The double-jaw surgery is frequently desirable to correct skeletal discrepancies and obtain better esthetic results for patients with severe skeletal Class III deformities. Instead of standard surgical principles, an alternative rotation of the maxillo-mandibular complex (MMC) is frequently required for patients with extreme degrees of skeletal discrepancies to achieve optimal facial esthetics. As shown in the case report, the clockwise rotation of MMC was planned for the adult male patient with skeletal class III that resulted in increasing the fullness of paransal area, reducing the lower anterior facial height and decreasing the chin projection by 14 mm. The proper facial proportion, optimal facial esthetics and stable surgical results were achieved in this case. The rotation of the MMC is an accepted surgical design and should be considered for patients that the conventional procedure will result in less than optimal esthetic outcome.
