Imaging Studies

Patients undergoing distraction require a photographic assessment throughout the distraction to assess their progress.

  • Necessary radiographic studies include cephalography, mandibular panoramic (Panorex) imaging, and CT.
  • Not all surgeons recommend 3-dimensional reconstructive scanning.

Several important relationships must be considered before distraction of the mid face is preformed.

  • Quantifying the degree of exorbitism is especially important in syndromic patients.
  • Important relationships include the maxillary plane and the occlusal plane angle.
  • Assessing the anteroposterior deficiency in the mid face in relation to the remaining facial structures is also important.
