Studies focused on facial development during childhood have been conducted by means of 3D technology to provide modifica-tions of anthropometric parameters. Facial mobility was also considered. This study proposed a 3D approach to facial growth changes. Facial sur-face data of 6 subjects were acquired in T1 (age 7–14 years) and after 7 years (T2), in rest position, and during voluntary movements, by a 3Dlaser scanner. Linear and angular measurements on rest position scans at T1 and T2 were compared. Each mimic scan was superimposed with thecorresponding rest scan. Displacement of significant anthropometric points was measured for each facial gesture and at T1 and T2 statistically com-pared. Vertical measurements were those most influenced by aging. Some measurements of central facial area were consistent over time. The pat-tern of soft tissues displacement for each expression was consistent in T1 and T2. These results may be helpful for missing children identification.
