Methods: thirty two post operatives lateral cephalograms, with a accompaniment minimum of six months was submitted to manual tracing, digitalization on DFPlus program and cephalometric analysis. Results: the results indicated that 9 of the 11 available references was statistically different of the norm, although if examine the admitted pattern deviation on the norm, the basis was placed into the same, exception the chin throat angle. Conclusions: the experimental conditions of this study permit to conclude that although the studied population had obtained satisfactory aesthetic-functional results, the cephalometric values doesn’t coincided with that of Legan & Burstone analysis. Therefore, the postoperative results’ assessment must be mainly clinical; and the facial esthetic is not whole relationated with preestablished measurements on cephalometrics analysis.
