OBJECTIVE:To identify the main directions of growth of facial structures in subjects with hypohidrotic ectodermal dysplasia (HED). MATERIALS AND METHODS:The 3D noninvasive facial measurements were collected in 12 subjects (6 boys, 6 girls) with HED during four assessments (at 8, 11, 12, and 15 years) using an electromagnetic digitizer. The modifications of linear distances in the upper, middle, and lower third of the face were analyzed and compared with cross-sectional data obtained in normal healthy coetaneous. For each distance, differential values between the last and the initial data were calculated individually, separately for a first (8-11 years) and a second growth period (12-15 years). RESULTS:In the first time span, the growth of all facial measurements was reduced in HED subjects compared with control subjects. During this interval, most of the HED children underwent a functional and/or prosthetic treatment. During adolescence, the width and height of the lower and upper facial thirds showed a larger growth in HED subjects than in control subjects, while all facial depths and all distances in the middle facial third maintained a reduced growth. CONCLUSIONS:The deviation from normal facial growth of HED subjects tends to lessen with age. Functional and prosthetic appliances may have enhanced facial growth.

目的:确定汗湿性外胚层发育不良(HED)患者面部结构的主要生长方向。
材料与方法:在3次无创面部测量中,使用电磁数字化仪在4次评估(分别为8、11、12和15岁)中对12例HED的受试者(6名男孩,6名女孩)进行了采集。分析了脸的上,中和下三分之一处的线性距离的变化,并将其与正常健康的鲸鱼体内获得的横截面数据进行了比较。对于每个距离,分别针对第一个(8-11年)和第二个生长期(12-15年)分别计算最后和初始数据之间的差值。
结果:在第一时间段内,与对照受试者相比,HED受试者的所有面部测量值的增长均降低了。在此期间,大多数HED儿童接受了功能性和/或假体治疗。在青春期期间,HED受试者的上下三分之二的宽度和高度显示出比对照受试者更大的增长,而面部中三分之二的所有面部深度和所有距离都保持了降低的增长。
结论:随着年龄的增长,HED受试者与正常面部发育的偏差趋于减小。功能性和修复性器具可能会增强面部生长。
