Growth of the lips, nose and chin was studied in a mixed longitudinal sample of 82 subjects from the "Nijmegen Growth Study". The age range was between 9 and 14 years with a single measurement at the age of 22 years. Differences in growth pattern between boys and girls are illustrated by mean cumulative growth curves and mean growth velocity curves as well as by contour plots.
