The attainment of normal values was interpreted as the achievement of facial harmony of the various facial proportions. By comparing the pre- and postoperative analysis, a control of the outcome quality of the orthognathic procedures was performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In a total of 160 patients aged 13 to 61 years, the preoperative analysis could be compared with the postoperative Brons-Muli\u00e9 analysis. Postoperative, facial harmony was found for the vertical dimension in 99 cases (62%), for the upper lip dimension in 95 cases (59%), for the lower lip dimension in 138 cases (86%), and for the chin dimension in 118 cases (74%). This corresponded to an improvement of 20% in the vertical dimension, of 27% in the area of the lower lip and of 6% in the area of the chin.
