Three-dimensional analysis of facial morphology using moiré stripes. Part II. Analysis of normal adults.

This paper presents a system for analysing facial morphology using moiré stripes in 60 normal Japanese high-school students. Analysis of the central region of the face revealed consistent differences between the sexes and between the right and left sides of the face. On the basis of these data, it is suggested that 1 mm difference should be considered permissible between the 2 sides of the upper lip in cases of lip repair in cleft lip and palate patients.
