subnasales and lips and flatter noses. The influence of ILS on facial form begins to appear even before 3 years of age.
