[Symmetry of the human midface]

A new measuring instrument called "zygometer" is introduced. This device provides a simple technique for measuring the position of the zygomatic bone and arch allowing for lateral comparison. Standard measurements of the midface were collected from 250 uninjured test subjects. In 80% of the cases a symmetry of up to 2 mm was determined. The research results are presented and discussed with reference to clinical application.
