Three-dimensional Camera Imaging in Postoperative Evaluation of Distraction Osteogenesis

Distraction osteogenesis in surgical treatments such as Le Fort advancement osteotomy requires assessment by x-ray or computed tomographic (CT) scan to monitor the degree of advancement.1,2 However, radiation exposure should be avoided in children.3,4 Daily evaluation of the progress of maxillary distraction can be evaluated visually because the soft-tissue profile changes occur after maxillary distraction, but objective evaluation of the soft-tissue profile is necessary. The purpose of this study is to evaluate 3-dimensional (3D) camera imaging as a method following maxillary distraction.
