Three-dimensional computed tomography has been used in both preoperative planning of mandibular distraction osteogenesis and in the evaluation of postoperative resolution of tongue-based airway obstruction. The authors present a case report using software to predict postdistraction airway volume during virtual surgical planning (VSP) of mandibular distraction osteogenesis in a 7 year old. The predicted increase in airway volume derived from VSP was 33.57% (1716 mm(3) preoperatively to 2292 mm(3) postvirtual distraction). Based on the three-dimensional computed tomography, the actual airway volume increased to 2211 mm(3) postoperatively, a 28.85% increase.The implications of this advancing technology are far-reaching. An illustrative case is presented herein to demonstrate the efficacy of the airway prediction and its limitations. The authors believe that, with continued investigation, this novel approach may be a standard feature of all VSP sessions for the treatment of tongue-based airway obstruction.
