Evaluation of facial osteotomy with the aid of Moiré contourography.

The Moiré method, a new technique for recording contour lines on the body surface, was applied to the evaluation of facial osteotomy in patients with oro-facial disharmony. The advantages of the methods are three-dimensional, with no contact. Small changes of the facial profile after osteotomies were measured three-dimensionally and the prediction of probable facial contour changes by osteotomies is discussed.
