Clinical photographs, virtual surgical planning (VSP) demonstrations, lateral cephalogram, and analysis of our patient. (A) Initial and 13-month extraoral photographs; (B) initial and 13-month intraoral photographs; (C) preoperative lateral cephalometric films and VSP; (D) postoperative lateral cephalometric films and VSP; (E) VSP procedures; and (F) superimposition of preoperative and postoperative analyses. The preoperative and postoperative lateral cephalometric analyses show that the surgery proceeded uneventfully and in accordance with the VSP. The movements of the landmarks were measured in millimeters. Abbreviations and notes, A, move to anterior position; P, move to posterior position; L, move to left; R, move to right; impact, move to upper position; down, move to lower position.
