[A method for the threedimensional determination of symmetry in the mid-face].

An apparatus to determine normal, traumatic and ontogenic facial asymmetry was developed which scans the mid-face profile three dimensionally, according to the raster principle. Nine horizontal profile lines for the metric and optic comparison of both sides are produced over a computer. The results of the measurements were presented for normal subjects and patients following trauma to the mide-face (total, 100).
